(10) Human milk contains active macrophages and neutrophils, which phagocytize
bacteria-IgA complexes and activated T cells.
"There's a complex interaction that occurs between the melanocytes and the keratinocytes, where they phagocytize
the ends and take up the melanosomes," said Dr.
Endodermal epithelial cells of the first type of hydra strains do not phagocytize
as many chlorococci and do not allow chlorococci to stay in their cytoplasm, probably through digestion (e.g., vulgaris group: K5, K6; oligactis group: L5, G7).
In sepsis, macrophages phagocytize
pathogenic bacteria and secrete large amounts of cytokines.
In addition to their ability to phagocytize
potentially harmful antigens, neutrophils can activate potent antimicrobial defense mechanisms such as the release of reactive oxygen species (ROS) and extracellular neutrophilic DNA traps (NETs) [21-23].
In bivalve molluscs, hemocytic activity is involved in several physiological functions; in the case of the immune response, these cells play a key role because they detect, encapsulate, and phagocytize
foreign agents, which are subsequently removed (main cell defense mechanism) (Cima et al.
Neutrophils may therefore be needed to phagocytize
sulphonamide antibodies-coated red blood cells leading to their ultimate extravascular destruction.
In the inflammatory stage, neutrophils phagocytize
cellular debris and macrophages remove dead tissue and stimulate the production of cytokines that activate satellite cells in the injury site (Fielding et al., 1993; Beicastro et al., 1996; Jarvinen et al., 2000; Kannus et al., 2003).
apoptotic neutrophils to prevent further tissue damage, thus resulting in resolution of wound inflammation and promoting wound healing [20,21].
RPE cells envelop and phagocytize
outer parts of photoreceptors, deliver nutrient for photoreceptors, but also serve as a barrier that protects photoreceptors from unfavorable factors from the choroid.
In peripheral organs such the skin, when an infection occurs, the Antigen Presenting Cells (APCs), mostly dendritic cells, phagocytize
the bacterium and present the antigens to lymphocytes located in the lymph node near the infection site, inducing the development of an adaptive response against the pathogen.
