Preferred Label : T Cell Receptor Signaling Pathway BioCarta;
NCIt related terms : T Cell Receptor Signaling Pathway;
Alternative definition : BIOCARTA: The T Cell Receptor plays a key role in the immune system. The specificity
of the receptor is governed by the binding site formed from the mature alpha and beta
chains or gamma and delta chains in gamma/delta T Cells. It is the ability of this
receptor to bind a complex of foreign peptide in the groove of an MHC molecule that
leads to T cell activation. Upon activation the T cell can assist in activating other
cells or carry out cytolytic attacks depending on the particular T cell type. The
CD3 complex and CD4 (Th cells) or CD8 (Tc cells) work to transmit the activation signal
to the T cell's transcriptional machinery upon engagement of the receptor. (This definition
