Background

Inducible T-cell costimulator (CD278/ICOS) is a ~22 kDa protein. Stimulatory receptor expressed in activated or antigen-experienced T-cells that plays an important role in the immune response. Upon binding to its ligand ICOSL expressed on antigen presenting cells (APCs), delivers costimulatory signals that enhances all basic T-cell responses to a foreign antigen, namely proliferation, secretion of lymphokines including IL10, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B-cells. Also acts as a costimulatory receptor critical for the differentiation of T follicular regulatory cells upon immune challenges such as viral infection. Mechanistically, potentiates TCR-induced calcium flux by augmenting PLCG1 activation and actin remodeling. In addition, activates PI3K signaling pathways independently of calcium flux.
