Solution:

The abbreviation of CD stands for cluster of differentiation; a designation which refers to the proteins found on the surface of cells. CD8 markers are a group of transmembrane glycoproteins which act as co-receptors for the T-cell receptor. Similar to the T-cell receptor, CD8 markers bind to the major histocompatibility complex (MHC) molecule, specifically to class I MHC proteins. Predominantly, the CD8 markers or co-receptors are expressed on the surface of cytotoxic T-cells.
