T-cell receptor
From Proteopedia
Contents |
Function
T-cell receptors (TCR) reside on the surface of T lymphocytes. TCR recognizes antigens bound to major histocompatibility complex (MHC) molecules. The binding of TCR to the antigen-MHC activates the T lymphocytes[1]. TCR is a heterodimer of α+β subunits and ca. 5% the T cells have a γ+δ subumits. TCR NKT reside in Natural Killer T-cells. For more details see SP3.4-TCR-HLA-DQ8-∝-1-gliadin_complex.
Relevance
Genes encoding antigen-specific receptors into T cells can redirect their functional activity against targets including virally infected or cancer cells[2]. This technique is currently developed by several biotechnology companies and implemented in therapy.
