Question

Helper T cells, also known as CD4+ T cells, play a crucial role in regulating the immune response by activating and coordinating other immune cells such as B cells and cytotoxic T cells. They recognize antigen presented on MHC class II molecules and release cytokines that drive immune responses. CD8 cells, also known as cytotoxic T cells, directly kill infected or abnormal cells but do not play a regulatory role in the same way as helper T cells. MHC molecules are important for antigen presentation but do not regulate the immune response on their own.
