Question

Class II MHC molecules are found on which of the following?
A) all body cells with a nucleus
B) red blood cells
C) granulocytes and microphages
D) lymphocytes and antigen-presenting cells
E) liver cells and macrophages in the spleen

Accepted Answer

Class II MHC molecules are found on lymphocytes and antigen-presenting cells such as macrophages, dendritic cells, and B cells. They present antigens to CD4+ T cells and play a role in adaptive immunity. They are not found on all body cells with a nucleus, red blood cells, granulocytes, or liver cells.
