Study Notes
Humoral Immune Response
- Involves B cells recognizing antigens in the lymph or blood
- B cells are activated when they recognize antigens through their surface-bound antigen receptors
Activation of B Cells
- Antigen recognition by B cells stimulates them to proliferate and produce plasma cells
- Cytokines, in particular IL-4 and IL-5, stimulate B cells to proliferate and differentiate into plasma cells
Plasma Cells
- Bear antigen receptors with identical specificity as the activated B cells
- Produce large amounts of antibody, which is released into the bloodstream
Immune Memory
- B cells produce antibodies to provide future immunity
- Memory B cells remain in the body, providing long-term immunity against specific antigens
Immune Recognition
- The immune system recognizes two groups of foreign substances: haptens, which require a carrier protein to stimulate an immune response, and immunogens, which can stimulate an immune response on their own
Cell-Mediated Immune Response
- Involves virus-infected and tumor cells actively synthesizing foreign proteins
- Recognized by T cells, which then activate other immune cells to eliminate the infected cells
