Material Safety Data Sheet (MSDS)

Inducible T-cell Costimulator (ICOS) belongs to the CD28 and CTLA-4 family of cell surface receptors, an important family in the regulation of the immune system. It is a homodimer, playing a key role in cell-cell communication and immune response. ICOS is an activation dependant, T-cell specific cell surface molecule; it enhances all basic T-cell responses to foreign antigens, including proliferation, secretion of lymphokines and uptake regulation of molecules that mediate cell-cell communication. This makes ICOS essential for efficient interaction of T and B- cells, required for an effective antigen-specific immune response and for the normal immune response of antibodies to T-cell dependant antigens.
Standard immune responses are normally targeted against microbial pathogens, rather than self-cells. Overexpression of ICOS due to disfunctions in in signalling pathways preventing ligand interactions can increase autoimmunity. ICOS-ICOS-ligand cell contact is necessary for not only enhancement of immune response, but for immune response to occur normally and without autoimmunity.
