Target Information
Cluster of differentiation 8 (CD8) is a type I transmembrane glycoprotein of the immunoglobulin receptor family that plays a key role in T cell signal transduction, differentiation, and activation. CD8 is mainly 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. In contrast, CD4 acts as a co-receptor for MHC class II. CD8α is essential for MHC-I binding and is also found on subsets of T cells, NK cells, monocytes, and dendritic cells as CD8α homodimers. Binding of MHC-I/peptide complexes on antigen-presenting cells (APCs) recruits Lck kinase, leading to lymphokine production, motility, and cytotoxic T lymphocyte (CTL) activation. Activated CTLs are crucial for eliminating pathogens and tumor cells. Differentiation of naïve CD8+ T cells into CTLs is enhanced by IL-2, IL-12, and TGF-β1.
