Chimeric Antigen Receptor (CAR) T Cell Therapy Development

Chimeric antigen receptor (CAR) T cell therapy is a rapidly evolving and promising immunotherapy. This therapy has shown tremendous success in treating certain types of rare diseases. As an innovative company specializing in the development of therapies for rare diseases, our company is dedicated to providing clients with chimeric antigen receptor (CAR) T cell therapy development services.

Introduction to Chimeric Antigen Receptor (CAR) T Cell

T cells, as an essential component of immune system, play a crucial role in combating external infections and diseases. In recent years, researchers have found that T cells can be artificially transformed into chimeric antigen receptor (CAR) T cells to enhance their anti-cancer efficiency. CAR-T cell involves genetically modifying a person's own T cells to express a synthetic receptor (the CAR) that targets specific antigens on cancer cells. CAR-T technology has directly altered the way T cells recognize antigens, bypassing MHC restrictions, possessing high specificity, and preventing T cell immune evasion. CAR is designed to express recombinant or chimeric antigen receptors to specific target on cancer cells, by inducing immune response to reduce cancer cell proliferation and cause cell death.

Chimeric antigen receptor (CAR) structure primarily consists of three components:

  • Target receptor segments
  • Membrane-permeable regions
  • Intracellular region

Based on different intracellular regions, CAR-T cells can be divided into first, second, third and fourth generations. Up to now, fourth-generation CAR-T cells perform better in the tumor microenvironment (TME) than previous generations because they possess stronger ability to destroy cancer cells.

Chimeric Antigen Receptor (CAR) T Cell Therapy

CAR-T cells possess potent ability to target and destroy tumors, and have demonstrated significant anti-tumor activity in various hematologic malignancies such as hemophilia. Diverse structures of CARs enable them potentially feasible for the therapy development of multiple rare diseases.
