Ceramide in Plasma Membrane Repair
2013The perforation of the plasmalemma by pore-forming toxins causes an influx of Ca(2+) and an efflux of cytoplasmic proteins. In order to ensure cellular survival, lesions have to be identified, plugged and removed from the membrane. The Ca(2+)-driven fusion of lysosomes with the plasma membrane leads to hydrolysis of sphingomyelin by acid ...

Plasma membrane repair in plants
Trends in Plant Science, 2009Resealing is the membrane-repair process that enables cells to survive disruption, preventing the loss of irreplaceable cell types and eliminating the cost of replacing injured cells. Given that failure in the resealing process in animal cells causes diverse types of muscular dystrophy, plasma membrane repair has been extensively studied in these ...

Annexins in plasma membrane repair
Biological Chemistry, 2016Abstract Disruption of the plasma membrane poses deadly threat to eukaryotic cells and survival requires a rapid membrane repair system. Recent evidence reveal various plasma membrane repair mechanisms, which are required for cells to cope with membrane lesions including membrane fusion and replacement strategies, remodeling of cortical ...

Repairing the tears: dysferlin in muscle membrane repair
Trends in Molecular Medicine, 2003Many muscular dystrophies arise from enhanced muscle degeneration, but one muscular dystrophy subtype has now been shown to arise from defective muscle membrane repair. Mutations in the gene encoding dysferlin cause muscular dystrophy, and recent work has demonstrated a role for this protein in resealing muscle membrane tears.

Lysosomes and plasma membrane repair
2019The ability of repairing damages on the plasma membrane is crucial for cell survival. When damaged, eukaryotic cells are able to recover plasma membrane integrity within a few seconds, thus avoiding cytoplasm leakage and cell death. The process is driven by the influx of extracellular calcium which triggers a multitude of intracellular effects that ...

Repair of Experimental Tympanic Membrane Perforations
Acta Oto-Laryngologica, 1980In this investigation the healing pattern of experimental central and marginal pars tensa perforations in cats and rats was studied by using light and scanning electronmicroscopic techniques. The perforations were closed by hyperplastic squamous epithelium exhibiting a marked keratin production.

Annexins and plasma membrane repair
2019Plasma membrane wound repair is a cell-autonomous process that is triggered by Ca2+ entering through the site of injury and involves membrane resealing, i.e., re-establishment of a continuous plasma membrane, as well as remodeling of the cortical actin cytoskeleton.

Flexor tendon repair with amniotic membrane
International Orthopaedics, 2020Flexor tendon adhesion to tissues is one of the most frequent complications reported after flexor tendon repair. The human amniotic membrane (HAM) was used to wrap the tendon repair site to decrease fibrotic response and tendon adhesion.A total of 19 patients with flexor tendon injuries were subjected to surgical repair.

Plasma Membrane Disruption: Repair, Prevention, Adaptation
Annual Review of Cell and Developmental Biology, 2003▪ Abstract Many metazoan cells inhabit mechanically stressful environments and, consequently, their plasma membranes are frequently disrupted. Survival requires that the cell rapidly repair or reseal the disruption. Rapid resealing is an active and complex structural modification that employs endomembrane as its primary building block, and ...

A kinetic model of membrane repair
Canadian Journal of Physiology and Pharmacology, 1970Two microelectrodes are inserted into a Xenopus laevis egg. Rectangular current pulses are injected through one microelectrode and the voltage induced across the cell membrane is measured via the second electrode. The transmembrane resistance, as deduced from the injected current and the measured voltage, is taken as a measure of membrane integrity ...
