In a modern immunological perspective, it may be asserted that the phagocytic cell should not be considered as the %26quot;serfdom%26quot;, but rather the pivot of the immune system. Indeed, the invertebrate immunocyte as well as the vertebrate macrophage play a central role in immunity, inflammation and stress response. The evolutionary conserved immune-neuroendocrine effector system have remained of fundamental importance in defense against pathogens, and its efficiency increased through synergy with the new, clonotipical recognition repertoire in vertebrates.
