Question

Quizplus · Accepted Answer

Class-2 MHC molecules are expressed on antigen-presenting cells like macrophages, dendritic cells, and B lymphocytes, which present antigens to CD4+ T cells. Mature red blood cells lack nuclei and other organelles such as MHC molecules, as they undergo enucleation during development. Hence, class-2 MHC molecules are not found on mature red blood cells.
