2. However, after opsonization, about seven times more bacteria were located intracellularly, indicating that antibodies promoted phagocytosis. (Web site)

Immunoglobulin

1. The spleen has an active role in phagocytosis and in the production of immunoglobulin M (IgM) antibodies and complement.

Organism

1. The organism inhibits many leukocyte functions, including chemotaxis, phagocytosis and respiratory burst and impairs NK cell killing. (Web site)

Pneumocystis

1. Specific immunoglobulin can facilitate clearance of Pneumocystis, presumably by opsonizing the organisms and targeting them for phagocytosis and killing.
2. Phagocytosis of Pneumocystis by alveolar macrophages involves recognition using various cell surface receptors, including mannose and dectin-1 (38, 111). (Web site)

Echinacea

1. When echinacea was stopped a residual stimulating effect lasted about two days as phagocytosis returned to normal. (Web site)

Platelets

1. The coating of platelets with IgG renders them susceptible to opsonization and phagocytosis by splenic macrophages.

Leukocytes

1. Extracellular bacteria typically produce a polysaccharide capsule that allows them to resist complement-mediated lysis and phagocytosis by leukocytes. (Web site)

Capsule

1. The capsule of the organism renders it resistant to phagocytosis. (Web site)
2. Kozel, TR, Gotschlich, EC. The capsule of Cryptococcus neoformans passively inhibits phagocytosis of the yeast by macrophages.
3. The capsule is associated with virulent strains of bacteria and protects the bacterium from phagocytosis. (Web site)

Cells

1. Although the bacteria are opsonised by proteins in serum, the capsule and slime layer protect the cells against phagocytosis. (Web site)

Essential Role

1. Neutrophils play an essential role in fighting bacterial infections by surrounding and destroying invading bacteria (phagocytosis).
