Document Summary
Microbiology + immunology cell biology of the specific (acquired) immune system: Adaptive/acquired immunity: not present from birth, learns from invading organisms, sophisticated, highly specific recognition, specific memory, slower response (days), activated in immune organs the peripheral (secondary) organs. Induced by exposure to a particular infection: shows a high degree of specificity, exhibits memory" memory cells, requires an innate immune response to have taken place in order to be stimulated. Transferred with serum (blood, isf, tissue fluid) antibody injections, e. g. antivenom. Directed against free antigen (extracellular pathogens and/or components) Mediated by antibodies secreted by b lymphocytes (b cells) Directed against cell-associated antigens (intracellular pathogens) that have breached the cell surface. Mediated by t lymphocytes (t cells: n. b. the effector cells of t and b lymphocytes have lots of rer and golgi, producing a massive turnover of antibodies which can then be secreted in golgi vesicles.
