Document Summary
Describe the major differences between innate and adaptive immunity. Bridge to adaptive immunity (are effector cells of adaptive immunity) Uses macrophages, neutrophils, dcs, granulocytes, mast cells, nk, ilc, nkt, B1, gamma/delta t, cd4 t(reg) cells; epithelial cells. C-reactive proteins, lbp, scd14, mbl, complement and ig receptors, mannose and scavenger receptors, cd14, tlrs, nod. Attacks small extracellular (bacteria) and large extracellular (protozoa, fungi) and intracellular pathogens (virus bacteria, yeast, protozoa) Cd8 tc, b cells, antibodies excluding t- lymphocyte antibodies. Attacks intracellular pathogens (virus bacteria, yeast, protozoa) and large size extracellular pathogens (protozoa, fungi) Both release cytokines: many highly virulent human microbial pathogens such as bacillus anthrax, yersinia pestis, and. Streptococcus pyogenes have a natural reservoir and/or an ecological niche outside of humans. They can often live and reproduce well outside of the human hosts. The benefit for bacteria that cause such devastating diseases in humans is that it allows for the propagation and proliferation of the organism.
