Expert Solution

Step 1

In molecular biology, CD4 is a glycoprotein that acts as a co-receptor for the T-cell receptor. Immune cells such T helper cells, monocytes, macrophages, and dendritic cells all have CD4 on their surface.

A transmembrane glycoprotein called CD8 functions as the T-cell receptor's co-receptor. In addition to the TCR, the CD8 co-receptor participates in T cell signalling and facilitates contacts between cytotoxic T cells and antigens.
