High-throughput Measurement of Plasma Membrane Resealing Efficiency in Mammalian Cells [PDF]
In their physiological environment, mammalian cells are often subjected to mechanical and biochemical stresses that result in plasma membrane damage. In response to these damages, complex molecular machineries rapidly reseal the plasma membrane to restore its barrier function and maintain cell survival.

After damage, cells repair their plasma membrane in an active process that is driven by Ca2+ entering through the wound. This triggers a range of Ca2+-regulated events such as the translocation of different Ca2+-binding proteins to the wound site which ...

Membrane Tension Regulation is Required for Wound Repair [PDF]
Disruptions of the eukaryotic plasma membrane due to chemical and mechanical challenges are frequent and detrimental and thus need to be repaired to maintain proper cell function and avoid cell death.

Plasma Membrane Repair Is Regulated Extracellularly by Proteases Released from Lysosomes. [PDF]
Eukaryotic cells rapidly repair wounds on their plasma membrane. Resealing is Ca(2+)-dependent, and involves exocytosis of lysosomes followed by massive endocytosis.

Hypercapnic Acidosis Impairs Plasma Membrane Wound Resealing in Ventilator-injured Lungs [PDF]
Abstract The objective of this study was to assess the effects of hypercapnic acidosis on lung cell injury and repair by confocal microscopy in a model of ventilator-induced lung injury. Three groups of normocapnic, hypocapnic, and hypercapnic rat lungs were perfused ex vivo, either during or after injurious ventilation, with a ...

Rapid Increase in Plasma Membrane Chloride Permeability during Wound Resealing in Starfish Oocytes [PDF]
Plasma membrane wound repair is an important but poorly understood process. We used femtosecond pulses from a Ti-Sapphire laser to make multiphoton excitation–induced disruptions of the plasma membrane while monitoring the membrane potential and resistance. We observed two types of wounds that depolarized the plasma membrane. At threshold light levels,

Hydrogen Peroxide-Mediated Inhibition of Membrane Resealing Drives Synergistic Cytotoxicity of Combined Cold Atmospheric Plasma and Pulsed Electric Field Treatment. [PDF]
Cold atmospheric plasma (CAP) combined with pulsed electric fields (PEF) demonstrates synergistic cytotoxicity against HeLa cells; however, the differential contributions of short-lived versus long-lived reactive oxygen and nitrogen species (RONS) remain unclear.

Nanosecond pulsed electric fields induce cell-size-dependent selective permeabilization of urothelial cancer cells [PDF]
Plasma membrane integrity is vital for cell viability, yet its controlled disruption enables targeted delivery of therapeutic agents. Here, we examined membrane durability and repair capacity in normal and malignant urothelial cells using short, high ...

Polymorphonuclear leukocytes (PMNs) use different, strain-dependent mechanisms to kill the parasite Trichomonas vaginalis [PDF]
The unicellular parasite Trichomonas vaginalis (Tv) causes trichomoniasis, the most common non-viral sexually transmitted infection in humans. Trichomoniasis symptoms and sequelae vary substantially, and in vitro analyses have shown that strains differ ...

Preparation of resealed pig lymphocyte plasma-membrane vesicles [PDF]
Pig lymphocyte plasma-membrane vesicles that are impermeable to large molecules were prepared by means of centrifugation on a continuous dextran gradient. They were isolated in a yield of 60–80% of the total plasma membrane recovered, and were characterized as being impermeable to macromolecules by their exclusion of inulin (mol.wt.
