T Cell Receptor Signaling Pathway KEGGNCIt concept
Preferred Label : T Cell Receptor Signaling Pathway KEGG;
NCIt synonyms : TCR Signaling Pathway;
NCIt related terms : T cell receptor signaling pathway;
Alternative definition : KEGG: Activation of T lymphocytes is a key event for an efficient response of the
immune system. It requires the involvement of the T-cell receptor (TCR) as well as
costimulatory molecules such as CD28. Engagement of these receptors through the interaction
with a foreign antigen associated with major histocompatibility complex molecules
and CD28 counter-receptors B7.1/B7.2, respectively, results in a series of signaling
cascades. These cascades comprise an array of protein-tyrosine kinases, phosphatases,
GTP-binding proteins and adaptor proteins that regulate generic and specialised functions,
leading to T-cell proliferation, cytokine production and differentiation into effector
cells.;
