Glycerol-3-phosphate is used to generate PA as well as PG through the intermediate phosphatidylglycerol phosphate (PGP). Injury to the plasma membrane also changes the biochemical environment within the cell. Bouter A, Gounou C, Brat R, Tan S, Gallois B, Granier T, Brisson AR. The long held dogma in the cardiac biology community was that these cells do not . It also works extracellularly to improve repair of injured muscle and other cells (Gushchina et al., 2017; Weisleder et al., 2012). Nojima H, Freeman CM, Gulbins E, & Lentsch AB (2015).

Idone V, Tam C, Goss JW, Toomre D, Pypaert M, & Andrews NW (2008). Each of these provides another mechanism for generating specific membrane lipids acutely in parallel to biosynthetic inputs. Membranes Self-repair Biological Strategy AskNature Palmitate-mediated disruption of the endoplasmic reticulum decreases intracellular vesicle motility. Why does our body heal itself? However, in addition to this role, restoring membrane tension is another role that has been proposed for endocytosis after the membrane is resealed following a pore forming toxin injury (Skalman, Holst, Larsson, & Lundmark, 2018). 2022 Aug 23;13(1):4950. doi: 10.1038/s41467-022-31277-5. PKC, in turn, influences a wide variety of downstream pathways known to facilitate repair including vesicle fusion, Rho GTPase patterning, as well as repair potentiation (Togo, 2004; Vaughan et al., 2014; Zuzek et al., 2013). Middel V, Zhou L, Takamiya M, Beil T, Shahid M, Roostalu U, Nienhaus GU (2016). Membrane-stabilizing copolymers confer marked protection to dystrophic skeletal muscle in vivo, Molecular Therapy-Methods & Clinical Development. Instead, there exists distinct inter- and intra-leaflet heterogeneity of lipids. The goal of signaling during plasma membrane repair is to generate a polarized response such that the repair machinery can be spatially and temporally localized and activated at the repair site. Drescher DG, Drescher MJ, Selvakumar D, Annam NP. The physical properties of the plasma membrane are governed in large part by the effect of lipid interactions at the population level. This can limit the expansion of the wound area itself. Muscle fibers have a complex plasma membrane network with a repeating register of deep plasma membrane invaginations called the t-tubule network. As discussed above, sphingolipids in the plasma membrane are an important regulator of plasma membrane repair. 'Resealing' is the emergency response required for cell . This is especially important in sensing membrane damage. Semin Cell Dev Biol. Annexin A1 deficiency does not affect myofiber repair but delays regeneration of injured muscles. While lipids are often ascribed a metabolic role as energy storage molecules, they also play important structural and signaling roles in the cell. This signaling function may occur due to the activity of the repair protein EHD2, which accumulates at the site of membrane injury and is thought to play a role in shaping membrane dynamics (Daumke et al., 2007; Demonbreun et al., 2016; Marg et al., 2012). Thus, each of these lipids contributes significantly to the organization, structure, and function of the plasma membrane as a whole. Gauthier NC, Masters TA, & Sheetz MP (2012). These observations suggest that lipids are not bystanders during the repair process, but are instead actively involved in organizing the playing field on which repair machinery operates. Influx of calcium from the extracellular space, as well as locally increased oxidation, both trigger lipid signaling that is required for repair. Microfluidic guillotine reveals multiple timescales and mechanical modes of wound response in Stentor coeruleus. official website and that any information you provide is encrypted Use of lipidomics during epidermal wound repair identified that several of the plasma membrane lipids discussed above are enriched during wound repair. The .gov means its official. Dysferlin regulates cell membrane repair by facilitating injury-triggered acid sphingomyelinase secretion, Demonbreun AR, & McNally EM (2016). The role of lipids during plasma membrane repair goes far beyond a passive role in vesicle-mediated delivery of membrane lipids. Corrotte M, Almeida PE, Tam C, Castro-Gomes T, Fernandes MC, Millis BA, Maugel TK.

Sphingosine 1-phosphate stimulates proliferation and migration of satellite cells: role of S1P receptors, Biochimica et Biophysica Acta (BBA)-Molecular Cell Research. For example, venomous snakes store precursor molecules to instantly synthesize a suite of toxins via enzyme-mediated cascades. In mammalian cells, lipids formed upon the phosphate and glycerol (e.g. (2017). As lipids comprise the bulk of the plasma membrane, the acts of injury, resealing, and remodeling all directly impinge upon the plasma membrane lipids. For example, the dynamic arrangement of lipids in the plasma membrane as discussed above, and the electrostatic or chemical changes in lipids due to enzymatic activity of lipid modifying enzymes rapidly affect lipids themselves as well as the target proteins in the plasma membrane (Figure 2B, ,C).C). Bacterial pore-forming toxins oligomerize and insert in the plasma membrane of target cells forming a diffusible pore. This allows for the movement and patterning of lipids into signaling domains, changing the spatial arrangement of proteins that selectively interact with a particular lipid species. HHS Vulnerability Disclosure, Help This results in the replacement of half of the body's adipocytes in 8 years. 8600 Rockville Pike We here review what is known about the cellular and molecular mechanisms of membrane repair, with particular emphasis on the relevance of repair as it relates to disease pathologies. Self-repairing cells: How single cells heal membrane ruptures and As MG53 interacts with the plasma membrane in a cholesterol-dependent manner ((Zhu et al., 2012); see Section 4), its extracellular role may involve a mode of action similar to poloxamer 188, where it inserts within membranes in a disordered lipid environment. 8600 Rockville Pike Quantification of membrane tension after injury to fibroblasts demonstrated that a minimum tension force was reached by approximately 30 seconds post-injury, but tension was fully restored by 80 seconds post-injury (Togo et al., 2000). This cytoskeletal assembly is regulated by Rho GTPase activity, which triggers F-actin accumulation at the site of injury. We have briefly discussed how such an integral role of lipids in plasma membrane repair also extends into tissue-level repair and restoration of organ function. Instead, distinct inter- and intra-leaflet heterogeneity exists. Copyright 2017, American Association for the Advancement of Science. This dissociation has the effect of allowing Rho GTPase translocation to the membrane where it can interact with signaling lipids. Stem cells in animal models of regeneration. At each of these levels the structural and signaling aspects of lipids are critical for the cell to mount an efficient response to plasma membrane injury. Plasma membrane lipids are routinely interconverted as a means to maintain lipid homeostasis and for lipid-mediated signaling. These functions also require modulating the membrane area, such as through the processes of exocytosis and endocytosis or by changing the existing membrane architecture (Kozlov & Chernomordik, 2015; Nassoy & Lamaze, 2012). Federal government websites often end in .gov or .mil. Many organisms and tissues display the ability to heal and regenerate as needed for normal physiology and as a result of pathogenesis. 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). Very large plasma membrane disruptions (micron diameter) require membrane patching. One such mechanism is addition of more membrane via vesicle fusion (Fig 1B ). Therefore, injury-triggered protein-lipid interactions that result in modified lipids generates signaling that allows for changes in activity and localization of plasma membrane repair machinery. Not only is the composition and organization of the plasma membrane in constant flux, the membrane itself also must interact with forces being applied to it from all directions. doi: 10.1016/j.cub.2017.12.034. Cholesterol modulates cell signaling and protein networking by specifically interacting with PDZ domain-containing scaffold proteins. Self-repairing cells: How single cells heal membrane ruptures and Along with DAG, IP3 is also generated by the activity of PLC. cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. See this image and copyright information in PMC. This is in part achieved through the activity of lipid modifying enzymes, such as kinases, phosphatases, and phospholipases. Godin LM, Vergen J, Prakash Y, Pagano RE, & Hubmayr RD (2011). Endocytosis can also occur at sites of membrane invagination known as caveolae, and caveolae internalization has been implicated in membrane repair (Corrotte et al., 2013). However, to successfully repair the cell also needs to restore the barrier function of the resealed membrane. 2015 Sep;45:2-9. doi: 10.1016/j.semcdb.2015.09.023. Cells respond to mechanical stress by rapid disassembly of caveolae. They consist of a variety of lipid mediators derived from the omega-3 essential fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and include lipoxins, resolvins and protectins. Compared with cytosolic antioxidants, which can be detrimental to repair (Spaeth et al., 2012), vitamin E is membrane-localized and could therefore allow for the local buildup of oxidized lipids at the site of injury while preventing the global spread of lipid oxidation. Liquids, mostly water, make up 70 to 90% of all living systems, and the loss of even a small percentage can mean the difference between life and death. Thus, while increase in lipid mobility following plasma membrane injury is associated with successful repair, excessive lipid mobility leading to membrane instability is detrimental to the repair process. Lipids also interact with plasma membrane localized proteins to regulate membrane tension and fluidity. Membrane Repair: Mechanisms and Pathophysiology - PubMed 2018 Apr 23;28(8):R392-R397. Minetti C, Sotgia F, Bruno C, Scartezzini P, Broda P, Bado M, Donati MA (1998). By direct imaging of skeletal myofibers during the course of repair from a focal injury, exposure of PS on the injured myofiber surface was found to attract macrophages to the injury site. We use cookies to give you the best browsing experience. Sreetama SC, Chandra G, Van der Meulen JH, Ahmad MM, Suzuki P, Bhuvanendran S, Jaiswal JK (2018). Before This Goldilocks principle applies to several aspects of lipid involvement in the repair process. Thus, local lipid peroxidation may provide transient membrane stabilization, while mechanisms such as redox-dependent MG53 binding may limit the spread of lipid peroxides. These examples illustrate the far-reaching consequence of lipid movement on structural stability of the plasma membrane and its ability to successfully repair. Heier CR, Damsker JM, Yu Q, Dillingham BC, Huynh T, Van der Meulen JH, Scheffer L. (2013). In fact, cells are able to perform hundreds, even thousands, of chemical transformations at the same time under life-friendly conditions (ambient temperature and pressure in an aqueous environment). PIP2 accumulation was observed as early as 4 seconds in mouse myofibers; however, it continued to accumulate even 1 minute post-injury suggesting a role in the later stages of repair (Demonbreun et al., 2016). Saarikangas J, Zhao H, & Lappalainen P (2010). Cholesterol and various proteins are also embedded within the . Role of phosphatidylinositol 4, 5-bisphosphate in regulating EHD2 plasma membrane localization. These mediators promote wound resolution by acting upon the immune and endothelial cells and help to control the duration and nature of the immune and phagocytic cell infiltration at the injury site (Serhan, 2014).
