Phagocytosis: A Fundamental Process in Immunity - Hindawi

WebThe first step in phagocytosis is the detection of the particle by phagocytes. This, as mentioned before, is accomplished by specialized receptors on the cell membrane. Foreign particles, such as microbial pathogens, can be recognized directly by receptors that bind molecules not found in higher organisms, or indirectly through opsonins. WebPhagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it.

In 1903, Wright and Douglas discovered that the uptake of staphylococci by human leukocytes is enhanced by serum ( Wright et al., 1989 ). They concluded that blood fluids have an opsonic power that modifies bacteria to be ingested by the leukocytes.
