Document Summary
Do not bene t the cell that secretes them-interferons diffuse to neighboring cells & stimulate them to produce antiviral proteins-activate nk cells & macrophage (destroy infected host cells) Lymphatic tissues composed of total of lymphocytes and macrophages that populate many harmonium in the soundbox. Immune system of rules fails to react vigorously enough. A group of 30 + proteins that contribute to nonspeci c resistance & speci c immunity -synthesized by liver-circulate blood in inactive kind -activated by pathogen. Accompaniment protein form halo in plasma membrane of target cell causing cytolysis. Very large in fetus (don"t have a strong immune system )-after age fourteen , exponentiation (shoplifting ) begins-in elderly, mostly composed of fatty and brous tissue.
