Target Information
Cluster of differentiation 8 (CD8) is a type I transmembrane glycoprotein belonging to the immunoglobulin family of receptors. It plays a critical role in signal transduction, T cell differentiation, and activation. CD8 is predominantly expressed on T cells as a disulfide-linked heterodimer of CD8α and CD8β, functioning as a co-receptor with the T cell receptor (TCR) for MHC class I molecules. The CD8α chain is essential for MHC-I binding and is also expressed as a homodimer on subsets of T cells, NK cells, monocytes, and dendritic cells. Engagement of MHC-I/peptide complexes by CD8 triggers recruitment of Lck kinase, leading to lymphokine production, cell motility, and activation of cytotoxic T lymphocytes (CTLs). Activated CTLs are vital for pathogen and tumor cell clearance, and their differentiation is enhanced by IL-2, IL-12, and TGF-β1.
