What is TCR-T cell therapy
TCR-T cell therapy, short for T cell receptor-engineered T cells, is based on gene editing technology to specifically recognize tumor antigen T cell receptors（TCR ）gene, be introduced into the patient's own T cells to make them express exogenous TCR, so as to recognize and attack tumor cells and achieve the purpose of tumor treatment.
Quality control of TCR-T cell therapy technology
At present, no relevant guidielines for TCR-T cell products have been released at home and abroad, and TCR-T cell products have similarities with CAR T cell products in terms of production raw materials, production technology, process control, accessories, packaging containers, stability, etc., so the relevant guidelines and considerations can be referred to in quality evaluation. It is mainly divided into safety, purity, efficacy and uniformity etc.
