Figure 1 Antibody structure. Lesson Explainer Specific Immune Response Antibodies Nagwa When an antigen is detected by a macrophage as describe above under phagocytosis this causes the T-cells to become activated. . You develop this when your body is exposed to microbes or chemicals released by microbes. The adaptive immune system works because the immune cells responsible for it are each able to recognize and respond to one specific antigen or a few very similar ones. 3 rows The hallmark of the adaptive immune system is clonal expansion of lymphocytes.
