Marine Delivery Vehicles: Molecular Components and Applications of Bacterial Extracellular Vesicles

Marine Drugs
In marine ecosystems, communication among microorganisms is crucial since the distance is significant if considered on a microbial scale. One of the ways to reduce this gap is through the production of extracellular vesicles, which can transport ...

Delivery of virulence factors by bacterial membrane vesicles to mammalian host cells

, 2020
Bacterial membrane vesicles represent a universal secretion mechanism enabling both Gram-negative and Gram-positive organisms to transfer cargo to eukaryotic cells, as well as to other bacterial cells.

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

Advanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

Emerging roles of extracellular vesicles in the adaptive response of tumour cells to microenvironmental stress. [Elektronisk resurs]

, 2013
Cells are constantly subjected to various types of endogenous and exogenous stressful stimuli, which can cause serious and even permanent damage. The ability of a cell to sense and adapt to environmental alterations is thus vital to maintain tissue ...

Adaptations of Bacterial Extracellular Vesicles in Response to Antibiotic Pressure

International Journal of Molecular Sciences
Extracellular vesicles (EVs) are nanometer-sized lipid structures actively secreted by Gram-negative and Gram-positive bacteria, representing a sophisticated microbial adaptation and communication strategy. These structures are involved in biomolecular transport, the regulation of biological processes, the modulation of host–pathogen interactions, and ...

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

Advanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

A beginner's guide to study extracellular vesicles in human blood plasma and serum

Blood is the most commonly used body fluid for obtaining and studying extracellular vesicles (EVs). While blood is a standard choice for clinical analysis, using blood as a source of EVs introduces multiple layers of complexity.

A Chiral Virus‐Like Nanoplatform That Broadly Mediates Antibiotic Delivery to the Brain for Bacterial Meningitis Therapy

Advanced Science, EarlyView.
Chiral virus‐mimicking mesoporous silica nanostructures (CVSNs) efficiently transport diverse antibiotics across the blood–brain barrier (BBB) into brain parenchyma and cerebrospinal fluid. By enhancing delivery to microglia and astrocytes, CVSNs improve antibiotic bioavailability and therapeutic efficacy against both Gram‐negative and Gram‐positive ...

Supramolecular Assembly of an Antimicrobial Peptide Into a Pore

Angewandte Chemie, EarlyView.
Supramolecular assembly of an AMP is linked to transport across the Staphylococcus aureus membrane. ABSTRACT Antimicrobial peptides (AMPs) have long been ascribed the ability to form pores. These structures, some observed, others inferred, vary in their mechanisms of action, though most are associated with lysis.
