'''CD8''' (or '''Cluster of Differentiation 8''') is a T-cell co-receptor.  CD8 binds to class I MHC protein.  CD8 exists as 2 isoforms: α and β.  CD8 forms a dimer of CD8α and CD8β.  The extracellular domain of CD8 has immunoglobulin variable-like conformation.  This domain of CD8α interacts with α3 domain of class I MHC enhancing the binding of the T-cell receptor and the target cell.
