T Lymphocyte Surface Proteins (None)

T lymphocyte surface proteins are a group of molecules expressed on the plasma membrane of T cells, central to adaptive immunity. The T cell receptor (TCR) is the most defining, recognizing antigens presented by MHC molecules. Other key proteins include CD3, CD4, and CD8, which play roles in signal transduction and co-receptor functions. These proteins are critical for antigen recognition, T cell activation, and effector functions, making them important therapeutic targets in immunotherapy and transplant rejection prevention.
