Document Summary
T cells, increased expression of accessory adhesion molecules. Toxoid - toxin with no toxic effect, does not make the patient sick but can still stimulate antibody response. Remove the series of dna hat makes infection from the toxin, must have antibodies made to other parts than the inactive part so when an active toxin comes in, the antibodies can still be recognized. Some memory cells don"t last very long in the body. Booster shots are needed to make sure re-infection doesnt occur. Antigen attaches to t cell - which then induces b cell. Stimulate a wide variety of b cells independently of the speci c antigen receptors. Give rise to low-af nity igm rather than igg ab response and do not induce memory response. Most ags stimulate b cells only if assisted by t-lymphocytes helper (th) Binding of th presented ag on b-cell surface, results in cytokine production to activate b cell which undergoes clonal expansion.
