Niosomes and polymeric chitosan based vesicles bearing transferrin and glucose ligands for drug targeting [PDF]

, 2000
PURPOSE: To prepare polymeric vesicles and niosomes bearing glucose or transferrin ligands for drug targeting. METHODS: A glucose-palmitoyl glycol chitosan (PGC) conjugate was synthesised and glucose-PGC polymeric vesicles prepared by sonication of ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Explosive cell lysis as a mechanism for the biogenesis of bacterial membrane vesicles and biofilms

Nature Communications, 2016
Many bacteria release DNA and membrane vesicles through unclear mechanisms. Here, the authors show that a prophage endolysin is involved in the explosive lysis of a sub-population of cells in Pseudomonas aeruginosa, releasing cytoplasmic content and ...

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Imaging optical thicknesses and separation distances of phospholipid vesicles at solid surfaces [PDF]

, 1992
We present the application of reflection interference contrast microscopy (RICM) (1) to map the optical density of supported bilayers and vesicles and (2) to image the contact profile of phospholipid vesicles at surfaces.

Modulation of gene transcription and epigenetics of colon carcinoma cells by bacterial membrane vesicles

Scientific Reports, 2018
Interactions between bacteria and colon cancer cells influence the transcription of the host cell. Yet is it undetermined whether the bacteria itself or the communication between the host and bacteria is responsible for the genomic changes in the ...

Development of Artificial Cell Models Using Microfluidic Technology and Synthetic Biology

Micromachines, 2020
Giant lipid vesicles or liposomes are primarily composed of phospholipids and form a lipid bilayer structurally similar to that of the cell membrane. These vesicles, like living cells, are 5–100 μm in diameter and can be easily observed using an optical ...

Membrane vesicles

Journal of Extracellular Vesicles, 2017
Extracellular vesicles (EVs) are not only intensively studied to increase our fundamental knowledge on their functioning, but also for diagnosis, therapeutics and drug delivery purposes. To improve the current and potential applications of EVs, a fundamental understanding of their stability, structure, and function is crucial.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Recruitment of AP-1 clathrin adaptors to liposomal membranes [PDF]

, 2004
Protein and membrane traffic between organelles within the endocytic and exocytic pathway is mediated most prominently by coated vesicles. These vesicles are formed by the assembly of cytosolic coat proteins onto the donor membrane, which deform it into ...
