Question

Quizplus · Accepted Answer

Helper T cells play a crucial role in coordinating and regulating the immune response, activating other immune cells such as B cells and cytotoxic T cells. Decrease in helper T cells would impair both the humoral and cell-mediated immune response. Conversely, decrease in cytotoxic T cells (A) would impair only cell-mediated response, decrease in suppressor T cells (C) would lead to overactivation of the immune response, and decrease in B lymphocytes (D) and plasma cells (E) would only impair the humoral immune response.
