Inducible T-cell costimulator (ICOS) also known as AILIM or CD278 is a member of the CD28 superfamily of proteins. ICOS is a surface receptor protein approximately 60 kDa in mass. This protein is expressed mainly on activated T cells. It does not appear on naive or resting T cells. ICOS plays an important mechanical role in the immune response as its engagement enhances the production of cytokines and supports cell-cell interactions through its binding to the ICOS ligand.
Biological function summary
ICOS plays a critical role in the regulation of immune responses. It acts as a costimulatory signal for T cells supporting their proliferation and differentiation. ICOS helps form part of a complex involving interactions with the ICOS ligand present on antigen-presenting cells. This interaction affects the function and fate of various T cell subsets including T follicular helper cells which are important for antibody production.
Pathways
ICOS is part of the immune signaling pathway. It associates closely with the CD28 signaling pathway enhancing T-cell activation and survival. ICOS interacts with proteins such as the ICOS ligand (ICOSL) on antigen-presenting cells which helps mediate its effects. These pathways are essential in immune system homeostasis and adaptive immune responses where dysfunction can lead to immune-related diseases.
ICOS has implications in conditions such as autoimmune diseases and cancer. Abnormal expression or function of ICOS relates to the development of autoimmune conditions like systemic lupus erythematosus (SLE) where the overactive immune response damages the body's tissues. Additionally ICOS might support tumor progression in certain types of cancers by promoting immune escape. It interacts with regulatory proteins like CTLA-4 and PD-1 in these diseases which are notably involved in immune checkpoint pathways.
