WebThis means that although B cells ingest and process antigens like normal APC do, they don't interact and activate Naive helper T cells like, for instance, dendritic cells do. They interact with helper T cells that have proliferated and differentiated into effector cells. The B cells just "re-activate", if you will, the effector cells. Web2 days ago · Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells. arrow_forward.
