Phagocytes of humans and other animals are called professional or non-professional, depending on how good they are at phagocytosis. The professional phagocytes are neutrophils, monocytes, macrophages, dendritic cells, and mast cells.
Non-professional phagocytes are more limited than professional phagocytes in the type of particles they can take up. This is due to their lack of efficient phagocytic receptors, in particular opsonins âwhich are antibodies and complement attached to invaders by the immune system.hey are called non-professional phagocytes, to emphasize that, in contrast to professional phagocytes, phagocytosis is not their principal function. Fibroblasts, for example, which can phagocytose collagen in the process of remolding scars, will also make some attempt to ingest foreign particles.
