 肿瘤抗原肽是新一类肿瘤标志物。肿瘤抗原在细胞体内被分解后

产生的小分子多肽,和MHC I结合形成MHC I-抗原肽复合物后,

 表达在癌细胞的表面。该复合物能够被CD8 T细胞识别,因此可以

被利用作为癌细胞的靶分子,可用于诊断和治疗的各个方面,因

鉴定癌细胞肿瘤抗原肽具有重要的意义。我们发展出了一套

 合了免疫-生物化学化/生物物理-生物信息学方法来鉴定肿抗原

 肽的技术平台。细胞学试验表明,鉴定出来的抗原肽能诱导出高度

特异的肿瘤杀伤作用。

Tumor antigen peptide identification platform

    Tumor antigen peptide is a new class of tumor markers. Tumor antigens

 are decomposed in the cell to generate peptides, which bind to MHC-1 to

 form MHC-1/antigen peptide complexes, and are displayed on cancer cell 

surface. The complexes can be recognized by corresponding CD8 T cells,

 and therefore can be used as targets for diagnosis and treatment. Identification 

of cancer cell tumor antigen peptides is, therefore, of great importance. We

 have developed a technical platform that integrates immune-biochemical /

 biophysical-bioinformatics methods to identify tumor antigen peptides. Our 

studies on cultured cells have shown that the identified antigenic peptides

 can induce a highly specific tumor killing effect.

 

Technical features and highlights

1.    Patented technology involved (patent no. 201310439062.2);

2.    The peptides thus obtained are those naturally processed by tumor 

celss, therefore authantic and useful;

3.    The peptide(s) can be used to stimulate tumor specifc CD8 T cell for

 cell immunotherapy;

4.    The peptide(s) origing protein(s) can be the tumor marker(s),  of potential

 use in diagnoisis;

5.    Useful in anti-tumor peptide vaccine development.
