First step of phagocytosis
WebAug 20, 2024 · Detection of the target particles is the first step of phagocytosis. 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. 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.
