T-Lymphocyte Activation Antigen CD86 / B7-2 (CD86) Antibody (APC)

Background

CD86, also known as B7-2, is a transmembrane glycoprotein that plays a crucial role in the costimulatory signaling necessary for T-cell activation and immune response. It is a member of the immunoglobulin (Ig) superfamily and is encoded by the CD86 gene located on chromosome 3q21. CD86 is primarily expressed on antigen-presenting cells (APCs) such as dendritic cells, macrophages, and B cells. The interaction of CD86 with its receptors, CD28 and CTLA-4 (CD152), on T cells is vital for regulating immune responses, influencing both the activation and inhibition of T cells.
