Explanation:
- Immunity is typically divided into two categories- innate and adaptive.
- Innate immunity is present since birth and consist of many factors that are relatively non-specific.
- Adaptive immunity is also known as specific or acquired immunity, is capable of recognizing and selectively eliminating specific foreign antigen.
- Adaptive immunity displays four characteristic features; Antigen specificity, Immunologic memory, Diversity, Self or non-self recognition.
- There are two branches of acquired immunity, which involve different sets of participants and different purposes but one common aim: to eliminate the antigen.
- One arm of adaptive immune response is mediated by B-Cells and circulating antibodies. This is referred to as humoral immunity.
- The other arm of adaptive immune response is mediated by T-cells, which do not synthesize antibodies but release cytokines that affect other cells.
- T-cell receptors do not form antibodies but perform various effector functions when antigen presenting cells bring antigen into the secondary lymphoid organ.
- T-cells are of two types ; T- helper cell and T-cytotoxic cells.
Answer:
T cells identify pathogens based on antigens on the surface of pathogens. The T cells then multiply and stimulate B cells to produce antibodies. The antibodies attach to the antigens, making the pathogens a target for phagocytes.
