Description
Technical field
The present invention relates to biotech drug technical field, more particularly to recombinant vaccine and its application.
Background technology
Cancer or malignant tumour are to threaten the killer of human health, and the induced factor of tumour is intricate, we lack so far
The weary profound understanding to its specific Forming Mechanism.It has recently been demonstrated that there is circulation between body immune system and tumour cell
Interaction, i.e., immune system can identify the cancer cell of " nonego " component, and cancer cell can also escape body through a variety of ways
The monitoring and attack of immune system, cause the diffusion transfer of patient's body tumour cell.The molecular mechanism bag of tumor immune escape
Include:Tumour antigen expression is lowered or lost, and tumor cell secretion has the soluble cytokine of immune suppression function, and tumour is micro-
Environment recruits inhibitive ability of immunity lymphocyte, and tumour cell up-regulated expression negativity costimulatory signal etc..Wherein, in tumour
Under the induction of the cell factor such as local microenvironment and interferon gamma, great expression negativity costimulatory molecules in the T cell of activation, this
A little immunosupress regulatory molecules will directly affect the antitumor activity of effector cell's toxic T lymphocyte (CTL), it is killed work(
It can weaken and even lose.Presently found inhibition costimulatory molecules mainly have CTLA4/CD80 (CD86), PD1/PD-L1
(PD-L2), BTLA/HVEM, TIM3/GAL9 etc..
People's apoptosis albumen 1 (Programmed Death-1, PD-1) also known as CD279, it is with two ligands
PD-L1 (B7H1, CD274) and PD-L2 (B7DC, CD273) belongs to immunoglobulin superfamily I type transmembrane glycoproteins together, by endochylema
Area, transmembrane anchor area and extracellular site binding domain three parts are formed.The key structure of PD-1 signal immune suppression functions is mediated, is
Immunity receptor tyrosine conversion motif (Immunoreceptortyrosine-based positioned at intracellular signal transduction area
Switch motif, ITSM), when with coupled receptors, ITSM motifs start tyrosine phosphorylation program to recruit related phosphoric acid
Enzyme, makes signal path PI3K/AKT (phosphatidylinositol3 3 kinase/serine-threonine protein kinase enzyme) dephosphorylation in downstream, from
And cause interruption that cell factor synthesizes and T cell effect insensitive etc..PD-1/PD-L1 signal paths are in normal structure organ
And peripheral lymphoid tissue's low expression or inducible expression, to maintaining immunity of organism tolerance, preventing the generation of autoimmunity disease from having weight
Want meaning;And the high of tumor locus PD-1 molecules is expressed, then the apoptosis of activating T cell is accelerated.
2013, Scientific Magazine authorized the great scientific breakthrough of immunologic test point Blocking therapy year, and immunization therapy is also real
Make it is seen that curing the hope of cancer.Immunologic test point Blocking therapy (Immune Checkpoint Blockade) is applied
Inhibitor blocks the coinhibitory signals path of negativity regulatory T-cell, releases T cell and suppresses and discharge its immunocompetence again.When
The inhibitor of preceding exploitation is mainly Humanized monoclonal antibodies, blocks two important immunologic test point --- cytotoxicities respectively
T lymphocyte proteins 4 (CTLA4) and PD-1.2014, the report such as Herbst is a kind of effectively to block PD-1 ligands PD-L1's
Monoclonal antibody medicine PMDL3280A treats the invalid bladder cancer patients of 65 chemical drug treatments, as a result has 13 in 30 PD-L1 positive patients
Example (43%) produces the effect of obvious tumor suppression tumour, wherein 2 people reach state of an illness complete incidence graph;In addition, in PD-L1 negative patients
In also have 11% response rate.Thus, the anti-tumor immune response advantage of checkpoint blocking drugs is embodied, is controlled for cancer immunity
Treatment provides new Research Thinking.At the same time, there is also some drawbacks that clinical drug application is subject to for monoclonal antibody class inhibitor
Limitation.For example, the tumor tissues immunohistochemistry detection of some patientss is displayed without T lymphocytic infiltration phenomenons, this may be caused
Some patientss monoclonal antibody treatment is invalid;Also there are some patients after anti-CTLA 4 Antybody therapy is received, fatal autoimmunity disease occur
Relevant adverse reaction;In addition, Humanized monoclonal antibodies cost of manufacture is higher, drug cost is expensive.These problems all illustrate
Checkpoint blocking treatment need to establish more perfect indication curer screening sequence and therapeutic scheme, and the PD-1 developed at present
Antibody formation blocking agent can not then guide antitumor active immunity, its blocking agent form waits further to optimize.Documents and materials are shown
Show, a kind of soluble type PD-1 (sPD-1) albumen can identify and combine with ligand PD-L1, can be used as another PD-1/PD-L1 signals
The form of path blocking agent is applied to antineoplastic immune.
(1) biological characteristics of solubility PD-1 molecules
Usually there are two kinds of forms for costimulation albumen:It is anchored on cell membrane or is secreted into extracellular, soluble type molecule reservation
Membrane-type molecules extracellular matches somebody with somebody receptor binding domains, and distal end effector molecule is acted on by blood circulation in a manner of free, participates in adjusting
Save immunity of organism.Now it has proven convenient that natural people PD-1 molecules include above two protein form, and membranous type and soluble type PD-1
(Soluble PD-1, sPD1) all by PDCD1 gene codes, wherein, encoded full length mRNA translation product is membrane-type molecules,
And a kind of mRNA splicing variants for lacking exon 3 then translate directly into sPD1.The another way that sPD1 is formed, it may be possible to
Membranous type PD-1 comes off generation under followed by action of proteolytic enzymes.The IgV-IgC spline structures of sPD-1, mediation and ligand PD-L1 and PD-
The combination of L2, but suppress motif due to lacking intracellular, downstream immunosupress signal can not be started.The detection rheumatoid such as Wan closes
There is the high expression of sPD1 molecules in the knuckle synovia and peripheral blood of the scorching patient of section, while with T such as IFN-γ, IL-4, IL-21
The horizontal rise of cell activation relevant cell factor.
The homology of people and mouse PD-1 and PD-L1 albumen is respectively up to 60% and 70%, and extracellular combination critical sites
Primary sequence it is highly conserved.In vitro test is the result shows that recombined human sPD1 fusion proteins and PD-L1, PD-L2 of mouse have friendship
Combination is pitched, illustrates that people source sPD-1 can also block mouse PD-1 to suppress signal path.
(2) physiological function of soluble type PD-1
Soluble type costimulatory molecules participate in adjust immunity of organism correlative study, include sCD80, sLAG3, sPD1 and
SBTLA etc., these molecules have respective physiological function in virus infection, tumour and autoimmunity disease etc..SPD1 molecules are exempted from
Epidemic disease adjustment effect is in particular in four aspects:1. it is the secretion (IFN- for promoting some activation cytokines on T lymphocytes
γ, IL-2 etc.), while reduce suppressive factor IL-10 and TGF-β;2. specific C D4 can be promoted positive for sPD1 effects and CD8
The propagation of positive T cell, and the expression of the T cell up-regulation suppression apoptogene Bcl-xl activated, subtract t cell proliferation activity
It is weak;3. influence of the flow cytometer detection sPD1 molecules to DC cells, it was observed that CD80, CD86, IL-12 and MHC-II quasi-molecule fluorescence are strong
Degree is obviously improved, and shows that soluble PD-1 can promote the maturation of DC cells;4. sPD-1 can be by there is targeting DC to promote
CD8+The function of T cell.The specific molecular mechanism for being related to sPD1 molecular activation immunity of organism waits to study, but it is considered that its
The performance of physiological function depends on antigen-specific cellular immune response, and single sPD1 molecules are that do not possess specific immunity effect
Answer.
