Target Information

Cluster of differentiation 8 (CD8) is a type I transmembrane glycoprotein of the immunoglobulin family that plays a key role in T cell signal transduction, 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 T cell receptor (TCR) for MHC class I molecules.
CD8 is also present on subsets of T cells, NK cells, monocytes, and dendritic cells as CD8α homodimers.
Engagement of MHC-I/peptide complexes triggers recruitment of Lck kinase, leading to cytokine production, motility, and cytotoxic T lymphocyte (CTL) activation.
Activated CTLs are essential for pathogen and tumor cell clearance. Differentiation of naive CD8+ T cells into CTLs is enhanced by IL-2, IL-12, and TGF-β1.
