Document Summary
Gram negative bacteria more sensitive to antimicrobial peptides than lysozymes. C3b (opsonin-function to increase phagocytosis (ability of macrophages to do this): phagocytosis: non specific, oxidative burst (enzymes myalloperoxidase, nadh oxidase, another) 3. inflammation and fever mediated by cytokine il1 cells get to the site of infection. Tolerance (tolerate itself but will not tolerate incoming pathogens) T cells (2 categories: helper (activate other cells) and cytotoxic (kill infected cells)) Major histocompatibility complex: mhc1-present antigens from within cells. Mhc2- activate helper tcells (memory cells that stay dormant and effector tcells) which leads to. Dont infect host. A subunit for ab toxin is responsible for (b for binding) modify the target inside host cell (c) Complement (b) is more effective against gram ve bacteria (some ve completely resistant against it; opsonin for +ve and -ve)
