Target Information
Cluster of differentiation 8 (CD8) is a type I transmembrane glycoprotein belonging to the immunoglobulin receptor family. It plays a central role in T cell signal transduction, differentiation, and activation. CD8 is primarily expressed on T cells as a disulfide-linked heterodimer of CD8α and CD8β, functioning as a co-receptor with T cell receptor (TCR) for major histocompatibility complex class I (MHC-I) molecules.
CD8α is essential for MHC-I binding and is also found on subsets of T cells, NK cells, monocytes, and dendritic cells as homodimers. Engagement of MHC-I/peptide complexes on antigen-presenting cells recruits Lck kinase, leading to lymphokine production, motility, and cytotoxic T lymphocyte (CTL) activation. Activated CTLs are critical for pathogen and tumor cell clearance. Differentiation of naive CD8+ T cells into CTLs is enhanced by IL-2, IL-12, and TGF-β1.
