Description

A kind of recombinant plasmid, its recombinant plasmodium for building and its application

Technical field

The present invention relates to the cellular immunotherapy field of tumour, more particularly to a kind of recombinant plasmid, its restructuring malaria for building Protozoon and its application, the structure of recombinant plasmodium specially based on recombinant plasmid and its in the treatment of anti-liver neoplasm Using.

Background technology

Hepatocellular carcinoma (Hepatocellular carcinoma, HCC), account for primary carcinoma of liver ratio 85% is arrived 90%.It is one of five common big cancers of the world, fatal rate in all tumours ranking first three.The data display whole world is annual new Increase liver cancer patient 782,500, while there are 745,500 patients to die from liver cancer every year.At present, it is clinically used for the skill of liver cancer treatment Including surgery excision, orthotopic liver transplantation, TACE and local RF therapy etc., these methods are to early stage HCC for art Patient has certain curative effect.But patient often has found too late, 50% liver cancer patient is not appropriate for using these conventional methods.Together When, one term of patient survival rate is less than 50%.The defect of traditional treatment means is more, including cuts off incomplete, toxic and side effect greatly, easily Recurrence etc..In addition, the medicine of targeted therapy liver neoplasm, including Sorafenib and Bevacizumab etc., there is also treatment secondary The problems such as effect and patient survival are short.Therefore, the medicine for researching and developing new treatment liver neoplasm is very active demand.

At present, biological immune treatment is that one kind is widely recognized as and promising oncotherapy means, most of means master Tumour cell is killed by activating in patient's body specific C D8+T lymphocytes.Adoptive treatment includes chimeric Antigen receptor T cells (CAR-T) treatments are widely studied and participate in clinical practice, but this for individual Therapeutic modality spend time and money it is all very huge, not all people is receptible.At present, by vector expression Tumour specific antigen, and it is considered as one feasible honest and clean to activate internal specific cellular immunity come the method to neoplasm growth The approach of valency, which includes tumor vaccine.In terms of liver neoplasm vaccine research, by AFP (alpha fetal protein, Alpha-fetoprotein) DC (dendritic cell, BMDC) vaccines and GPC3 polypeptide vaccines be completed the clinical II phases, it is raw Rate is deposited all to be significantly increased, it is this raising and cell-specific toxic T lymphocyte (cytotoxic T-lymphocyte, CTL) reaction has significantly association.More tumor vaccines on liver cancer are all obtained very on DNA vaccination, polypeptide vaccine and DC vaccines Much progress.However, these vaccines there is also a universal problem, the exactly caused cell for liver tumor antigens is exempted from Epidemic disease is very strong but does not possess the continuation of specific immune activation, and selects a kind of good tumour antigen carrier perhaps to solve well Certainly this problem.

HCC specific antigens are widely found and for the immunization therapy of tumour.Including phosphatidylinositols albumen The albumen of glycan 3 (glypican 3, GPC3), it is that Pilia etc. has found by 1 research of undue growth syndrome patient 's.GPC3 expression high in liver cancer tissue, and do not expressed in normal liver tissue, it is a kind of carcinomebryonic antigen of new hepatocellular carcinoma. Research shows that GPC3 albumen can be activated including the cytotoxic T lymphocyte for GPC3 in human body and Mice Body (cytotoxic T-lymphocyte, CTL), without causing autoimmunity, this CTL often participates in the target for tumour cell Reacted to killing.For the antibody of GPC3, polypeptide vaccine and CAR-T treatments have come into in-depth study, wherein GPC3 Polypeptide vaccine has been completed the clinical II phases, and its overall survival has significantly pass with the GPC3 specific immune responses of machine vivo activation Connection.

One immunotherapy of tumors based on antigenic activation vivo immuning system, generally requires a good expression and carries Body.The wherein more carriers of application include DNA, RNA, defective virus and bacterium.They can activate strong in vivo exempting from Epidemic disease react but not persistently, this may with immunity of organism remove and they can not continue to replicate in vivo exist it is relevant.One good Good Antigen Expression Vectors should include following two abilities：One is to swash the intravital strong specific CTL for antigen Reaction；Two is the presence that this specific CTL reaction can be lasting in vivo and performance tumor-killing effect.Numerous studies table Bright, some viruses or bacterium infection can well suppress tumour growth.Meanwhile, it is also wide that protozoan is used for oncotherapy General research, including Infection of Toxoplasma Gondii and taper worm.Meanwhile, plasmodium can activate very strong internal innate immune reaction.Plasmodium Can be used as a kind of natural adjuvant, some compositions such as GPI (the glycosyl phosphatidylinositol of itself Anchors), genomic DNA and malarial pigment can be used as pathogen associative mode molecule (pathogen-associated Molecular patterns, PAMPs) recognized immediately by body immune system, and activate immediately internal macrophage, DCs, Natural killer (NK) cell, gamma delta T cells, natural killer T (NKT) cell, CD4+T and CD8+T cells.And It is concluded that the natural and acquired immunity of these activation can be used to suppress the growth of tumour.We herein propose and utilize plasmodium It is have certain foundation as the immunization therapy carrier of HCC：1, Infected With Plasmodium can swash intravital Th1 reactions, and it is right It is most important for the CTL of tumour antigen in activation；2, although red blood cell lacks major histocompatibility antigen I (major Histocompatibility complex class I, MHC I), this has no effect on it and produces the CTL for tumour antigen anti- Should, research shows that DCs and macrophage are involved in and activate ctl response in vivo for plasmodium antigens；3, plasmodium is in itself In parasitic red blood cell in vivo, what it can be long-term is present in vivo, this long-term expression for being conducive to antigen and release, for a long time Swash intravital ctl response in ground.
