TH Cells Express a ________ Protein Coreceptor

Question

TH cells express a ________ protein coreceptor.
A) CD4
B) CD8
C) CD12
D) T cell receptin

Accepted Answer

TH cells express the CD4 protein coreceptor, which interacts with the MHC class II molecule on the surface of antigen-presenting cells. CD8 is expressed on cytotoxic T cells, CD12 is not a known protein receptor, and T cell receptor is the antigen-specific receptor on both CD4 and CD8 T cells.
