Effect of probiotic treatment in broiler chicks on intestinal macrophage numbers and phagocytosis
of Salmonella Enteritidis by abdominal exudate cells.
2004) proposed to define the "unhealthy" immune response profile of unfed oysters as displaying low phagocytosis
and a high respiratory burst.
the acute phase reactant, C-reactive protein, which binds to the C-polysaccharide of many bacteria, promoting phagocytosis
Because several aspects of innate immunity are altered in patients with diabetes, namely, depressed polymorphonuclear leukocyte function and altered leukocyte adherence, chemotaxis, and phagocytosis
(Delamaire et al.
Receptor- mediated endocytosis and phagocytosis
by rainbow trout head kidney sinusoidal cells.
If the particle concentration is too high to be removed by the lymphatic system, the macrophages in the vicinity attempt to engulf the wear particles by phagocytosis
The smear was observed under oil immersion objective (X100) of a light microscope (Olympus, Japan) and the percentage phagocytosis
was determined by counting 200-300 stained PMN per slide.
It is believed that the substance helenalin found in the flower heads of the plant stimulates phagocytosis
, the process by which cells clear out waste and repair tissue damage.
The impairment of phagocytosis
leads to severe infections, as can be seen in patients with primary and secondary immunodeficiencies (1-6).
Lyn seems to be a very potent signaling mediator in both epithelial and macrophage cell types and orchestrates many downstream pathways that regulate cytoskeletal changes for effective phagocytosis
and increased expression of pro-inflammatory cytokines.
There are several possible explanations for this negative effect of antioxidants on mortality, one of which is that by eliminating (or reducing) free radicals we are interfering with some of the body's essential defence mechanisms such as apoptosis, phagocytosis
and detoxification which depend on reactive oxygen species.
The pathophysiology of vascular damage in maternal decidual vasculopathy is unknown, but the 2 key findings in the involved vessels in this lesion are well described: (1) atherosis appears to be histiocytic phagocytosis
of damaged endothelial cells of the spiral arteries, and (2) the dense pink fibrinoid necrosis may be some amalgam of the coagulation cascade proteins and intermediate filaments.
