A kind of Antigenic Peptide chain group for treating tumour and its application in drug

Technical field

It is more particularly to a kind of for tumour individuation biology the invention belongs to malignant tumour biological immune technical field of pharmaceuticals The Antigenic Peptide chain group of immunization therapy and its application in drug.

Background technology

At present, global Cancer Mortality rises increasingly, and the death rate is high, poor prognosis.National Cancer Center whole nation tumour Study on prevention office exists《International journal of cancer》Largest In China scale cancer Survival data Macro or mass analysis data are issued to show, in 5 years survival rates of state's cancer are 30.9%, far below developed country's level；The survival rate of rural patient is only City patient's simultaneously Half.In developed country, prostate cancer, breast cancer occupy the majority, and in China, the cancers such as lung cancer, gastric cancer, liver cancer are more common, hair Sick rate and the highest cancer of the death rate are lung cancer.The traditional therapies therapeutic effect such as operation, chemotherapy, radiotherapy is limited, patient 5 years Survival rate is still relatively low；Especially eliminating side effect of radiotherapy and chemotherapy to is big, and patients ' life quality is poor, and survival rate is low.

Biological immune treatment is the new treatment side of future therapeutic tumour by body immune system killing tumor cell Method has been increasingly becoming the hot spot for the treatment of tumour.The method of the tumour of biological immune treatment at present is more, thin including common CIK Born of the same parents' immunization therapy, DC medications treatment etc., but its therapeutic effect is not notable, and survival is not improved significantly.Separately have With the immunocyte medication that not mutated tumour high-expression albumen stimulates, research has anti tumor immune response, but since its is non-specific Property expression, no doubt with the presence of side reaction, including eye-blurred, Hearing, fash etc..

The essence of biological immune treatment is mainly by body immune system come killing tumor cell, is made wherein directly playing It is killer T cell, and Dendritic Cells (DCs) is antigen presenting cell (APCs), major function is by antigenic information Offer to T cell.It is believed that certain autoimmune responses are since microenvironment tissue damage causes local DC to activate, then It interacts with T cell, so as to cause immune response.Therefore, the ability of DCs initiations t cell response can be used for tumour medication In.The related high protein induced generation DCs of expression of some tumours of external use, and defeated time patient's body, it is relatively special to be used as tumour Induced t cell in APCs.Animal model has confirmed that DC tumour medications reverse the anergy of T cell and cause to connect The anti-tumor effect got off.However, the related height of tumour expresses the DCs of protein induced generation and without stringent specificity, swell Histocyte other than knurl also expresses same albumen, and therefore, side reaction is a problem.

Tumour is the unlimited hyperplasia of cell as a result, and the growth of cell is by gene-determined.There are tumours in human body Gene and the different gene group of two big function of tumor suppressor gene.Tumour is due to the up-regulation of oncogene function, tumour The suppressed result of suppressor function.Various extraneous factors are by gene such as radioactive ray, carcinogenic chemicals, virus etc. Change and carry out induced tumors, the change of gene includes the various DNA damages such as base mutation, base crosslinking, DNA break, DNA missings Wound.Gene therapy is the biomedical treatment based on the inhereditary material for changing people, is by the normal gene of people or has treatment The gene of effect imports human body target cell by certain way, directly against the root of disease --- and abnormal gene is sent out in itself Therapeutic effect is waved, so as to achieve the purpose that treat disease；Gene therapy product enters generates target protein or more again after cell Peptide, so as to play special biological therapy effect.Clinical experiments have proved that the effect of gene therapy, is higher than simple Radiotherapy chemotherapy curative effect Go out several times；When treating non-small cell carcinoma, 60% patient tumors subside completely or partial remission；The effect of to breast cancer is even more height Up to 90%.
