Abstract

The invention provides a polypeptide reagent for activating human immune cells. The polypeptide reagent comprises 6-aminopurine, folic acid, glycyl-L-glutamine, L-glutathione, thymopentin, Pp25 and Pp21, wherein Pp25 and Pp21 are prepared by a solid-phase polypeptide synthesis technology.

Description

technical field [0001] The invention relates to the technical field of tumor immunology, in particular to a polypeptide reagent for activating human immune cells. Background technique [0002] Cancer is a major disease that threatens human life, and biological immunology is considered to be the only possible way to completely cure cancer. [0003] At present, the mainstream idea of ​​tumor immunology research is to search for tumor-specific antigens and try to sensitize immune cells with tumor-specific antigens, so as to rely on immune cells to kill tumor cells and achieve the purpose of curing cancer. ——This idea is similar to microbial vaccines and snake venom antiserum: both microbial vaccines and snake venom antiserum rely on the preparation of specific antigens to sensitize the immune system to obtain reliable disease resistance. In contrast, tumor-specific antigens are far from successful, and humans have not even been able to confirm whether tumor-specific antigens a...
