Neoantigen polypeptide vaccine service for tumors

At present, the most important treatment methods for tumor are surgery, radiotherapy, chemotherapy and targeted therapy, but these treatment methods have different limitations, the overall treatment effect is poor, and the long-term survival rate of patients is low.

Neoantigens are specific antigens produced by genetic mutations in cancer cells that activate T cells to produce an immune response, thereby inhibiting tumor growth. Because T cells that can recognize neoantigens in the body are relatively rare, and tumor cells escape the killing of specific T cells through immune escape mechanism, people can synthesize these mutated peptides through synthetic technology in vitro, and then inject them into patients to stimulate a large number of T cells that can recognize these neoantigens in the body. Thus, the purpose of specifically killing tumor cells carrying such neoantigens is achieved, and the occurrence of side effects is avoided.
