摘要: The molecular basis for discrimination between self and non-self, a crucial distinction at all levels of organization living matter, remains one the intriguing puzzles immunobiology. In order to survive, animals have evolved some kind response recognize eliminate non-self without destroying self. first cell appear that was specialized use in host defense mononuclear phagocytic cell. amoebocytes, coelomocytes, or hemocytes invertebrates are believed be ancestors monocyte/macrophage system found higher vertebrates man. Phagocytosis is fundamental attribute many cells, particularly important vast number invertebrates, since process related nutrition excretion as well defense[25].
