Question

Quizplus · Accepted Answer

Natural killer cells are able to secrete perforins that bore holes in the cell membrane of enemy cells, allowing the entry of granzymes that induce apoptosis. Interferons are signaling proteins that help to fight viral infections, interleukins are signaling molecules involved in the immune response, antibodies target specific antigens, and opsonization is the process in which particles are targeted for phagocytosis by binding to specific receptors on phagocytes.
