Question

Quizplus · Accepted Answer

Only antigen-presenting cells produce MHC class II molecules, which present antigen to helper T cells and activate them. MHC class I molecules, on the other hand, present antigen to cytotoxic T cells and are produced by all nucleated cells in the body. Antigen-presenting cells, such as dendritic cells, macrophages, and B cells, do not produce antibodies themselves but rather present antigen to activate other immune cells that can produce antibodies.
