Transcriptional adaptation of Mycobacterium tuberculosis within macrophages: Insights into the phagosomal environment [PDF]

, 2003
Little is known about the biochemical environment in phagosomes harboring an infectious agent. To assess the state of this organelle we captured the transcriptional responses of Mycobacterium tuberculosis (MTB) in macrophages from wild-type and nitric ...

SWAP70 Organizes the Actin Cytoskeleton and Is Essential for Phagocytosis

Cell Reports, 2016
Actin plays a critical role during the early stages of pathogenic microbe internalization by immune cells. In this study, we identified a key mechanism of actin filament tethering and stabilization to the surface of phagosomes in human dendritic cells ...

Two PI 3-kinases and one PI 3-phosphatase together establish the cyclic waves of phagosomal PtdIns(3)P critical for the degradation of apoptotic cells. [PDF]

PLoS Biology, 2012
Phosphatidylinositol 3-phosphate (PtdIns(3)P) is a signaling molecule important for many membrane trafficking events, including phagosome maturation. The level of PtdIns(3)P on phagosomes oscillates in two waves during phagosome maturation.

Bordetella parapertussis Survives inside Human Macrophages in Lipid Raft-Enriched Phagosomes [PDF]

, 2014
Bordetella parapertussis is a human pathogen that causes whooping cough. The increasing incidence of B. parapertussis has been attributed to the lack of cross protection induced by pertussis vaccines. It was previously shown that B. parapertussis is able

Analysis of phagosomal proteomes: From latex‐bead to bacterial phagosomes [PDF]

PROTEOMICS, 2010
Abstract Phagosomal proteome characterization has contributed significantly to the understanding of host–pathogen interaction and the mechanism of infectious diseases caused by intracellular bacteria. The latex bead‐containing phagosome has been widely used as a model system to study phagosomal proteomes at a global level. In contrast,

Rab GTPases in Immunity and Inflammation

Frontiers in Cellular and Infection Microbiology, 2017
Strict spatiotemporal control of trafficking events between organelles is critical for maintaining homeostasis and directing cellular responses. This regulation is particularly important in immune cells for mounting specialized immune defenses.

Class IA phosphatidylinositol 3-kinase p110α regulates phagosome maturation. [PDF]

PLoS ONE, 2012
Of the various phosphatidylinositol 3- kinases (PI3Ks), only the class III enzyme Vps34 has been shown to regulate phagosome maturation. During studies of phagosome maturation in THP-1 cells deficient in class IA PI3K p110α, we discovered that this PI3K ...

Endosomal and Phagosomal SNAREs [PDF]

Physiological Reviews, 2018
The soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein family is of vital importance for organelle communication. The complexing of cognate SNARE members present in both the donor and target organellar membranes drives the membrane fusion required for intracellular transport.
