Come further to describe in more detail the present invention referring now to following specific embodiment, these specific embodiments should not be construed as by any way and limit the scope of the invention.
Embodiment
Recombined human Cpn10
For the test described in the following embodiment 1 to 4, as people such as Johnson, described in 2005 (the J BiolChem 280:4037-4047), recombined human Cpn10 (GenBank registration number X75821) produces in escherichia coli, and its N-end is an alanine residue.Measure purity>97% by SDS-PAGE.Only before using, the aliquot sample of Cpn10 is thawed.In the rhodanese refolding chemical examination of GroEL mediation, the Cpn10 of all batches has shown the mole active (data not shown) identical with escherichia coli GroES.
Embodiment 1-produces antiviral cell factor IFN β in the presence of PolyI:C
Test the selective agonist of working as with TLR3 to measure, during PolyI:C (polyinosinic acid-polycytidylicacid) administering drug combinations, the effect of the generation of Cpn10 enantiopathy poison cell factor interferon-beta (IFN β).
As people such as Johnson, described in 2005 (the J BiolChem 280:4037-4047), be to test among the RAW264.7 (ATCC registration number TIB71) at mouse macrophage.In brief, the RAW264.7 cell is with 2 * 10 5Cells/well is seeded in 24 orifice plates, and overnight incubation (37 ℃, 5%CO 2).Recombined human Cpn10 (with the concentration between 10 μ g/ml to the 200 μ g/ml) or buffer are added in the cell 2 hours with double, and (San Diego is CA) to the final concentration of 100 μ g/ml for tlrl-pic, InvivoGen to add polyI:C then.After 24 hours, collect supernatant and use description (Cat No.42400-1, the R﹠amp of specific ELISA according to production firm; DSystems Inc, Minneapolis MN) analyzes IFN β level.
As shown in fig. 1, the RAW264.7 cell that does not stimulate does not have and can discharge in the culture supernatant by detected IFN β.Do not having under the situation of Cpn10, stimulating with the polyI:C of 100 μ g/ml the IFN β of 292pg/ml is discharged in the RAW264.7 culture supernatant.Adding causes the IFN β level in the dose dependent ground increase culture supernatant from the ever-increasing Cpn10 of dosage of 10 μ g/ml to 200 μ g/ml, reaches the top level of 900pg/ml when 150 μ g/ml Cpn10.
The antiviral activity of embodiment 2-RAW264.7 cell conditioned medium liquid
The cell culture supernatant that will obtain from the test described in the top embodiment 1 is freezing and be kept at-20 ℃, is used for reducing (CPER) in L cell pathological changes effect afterwards and measures analyzing total antiviral activity (total burst size of I type interferon).
In brief, 3 * 10 4The L cell inoculation is in the 96-orifice plate, and it is adherent to carry out to leave standstill 4h at 37 ℃.Double IFN standard substance and detection supernatant are added in the culture plate with half-log10 serial dilutions.The IFN field of activity of standard substance diluent is from 1-10 4IU/ml.Culture plate overnight incubation 15h removes culture medium, and with Semliki Forest virus (Semliki Forestvirus) with tissue culture ID 50100 times of titres be added in each hole.Culture plate was hatched under 37 3 days, and the pair cell vigor is marked then.Every culture plate contains not to be had IFN or detects the contrast of two row's cells of supernatant as maximum cell death.Measure the IFN titre with respect to NIH's standard (National Institutes of Health standard) Ga02901511, as the IFN concentration that 50% cell is provided protection.As shown in Figure 2, add Cpn10 and cause in the presence of polyI:C, dose response increase significantly (being issued to maximum at 100 μ g/ml Cpn10) takes place in the release of I type interferon.
Shown data show that (wherein viral nucleic acid can be released) gives Cpn10 under the situation of viral infection among the embodiment 1 and 2, or when with TLR3 agonist co-administered, cause stimulating the antiviral immunity of higher level.
NF-kB activation in the HEK293 cell of embodiment 3-expression TLR7
Research people Cpn10 regulates the ability via the signal conduction of Toll sample receptor TLR7 in human embryonic kidney cell line HEK293.People such as the stable cell lines of the HEK293 of expression TLR7 and TLR4 such as Latz set up described in 2002 (the J Biol Chem 277:47834-47843), and with every hole 2 * 10 4The density of cell is seeded in the 96-well culture plate.After the grow overnight, in order to measure the NF-kB activation, cell reports that with NF-κ B-luciferase construction is (according to people such as Latz, 2002, JBiol Chem 277:47834-47843) transient transfection, this construction comprise by drive 5NF-kB site that the Lampyridea luciferase genes expresses and structural active Renilla luciferase report subbase because of artificial report formed of polymer.
After cell culture spends the night, give cell simultaneously with recombined human Cpn10 separately or with one of following reagent with the final concentration of 50 μ g/ml: TLR7 selective agonist resiquimod R848, thiophosphate CpG oligonucleotide (MWG Biotech) (TLR9 selective agonist), TLR4 selective agonist lipopolysaccharide (LPS) or protein kinase C activation thing phorbol 12-myristinate 13-acetas (PMA), in contrast.
Dual by using then-luciferase assay report subsystem (Dual-LuciferaseAssay Reporter System), description (Promega according to production firm, MadisonWI) and assay plate reading photometer (Perkin Elmer) measure uciferase activity, measured NF-kB activation and quantitatively in back 5 hours in stimulation.
The result is presented among Fig. 3, is expressed as NF-kB activation multiple.When not stimulating, (use culture medium separately), do not induce the NF-kB activation.On the contrary, in the concentration range of 0.32-40 μ M, TLR7 selective agonist R848 induces the NF-kB activation doubly above 5-through TLR7.But in the presence of 50 μ g/ml Cpn10, this activation has reduced about 2-doubly.
NF-kB activation in the HEK293 cell of embodiment 4-expression TLR9
Also in the HEK293 cell, study the ability of people Cpn10 adjusting via the signal conduction of Toll sample receptor TLR9.Measure as described in example 3 above.
Measure among the clone separately for two at the HEK293 cell of the expression TLR9 of stable transfection.The result is presented among Fig. 4.Do not having not induce the NF-kB activation under the situation about stimulating (using culture medium separately).But with 0.08-10 μ M concentration range activation HEK-TLR9, induce NF-kB activation doubly up to about 33-with CpG DNA.In the presence of 50 μ g/ml Cpn10, this activation has reduced 5-to 10-doubly.
For further research Cpn10 to the HEK293 cell of expressing TLR9 reactive effect to CpG DNA, use Cpn10-12.5 μ g/ml, 25 μ g/ml, 50 μ g/ml and the 100 μ g/ml of variable concentrations to be similar to above-mentioned test (see figure 5).Observed Cpn10-mediation effect (Fig. 4) above these results have confirmed, and illustrated the dose response of Cpn10-mediation effect to the conduction of TLR9 signal.
Embodiment 5-human peripheral blood mononuclear cell's release of cytokines
In order to determine that Cpn10 regulates the ability of release of cytokines in the former generation people cell, uses isolating human peripheral blood mononuclear cell (PBMC) from healthy volunteer's donor.As people such as Johnson, 2005 (J Biol Chem 280:4037-4047) are described, separate PBMC by the buoyant density gradient centrifugation from the blood of heparinization.
As people such as Latz, described in 2004 (the Nature Immunol 5:190-198), use separation PBMC that anti--BDCS-2-APC post (Miltenyi) handles half to remove plasma cell sample dendritic cell (PDC).PDC is the main source of I type interferon IFN α in the PBMC colony.Known PDC expresses TLR7 and TLR9, and is the key cells type that the mankind are used to discern single-chain nucleic acid.
For the PBMC of PBMC that contains PDC and removal PDC, two kinds of cells are all with 10 6The density of living cells/ml is seeded in the 96-orifice plate with 200 μ l, and as people such as Johnson, cultivates described in 2005 (the J Biol Chem 280:4037-4047).In brief, add the final concentration of Cpn10 to 1 μ g/ml, 10 μ g/ml or 50 μ g/ml, culture plate is hatched 1 hour before adding LPS (non-repurity or repurity).Cell is at 37 ℃ and 5%CO then 2Further hatched 20 hours down.Collect supernatant and use the description (R﹠amp of specific ELISA according to production firm; D Systems, Inc., Minneapolis, MN) generation of analysis proinflammatory cytokine TNF-α (Fig. 6) and anti-inflammatory cytokines IL-10 (Fig. 7).
As shown in Fig. 6 and 7, when lacking LPS, use culture medium or Cpn10 not to induce the generation of TNF-α or IL-10 separately.
The LPS (0.01-10ng/ml) that adds repurity in untreated PBMC culture causes the generation of TNF-α, and in the presence of up to 10 μ g/ml Cpn10, this generation dose response ground reduces (maximum 32%) (Fig. 6 A).But in the PBMC that removes PDC, Cpn10 has lost the influence of the generation of TNF-α (Fig. 6 B).Therefore, Cpn10 needs the existence of PDC to the effect of the generation of the inductive TNF-α of LPS-, and this effect disappears when lacking PDC.This discovery is somewhat wondrous, because PDC does not express TLR4, therefore the stimulation of LPS is not reacted, thereby shows that Cpn10 may be indirect to the regulating action of the signal conduction of TLR4 guiding.
Under the situation of IL-10 (Fig. 7), supernatant from PBMC proves when Cpn10 exists, the generation of IL-10 increases, although prove from the supernatant of the PBMC that removes PDC, the dose response of the generation of IL-10 (until 10 μ g/ml Cpn10) increase (Fig. 7 B) than the PBMC that is untreated with PDC in viewed increase (Fig. 7 A) degree high.
Embodiment 6-Cpn10 is to the activatory adjusting of TLR3
This research is to be used for determining to compare with other TLR, and whether Cpn10 differentially regulates the bonded reaction to TLR3, but the interactional target of its indication molecule.
Specific agonist can excite the activation of two kinds of downstream signal pathways to the stimulation of TLR, MyD88-dependency or dependent/non-dependent.MyD88 is a kind of for the very general adapter molecule of all TLR except that TLR3.The function of this molecule is that IL-1R-associated kinase (IRAK) and TNFR-correlation factor 6 (TRAF6) are raised together with activation I κ B (IKK) α β γ kinases complex, and this complex phosphorylation I κ B α causes that nuclear translocation and DNA combine with NF-κ B then.The MyD88-dependent/non-dependent activation of TLR relates to the activation of the adaptive son (TRIF) that contains the Toll/IL-IR domain of inducing IFN-β.This has caused the activation of NF-κ B and IFN regulatory factor 3 (IRF3) to postpone, thereby causes generation and the IFN-inductivity expression of gene of IFN-β.The combination of TLR3 mainly activates the TRIF path, and TLR4 can activate MyD88-and two kinds of paths of TRIF-dependency.One of purpose of this research is to determine to compare with other TLR, and whether Cpn10 can regulate because the kinetics of the reaction that the TLR3 activation causes, thereby and provides some information for target and the model of action of Cpn10.
6.1 general material
Cpn10 lot number CH003 and GroES (Invivogen) use or use not together with LPS (Sigma) and Poly (I:C).The cell line of using comprises RAW264-pNifty2-LUC and RAW264.7.
6.2 result
6.2.1Cpn10 do not suppress the NF-kB activation by TLR3
The mouse macrophage like cell is the RAW264.7 plasmid stable transfection that driven by ELAM1 promoter (RAW264-pNifiy2-LUC).The ELAM1 promoter is near 5 NF-kB sites and respond the activation of nuclear translocation and NF-κ B transcription factor in the cell and drive luciferase and report sub-expression of gene.As shown in Figure 8, the existence of very wide concentration range Cpn10 can not change the kinetics of the inductive NF-kB activation of TLR3-in the RAW264-pNifty2-LUC cell that stimulates with Poly (I:C).Poly (I:C) is the synthetic analogues of double-stranded RNA, and its molecular pattern is relevant with viral infection, activates NF-κ B by the interaction with TLR3.Dose response ground increases the generation of I type IFN 6.2.2Cpn10 respond the combination of TLR3 and TLR4
RAW264.7 cell and Cpn10 preincubate 2 hours stimulated 24 hours with LPS or Poly (I:C) then.Point is collected cell conditioned medium liquid at this moment, and (people such as Hamilton, (1996) J Immunol 156 (7): 2553) use cytopathy to reduce bioassay (cytopathic effect reduction bioassay) and analyze IFN α/β antiviral activity as mentioned previously.As shown in following Fig. 9, in the presence of Cpn10, by TLR4 (LPS) or TLR3[Poly (I:C)] stimulate and can raise I type IFN in 24 hours.
The RAW264.7 cell is with 2.5 * 10 then 5/ ml is seeded in aseptic 24 orifice plates, and adherent 16-20 hour.Pair cell preincubate in the presence of titrating Cpn10 uses LPS (TLR2/4) or Poly (I:C) to stimulate then 4 or 6 hours.The collecting cell lysate, and down freezing or handle immediately and be used to use Dynabead directly to carry out mRNA to separate at-70 ℃.MRNA carries out RT-PCR with reverse the transcribing of oligomerization (dT) primer with Superscript III First-Strand SynthesisSystem.The cDNA that obtains uses mice IFN β special primer to increase in PCR.In order to confirm that the equivalent template is added in each reaction and confirms to have carried out consistent amplification, each sample is transcribed GAPDH (glyceraldehyde-3-phosphate dehydrogenase) and increased.On agarose gel, separate the PCR product, and after bromination second pyridine dyeing, develop as shown in Figure 10.
Except data from mouse macrophage cell line RAW264.7, as shown in Figure 11, proved that also the human PBMC who stimulates with Poly (I:C) shows, in the presence of Cpn10, the generation of I type IFN (IFN-α) increases.
6.2.3Cpn10 escherichia coli homologue, GroES can not increase Poly (I:C)-inductive IFN-β and produce
The specificity that increase Poly (I:C)-inductive IFN-β produces in order to determine the Cpn10-mediation detects escherichia coli Cpn10 homologue, GroES.As shown in Figure 12, GroES can not regulate Poly (I:C) by the inductive IFN-β generation of TLR3.
6.2.4 wash then with the Cpn10 preincubate, eliminated the dose response increase of the generation of Poly (I:C)-inductive IFN-β
Stimulate in the mensuration at LPS, before adding LPS, wash by PBS then, do not influence the ability that Cpn10 regulates the NF-kB activation with the Cpn10 preincubate.But as shown in Figure 13, in Poly (I:C) measured, RAW264 cell and Cpn10 preincubate had greatly reduced the generation of the IFN-β of Cpn10 dose response increase Poly (I:C) stimulation then by the PBS washing.
6.2.5Cpn10 to Poly (I:C)-or the adjusting of LPS-induced reaction need the positive feedback of I type interferon path
The feature that has the mice of null mutation in the IFNAR1 of I type IFN receptor (interferon associated receptor 1) composition is, increase corresponding with susceptibility to viral infection, lack antiviral response fully, and lost the reaction of the antiproliferative of IFN α/β people such as (, (1995) Proc.Natl.Acad.Sci.USA 92:11284) Hwang.IFNAR1 deficient mice (IFNAR1/-) lacks constitutive character IFN activity, and have aspect the ratio of the hematopoietic cell that comprises macrophage and the reaction unusual.
Use from wild type (wt) or IFNAR1-/-mice the macrophage (BMM) of isolating derived from bone marrow, come the effect of earlier external back interior evaluating Cpn10 in IFN " pre-swash (priming) " reaction.Separate BMM and in the presence of the Cpn10 of dose titration, activate with one group of TLR agonist (Poly (I:C)-TLR3 or LPS-TLR4).Collect supernatant after 24 hours, and use BD Mus inflammation CBA and Mus IFN β ELISA test kit analysis of cells factor level.Result from these mensuration shows that Cpn10 produces the regulating action of (Figure 14) and the inductive TNF-α generation of LPS-(Figure 15) to Poly (I:C)-inductive IFN β, and it is essential reacting through the positive feedback of IFNAR1 receptor.
These data link together IFN feedback network and Cpn10-mediation activity, have further confirmed from result in the body of Mus endotoxemia research.In this pyemic mouse model, mice with 100 μ g Cpn10 through intravenous administration pretreatment 30 minutes, intravenous injection 10 μ g LPS then.1.5 collect serum after hour, and use the generation of BD Mus inflammation CBA and IFN β elisa assay proinflammatory cytokine.As shown in Figure 16, with the remarkable reduction (p<0.05) of the common mice serum TNF alpha levels of handling of Cpn10, relevant with the remarkable reduction (p<0.01) of serum I FN β level.
6.3 discuss and conclusion
At least a exception that the NF-κ B of Cpn10-mediation regulates pattern relates to the activating cell by TLR3 part Poly (I:C).In this TLR3 system, find Poly (I:C) stimulation of Cpn10 response cell and the NF-kB activation is not had effect.
In addition, find that Cpn10 can respond Poly (I:C) and induce concertedness ground to increase the generation of I type interferon.Be that Cpn10 has participated in the adjusting of sharp in advance or feedback circuit reaction to this obviously unusual a kind of explanation.For example, I type interferon has been presented in the LPS-regulation and control reaction or directly or (for example, pass through SOCS1) indirectly and play a significant role.This is the major progress of understanding in the mechanism of action of Cpn10, because it shows that Cpn10 swashs in advance and reduces proinflammatory cytokine by alleviating the early stage cell that is caused by I type IFN, as TNF α.
The adjusting that embodiment 7-Cpn10 infects mice Semliki Forest virus (SFV)
This series of studies is used for determining whether the administration of Cpn10 influences the fatality rate of Semliki Forest virus in the mouse model (SFV), and whether Cpn10 responds the TLR activation and the generation of adjusting I type IFN.
This body inner model relates to the systemic infection of Semliki Forest virus (SFV) with the preliminary adjusting of determining I type IFN antiviral activity.Can in newborn mice, carry out this model, all infected comprising brain at all interior organs, in 4-6 days, cause death according to dosage, so advantage is sensitivity and the violent degree that infects.Perhaps, this model can detect in adult rats, because the generation of I type IFN is arranged, adult rats is less to the susceptibility of virus.It being understood that behind viral infection in first 24-48 hour that the generation of IFN causes that virus titer reduces.This model can carry out " chronic " response analysis, comprises serum analysis and immunne response.
This in vitro study comprises the influence that a series of mensuration regulating action that the pair cell factor produces to detect Cpn10 response TLR activation is swashed by macrophage in advance, comprises relatively the bone marrow macrophage from WT and IFNAR deficient mice fresh separated.
7.1 material and method
(in 50mM Tris, 150mM NaCl, endotoxin<0.01EU/ml) uses Cpn10 lot number CH003 with 5.0mg/ml.Dilution preparation buffer comprises 50mM Tris and 150mM NaCl.Pam3cys and polyI:C are from Invivogen.Mice is C57BL/6.
For studying in the body, the perspective study that relates to titration of virus in mice is to determine suitable viral lot number and dosage.For whole research, every group is used 10-13 Mus, and each viral dosage uses 3 groups of mices.Each organizes following the processing: virus (A) is only arranged; (B) Cpn10 of virus+concentration A; (C) Cpn10 of virus+concentration B.Approximately the newborn mice intraperitoneal injection Cpn 10 (or preparation buffer) and the SFV in 6-9 days ages, and foster by its mother.In addition, adult rats (wt type and IFNAR deficiency) the intraperitoneal injection SFV in age in 6-8 week, per 12 hours intraperitoneal injection Cpn10 in first week of virus injection, its dosage uses fixed dosage.
For in vitro study, adopt Cpn10 response TLR activation and influence and comparison WT and IFNAR defective macrophage that regulating action that the pair cell factor produces is swashed by macrophage in advance.Macrophage (BMM) from the derived from bone marrow of WT and IFNAR deficient mice is handled under the Cpn10 of range of doses with TLR agonist pam3cys (TLR2), polyI:C (TLR3) and LPS (TLR4).
7.2 result
The data of ex vivo newborn rat viral infection research show, the survival rate of the SFV infecting mouse of handling with Cpn10 significantly increases.This research comprises the following newborn C57BL/6 mice in 6-9 days ages of respectively organizing: A group: SFV (n=13); B group: SFV+Cpn10 20 μ g (n=13); C group: SFV+Cpn10 50 μ g (n=13).
B group and C group lumbar injection 20 and 50 μ gCpn10, (after 3 hours) inject 50 μ l SFV (30x TCID50) to all three groups then.Mice is housed in its mother, and carefully nursing in entire test.The standard indication of monitoring these newborn mice health status blanking time (12/24 hour) carefully with rule comprises activity situation, health, behavior etc.
In the time of 72 hours, 54% and 69% 20 and 50 μ g Cpn10 handle mice and still survive, and survival rate is 15% (Figure 17) in untreated mice and compare.Notice that also the mice in the maximum dose level group gets around, other two groups then very unhealthy, lies on one side.In the time of 84 hours, all mices of only handling with SFV all die from the infection of virus, and 31% B group and C group mice still survive.
7.3 discuss and conclusion
As 72 hour datas as seen, the administration of Cpn10 has prolonged the survival rate behind the viral infection in dosage dependence mode.In infection back 96 hours, with the mice of Cpn10 injection 18% survival is arranged, and all untreated mice are all dead in the time of back 88 hours in infection.In two Cpn10 processed group, be 50% and 70% at the mice survival rate of infection in the time of back 72 hours, compare that survival rate is 18% in the untreated fish group, this species diversity is very significant under the situation that gives heavy dose of virus.It should be noted that also this result obtains behind the Cpn10 single-dose.These data show that Cpn10 has induced the antiviral protective effect.
Embodiment 8-Cpn10 and bunch associating of CD14-dependent/non-dependent LPS receptor
The plasma membrane of cell is made up of the heterogeneous thing in a plurality of sides (lateral heterogeneity), speckle (patch) and micro structure territory.These film micro structure territories or lipid raft are rich in glycosyl sphingolipid and cholesterol, and relevant with the cell processes of film sorting and signal transduction and so on.The inventor thinks that in the process that the LPS signal clusters Cpn10 can concentrate on the lipid raft to destroy the signal conduction by directly combining with TLR4 or with one of other members that cluster.
8.1 material and method
The cell marking that is used for FRET.MonoMac 6 cells (human monocyte cell line) 100 μ l mixture labellings of donor cross-linking antibody (Cy3) and receptor cross-linking antibody (Cy5).For the labelling of Cpn10, use anti--Cpn10 rabbit polyclonal antibody.Cell is used 4% formaldehyde fixed 15min then with PBS/0.02%BSA rinsing twice.Fixed cell is in order to prevent the contingent reorganization again of protein in the test process.
Co-focusing imaging.Cell is at Carl Zeiss, and Inc.LSM510 Laser Scanning Confocal Microscope (Axiovert 200 fluorescence microscopies are housed) is gone up and used the imaging of 1.4NA 63x Zeiss object lens.Use LSM2.5 image analysis software (Carl Zeiss, Inc.) analysis image.Use suitable filter set to detect Cy3 and Cy5.Use typical exposure frequency (less than 5s) for image acquisition, use the Cy5 optical filter not observe fluorescence, use the Cy3 filter set also not detect Cy5 fluorescence from the sample of Cy3-labelling.
FRET measures.FRET is the Noninvasive imaging technique, is used for determining the molecule nearness.FRET can take place on the distance of 1-10nm, and can effectively increase the resolution of optical microscope to molecular level.It relate to energy from the excited state non-radiation type of donor molecule be transferred to (Wu and Brand (1994) Anal.Biochem.218:1-13) on the suitable receptor.6 powers of distance (Kenworthy and Edidin (1998) Journal of Cell Biology 142:69-84 that is inversely proportional between the speed that energy shifts and donor and the receptor; Kenworthy and Edidin (1998) Gelb, M.H. (Ed.) " molecular biological method (Methods in molecular Biology) " .HumanaPress Inc, Totowa, NJ pp 37-49).Energy shifts the efficient of (E) according to r and R 0(distinctive Distance) define:
E=1/[1+(r/R 0) 6][1]
In this research, use (Kenworthy and Edidin (1998) Journalof Cell Biology 142:69-84 as mentioned previously; Kenworthy and Edidin (1998) Gelb, M.H. (Ed.) " molecular biological method (Methods in molecular Biology) " .Humana PressInc, Totowa, NJ pp 37-49) method measure FRET.In brief, sample shifts the increase (taking off cancellation) that detects to donor fluorescence behind the complete photobleaching of acceptor molecule with donor and receptor cross-linking antibody labelling, energy.Use is only faded the required minimum time of (bleach) Cy3 so that measure with the cell of 26ic-Cy3 probe mark.Adopt arc light to use the Cy3 optical filter Cy3 to be faded by the continuous agitation that is set at 5 minutes.Under these conditions, Cy5 is not faded.The FRET image is calculated in increase by following formula donor fluorescence behind the receptor photobleaching:
E (%) * 100=10,000 * [(Cy3 fade back-Cy3 fade before)/Cy3 fade back] [2]
The conversion coefficient of use 10,000 extends to E the scale of 12-bit image.
8.2 result and discussion
In first group of data shown in the table 1, FRET is used for determining to participate in the acceptor molecule concentration of the inductive cell activation of LPS (MonoMac6 cell) in the lipid raft.By carrying out FRET experiment, might study Cpn10 (lot number P003-04 or CH003), Hsp60, escherichia coli GroES and other molecules whether with lipid raft co (co-localising).FRET measures is to the cancellation of taking off of donor fluorescence behind the complete photobleaching of acceptor fluorescence group.The increase of donor fluorescence shows because energy shifts after destroying receptor, donor fluorescence in the presence of receptor by cancellation.The use positive control comes the energy transfer efficiency in the detection system, i.e. transfer between the different epi-positions on mAbs to GM1 (ganglioside, the related molecule of the lipid raft) molecule shows that maximum energy transfer efficiency (E%) is 37 ± 1.0.Can use the negative control between FITC-GM1 and the rhodamine-MHC, it shows does not have tangible energy to shift (3 ± 0.4) yet.This background FRET value is considered to because two kinds of species all exist with high concentration by FRET was produced at random.

10.2 result
10.2.1.TLR zygotic induction Cpn10 promoter
The RAW264.7 cell carries out transfection with the sub-construction of report, and the generation of luciferase is under the control of Cpn10 promoter in this construction.Reorganization IFN γ, TNF-α and the IL-1 β of purification detect as non-TLR agonist.(43 ℃, 30min) cell of handling proves that the Cpn10 promoter has significantly induces, and turns back to baseline values (Figure 18 A) during 18h when putting the recovery time of 6h with the moderate heat shock.Induce the Cpn10 promoter with determining TLR agonist dose dependent subsequently, observe maximum activation (Figure 18 A and Figure 19 C) after 20 hours.Optimize agonist concentration then to induce maximum promoter reaction (Figure 18 B-G).
Relatively the reaction to TLR and non-TLR agonist shows that the Cpn promoter activity has unique characteristic curve (Figure 18 H).Observe as the reaction to TLR2,7 and 9 part, Cpn10 has tangible rise, shows relevant with MyD88-dependent T LR signal transduction pathway.Use can adopt the TLR part (TLR3 and 4) of TRIF-dependent signals pathway then not observe the Cpn10 promoter significant rise.And non-TLR agonist IFN γ, IL-1 β and TNF-α can not induce the substance of Cpn10 promoter to raise, and show the specificity that has aspect the control to a certain degree of transcribing at Cpn10.
Another evidence of transcribing as the inductive Cpn10 of TLR-, use the PCR in real time analysis to show that LTA has induced Cpn10mRNA to the stimulation of RAW264.7 cell with having caused concentration dependent, when 18h, reach maximum and induce, stimulate back 24h to be back near baseline values (Figure 18 I).
10.2.2. discharge from cell in conjunction with back Cpn10 at TLR
In order to check when standing suitable stimulation, whether Cpn10 discharges from cell, and the inventor stimulates the RAW274.7 cell with LTA, the existence by ELISA monitoring endogenous Cpn10 and be released into Cpn10 in the culture medium by cell.The analysis of cellular lysate shows that the cell of LTA processing and the interior Cpn10 level of cell of control cells change very little (Figure 19 A).But the analysis of culture supernatant shows that then the more unprovoked control cells of solubility Cpn10 has increased by 3 times (Figure 19 B) behind 30h.In addition, the extracellular Cpn10 level that produces of irritation cell changes in time with the Cpn10 promoter activity and the increase seen is relevant (Figure 19 C).These data show that the new synthetic Cpn10 of a part that produces is discharged by cell under the condition of immune stimulating.Accept the culture supernatant analytical proof of the cell (the RAW264.7 cell of RAW264.7 or pCAT/LUC-CPN-transfection) of slight, moderate or severe heat shock (HS), with compare the gathering seldom of extracellular Cpn10 (Figure 19 D) with LTA stimulated cells supernatant.These data show that Cpn10 is induced with assistance mitochondrial protein misfolding by HS, and specific immunity excites the extracellular accumulation that causes Cpn10.
In order to obtain the evidence that Cpn10 can be conditioned in disease, the inventor has detected the patient's who suffers from chronic inflammatory disease Cpn10 baseline serum level, and itself and healthy volunteer's cohort are compared.As shown in Figure 19 E, the Cpn10 cyclical level of suffering among the patient of rheumatoid arthritis (is respectively 1.32ng/ml ± 1.41, n=23 apparently higher than multiple sclerosis patients, psoriatic or health volunteer; 0.44ng/ml ± 0.46, n=46; 0.55ng/ml ± 0.52, n=25; 0.45ng/ml ± 0.32, n=24).Therefore each Cpn10 serum levels and individual occurent inflammation and/or disease levels are relevant.No matter whether be to cause, be clear that very Cpn10 accumulates in the extracellular environment, and some cytositimulation can strengthen its discharge owing to the post-stimulatory zest of immunocyte in passive release after the lysis or the inflammatory excitation process discharges.
10.2.3.Cpn10 the kinetics of restricted T LR signal conduction
The inventor has checked recombinant C pn10 whether can limit the inductive signal of part of other Toll sample receptors.The Cpn10 preincubate of this report daughter cell system and optium concentration 2 hours, use various TLR parts (its scope is from gram-positive bacterium Peptidoglycan (PGN) and fat techoic acid (LTA) to synthetic RNA and DNA motif) to stimulate then, stimulated cells is compared when lacking exogenous Cpn10, causes the inductive luciferase activity of NF-κ B-obviously to reduce.Except synthetic TLR3 part polyinosinic acid-polycytidylicacid (poly (I:C)), in the cell culture with every other tested TLR ligand stimulation, the existence of Cpn10 causes the inhibition (Figure 20 A) of luciferase activity 20-80%.These results show that Cpn10 can regulate the intensity by the immunne response signal that part produced of most of TLR.
Can trigger MyD88-dependency and the reaction of dependent/non-dependent signal cascade with the LPS irritation cell.MyD88-dependency cascade reaction is that all TLR are shared except TLR3, and relates to NF-κ B and mitogen-activated protein(MAP) (MAP) kinases (MAPK), comprises the terminal kinases (JNK) of p38, extracellular signal-regulated kinase (ERK) and c-Jun N-.The terminal point of two paths is startup and dynamic (dynamical) adjustings of immunne response.Cpn10 regulates the NF-kB activation and cytokine produces the incident that is experienced in order to illustrate behind the irritation cell, and the inventor has analyzed the phosphorylation level that participates in the key protein of map kinase signal path.As shown in Figure 20 B-D, in the human PBMC of mouse macrophage cell line (RAW264.7) and fresh separated, Cpn10 dose response ground reduces the phosphorylation level of the inductive p38 of LPS, ERK1/2 and JNK1/2.Because inducing of the inflammatory cascade reaction that the activation of MAPK path and cytokine produce is closely related, these digital proofs in the inductive cytokine of part produces, the variation during the variation of Cpn10-mediation is reacted from the TLR signal cascade.
In order to confirm the activity of Cpn10 generation by the caused cytokine of people's cell of the fresh separated of multiple TLR ligand stimulation, the inventor is with Cpn10 or without the PBMC 1h of Cpn10 pretreatment from healthy donors, and the TLR ligand stimulation of the selected scope of usefulness is 20 hours then.Use the cytokine levels in ELISA or fluidic cell bead microarray art (CBA) the analysis of cells culture supernatant then.As shown in Figure 20 E, in the presence of Cpn10, be suppressed by the inductive cytokine generation of agonist (comprising TNF-α, IL-1 β, IL-6 and the IL-10) institute of TLR2, TLR2/6 or TLR4 (PGN, LTA, zymosan, LPS).Although it should be noted that Cpn10 mediation to slightly the inducing of the generation of the inductive IL-10 of LPS-, it responds digital proof other TLR part and reduces the generation of IL-10.Equally, compare, in the presence of Cpn10,, cause that the generation of TNF-α reduces, and increase IFN α with agonist and the imiquimod or the CpG ODN stimulation PBMC of TLR7 or 9 with the control cultures that does not have Cpn10.
10.3 discuss
The Cpn10 that this research has not been recognized before having disclosed is as the effect of immune endogenous regulator.Through the TLR of receptor system rather than by TNF-α, IFN γ or IL-1 beta receptor irritation cell, induced Cpn10 promoter and can the proteic generation of detected Cpn10 in the culture medium of extracellular.The human PBMC of cell activation (estimating by the NF-kB activation), MAPK phosphorylation and mouse cell line and fresh separated that the addition agent quantitative response ground restricted T LR-of recombinant C pn10 drives is in external generation cytokine.
The result of Cpn10 is induced in these proof immunologic injuries (insult), and the data that show the restriction inflammatory reaction size of Cpn10-mediation, provides strong evidence to prove, Cpn10 is the important member to the very important negative feedback path of immunne response network.
Embodiment 11-stimulates the inductive change that TLR4 is expressed of back Cpn10-at LPS
The inventor has managed to determine the influence that Cpn10 expresses TLR4 in the RAW264 cell, so that check stimulates back Cpn10 whether can influence the surface expression of TLR4 at LPS.
11.1 material and method

Exist or do not have in the suspension of 100 μ g/ml Cpn10 the specified time of cell culture.Cell transfer is to the 10ml test tube then, and counting gathers group and also is suspended in the fresh culture again.100 μ l cell suspension are transferred to Eppendorf pipe (10 6Cell/pipe) in.Carry out 4 hours Cpn10 at the Eppendorf pipe that places incubator and handle and the LPS stimulation, mixed lightly in per 15 minutes.Cell washs 3 times with PBS/0.2%FBS.Anti--Mus TLR4-biotin (1 μ l is in 50 μ l PBS/0.2%FBS) or control antibodies (anti--Mus IFN-γ-biotin) were hatched on ice 1 hour with cell.Cell washs 3 times in 1ml PBS/0.2%FBS, seals 45min with 50 μ l PBS/10%FBS down at 4 ℃ then.Add streptavidin-PE with 1/100 diluent then, and continued to hatch 1 hour on ice.After 3 washings, cell fixation is in 1% paraformaldehyde/PBS, and use Cell Quest software is analyzed on FACS Caliber.
11.2 result
Cpn10 and RAW264 cell are hatched and were not changed the TLR4 expression in 4 hours.Use anti--Mus TLR4/MD-2-biotin to use streptavidin-PE to be easy on the surface of RAW264 cell, detect TLR4 (Figure 21) then.Control antibodies can not show tangible dyeing (data not shown).Cpn10 handled 4 hours or the processing of contrast buffer all can not change the TLR4 expression.
The influence of LPS downward modulation TLR4 and Cpn10.Add 2ng/ml LPS and make the TLR4 of adding LPS after 2 hours express slight minimizing (Figure 22), 20ng/ml LPS causes that TLR4 expresses almost completely disappear (Figure 23).Cpn10 is hatched the behavior that change to add TLR4 behind the LPS in 4 hours indistinctively.Extend to when spending the night when Cpn10 handles, to compare with the cell (Figure 24 and 25) that buffer is handled, TLR4 expresses and reduces (Figure 24 and 25) slightly.When giving cell 2ng/ml LPS, the minimizing more remarkable a little (Figure 24) that the TLR4 of LPS-mediation expresses in the cell that Cpn10 handles.When cell was handled with 20ng/ml LPS, TLR4 expressed disappear basically (Figure 25) in all groups.
11.3 discuss and conclusion
By active minimizing of LUC that Cpn10 processing in 4 hours is mediated, cause that the inductive NF-kB activation of LPS-reduces 30-50%.This effect can not be because the TLR4 down-regulated expression of Cpn10-mediation is caused, because this processing is very little to the expression change of TLR4.May be remarkable a little after 4 hours Cpn10 handle by the downward modulation that 2ng/ml LPS is mediated, more remarkable certainly after the Cpn10 processing is spent the night.These results show that Cpn10 can change and add the kinetics that TLR4 expresses behind the LPS.

12.2 result
The activation of the HIV-LTR of TLR agonist induction.Digital proof among Figure 26 the Cpn10 ability of in mouse macrophage RAW264-HIV-LTR-LUC cell, regulating the NF-kB activation, this cell is with the TLR ligand stimulation of finite concentration scope.We have detected the part of a large amount of TLR, comprise the LPS (being described as stimulating TLR2 and TLR4 simultaneously) of ultrapure LPS (only TLR4) and non-repurity, from the LTA (TLR2) of two kinds of gram-positive bacteriums (bacillus subtilis and staphylococcus aureus) with from the PGN (TLR2) of above-mentioned two kinds of gram-positive bacteriums.In addition, cell is used from the isolating preparation of the cell wall of yeast saccharomyces cerevisiae, zymosan (TLR2/TLR6) and synthetic double-stranded RNA, and poly (I:C) stimulates, and above-mentioned poly (I:C) can be in conjunction with TLR3 and by its irritation cell.Cell also detects after stimulating with CpG DNA (TLR9) or imiquimod (R837), and imiquimod (R837) is a kind of low-molecular-weight synthetic molecules, its in the presence of Cpn10 through TLR7MyD88-dependency path activating cell.Data show is after detected four kinds of TLR (TLR2,4,7,9) combination, and Cpn10 can induce the activation of regulating NF-κ B.
Figure 27 has described the largest percentage by the inductive luciferase activity inhibition of Cpn10 in the RAW264-HIV-LTR-LUC cell of various TLR ligand stimulations.Although the reaction pattern of tested most of parts is all closely similar, promptly on average suppress 50% HIV-LTR activation, as if Cpn10 do not respond poly (I:C) and change the inductive NF-kB activation of TLR3-.And Cpn10 is limited to the NF-κ B inhibitory action of the activatory cell performance of yeast cell wall preparation zymosan, is approximately 20%.
The influence of the phosphorylation of signal protein in the Cpn10 pair cell.LPS has stimulated RAW264 cell activation signal transduction pathway in several cells comprise IkappaB kinases (IKK)-NF-κ B path and three kinds of mitogen-activated protein kinases (MAPK) path: extracellular signal-regulated kinase (ERK) 1 and 2, the terminal kinases (JNK) of c-Jun N-and p38.In farther downstream, these signal transduction pathway activate many transcription factor, comprise NF-κ B and AP-1, and they induce the gene of coding inflammatory mediator in phase then.In order to estimate the influence of Cpn10 to these signaling systeies, the inventor has measured and has existed or do not exist under the situation of Cpn10, with p38, the JNK1/2 of phosphorylation and the level of ERK1/2 in 30 minutes the cell of LPS stimulation.The inventor has shown each these member's of Cpn10 dose response ground restricting signal pathway the inductive phosphorylation of LPS-(Figure 28).
In order to confirm Cpn10 to produce the activity of cytokine with fresh separated people's cell of multiple TLR ligand stimulation, the inventor uses the PBMC 1h of Cpn10 pretreatment from healthy donors, uses the TLR ligand stimulation 20h of selected scope then.Use ELISA or fluidic cell bead microarray to measure cytokine levels in the cell culture supernatant then.As shown in Figure 29 A-D, in the presence of Cpn10,, comprise that TNF-α, the inductive cytokine of IL-1 β, IL-6 and IL-10 institute produce and reduced by the agonist of TLR2 or TLR4 (PGN, LTA, zymosan, LPS).Equally, the data indication among Figure 29 E is compared with the control cultures of not using Cpn10, with agonist and the imiquimod or CpG (ODN2216) the stimulation PBMC of TLR7 or 9, causes that production of cytokines reduces in the presence of Cpn10.
The Cpn10 preincubate washs the ability that does not influence the inductive NF-kB activation of Cpn10 restriction LPS-then.The inventor was verified in the past, used Cpn10 and RAW264-HIV-LTR-LUC cell preincubate 2 hours before stimulating with LPS, made the dose response reduction of luciferase activity reach optimization.As shown in figure 30, proved also now before LPS stimulates and Cpn10 preincubate 2 hours that carry out the PBS washing then, the luciferase activity (as measuring of NF-kB activation) that does not change the Cpn10-mediation reduces.
Non-TLR swashs the moving inductive NF-kB activation of agent of fclfcl.In order further to characterize the activity of Cpn10, the inventor has detected the regulating action of Cpn10 to many non-TLR agonist.As the part of this non-TLR testing program, in the presence of Cpn10, the RAW264.7 cell stimulates 6 hours (Figure 31) with low endotoxin (2.24EU/mg) the reorganization Mus IFN-γ of 1-10ng/ml.The collecting cell supernatant also uses elisa assay TNF-α.Find that Cpn10 can promote the inductive TNF-α of IFN-γ to produce.When cell and Cpn10 preincubate before IFN-γ stimulates in the time of 2 hours, this remarkable synergistic function of the generation of TNF-α is enhanced.Exist at Cpn10 under the situation of 2 hours or 4 hours, in lysate, also be measured to the higher inductive luciferase level of NF-κ B-with the RAW264-HIV-LTR-LUC cell of IFN-γ stimulation.
12.3 discuss and conclusion
The dynamic (dynamical) ability of Cpn10 adjusting macrophage that the inventor is verified to the reaction of multiple TLR (comprising TLR2,4,7 and 9)-ligands specific, therefore and proved the influence of phosphorylation of the signal transduction molecule of the upstream that Cpn10 produces NF-kB activation and cytokine, above-mentioned signal transduction molecule is the MAPK family member of signal conductive protein, comprises ERK, JNK and p38.The inventor also has been presented at by in the activatory cell of LPS, and Cpn10 dose response ground reduces the level of endocellular phosphorus acidify MAPK.
Digital proof in the present embodiment is adjusted in the kinetics that the innate immunity in the macrophage of the many TLR ligand stimulations of external use is replied the Cpn10 dose response.By the inductive maximum horizontal that suppresses the NF-kB activation of the Cpn10-of these molecules triggerings be: after with TLR7 agonist (R837) stimulation RAW264-HIV-LTR-LUC cell line, be about 80%.Under another kind of numerical range, adding Cpn10 with the concentration range of 10-100 μ g/ml can not influence the bonded kinetics of yeast cell wall preparation zymosan and TLR2/6 above 20%.
The pattern that reduces at least a exception of NF-kB activation for Cpn10 comprises the caused activation of polyinosinic acid-polycytidylicacid (poly (I:C)).Poly (I:C) is the synthetic analogues of double-stranded RNA, and its molecular pattern is relevant with the viral infection that activates NF-κ B through the interaction with TLR3.Cpn10 responds this agonist and the generation of dose response ground increase I type interferon, and does not limit the activation signals of NF-κ B.
