I should be interestin that the macrophage is the oldest know immune cell. Not only will this guy do some killing. He will clean up behind himself. He will also clean up behind you.
Phagocytosis is mediated by macrophages and polymorphonuclear leucocytes.
This is the movement of cells up a gradient of chemotactic factors. It may be directly induced by a substance such as C5a, produced as a result of complement activation. Leukotrienes, produced by the metabolism of mast cell arachidonic acid, are also chemotactic. This works reasonably well for whole bacteria or viruses, but less so for proteins or encapsulated bacteria. The phagosome moves deeper into the cell, and fuses with a lysosome, forming a phago-lysosome.
