Phagocytosis by neutrophils - PubMed
Phagocytosis is central to the microbicidal function of neutrophils. Pathogens are initially engulfed into a plasma membrane-derived vacuole, the phagosome, which proceeds to acquire degradative properties by a complex process termed maturation.

The Neutrophil’s Choice: Phagocytose vs Make Neutrophil …
Neutrophils kill microbes via phagocytosis, generation of oxidant species, and activation of the cell proteolytic machinery, processes that have been extensively studied in the last decades. The release of neutrophil extracellular traps (NETs) vicariates frustrated or ineffective phagocytosis.
The formation and function of the neutrophil phagosome
Phagocytosis, the process of detecting and engulfing particles into an organelle called the phagosome, is key to the ability of neutrophils to kill pathogens. In neutrophils, phagocytosis is a highly specialized and efficient event.
Diversity and Versatility of Phagocytosis: Roles in Innate Immunity ...
Phagocytosis of bacteria by neutrophils. The phagocytosis of bacteria is often mediated by opsonisation of their surface with IgG and C3b molecules, which are recognized by Fcγ receptors (FcγRs) and complement receptors (CRs), respectively.
Phagocytosis, Degranulation and Extracellular Traps Release by ...
2021年5月3日 · During the resolution of inflammation, macrophages dispose apoptotic neutrophils by phagocytosis, releasing lipid mediators. These molecules play a role in re-establishing homeostasis and their absence likely leads to chronic inflammation (Buckley et al., 2014).
Phagocytosis - StatPearls - NCBI Bookshelf
2023年7月31日 · During neutrophilic phagocytosis, a pathogenic particle (such as a bacterium) is detected by Fc-Gamma receptors on the neutrophil’s cell membrane (complement receptors may also perform this function), triggering a cytoskeletal rearrangement, phagocytosing the foreign particle, and sequestering it in the phagosome. Granzyme proteases in the ...
Visualization and Quantification of Phagocytosis by Neutrophils
Phagocytosis by phagocytes such as neutrophils is a crucial part of the host innate immune response against invading pathogens. Phagocytosis is a complex process that initiates with the binding of the particles on the cell surface of the phagocytes through the interaction of pattern recognition receptors with ligands on the surface of the ...
Phagocytosis: An Immunobiologic Process - Cell Press
Neutrophils are relatively short lived and store pre-formed granules; their potent secretory and microbicidal activity is triggered by phagocytosis, resulting in degranulation, as well as initial plasma-membrane assembly of the NADPH oxidase (Flannagan et al., 2012).
The Impact of Cytokines on Neutrophils’ Phagocytosis and NET …
Authors hypothesized that CYTL1-enhanced phagocytosis of Escherichia coli by activated neutrophils is dependent on phosphorylation of protein kinase B (Akt). Additionally, CYTL1 also increased the release of ROS in LPS-stimulated neutrophils.
