Unformatted text preview: Phagocytosis of Pathogen-Tissue damage + microbes Cytokines released then phagocytosis -Histamine dilates brings in clotting proteins.-Heparin so WBC doesn’t clot in capillary. -Defensive protein (opsonins) mark the mibrobe and proliferate and WBC attack the protein marked ( by dipedisis) Globular protein : Makes interferon A,B,G, Gamma (Killer Cells) made by lymphocytes attaches to infected cell prevents replication. Interferon prevents the spread of virus. A,B secreated by virus infected cell when infected release A, B which binds to healthy cells more relealient to virus. G made from active Natural killer and T cells. Killer Cells : Attack virus w/o regognizing it -perforin, part of nonspecific immune response. Complement system : 30 protein on surface of bacteria create Major attack complex. Attaches to antibodies on bacteria or carbohydrate of cell wall of bacteria. Creates a pore water seeps in and lyses the cell....
