Phagocytosis [PDF]

Current Biology, 2011
SummaryPhagocytosis is defined as the receptor-mediated engulfment of large (≥0.5 μm) particles into plasma membrane-derived vacuoles called phagosomes. Following scission from the plasma membrane, the phagosomes undergo a maturation process, sequentially fusing with endosomes and lysosomes, ultimately becoming phagolysosomes — highly acidic and ...

Phagocytosis is a primary determinant of pulmonary clearance of clinical Klebsiella pneumoniae isolates

Frontiers in Cellular and Infection Microbiology, 2023
IntroductionKlebsiella pneumoniae (Kp) is a common cause of hospital-acquired pneumonia. Although previous studies have suggested that evasion of phagocytic uptake is a virulence determinant of Kp, few studies have examined phagocytosis sensitivity in ...

Complement-receptor-3 and scavenger-receptor-AI/II mediated myelin phagocytosis in microglia and macrophages

Neurobiology of Disease, 2003
Microglia and macrophages express the αM/β2 integrin complement-receptor-3 (CR3/MAC-1; CD11b/CD18) and scavenger-receptor-AI/II (SRAI/II). Both can mediate myelin phagocytosis.

Regulatory Role of Fc Receptor in mIgM+ B Lymphocyte Phagocytosis in Flounder (Paralichthys olivaceus)

Frontiers in Immunology, 2021
Fc receptor (FcR) is an important opsonin receptor on the surface of immune cells, playing an important role in antibody-dependent cell-mediated immunity.

Decreased neutrophil bactericidal activity during phagocytosis of a slime-producing Staphylococcus aureus strain. [PDF]

, 2000
Phagocytosis and intracellular killing by bovine polymorphonuclear leukocytes (PMN) are important host defence mechanisms against mastitis caused by Staphylococcus aureus. We compared the phagocytosis and overall killing of a non slime-producing (NSP) S.

Phagocytosis in Teleosts. Implications of the New Cells Involved

Biology, 2015
Phagocytosis is the process by which cells engulf some solid particles to form internal vesicles known as phagosomes. Phagocytosis is in fact a specific form of endocytosis involving the vesicular interiorization of particles. Phagocytosis is essentially

Phagocytosis of microparticles increases responsiveness of macrophage-like cell lines U937 and THP-1 to bacterial lipopolysaccharide and lipopeptide

Scientific Reports, 2021
Following bacterial infection, macrophages produce pro-inflammatory cytokines in response to bacterial cell components, including lipopolysaccharide (LPS) and lipopeptide, and simultaneously phagocytize and digest the invading bacteria.

Interplay between FGFR2b-induced autophagy and phagocytosis: role of PLCγ-mediated signalling [PDF]

, 2017
Signalling of the epithelial splicing variant of the fibroblast growth factor receptor 2 (FGFR2b) induces both autophagy and phagocytosis in human keratinocytes.

Complement receptor-3 negatively regulates the phagocytosis of degenerated myelin through tyrosine kinase Syk and cofilin

Journal of Neuroinflammation, 2012
Background Intact myelin, which normally surrounds axons, breaks down in Wallerian degeneration following axonal injury and during neurodegenerative diseases such as multiple sclerosis.

The effects of honey compared with sucrose and a sugar-free diet on neutrophil phagocytosis and lymphocyte numbers after long-term feeding in rats [PDF]

, 2007
To determine whether honey and sucrose would have differential effects on levels of neutrophil phagocytosis after long-term feeding 36 2-month old Sprague Dawley rats were fed a powdered diet that was either sugar-free or contained 7.9% sucrose or 10 ...
