The Capsule of Cryptococcus neoformans Modulates Phagosomal pH through Its Acid-Base Properties

open access: yesmSphere, 2018
Phagosomal acidification is a critical cellular mechanism for the inhibition and killing of ingested microbes by phagocytic cells. The acidic environment activates microbicidal proteins and creates an unfavorable environment for the growth of many ...

Mycobacterium tuberculosis type VII secretion system effectors differentially impact the ESCRT endomembrane damage response [PDF]

open access: yes, 2018
Mycobacterium tuberculosis causes tuberculosis, which kills more people than any other infection. M. tuberculosis grows in macrophages, cells that specialize in engulfing and degrading microorganisms.

SpoT Induces Intracellular Salmonella Virulence Programs in the Phagosome. [PDF]

open access: yes, 2020
Guanosine tetraphosphate (ppGpp) and guanosine pentaphosphate (pppGpp), together named (p)ppGpp, regulate diverse aspects of Salmonella pathogenesis, including synthesis of nutrients, resistance to inflammatory mediators, and expression of secretion ...

Diversity and Versatility of Phagocytosis: Roles in Innate Immunity, Tissue Remodeling, and Homeostasis

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Phagocytosis, a critical early event in the microbicidal response of neutrophils, is now appreciated to serve multiple functions in a variety of cell types. Professional phagocytes play a central role in innate immunity by eliminating pathogenic bacteria,

trim-21 promotes proteasomal degradation of CED-1 for apoptotic cell clearance in C. elegans

open access: yeseLife, 2022
The phagocytic receptor CED-1 mediates apoptotic cell recognition by phagocytic cells, enabling cell corpse clearance in Caenorhabditis elegans. Whether appropriate levels of CED-1 are maintained for executing the engulfment function remains unknown ...

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

open access: yesPROTEOMICS, 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,

Histoplasma Responses to Nutritional Immunity Imposed by Macrophage Activation

open access: yesJournal of Fungi, 2019
The fungal pathogen Histoplasma capsulatum resides within the phagosome of host phagocytic cells. Within this intracellular compartment, Histoplasma yeast replication requires the acquisition of several essential nutrients, including metal ions.

Examining the Underappreciated Role of S-Acylated Proteins as Critical Regulators of Phagocytosis and Phagosome Maturation in Macrophages

open access: yesFrontiers in Immunology, 2021
Phagocytosis is a receptor-mediated process used by cells to engulf a wide variety of particulates, including microorganisms and apoptotic cells. Many of the proteins involved in this highly orchestrated process are post-translationally modified with ...

Endosomal and Phagosomal SNAREs [PDF]

open access: yesPhysiological 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.
