Electrochemiluminescence Imaging of Liposome Permeabilization by an Antimicrobial Peptide: Melittin

open access: yesChemical & Biomedical Imaging, 2023
The permeabilization of liposomes by melittin, an antimicrobial peptide (AMP), has been studied by an electrochemiluminescence (ECL) imaging strategy. The methodology consisted first of encapsulating ECL reagents in sealed giant asymmetrical liposomes ...

Melittin-Induced Permeabilization, Re-Sealing, and Re-Permeabilization of E. coli Membranes [PDF]

open access: yesBiophysical Journal, 2018
The permeabilization of model lipid bilayers by cationic peptides has been studied extensively over decades, with the bee-sting toxin melittin perhaps serving as the canonical example. However, the relevance of these studies to the permeabilization of real bacterial membranes by antimicrobial peptides remains uncertain.

(-)-Epicatechin and NADPH oxidase inhibitors prevent bile acid-induced Caco-2 monolayer permeabilization through ERK1/2 modulation

open access: yesRedox Biology, 2020
Secondary bile acids promote gastrointestinal (GI) tract permeabilization both in vivo and in vitro. Consumption of high fat diets increases bile acid levels in the GI tract which can contribute to intestinal permeabilization and consequent local and ...

Influence of the fixation/permeabilization step on peptide nucleic acid fluorescence in situ hybridization (PNA-FISH) for the detection of bacteria. [PDF]

open access: yesPLoS ONE, 2018
Fluorescence in situ Hybridization (FISH) is a versatile, widespread and widely- used technique in microbiology. The first step of FISH-fixation/permeabilization-is crucial to the outcome of the method. This work aimed to systematically evaluate fixation/

Hyperbranched Polylysine Exhibits a Collaborative Enhancement of the Antibiotic Capacity to Kill Gram-Negative Pathogens

open access: yesAntibiotics
In recent years, traditional antibiotic efficacy outcomes have rapidly diminished due to the advent of drug resistance, and the dose limitation value has increased due to the severe side effect of globalized healthcare.

Mechanisms of mitochondrial membrane permeabilization [PDF]

open access: yesCell Death & Differentiation, 2000
devoted to the topic of mitochondria andtheir role in apoptosis. The reviews are provided by some ofthe world’s leading groups working on this importantsubject.An incontrovertable role for mitochondria in inducingapoptosis and controlling cell death commitment has beenestablished. However, for the past several years, con-troversy has abounded as to the

Permeabilization of lymphocytes with polyethylene glycol 1000. Discrimination of permeabilized cells by flow cytometry [PDF]

open access: yesCytometry, 1982
AbstractThe toxicity of polyethylene glycol 1000 (PEG) used similarly as in cell hybridization experiments, has been studied by flow cytometry, measuring the light scattering and fluorescence distributions of PEG‐treated human lymphocytes stained with propidium iodide, fluorescein diacetate and acridine orange (AO).

Limited Efficacy of Nanoparticle-Assisted Electroporation for Membrane Permeabilization and Gene Electrotransfer

open access: yesPharmaceutics
Background/Objectives: Nanoparticles (NPs) were previously explored as enhancers in electroporation due to their potential to locally amplify electric fields near cell membranes, with gold nanoparticles (AuNPs) in particular showing promise in improving ...

Comprehensive benchmarking of CITE-seq versus DOGMA-seq single cell multimodal omics

open access: yesGenome Biology, 2022
The recently developed method TEA-seq and similar DOGMA-seq single cell trimodal omics assays provide unprecedented opportunities for understanding cell biology, but independent evaluation is lacking.
