(A) Sensitized helper $T$-cells (also known as $CD4^+$ $T$-cells) play a crucial role in the immune response by coordinating other immune cells.Upon activation by antigens presented by antigen-presenting cells,these cells secrete signaling proteins known as lymphokines.Lymphokines act as chemical messengers that stimulate the proliferation and activation of $B$-cells,cytotoxic $T$-cells,and macrophages,thereby enhancing the overall immune response.Lysozyme is an enzyme found in secretions like tears and saliva,perforins are produced by cytotoxic $T$-cells and natural killer cells to destroy target cells,and lysin is a general term for substances that cause lysis.
