                Target Information

                ICOS (CD278) encodes a protein that is a member of the CD28 and CTLA-4 cell-surface receptor family. It functions as a homodimer and has a crucial role in cell-cell signaling, immune responses, and the regulation of cell proliferation. ICOS has been linked to various disorders, including Immunodeficiency, Common Variable, 1 and Common Variable Immunodeficiency.
