Background Information
Cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) is a co-inhibitory receptor that plays a crucial role in regulating T-cell activation and maintaining immune tolerance and delivers inhibitory signals that suppress T-cell responses, thereby preventing autoimmune diseases. It is expressed on activated T cells and regulatory T cells (Tregs), which mediates its inhibitory function by competing with CD28 for binding to CD80/CD86, depleting these ligands from antigen-presenting cells (APCs) and dendritic cells (DCs), and delivering inhibitory signals via its intracellular tail. CTLA-4 exists in two forms: membrane-bound CTLA-4 (mCTLA-4) and soluble CTLA-4 (sCTLA-4). mCTLA-4 is a transmembrane protein localized on the surface of T cells and Tregs, where it interacts with CD80 and CD86 on APCs. sCTLA-4 lacks the transmembrane domain and is released into the extracellular environment, where it can modulate immune responses.
