(2009). PLD-mediated activation of PI5K relies on the formation of PA, which itself is able to determine the spatial localization of PI5K as well as cause its activation (Roach et al., 2012). Development of cell therapy and regenerative medicine using stem cells is expanding the medical industry and businesses as well as increasing the understanding of the nature of the cell itself. One of the roles of lipid mobility may be to allow for the movement of individual lipids to form microdomains near the site of injury, which has been shown to be important for repair (Vaughan et al., 2014), perhaps by facilitating lipid-mediated signaling. The reduction in membrane tension is likely due directly to the addition of phospholipids to reduced lipid packing, as well as due in part to the cytoskeletal remodeling associated with vesicular transport at the plasma membrane. Unlike Annexin 5 that forms a lattice structure at the wound edge (Bouter et al., 2011), Annexins A4 and A6 work together to mediate constriction of the wounded edges of the plasma membrane, aiding in the closure of the wound (Boye et al., 2017). Membrane stabilization by modified steroid offers a potential therapy for muscular dystrophy due to dysferlin deficit, Transverse distribution of plasma membrane bilayer cholesterol: Picking sides.

Structurally, the conical ceramide molecule results in negative membrane curvature associated with rapid nucleation of ESCRT complex proteins (Lee, Kai, Carlson, Groves, & Hurley, 2015). Cheng JP, Mendoza-Topaz C, Howard G, Chadwick J, Shvets E, Cowburn AS, Nichols BJ (2015). In either case, the outward budding of the membrane produced by these ceramide-rich microdomains is thought to assist in microvesicle shedding. The nanoclusters appear to form specifically at the boundary of ordered raft domains and disordered domains where signaling lipids such as PIP3 and PIP2 are found. Pollet H, Conrard L, Cloos A-S, & Tyteca D (2018). PDF Membrane damage and repair - osuchildrensmusclegroup.org Different cell-intrinsic PM repair mechanisms have been reported, including membrane fusion and replacement strategies (via exocytosis-mediated repair), removal of damaged membranes (by. Further, the complexity of signaling afforded by lipids allows the cell to coordinate a highly organized response to injury across space and time (Figure 1B). Unlike phospholipids and sphingolipids, which are structurally analogous, cholesterol is composed of a steroid backbone that results in a planar and more rigid molecule. Mechanochemical feedback control of dynamin independent endocytosis modulates membrane tension in adherent cells, Long-term Potentiation of Wound-induced Exocytosis and Plasma Membrane Repair Is Dependant on cAMP-response Element-mediated Transcription via a Protein Kinase C-and p38 MAPK-dependent Pathway. This phenomenon may be explained by the kinetic energy imparted on the membrane lipids by mechanical disruption, which can result in lipid mixing without relying on membrane tension (Petersen, Chung, Nayebosadri, & Hansen, 2016). PI (3, 4, 5) P3 and PI (4, 5) P2 lipids target proteins with polybasic clusters to the plasma membrane, The membrane and lipids as integral participants in signal transduction: lipid signal transduction for the non-lipid biochemist. Sealing holes in cellular membranes | The EMBO Journal In. sharing sensitive information, make sure youre on a federal These observations align well with the observed kinetics of membrane resealing, which suggests that plasma membrane wounds can be resealed within 30 seconds; however, restoration of membrane tension shortly afterward is required for successful membrane remodeling and completion of the repair process. The tight packing, along with the preference of cholesterol to intercalate the acyl chains of sphingomyelin creates the liquid-ordered membrane domains, such as the so-called lipid rafts (Van Meer et al., 2008) (Figure 2C). 2013 Dec 19;(82):e50848. Clipboard, Search History, and several other advanced features are temporarily unavailable. Radiation Effects on Cells & DNA | Let's Talk Science Calcium-regulated exocytosis is required for cell membrane resealing. Federal government websites often end in .gov or .mil. As lipids comprise the bulk of the plasma membrane, the acts of injury, resealing, and remodeling all directly impinge upon the plasma membrane lipids. One model explaining membrane injury in dystrophin-deficient muscle fibers proposes that an initial injury causes a local influx of calcium and a local region of hypercontraction.

Many of the sphingolipids also contain a glycosidically bound carbohydrate moiety causing formation of the glycosphingolipids. Their localization and function in response to injury is controlled by the patterning of anionic lipids such as PS, which is present at the wound edge and is a known binding partner of annexins (Gerke, Creutz, & Moss, 2005). Necrosis is a progressive failure of essential metabolic and structural cell components usually in the cytoplasm. Biosci Rep. 2023 Feb 27;43(2):BSR20220765. J Cell Biol.

Bookshelf Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. With larger injuries, the opposing force of membrane tension exceeds the resealing forces of lipid disorder at the edges of the disruption, negating the driving forces of spontaneous membrane resealing. Furthermore, ASM activity at the injury site would locally produce ceramide from sphingomyelin. While PLD is also activated by calcium, recent findings have provided insight into the role of mechanical stress on initiating lipid signaling regulated by PLD (Petersen et al., 2016). Live tracking of inter-organ communication by endogenous exosomes in vivo. 2017 Jul 11;114(28):7283-7288. doi: 10.1073/pnas.1705059114. Careers.

It also works extracellularly to improve repair of injured muscle and other cells (Gushchina et al., 2017; Weisleder et al., 2012). Caveolae internalization repairs wounded cells and muscle fibers, Regulation of endocytosis, exocytosis, and shape by membrane tension, Paper presented at the Cold Spring Harbor symposia on quantitative biology. When the cell is under stress, and the amount of ROS increases, the number of methionine "errors" is ramped up tenfold, allowing new proteins to be even more resistant to attack. Membrane-stabilizing copolymers confer marked protection to dystrophic skeletal muscle in vivo, Molecular Therapy-Methods & Clinical Development. The plasma membrane is semi-permeable, allowing the cell to communicate with and utilize resources from its surrounding environment. Being the most abundant component of the plasma membrane, lipids are also essential player in the process of plasma membrane repair; however, much of the research committed to identifying the mechanisms of plasma membrane repair has focused on the proteins associated with plasma membrane repair (Cooper & McNeil, 2015). Plasma membrane wounding and repair in pulmonary diseases, American Journal of Physiology-Lung Cellular and Molecular Physiology, Membrane repair: mechanisms and pathophysiology. (A) Plasma membrane phospholipids are generated from biosynthetic pathways, which rely on formation of the molecule diacylglycerol (DAG) or cytidine diphosphate diacylglycerol (CDP-DAG) from phosphatidic acid (PA). For example, Annexin 5 accumulates first to form a lattice structure, which provides a force opposing the tension at the wound edge (Bouter et al., 2011). However, all cells are susceptible to plasma membrane damage, which results in the mixture of the intracellular fluid and extracellular milieu and can result in death if the damage is not rapidly repaired. This study showed that endocytosis occurs after membrane resealing and is mediated by the CLIC/GEEC pathway effector GRAF1, which is implicated in repair of muscle fiber plasma membrane injury (Lenhart et al., 2015). 2012 Sep-Oct;52(3-4):191-5. doi: 10.1016/j.ceca.2012.06.003. Due to the differences in the three-dimensional conformations of membrane lipids, a change in their distribution changes the lipid packing density in a given lipid domain. In contrast to PC, sphingomyelin forms a taller and narrower cylinder, which along with the configuration of its acyl chains, allowing this lipid to pack more tightly than phospholipids (Cebecauer et al., 2018).

'Resealing' is the emergency response required for cell . Tam C, Idone V, Devlin C, Fernandes MC, Flannery A, He X, Andrews NW (2010). Similar to the changes in tension described above, the fluidity of the plasma membrane is also dynamic after injury. Inositol is bound to the phosphate group in this phospholipid. Self-repairing cells: How single cells heal membrane ruptures and doi: 10.7554/eLife.80778. Among these lipids, PC is the most abundant in the plasma membrane and is formed by adding choline to the DAG backbone. Repair of injured cells is tied closely to tissue repair and regeneration, as shown by studies demonstrating release of inflammatory mediators, including small molecules, peptides and proteins that signal to cells in the inflammatory and regenerative systems to initiate a tissue level reparative response. Another role identified for lysosomal fusion in membrane repair is the secretion of the lipid modifying enzyme acid sphingomyelinase (ASM) (Defour et al., 2014; Tam et al., 2010). While tension acts at the level of an entire membrane, the physical properties of the individual lipids and lipid domains dynamically guide the local changes required for adapting to the change in tension.

Membrane damage: Damage to the cell membrane disturbs the state of cell electrolytes, e.g. Treatment with Recombinant Human MG53 Protein Increases Membrane Integrity in a Mouse Model of Limb Girdle Muscular Dystrophy 2B. The cell membrane is an extremely pliable structure composed primarily of two layers of phospholipids (a "bilayer"). Here we will discuss the current knowledge of how lipids facilitate plasma membrane repair by regulating membrane structure and signaling to coordinate the repair response, and will briefly note how lipid involvement extends beyond plasma membrane repair to the tissue repair response. The radiation could pass through the cell without damaging the DNA. Interestingly, several methods for PIP2 micro-domain formation may allow for this to occur after plasma membrane injury. Membrane repair is a conserved physiologic process in multiple tissues Organ Type of mechanical force Principal cells stressed Cell wounding Similar inter-leaflet heterogeneity exists among sphingolipids, with the glycosphingolipids maintained exclusively in the outer leaflet. An organelle (think of it as a cell's internal organ) is a membrane bound structure found within a cell. Prior to increase in shear force, PLD associates with lipid rafts, physically segregated from its activator PIP2 and its substrate PC (Petersen et al., 2016). In some cases, these forces are benign, such as membrane protrusion driven by cortical actin polymerization (Pontes, Monzo, & Gauthier, 2017). (B) Phospholipid biosynthesis depends on multiple inputs from metabolism (glycerol-3-phosphate) and extracellular import (choline and ethanolamine). Biophys J. An official website of the United States government. These remodeling events actively promote plasma membrane repair; however, they also act as extensions of the repair response and may continue long after successful resealing in order to restore the plasma membrane to its pre-injury state. This is notable because it is hypothesized that a beneficial role of decreasing membrane fluidity is preventing the spread of harmful lipid hydroperoxides, which likely form in the oxidative environment near the site of injury (Braughler & Hall, 1992; Hall, Wang, Miller, Cebak, & Hill, 2018). PA is itself generated primarily from glycerol-3-phosphate, which is a product of glycolysis. However, ceramide formation also changes membrane dynamics by forming rigid microdomains and potentially by displacing cholesterol from lipid rafts (London, 2004).

Front Cell Dev Biol. Drescher DG, Drescher MJ, Selvakumar D, Annam NP. Plasma membrane integrity in health and disease: significance and While a common thread in lipid signaling is the modification of a target protein, either directly or indirectly, the numerous mechanisms lipids use to achieve this outcome allows for a great diversity of signaling. This helps to remodel the newly repaired plasma membrane (Middel et al., 2016), but may also serve to potentiate tissue inflammation. Cell Regen. Plasma Membrane Repair: Norma Andrews - iBiology This homeostatic process of vesicle fusion that maintains the plasma membrane at rest also enables plasma membrane repair through regulated fusion of vesicles triggered by calcium influx following plasma membrane injury (Horn & Jaiswal, 2018; McNeil & Steinhardt, 2003). Indeed, mechanical injury of healthy cells transiently increases the mobile fraction of plasma membrane lipids by as much as 9% (Sreetama et al., 2018). It must repair itself, first by stopping the loss of cytoplasm, and then regenerate by rebuilding structures that were damaged or lost. This process is more efficient when GTPases and their regulatory proteins (which are themselves regulated by lipids) are clustered (Ligeti, Dagher, Hernandez, Koleske, & Settleman, 2004). These examples of organizational heterogeneity, along with the differences among the lipids that comprise the plasma membrane confer a variety of structural and signaling properties to the plasma membrane and allow the plasma membrane to mount and sustain localized signaling despite being fully interconnected and fluid. For example, the cytoskeletal proteins interact with membrane lipids to supply the cortical tension that regulates the global shape of the plasma membrane and produces cell movement (Cebecauer et al., 2018; Sezgin et al., 2017). Skalman LN, Holst MR, Larsson E, & Lundmark R (2018). Lipid-soluble molecules and some small molecules can permeate the membrane, but the lipid bilayer effectively repels the many large . Membrane Damage - an overview | ScienceDirect Topics Acute and chronic release of lipids and free fatty acids following cell and tissue injury has been widely recognized to be involved in the process of tuning the inflammatory and subsequent tissue repair response. Abstract. They include glycerophosphocholines, glycerophosphoglycerols, glycerophosphoinositols, as well as triacylglycerols (Taverna, Nanney, Pollins, Sindona, & Caprioli, 2011). the contents by NLM or the National Institutes of Health. While PLC is able to cleave PC, the classic substrate of PLC is PIP2, which upon cleavage generates the membrane bound DAG and the cytosolic inositol trisphosphate (IP3) both of which are increased after injury (Lamb, Harper, McKinney, Rzigalinski, & Ellis, 1997; Vaughan et al., 2014). See this image and copyright information in PMC. Without adequate remodeling, the plasma membrane protein and lipid composition would change dramatically, particularly after repeat injuries, and no longer function as in its pre-injury state. Plasma membrane lipids can be grouped into three classes glycerophospholipids, sphingolipids, and sterols. These lipids also exist at the boundary of lipid-ordered domains, such as lipid rafts, indicating that GTPases are targeted to these regions where protein accumulation at the membrane is common (Moissoglu et al., 2014), increasing their relative signaling capacity. While it is unclear whether caveolae can provide structural assistance to the damaged membrane in the context of a large membrane injury (as opposed to sub-injury threshold stress, (Sinha et al., 2011)), caveolae may still provide a signaling function during the repair process. Similarly, peak PIP2 accumulation at the injury site occurred 45 seconds post-injury in Xenopus oocytes (Vaughan et al., 2014). Calcium has been identified as the key trigger to activate an effective membrane repair response that utilizes exocytosis and endocytosis to repair a membrane tear, or remove a membrane pore. Rapid actin-cytoskeletondependent recruitment of plasma membranederived dysferlin at wounds is critical for muscle membrane repair. The membrane patch may serve only temporarily as a surface barrier replacement that is subsequently remodeled and removed via exocytic and/or endocytic machinery. An official website of the United States government. Interphase has three stages: G1, S and G2. This results in the replacement of half of the body's adipocytes in 8 years. Failure of injured cells to repair results in cell death and activates a tissue repair response. Another role of plasma membrane lipids in wound detection is that of mechanosensing provided by lipid microdomains, such as caveolae, by way of sensing injury-triggered alteration in membrane stress (see Section 3.1). Zuzek A, Fan JD, Spaeth CS, & Bittner GD (2013). These same processes also work to dynamically control membrane fluidity by regulating the distribution of phospholipids, sphingolipids, and cholesterol in the membrane. Cell Energy, Cell Functions | Learn Science at Scitable - Nature Accumulation of GRAF1 at the repair site occurs 2 minutes after injury, supporting its potential role in membrane remodeling following resealing. Cell membrane disruption initially stimulates repair responses in the wounded cell itself, as described in this chapter, but other cells can subsequently respond to membrane disruption to "help" repair the membrane of the injured cell. increased lipid fluidity described in Section 3) and allows for the membrane associated PLD to diffuse outward from lipid rafts and interact with PIP2 in order to metabolize PC. The most abundant component of the cells plasma membrane is the lipids. Scar/WAVE has Rac GTPase-independent functions during cell wound repair. Phospholipids in particular show inter-leaflet heterogeneity. The second stage of tissue repair, regeneration, makes use of signaling by different lipids, one of which is sphingolipid. Despite the many different types of tissue, there is a common repair program involved in tissue repair. Rac1, a Rho family GTPase required for repair (Verboon & Parkhurst, 2015), forms nanoclusters at sites enriched in PA and PIP3, whose roles in regulating Rac1 appear to be non-overlapping (Maxwell et al., 2018). 2018 Apr 23;28(8):R392-R397. Zhang KS, Blauch LR, Huang W, Marshall WF, Tang SKY. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface. Living systems do this using structures or waterproof materials to prevent or slow liquid movement. Poloxamer 188 facilitates the repair of alveolus resident cells in ventilator-injured lungs, American journal of respiratory and critical care medicine. Presence of PS at the free membrane wound edge helps directs the annexin proteins to this site in a calcium-dependent manner, where they perform vital functions required for stabilization and shaping of the repairing membrane (see Section 3.3). While membrane stabilization at the time of injury appears to improve membrane repair, a chronically rigid plasma membrane may inhibit the beneficial effects of transient lipid mobility after injury. Further, PA is implicated in processes critical to the success of membrane repair such as vesicle fusion with the plasma membrane and GTPase signaling (Cazzolli et al., 2006; Zhang & Du, 2009). Wound closure is mediated in part by the interactions of the cortical actin cytoskeleton with the plasma membrane. Epub 2012 Jul 9. However, excessive force applied to the membrane can result in physical damage, such as the shear force applied on the endothelial cells by blood flow, on muscle cells during contraction, on lung alveolar cells during breathing, or by a blunt force trauma to any cell (Cong, Hubmayr, Li, & Zhao, 2017; Demonbreun & McNally, 2016; McNeil & Steinhardt, 2003).

Blauch LR, Gai Y, Khor JW, Sood P, Marshall WF, Tang SKY. For example, membrane shedding is a known mechanism of plasma membrane repair, which functions to limit the lateral expansion of the wound area (Andrews, Almeida, & Corrotte, 2014; Horn & Jaiswal, 2018). These enzymes initiate signaling through the generation of new lipid species, providing an added spatial, as well as a temporal component to lipid signaling, helping to more precisely coordinate the repair response. and transmitted securely. government site. Along with the annexins, which act quickly to physically manipulate the membrane itself, reassembly of the cytoskeleton plays a crucial role in restoring membrane tension in the later stages of repair. Individual lipids can serve as signaling molecules on their own or through binding proteins, and chemical changes to a single lipid can initiate change in local membrane composition. Sinha B, Kster D, Ruez R, Gonnord P, Bastiani M, Abankwa D, Johannes L (2011). Unlike sharks or alligators, for example, whose teeth are generally all the same size and shape, mammals have differently shaped teeth in different areas of the jaws to target specific foods or foraging strategies. Given their integral role in forming the structural backbone of the membrane, lipids are ideally placed to act as damage sensors, initiating early signaling that sets the stage for subsequent repair machinery. 2022 Dec 1;11(1):38. doi: 10.1186/s13619-022-00141-8.
