Description
Technical field
The invention belongs to fungal immunomodulatory protein field, more particularly to a kind of straw mushroom immune modulator FIP-vvo80
And preparation method thereof.
Background technology
There is long history in Asian countries using macro fungi (mushroom) and its active material treatment human diseases, it can
To trace back to B.C. 3000, since it is in immunological regulation and the outstanding performance of anticancer aspect, nearly ten years in western countries
Also gradually it is taken seriously.Past focuses mostly on for macro fungi active matter Quality Research in polysaccharide and triterpene, for protein
Relatively fewer, but the application with biotechnology in drug research and development is studied, particularly to gene, albumen in Chinese herbal medicine
The gradual of relation research gos deep between pharmacological action, and mycoprotein is progressively paid attention to, wherein fungal immunomodulatory protein
(Fungal immunomodulatory protein, FIP), since it is with extensive immunobiologic activity, and receives the country
Outer concern.
Fungal immunomodulatory protein (Fungal immunomodulatory protein, FIP) is from Higher basidiomycetes
Isolated one kind has the small protein of immunoregulatory activity, structure and function and phytolectin and immune ball
Ferritin heavy chain variable region is similar, have promote lymphopoiesis, cell cycle regulation, induce Apoptosis, influence cell because
The immunoregulation effects such as expression, activating cell adhesion molecule and antianaphylaxis of son, possess good potential applicability in clinical practice and
Medicinal health value.From 1989, Japanese Kino was separated to first from ganoderma lucidum (Ganoderma lucidum) fructification
Fungal immunomodulatory protein is named as Ling Zhi-8 (LZ-8), and lives to its gene order, amino acid sequence and immune physiology
Property is determined.Up to the present, share 8 kinds of FIPs to be isolated and purified out, they come from ganoderma lucidum (Ganoderma
Lucidium), Ganoderma tsugae (G.tsugae), purple sesame (G.japoncium), microspore ganoderma lucidum (G.microsporum), sweet tea spirit
Sesame (G.sinense) Ganoderma fornicatum (Fr.) Pat (G.fornicatum), needle mushroom (Flammulina velutipes) and straw mushroom
(Volvariella volvacea) is named as LZ-8 (FIP-glu), FIP-gts, FIP-gja (AY987805) respectively,
FIP-gmi, FIP-sin, FIP-gfo, FIP-fve and FIP-vvo have collectively constituted a new protein families-FIPs.
In FIPs families in addition to gold needle mushroom immunomodulatory protein (FIP-fve) and straw mushroom immune modulator (FIP-vvo), other
FIPs be all isolated in ganoderma lucidum never of the same race, although this explanation is all difference of the ganoderma lucidum due to species, and have
Panimmunity regulatory protein is there is in different immune modulators or even ganoderma lucidum of the same race.Such as leaf popin etc. is from ganoderma lucidum
(G.microsporum) 3 protein are separated in：LZP-1, LZP-2 and LZP-3.Experiment in vitro shows 3 kinds of ganoderma lucidum albumen tools
There is stronger promotion lymphocyte proliferation activity, and SDS-PAGE shows that its molecular weight is different from LZ-8, so they obtain
3 kinds of new Ganoderma lucidum immunoregulation proteins.Such situation is equally happened in straw mushroom.Hsu, H.C. et al. existed except 1997
By isolating and purifying and verifying in the sub- fructification of straw mushroom, and it is sequenced to obtain what is be made of 112 amino acid by direct amino acid
Beyond a kind of straw mushroom immune modulator (FIP-vvo) that molecular weight is about 12.67KDa, it is also possible to which there are other kinds of straw mushrooms
Immune modulator.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of straw mushroom immune modulator FIP-vvo80 and its preparation side
Method screens one kind by comparing bioinformatics methods such as genomes and equally derives from straw mushroom, but gene order and amino acid

The gene order of one straw mushroom immune modulator FIP-vvo80, DNA complete sequence analysis the result shows that, FIP-vvo80 full length genes
339bp。
The albumen belongs to a kind of straw mushroom immune modulator.Its cDNA sequence is subjected to BLAST comparisons in GenBank,
Do not find the gene order similar to its, and by its amino acid sequence in the irredundant protein sequence databank (nr) of NCBI
It carries out BLAST and compares discovery, the albumen is with deriving from ganoderma applanatum (G.applanatum) and microspore ganoderma lucidum
(G.microsporum) similitude of immune modulator reaches 63%, with coming from red sesame (G.lucidum) immunological regulation egg
The similitude of white LZ-8 is 62%, is 57% with needle mushroom (F.velutipes) immune modulator FIP-fve.Illustrate FIP-
Vvo80 is a kind of new fungal immunomodulatory protein, and the gene of coding is a new gene.And this albumen is encoded therefore
Genetic modification and the excellent genetic resources of high efficient expression offer in various heterologous gene expression systems.
It is preferential to select the present invention also provides the recombinant vector for including above-mentioned straw mushroom immune modulator FIP-vvo80 genes
For pET-28b (+).The straw mushroom immune modulator FIP-vvo80 genes of the present invention are inserted into expression vector suitably to limit
Between property restriction enzyme site, make its nucleotide sequence is operable to be connected with expression regulation sequence.One as the present invention is most
Preferred scheme, preferably by straw mushroom immune modulator FIP-vvo80 genes be inserted into EcoRI on pET-28b (+) and
Between NdeI restriction enzyme sites, restructuring large intestine expression plasmid pET-FIP-vvo80 is obtained.

Rule are cultivated to exponential phase.
The Jurkat cell suspension of exponential phase is diluted to 1 × 107Cell/mL is inoculated in 96 by every 200 μ L of hole
Well culture plate respectively plus recombinant immune regulatory protein and expression vector albumen PBS solution, makes the final concentration of 10 μ g/ of total protein
mL.It separately sets negative control group (refinement born of the same parents and culture solution, PBS substitutions sample) and positive controls (only adds PMA, PHA, cell
And culture solution, it is not added with sample).Each sample does 3 parallel holes.48h is cultivated in 37 DEG C of incubators.
Cell culture fluid is suctioned out in 1.5mL centrifuge tubes, 1000rpm/min centrifuges 3min, collects supernatant.According to ELISA
The specification of KIT96T Human IL-2 kits carries out the detection of interleukin-22.
It adds in 100 μ L samples, negative control group (refinement born of the same parents and culture solution, PBS substitutions sample) and positive controls is (only
Add PMA, PHA, cell and culture solution, be not added with sample) supernatant, while standard items human IL-2 is taken, it is diluted to respectively final concentration of
31.52nd, 125,250,500pg/mL as positive control and makes standard curve, does negative control with PBS, each sample is added to do
2 parallel holes.
It is put in 37 DEG C of incubators and cultivates 90min, carefully suction out supernatant, washed 4 times per 350 μ L cleaning solutions of hole, is inverted
On filter paper, empty dry liquids, pat dry for the last time as far as possible.
100 μ L biotinylated antibody working solutions are added in per hole, is put in 37 DEG C of incubators and cultivates 60min.Cleaning solution board-washing
Ibid.
100 μ L enzyme conjugates working solutions are added in per hole, is put in 37 DEG C of incubators and cultivates 30min.Cleaning solution board-washing is same as above.
100 μ L developing solutions are added in per hole, are put in dark reaction 10-20min in 37 DEG C of incubators.
100 μ L terminate liquids are added in per hole, are immediately placed in microplate reader, light absorption value is measured in 450nm and record reading, in 5min
Complete this step operation.It makes standard curve and calculates IL-2 contents in sample.
Result of study shows that 1 μ g recombinant immune regulatory proteins FIP-vvo80 promotes human leukemia cell's Jurkat cell point
Interleukin-22 (IL-2) content is secreted in 68.404pg.
