Phagosomal transport depends strongly on phagosome size [PDF]

Scientific Reports, 2017
AbstractMacrophages internalize pathogens for intracellular degradation. An important part of this process is the phagosomal transport from the cell periphery to the perinuclear region. Biochemical factors are known to influence the fate of phagosomes. Here, we show that the size of phagosomes also has a strong influence on their transport.

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis

Hepatology, EarlyView., 2022
EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

The phagosome proteome: insight into phagosome functions. [PDF]

The Journal of cell biology, 2001
Phagosomes are key organelles for the innate ability of macrophages to participate in tissue remodeling, clear apoptotic cells, and restrict the spread of intracellular pathogens. To understand the functions of phagosomes, we initiated the systematic identification of their proteins.

TRPC6 channel translocation into phagosomal membrane augments phagosomal function [PDF]

Proceedings of the National Academy of Sciences, 2015
SignificanceHistorically, pulmonary infections treated with antibiotics killed bacteria while selecting for the unintended development of pathogenic resistance. One strategy to circumvent antibiotic resistance in pulmonary infection involves targeting the host phagosome and augmenting its function.

Microtubule Motor Transport of Organelles in a Specialized Epithelium: The RPE

Frontiers in Cell and Developmental Biology, 2022
The retinal pigment epithelium (RPE) is a uniquely polarized epithelium that lies adjacent to the photoreceptor cells in the retina, and is essential for photoreceptor function and viability.

Mycobacterium tuberculosis phagosome [PDF]

Molecular Microbiology, 1999
The arrest of Mycobacterium tuberculosis phagosome maturation in infected macrophages is a phenomenon of dual significance both for the pathogenesis of tuberculosis and as a model system to study interference of microbes with membrane trafficking and organelle biogenesis in host cells.

Impaired Cargo Clearance in the Retinal Pigment Epithelium (RPE) Underlies Irreversible Blinding Diseases

Cells, 2018
Chronic degeneration of the Retinal Pigment Epithelium (RPE) is a precursor to pathological changes in the outer retina. The RPE monolayer, which lies beneath the neuroretina, daily internalises and digests large volumes of spent photoreceptor outer ...

Real-time imaging of Leishmania mexicana-infected early phagosomes: a study using primary macrophages generated from green fluorescent protein-Rab5 transgenic mice [PDF]

, 2009
The small GTPase Rab5 is a key regulator of endosome/phagosome maturation and in intravesicular infections marks a phagosome stage at which decisions over pathogen replication or destruction are integrated.

The Lipid Raft-Associated Protein Stomatin Is Required for Accumulation of Dectin-1 in the Phagosomal Membrane and for Full Activity of Macrophages against Aspergillus fumigatus

mSphere, 2023
Alveolar macrophages belong to the first line of defense against inhaled conidia of the human-pathogenic fungus Aspergillus fumigatus. In lung alveoli, they contribute to phagocytosis and elimination of conidia.
