The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

FEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Mechanism of inducible nitric oxide synthase exclusion from mycobacterial phagosomes.

PLoS Pathogens, 2007
Mycobacterium tuberculosis is sensitive to nitric oxide generated by inducible nitric oxide synthase (iNOS). Consequently, to ensure its survival in macrophages, M. tuberculosis inhibits iNOS recruitment to its phagosome by an unknown mechanism.

Phagosome-lysosome fusion

Biochemical Society Transactions, 1986
Phagosome-lysosome fusion plays an important role in the destruction of micro-organisms by phagocytic cells. Several approaches have been used to study the determinants of phagosome-lysosome fusion in mouse macrophages. Fusion can be assayed by electron microscopy using horseradish peroxidase or thorium dioxide as a marker for secondary lysosomes or by

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

The distinct fate of smooth and rough Mycobacterium abscessus variants inside macrophages [PDF]

Open Biology, 2016
Mycobacterium abscessus is a pathogenic, rapidly growing mycobacterium responsible for pulmonary and cutaneous infections in immunocompetent patients and in patients with Mendelian disorders, such as cystic fibrosis (CF). Mycobacterium abscessus is known

Molecular characterization of phagosomes.

Journal of Biological Chemistry, 1994
The transformation of newly formed phagosomes into mature phagolysosomes is a process that involves a complex series of interactions between phagosomes and other vacuolar organelles. The machinery required by phagosomes to mediate these interactions is poorly understood.

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

Advanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

LC3B Mediated SETDB1‐Accounted Alcoholic Steatohepatitis via Lipidation‐Dependent LAP and Lipidation‐Independent Nuclear Stabilization

Advanced Science, EarlyView.
SETDB1 is progressively downregulated in ALD, correlating with disease severity. SETDB1 deficiency impairs LAP by disrupting Rubicon membrane localization, leading to defective lipid droplet clearance. Concurrently, loss of SETDB1 reduces nuclear LC3B, causing R‐loop accumulation and cGAS‐STING‐driven inflammation. Lipidated LC3B mediates LAP‐dependent

Isolation of Phagosomes from Dendritic Cells by Using Magnetic Beads

Bio-Protocol, 2013
Phagosomes are intracellular organelles in dendritic cells in which pathogens such as viruses, bacteria and parasites are internalised to be proteolysed and killed.
