cord-000884-zq8kqf6h	2013	This review will discuss the reconstitution of membrane protein activities in four different types of model membrane—monolayers, supported lipid bilayers, liposomes and nanodiscs, comparing their advantages in membrane protein reconstitution. To simplify cell membrane systems, model membranes such as monolayers, bilayers, liposomes and nanodiscs have been developed, enabling detailed investigation of membrane protein structure in lipid membranes. There are a number of approaches used to create a model membrane in order to mimic properties of the native cell membrane, and we will review these various approaches for reconstituting membrane proteins into different types of model membrane-monolayers [5] , supported planar lipid bilayer [6] and liposomes [7] as shown in Figure 1A -C. By using this approach, it appears that both PLA2 and PLC are active at the monolayer model membrane, indicating that the kinetics of phospholipid hydrolysis at the air-water interface can be monitored by biophysical characterization techniques in situ such as PM-IRRAS and infrared reflection adsorption spectroscopy [22] .

Continuing our studies of the effect of like-charged residues on protein-folding mechanisms, in this work, we investigated, by means of NMR spectroscopy and molecular-dynamics simulations, two short fragments of the human Pin1 WW domain [hPin1(14-24); hPin1(15-23)] and one single point mutation system derived from hPin1(14-24) in which the original charged residues were replaced with non-polar alanine residues.

cord-004584-bcw90f5b	2011	Our goals are two-fold: (1) to monitor conformational changes in each domain upon its binding to specific ligands and then to correlate the observed changes with structural differences between the CRDs and (2) to investigate the interaction between the CRDs and lipid model membranes. Cholesterol-assisted lipid and protein interactions such as the integration into lipid nanodomains are considered to play a functional part in a whole range of membrane-associated processes, but their direct and non-invasive observation in living cells is impeded by the resolution limit of [200nm of a conventional far-field optical microscope. Therefore, to investigate the dynamic and complex membrane lateral organization in living cells, we have developed an original approach based on molecule diffusion measurements performed by fluorescence correlation spectroscopy at different spatial scales (spot variable FCS, svFCS) (1).

The antigen is highly concentrated in the apical membrane of proximal tubule epithelial cells (600 gold particles/μm(2) of brush border membrane) whereas no labeling could be detected in other cell types or in other membranes of the same cells (basolatéral membranes, vacuoles or vesicles). Hybrids were selected in hypoxanthine, aminopterin and thymidine medium and superuatants from the culture wefts containing hybrid cells were tested for the presence of antibodies binding to the apical membrane of tubular epithelial cells on Torpedo kidney frozen sections.

Utilizing the procedure from Moore et al., OTO-CNMs Form I and Form II were synthesized and used in conjunction with cellulose triacetate (CTA) from Acros Organics (Fair Lawn, NJ, USA), N-methyl pyrrolidone (NMP) from VWR (Radnor, PA, USA), and deionized water to create novel membranes for filtration [21] . In this study on the implementation of two derivatives of cellulose nanomaterials into hollow fiber membranes for ultrafiltration and dialysis, OTO-CNM Form I and Form II mixed-matrix membranes have been quantitatively evaluated for the first time by determining model molecule selectivity (BSA, urea, and lysozyme), as well as transport rates (flux and diffusion rates).
cord-013223-f43hks44	2020	The increasing appreciation that microbiota-derived EV can enter the systemic circulation and be detected in human body fluids is likely to stimulate completely new areas of investigation in microbiome research, biomarkers and liquid biopsies, BEV-based therapeutics, onco-immunology, as well as fundamental microbial EV biology. In addition to potentially modulating the innate immune response via or more cytosolic DNA sensors, the possibility that pathogenic BEV-derived DNA can be transferred and detected in the nucleus of non-phagocytic cells (e.g. epithelial cells) [30] , raises the intriguing possibility that bacterial genetic material could be transferred to human somatic cells and integrated into the host genome. BEVs released by bacteria in the gut lumen can cross the epithelial barrier to gain access into the underlying submucosa enabling them to interact with various resident immune cell populations (dendritic cells, neutrophils and macrophages) as well as potentially disseminate more widely around the body via the systemic or lymphatic circulation to reach distant tissues and organs or even the brain (Fig. 2) .
cord-014685-ihh30q6f	2005	This study has attempted to analyse the structural properties of membrane peptides and proteins through the use of model systems that have been designed to mimic their natural counterparts: Podlubnaya 2 1 Institute of Theoretical and Experimental Biophysics RAS, 2 Pushchino State University Amyloid brils are formed by proteins or their peptides in the result of a conformational transition from alpha helix into beta-sheet structure. Analysis of the results of such studies indicate that folding of SNase fragments is dominated by developing the local and non-local nucleation sites from native-like secondary structures and by intensifying the longrange interactions of residues at nucleation sites with residues further removed in sequence. The results show that at different pH values the aggregation processes of both proteins follow different pathways determined by the variations in the native structure and by the details of the involved conformational changes.

Collagen can be fabricated into various forms of gel, fiber, membrane with or without pores, and it can even be grafted onto the non-viable metal, ceramic and synthetic biomaterials to introduce biological layer on surface. To produce an artificial skin, autologous dermal fibroblasts of rat were seeded into the EDC crosslinked porous collagen-laminin membrane and cultured in minimum essential medium (MEM) for 3 days to provide the cell-niche adaptation period. Although collagen based gel is favorable to fabricate cell conductive substitute, weak mechanical property is a barrier for application in the physiological stress bearing tissues, and, to resolve this problem, hybridization of collagen with polymeric biomaterials has been suggested.
cord-017566-dvxrwzqw	2005	During the infection of cells by animal viruses, membrane permeability is modified at two different steps of the virus life cycle (Carrasco, 1995) (Figure 6 .1). The viral molecules involved are components of virions: glycoproteins when enveloped particles are analyzed or, still unidentified, domains of the structural proteins in the case of naked viruses. At late times of infection, when there is active translation of late viral mRNAs, the plasma membrane becomes permeable to small molecules and ions (Carrasco, 1978) ( Figure 6 .1). Different viral molecules may be responsible for this late enhancement of membrane permeability, including viroporins (Gonzalez and Carrasco, 2003) , glycoproteins, and even proteases (Chang et al., 1999; Blanco et al., 2003) . Entry of enveloped animal viruses leads to early membrane permeabilization, which is mediated by the formation of the two pores (fusion and TM) formed by viral fusion glycoproteins.

Presence of receptors for the amino-terminal segments in target membranes has been suggested from studies on inhibition of virus replication by small peptides with amino acid sequences similar to that of the viral amino terminus (Richardson et al., 1980; Richardson and Choppin, 1983) . Why is a specific amino acid sequence of F glycoprotein required for the membrane fusion reaction between envelope of HVJ (Sendai virus) and target cell membranes? pH-Dependent membrane fusion activity of a synthetic twenty amino acid peptide with the same sequence as that of the hydrophobic segment in influenza virus hemagglutinin
cord-020714-h1fevqcw	2008	Other advantages of enveloped viruses in studies of membrane structure and biogenesis include the ease of biosynthetic labeling of viruses grown in cell culture with specific radioactive precursors and the availability of mutants in defined gene products, some of which are proving to be useful in the analysis of viral membrane assembly. Apart from minor differences in carbohydrates of glycoproteins, virion proteins are indistinguishable when the virus is propagated in a variety of cells; therefore there appears to be little or no determining influence of viral proteins on the composition of the lipid bilayer. Based upon the estimated carbohydrate content (12,000 daltons) of the HA glycoprotein obtained by Laver (1971) and Schwarz and Klenk (1974) and the size estimates of the type I and I1 glycopeptides of influenza virus grown in MDBK cells, it was estimated that HA, contains a single type I glycopeptide whereas HA, possesses two type I and one or two type I1 oligosaccharide side-chains for the WSN strain (Nakamura and Com pans, 1978b) .

cord-023200-3caevjvh	2018	The discovery of short, membrane interacting, amphipathic or hydrophobic sequences (known as membranotropic peptides) in both enveloped and non‐enveloped viruses suggests that these small peptides are strongly involved in breaching the host membrane and in the delivery of the viral genome into the host cell. [3, 4] The molecular details of the interactions at the interface of virus and cell surfaces are quite complex and highly variable, but there is a common idea that only a limited number of pathways allowing viruses to reach the sites of penetration exist, with enveloped and non-enveloped viruses presenting different and unrelated processes, but with general principles driving all fusion events. [16, 17] Viral fusion proteins undergo significant rearrangements from the pre-fusion to the post-fusion conformations which are triggered by either receptor binding, proteolytic cleavage or low endosomal pH, and eventually determine the exposure of previously sequestered hydrophobic peptides, loops, or patches, able to interact with and destabilize one or both the opposing membranes.

cord-030961-5gzc7193	2020	In the limit where bending dominates, for sufficiently large values of normalized bending stiffness, there is no adhesion between viral particles and the cell membrane without applied force. In this work, we create a continuum model for the small-deflection adhesive contact mechanics of virus particle attachment onto the host cell membrane in terms of the principal biophysical properties of the virus, membrane, and their interaction. These results also help to retrieve conditions for lack of adhesion, pull-off force, and contact area between the virus particle and cell membrane. We now describe in outline the continuum models for adhesive contact between the virus and cell membrane, driven by adhesion and external displacement or force, and resisted by tension and elastic bending. In our models, the parameters that govern the adhesive contact mechanics are (more in Table 1 ) bending rigid κ, tension σ, adhesion free energy per receptor β, binding receptor density ρ, and the radius of the virus, R.

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has gained popularity over the years as a ''bailout'' option after conventional circulatory support methods have proved refractory in the operating room (OR)/intensive care unit (ICU).

cord-103812-ls6zgipi	2020	Less is understood about their internalization, which forms double membrane vesicles containing cytosol and membranes from another cell, called connexosomes or annular gap junctions. Gap junction internalization can also be considered to be a form of trogocytosis (Joly and Hudriser, 2003) in which a portion of the plasma membrane and cytosol of the neighboring cell is transferred to the engulfing cell (See Fig. 1A ). Serial sections were then imaged to obtain threedimensional information; this distinguished between internalized connexosomes and gap junctions in the process of invagination. In 7 of the 56 modified connexosomes, a patch of unlabeled outer membrane bulged outward from a labeled inner membrane ( suggesting that different types of vesicles were involved.

To ad-dress the possibility that the mutant constructs analyzed in this study were mislocalized to the plasma membrane followed by rapid endocytic uptake to the vacuole, indirect immunofluorescence experiments were performed on BB-Inv, B-A-B, A20-BB, and/x22-AA-B expressed in a secl strain at 34~ As a positive control for accumulation in secretory vesicles, the localization of the fusion protein Fusl-LacZp was analyzed (Trueheart et al., 1987) .

cord-257754-pqxkyg8z	2006	In addition, a study analyzing conditional knock-out mice defective for autophagy has revealed that the mutant animal accumulates numerous ubiquitinated aggregates in the cytosol, suggesting that this covalent protein modification could serve to specifically target to autophagosomes large structures that have to be eliminated (Komatsu et al., 2005) . In contrast to mammalian cells where several isolation membranes can be simultaneously activated, a single perivacuolar site of organization for double-membrane vesicle formation (named the pre-autophagosomal structure, PAS) is observed in the yeast S. Because the three mammalian Atg8 homologs are diVerently expressed in various tissues (Tanida et al., 2004) , another intriguing option is that these proteins are involved in supplying the autophagosome with membranes derived from diVerent compartments depending on the cell type; for example, GATE-16 from the Golgi complex and GABARAP from the same organelle as well as the synaptic cisternae (Kittler et al., 2001; Kneussel et al., 2000; Sagiv et al., 2000) .

(41) The formation of a disulfide bond may also play a crucial role in the oligomerization of the E protein, forming stable dimers, trimers, and pentamers depending on its functional requirement.(105) Thus even though the TMD spans the lipid bilayer, the CxxC motif could serve as an essential key to defining the membrane-associated oligomerization events-providing newer targets for preemptive therapeutic intervention.

cord-272666-3uidpr79	2018	In this study, membrane rearrangements induced when expressing viral non-structural proteins (nsps) from two different strains of IBV were compared. In contrast to previously studied coronaviruses, IBV nsp4 alone is necessary and sufficient to induce membrane pairing; however, expression of the transmembrane proteins together was not sufficient to fully recapitulate DMVs. This indicates that although nsp4 is able to singularly induce membrane pairing, further viral or host factors are required in order to fully assemble IBV replicative structures. In a subsequent study by others, it was shown that expression of only nsp3 and 4 from either MERS-CoV or SARS-CoV was able to induce DMV formation, and furthermore, addition of nsp6 made no difference to their shape or size, and did not induce the spherule-like structures seen following infection with whole virus [26] .

cord-279463-bli8hwda	1986	As type II membrane proteins contain only a single stretch of hydrophobic amino acid residues, this might function as a signal for membrane insertion as well as a membrane anchor (Markoff et al., 1984; Spiess and Lodish, 1986) . plycat is an in-frame fusion between the 5'' region of ly encoding the cytoplas, mic, membrane-spanning segment plus 12 amino acids of the exoplasmic portion of ly and the gene encoding the cytoplasmic protein chloramphenicol acetyltransferase (CAT). After protease digestion in the presence of microsomal membranes, lyCAT* is reduced in molecular weight by about 2 kd, suggesting that it exposes 20-30 amino acid residues on the cytoplasmic side ( Figure 3 , lanes 2 and 3). This signal sequence is located in the amino-terminal half of the membrane-spanning segment, and it is cleaved when the preceding cytoplasmic domain is removed.
cord-284690-ogu1gmcb	2016	The use of viral vectors based on the tobacco mosaic virus (TMV) and potato virus X (PVX) for cloning and massively expressing AMP genes in Nicotiana benthamiana appears to be an interesting new approach to considerably enhance recombinant peptide production before structural and functional characterization. However, frequent gene silencing at the transcriptional level and instability of genes cloned in vectors for stable or transient expression remain major challenges limiting the efficient production of AMPs. Another persistent issue is the poor quality of the peptides endogenously synthesized in bacteria, yeast, and plants, particularly resulting from undesirable post-translational modifications [2, 33] . Some drawbacks presented by plant expression systems are solved by the CRISPR system, a revolutionary genome-editing technology that presents myriad possibilities for genetic manipulation at the genomic level and provides unprecedented tools (CRISPRi and CRISPRa) to precisely control gene expression and the structural modification of AMPs. Despite its current minor limitations (e.g. off-target effects), CRISPR could have a key role in the future development of clinical drugs as biotechnological antiinfective agents, including the rational biosynthesis of next-generation antimicrobials.

The present work reviews previous studies on the production and application of electrospun nanofibers as antimicrobial water filtration membranes. The objectives of this review were to: (i) introduce the different procedures, which have been applied for incorporation of the various antimicrobial agents into electrospun nanofibers (ii) discuss the different antimicrobial tests used for proving antimicrobial activity of the fabricated electrospun water filters (iii) study the efficiency of the produced antimicrobial electrospun application in the water treatment industry. Based on the majority of researches studied in this review, blending and post-modification strategies are two commonly used techniques to incorporate biocide agents into nanofibers aiming for water disinfection application (Shalaby et al., 2018; He et al., 2018; Makaremi et al., 2016) .
cord-287093-9mertwj7	2011	In this review, we discuss how three supergroups of (+)RNA viruses generate replication sites from membrane-bound organelles and highlight research on perinuclear factories induced by the nucleocytoplasmic large DNA viruses. In this review, we discuss how three supergroups of (+)strand RNA viruses generate replication sites from membrane-bound organelles and highlight research on perinuclear factories induced by the nucleocytoplasmic large DNA viruses (NCLDV). The RNA-dependent RNA polymerases (RdRp) of the (+)strand RNA viruses are targeted to the cytoplasmic face of membrane-bound organelles and subsequent assembly of the replicase complex induces membrane curvature and the formation of densely packed membrane vesicles (reviewed in [1, 2] ) ( Figure 1 ). This suggests that replication may take place on CM and that genomes are transferred to vesicular packets for envelopment and budding, while excess viral RNA may be stored in DMVs. Picornaviruses generate densely packed DMVs between 200 and 400 nm in diameter, a series of single membraned vesicles resulting from fragmentation of the Golgi, and autophagosomes possibly generated as a bystander response to infection [11 ,12-16] .
cord-289541-y7lewk1t	2006	The membrane is composed of three layers: two hydrophobic protective layers and a sandwiched hydrophilic support layer in which LiCl solution is immobilized to facilitate water vapor transfer. Further, the supported liquid layer only accounts for 12% of the total moisture transfer resistance in the cell, indicating that there is much potential for further performance improvement. The core material of an MTHR ventilator are vapor-permeable membranes, therefore both heat and moisture are transferred between these two air streams when they flow through the unit. However, moisture diffusion coefficients in such polymer membranes are usually very low, in the order of 10 −12 to 10 −13 m 2 s −1 [11, 18] , while MTHR ventilators only have limited transmembrane vapor partial pressure difference, consequently performances are quite limited currently. To improve the performances of MTHR ventilators, in this study, a novel membrane, a composite SLM, which employs LiCl liquid solution immobilized in a porous support membrane to facilitate the transport of moisture, is prepared.

In cells infected with TBEV, one of the most important tick-transmitted viruses in Europe and Asia, virus particles and membrane-connected vesicles were also observed inside the ER [25] , similar to what was described for DENV and WNV KUN .

cord-298019-gf2asni1	2014	While they have been initially discovered in viral fusion proteins and have been involved in the mechanism of viral entry, it is now clear that their features and their mode of interaction with membrane bilayers can be exploited to design viral inhibitors as well as to favor delivery of cargos across the cell membrane and across the blood–brain barrier. Peptides with a propensity for membrane binding can also interfere with enveloped virus entry by direct physical interaction with the hydrophobic surfaces present on cell membranes and/or fusion proteins. Since not all membranotropic peptides are able to cross the membrane bilayer, it is essential to identify structural characteristics of hydrophobic peptides know to enter the cell membrane to highlight any feature that is involved in the penetration which may help in the design of novel delivery tools.

cord-299270-fwbz3t25	2020	Abstract The field of membrane structural biology represents a fast-moving field with exciting developments including native nanodiscs that allow preparation of complexes of post-translationally modified proteins bound to biological lipids. Comparisons with the performance of conventional detergents suggests that the development of neutral or basic copolymers related to SMA could offer advantages, providing avenues for solubilization and analysis of a broader array of biological membrane:protein assemblies (memteins). The individual components of erythrocyte membranes including Rh proteins are well known, but their multimeric lipid complexes are dissociated in detergent-based preparations and hence no longer recognizable or extractable using conformation-specific antibodies. A set of ABCG2 protein constructs were designed with N-terminal GFP or SNAP and His 6 tags and solubilized from HEK cells using SMA(2:1) copolymer, as were CD28 and CD86 Antibiotics include lipid-specific peptides that self-associate into pores, which permeabilize bacterial membranes.

To extend these studies of membrane association of coronavirus replicase products, we analyzed the amino acid sequence of MHV-JHM nsp3 (from glycine-833 to glycine-2840) for probability of transmembrane helices using the five different programs designed to search for putative membrane-spanning sequences: Phobius, TMHMM, HMMTOP, SOSUI and TMpred (Fig. 2) . In contrast, when CMMs were added to the mixture, protein products that included all or part of nsp3-TM (PLP2-2485, -2390 and -2258) were detected predominantly in the pelleted fraction, consistent with membrane association (Fig. 3B ).
cord-309384-vlk8cebh	2012	A principal difference between ganglioside biosynthesis in the Golgi apparatus and degradation in the endolysosomal compartment is that during GSL formation, membranebound glycosyltransferases interact with their membranebound glycolipid substrates by diffusion within the twodimensional plane of the lipid bilayer. As glycosidase substrates, GSLs with four carbohydrate residues or less require the additional presence of small lipid binding glycoproteins, either the GM2 activator protein or one of the four saposins A-D. In vitro, in addition to enzymes and activator proteins, also an appropriate membrane-lipid composition of the ganglioside-containing membrane is required for degradation [222] . Due to the deficiency of two enzyme activities, β-hexosaminidases A and B, storage of negatively charged glycolipids characteristic for Tay-Sachs disease and, in addition, of uncharged substrates such as GA2 in the brain and globoside in visceral organs (Figure 16 ) is observed.

Therefore, strongly interconnected thin MPEG spider-web-like nano-nets with thick PA-6 nanofibers are responsible to increase mechanical strength and hydrophilic nature of PA-6 fibrous membranes, which make composite MPEG/PA-6 NFN membranes great potential in air filtration and different biomedical application. More recently, our group has presented continuous efforts toward the aim of generating PANI-based nanostructured materials and for the first time fabricated composite PANI/PA-6 NFN membranes (Fig. 20a) , which were used as a platform for efficient sensing reaction by providing high specific surface area and porosity.

CtBP1/BARS (C-terminal-binding protein-1/brefeldin A ribosylation substrate) proteins were originally demonstrated to regulate dynamin-independent fluid uptake in a variety of cell lines, and were later reported to localize to the site of and affect macropinosome membrane closure in a phosphorylation-dependent manner [36] . Overexpression of dominant negative, GTP-binding mutants of dynamin also blocked receptor-mediated endocytosis in various cells, suggesting a role for the GTPase activity of dynamin in the clathrin-dependent endocytic process outside the nervous system. The identification of an endocytic pathway as distinct has been primarily based on associated cargo proteins or lipids, and molecular regulators; the contribution of kinetics and detailed physical mechanism to such categorization is not generally available except in some wellcharacterized situations, namely clathrin-pit endocytosis or endocytosis by actin-dependent forces in yeast.

cord-336929-2rnkotqy	2012	In addition to the lipid components, a variety of cell receptors and signalling proteins are known to be associated with membrane rafts. Many animal viruses exploit the endocytic machinery of their host cell for infection, and lipid rafts are often a site for entry, assembly and budding of microbial pathogens, as confirmed by biochemical approaches and microscopy evidence (Kovbasnjuk et al., 2001; Suomalainen, 2002; Lu et al., 2008) . Interestingly, it had already been demonstrated that Brucella abortus infection is related with PrP C (cellular PrP), one of the lipid raft-associated molecules on the plasma membrane of different cell types. In the macrophage-like cell line RAW 264.7, for example, LPS stimulation induces translocation of CD14, ERK-2 (extracellular-signalregulated kinase 2) and p38 to lipid rafts, but other proteins also involved in the LPS signalling response do not migrate within these microdomains (Triantafilou et al., 2007; Olsson and Sundler, 2006) .

At pH 7.4, the terminal α-carboxylic acid in the side chain is deprotonated and ionized; this would be repelled from the cell membrane, but, because of strong hydrophobic interactions, indole in the side chain can attract and intercalate into phospholipids, generating PMLA tritryptophan-lipid complexes and releasing binding energy to stabilize the structure. To increase the interaction between the biopolymer and the plasma membrane, methylation of carboxylic acid groups with different levels of diazomethane was used to generate a PMLA-Me x H 100−x copolymer (where x is the percentage of methyl units) [77, 78] .

Tryptophan (Trp), as a non-polar amino acid, has a remarkable effect on the interface region of the lipid bilayer, whereas Arg, as a basic amino acid, confers peptide charge and hydrogen bond interactions, which are essential properties to combine with the bacterial membrane''s abundant anionic component. And it seems that Trp residues play the role of natural aromatic activators of Arg-rich AMPs by ion-pair-π interactions (Walrant et al., 2020) , thereby promoting enhanced peptide-membrane interactions (Chan et al., 2006) . Furthermore, L4H4, which is designed based on the linear cationic amphiphilic peptide magainin, also shows good antibacterial activity and cell penetration properties by inserting four histidine sequences in leucine and alanine (Lointier et al., 2020) .
