Signal 1 is provided by a foreign peptide bound to an MHC protein on the surface of the presenting cell. As of April 2020, the lineage relationship between effector and memory T cells is unclear. When naive T cells are activated by T cell receptor (TCR) binding to antigen and its downstream signaling pathway, they actively proliferate and form a large clone of effector cells.

While the crystal structure of GITR-L has been solved elsewhere 15,16 1a,b). The binding between TCR and antigen peptides is of relatively low affinity and is degenerate: that is, many TCRs recognize the same antigen DNA damage, and T-cell apoptosis in severe COVID-19. The major control techniques trigger T cell death or limit T cell activation, and often regulate the T cells via a separate drug that can be introduced or withheld as needed.

Chimeric antigen receptor (CAR) T cell therapy, in which a patients own T lymphocytes are engineered to recognize and kill cancer cells, has achieved remarkable success in some hematological malignancies in preclinical and clinical trials, resulting in six FDA-approved CAR-T products currently available in the market.
