Inducible T-cell costimulator is an immune checkpoint protein that in humans is encoded by the ICOS gene. CD278 or ICOS (I nducible T-cell COS timulator) is a CD28-superfamily costimulatory molecule that is expressed on activated T cells. It is thought to be important for T h 2 cells in particular.

Human ICOS deficiency abrogates the germinal center reaction and provides a monogenic cause of CVID ICOS acts as a costimulatory signal for T-cell proliferation and cytokine secretion, Journal of immunology (Baltimore, Md. : 1950) 2004 Nov 1;173(9):5880-7 Abstract The costimulatory protein ICOS is inducibly expressed on activated T cells. Previous results have shown that ICOS–/– mice are defective in germinal Mar 31, 2014 We now show that concomitant CTLA-4 blockade and ICOS of off-the-shelf ICOS agonist that can enhance T cell immunity against any target Apr 29, 2020 Thus, we show that ICOS signaling in T cells promotes an effective may enhance protective immunity to blood-stage Plasmodium infection.

CD278 or ICOS (I nducible T-cell COS timulator) is a CD28-superfamily costimulatory molecule that is expressed on activated T cells. It is thought to be important for T h 2 cells in particular. Department of Microbiology and Immunology, University of Arkansas for Medical Sciences, Little Rock, AR, USA. Over the last 15 years, the inducible T cell co-stimulator (ICOS) has been implicated in various immune outcomes, including the induction and regulation of Th1, Th2, and Th17 immunity. In addition to its role in directing effector T cell ICOS-L is activated in several types of cancers to maintain immunosuppressive CD4+ T cell subsets, such as regulatory T cells (Tregs). ICOS-L over-expression is associated with tumour progression and poor overall survival. Introduction.

Methods in Molecular Biology, vol 1393. The differentiation of Tfh cells is a multi-step process that depends upon the co-receptor ICOS and the activation of phosphoinositide-3 kinase leading to the expression of key Tfh cell genes. We report that ICOS signaling inactivates the transcription factor FOXO1, and a Foxo1 genetic deletion allowed for generation of Tfh cells with reduced dependence on ICOS ligand. ICON's immuno-oncology experience in all development phases over the past five years includes indications in leukemia, lymphoma, NSCLC, pancreatic cancer and solid tumours. Successfully implementing the required trial design strategies will require substantial expertise that many sponsors do not have in house.

The inducible costimulatory molecule (ICOS) is expressed on activated T cells and participates in a variety of important immunoregulatory functions. Download this antibody, disease, immune system, immunology icon in outline style from the Education, school & learning category. ICOS is a key costimulatory receptor facilitating differentiation and function of follicular helper T cells and inflammatory T cells. Rheumatoid arthritis patients were shown to have elevated levels of ICOS + T cells in the synovial fluid, suggesting a potential role of ICOS-mediated T cell costimulation in autoimmune joint inflammation. ICOS (Inducible T Cell Costimulator) is a Protein Coding gene.
