Document Summary
Helper t cells" = release respiratory burst which kill pathogens resistant to ly enzymes: release free radicals, oxidizing chemicals. Antimicrobial defenses: interferon = small cytokines produced by leukocytes; immune modulating pros, interfere with viral replication, produce pros that block viral reproduction and degrade viral. Intracellular pathogens (effectors: virus-infected cells and cancer cells: + selection capable of recognizing mhc restriction (failure to recognize = cell suicide) Selection must not recognize self-antigens; failure to recognize = survival: maturation. Vaccines: priming the system or creating a memory , if/when we get infected secondary response. Antibody structure (t or y antibody monomer), variable & constant regions. Tips of the y are the antigen binding sites. Igm (pentamer) first to appear in large numbers in a new response; causes agglutination. Igg (monomer) most common type in plasma most of the time, crosses placental barrier. Ige (monomer) defense against parasitic worms; causes allergic responses.
