Advancing Extracellular Vesicle Research: A Review of Systems Biology and Multiomics Perspectives

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound vesicles secreted by various cell types into the extracellular space and play a role in intercellular communication. Their molecular cargo varies depending on the cell of origin and its functional state.

SARS-CoV-2 virulence factor ORF3a blocks lysosome function by modulating TBC1D5-dependent Rab7 GTPase cycle

Nature Communications
SARS-CoV-2, the causative agent of COVID-19, uses the host endolysosomal system for entry, replication, and egress. Previous studies have shown that the SARS-CoV-2 virulence factor ORF3a interacts with the lysosomal tethering factor HOPS complex and ...

Human Rab7 mutation mimics features of Charcot–Marie–Tooth neuropathy type 2B in Drosophila

Neurobiology of Disease, 2014
Charcot–Marie–Tooth disease type 2B (CMT2B) is an inherited axonal peripheral neuropathy. It is characterised by prominent sensory loss, often complicated by severe ulcero-mutilations of toes or feet, and variable motor involvement. Missense mutations in

Synergistic antiviral activity against human adenovirus through combination of itraconazole and brincidofovir

British Journal of Pharmacology, EarlyView.
Background and Purpose Human adenovirus (HAdV) causes respiratory or gastrointestinal tract infections depending on the virus subtype. While HAdV infections are generally self‐limiting in immunocompetent people, they can result in significant morbidity and mortality in immunocompromised adults and children.

Structural basis for recruitment of RILP by small GTPase Rab7 [PDF]

The EMBO Journal, 2005
Rab7 regulates vesicle traffic from early to late endosomes, and from late endosomes to lysosomes. The crystal structure of Rab7-GTP in complex with the Rab7 binding domain of RILP reveals that Rab7 interacts with RILP specifically via two distinct areas, with the first one involving the switch and interswitch regions and the second one consisting of ...

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.

RNF13 is a previously undescribed interactor of iduronate 2‐sulfatase that modifies its glycosylation and maturation

The FEBS Journal, EarlyView.
Iduronate 2‐sulfatase (IDS; purple) is expressed as a precursor protein that goes through multiple steps of maturation, modification, and trafficking to become an active lysosomal enzyme that degrades glycosaminoglycans. Our study shows that the transmembrane ubiquitin ligases RNF13 (orange) and RNF167 (pink) heterodimerize, affecting IDS intracellular

Retrograde trafficking of Argonaute 2 acts as a rate-limiting step for de novo miRNP formation on endoplasmic reticulum–attached polysomes in mammalian cells [PDF]

, 2020
microRNAs are short regulatory RNAs in metazoan cells. Regulation of miRNA activity and abundance is evident in human cells where availability of target messages can influence miRNA biogenesis by augmenting the Dicer1-dependent processing of precursors ...

Functional coupling of microtubules to membranes - implications for membrane structure and dynamics [PDF]

, 2012
The microtubule network dictates much of the spatial patterning of the cytoplasm, and the coupling of microtubules to membranes controls the structure and positioning of organelles and directs membrane trafficking between them.
