Document Summary
Innate immune system generalized immune response (those antibodies attack any foreign cells) T helper cells, t suppressor cells, cytotoxic killer cells. Cell-mediated immunity (causes other cells to get rid of it) Activates and proliferates cytotoxic killer cells attack and destroy infectious agent. Antibody-mediated immunity (same as cell med except using antibodies) Macrophage t helper cell collaboration (help in eliminating threat) T helper cells stimulate b cell proliferation. B cells generate antibodies bind to specific infectious agent infectious agent is immobilized and targeted for destruction. Error in identification of infectious agent immune rxn to a innocuous compound. Autoimmune disease thinking there"s a bad guy inside you and attacks you from the inside. Ex: juvenile diabetes attacking pancreatic cells. Stress response impacts immune system activate hpac result in releasing glucocorticoid. Onset of stressor (phase a) (increase immune syst functioning) Innate immunity enhanced we see an increase of inflammation (it gets red and puffy, activating innate immune system)
