Also, Tissue sampling for H5N1 found a notable absence of dendritic cells whose job it is to phagocytize
protein components from the virus and present these to T cells, either locally or at the lymph nodes that drain the lungs.
The source of most of these compounds is likely to be macrophages that infiltrate the corpus luteum during luteolysis to degrade the extracellular matrix and phagocytize
the byproducts of tissue degeneration.
Microglia play a central role in mediating CNS inflammatory processes and as the only resident brain immune system cells, activated microglia can proliferate, migrate to sites of injury, present antigen, phagocytize
, secrete proinflammatory cytokines and cytotoxins, and undergo a nicotinamide adenosine dinucleotide phosphate (NADPH)-mediated respiratory burst producing cytotoxic reactive oxygen and nitrogen species.
Circulating eosinophilic granulocytes, however, are able to bind and phagocytize
non-self substances in vitro.
Neutrophils are phagocytic--they phagocytize
(eat or engulf) bacteria and debris.
Not only do macrophages phagocytize
debris and foreign bodies, they also recruit other immune cells.
When discovery occurs, natural killer (NK) cells are rallied by the now unimpeded immune system to move in and phagocytize
the obvious dysfunctioning anaerobic cell.
Although macrophages are not pathologically noticeable in normal gut mucosa, they can be identified when they phagocytize
and accumulate exogenous or endogenous substances .
The macrophages phagocytize
the oxidized LDLs and are transformed into foam cells.
Treated and untreated control cells were assayed for their ability to phagocytize
protein-coated latex particles (Sakashita et al., 1991).
(2001) reported that mast cells could phagocytize
diverse particles, take up antigens, and express a number of receptors, particularly MHC class I and II antigens, ICAM-1 and -3, CD43, CD80, CD86 and CD40L, and allow them to interact with T and B lymphocytes.
The K1 capsule is a virulence factor, acting as a shield to the organism by decreasing the ability of antibodies to bind to the bacteria and inhibiting the ability of white blood cells to phagocytize
