Definitions
- the present invention relates to mesothelin-specific chimeric antigen receptors and T cells expressing the same.
- T cells are cells that play an important role in mediating adaptive immunity. T cells are activated through stimulating receptors (T cell receptor, TCR), co-stimulatory molecules, and cytokines. In addition, TCR of T cells causes an immune response through an antigen-associated MHC molecule (major histocompatibility complex, MHC molecules), and cancer cells suppress the expression of MHC molecules as a mechanism to avoid the immune response.
