T cell receptor signaling and cell immunotherapy

As the major sensor of adaptive immune system, T cell receptor(TCR) can recognize diverse antigens and initiate specific immune responses against invading pathogens and cancer cells. Understanding the mechanisms of TCR signaling has led to the development of engineered T cell therapies, which have extensive applications in the treatment of diseases such as cancer, infection and autoimmunity. Here, we review the current understanding of antigen-induced TCR signaling and discuss its applications in T cell therapies.
