Abstract
In mammals, polysialic acid (polySia) attached to a small number of transmembrane protein carriers occurs on the surface of plasma membranes of neural, cancer, immune, and placental trophoblast cells. Here, our goal was to demonstrate the presence of polySia on exosomes and its effect on membrane properties. We isolated exosomes and found that polysialylated exosomes in fetal bovine serum originate mostly from placental trophoblasts, while in calf bovine serum, they originate from immune cells. Enzymatic removal of polySia chains from the exosomal surface makes the membrane surface potential more positive, transmembrane potential more negative, and reduces the activation energy for membrane anisotropy changes. We demonstrate for the first time that exosomes could interact through polySia-raft interactions. We suggest that polysialylation of exosomal membrane can have a thermo-protecting effect and can modulate exosome-plasma membrane interactions.

Molecules 2020; 25:molecules25081801. [PMID: 32295310 PMCID: PMC7221546 DOI: 10.3390/molecules25081801] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/07/2020] [Accepted: 04/08/2020] [Indexed: 01/26/2023] Open
Abstract
The needles of conifer trees are one of the richest sources of natural polyprenols. Polyprenol homologs from Abies sibirica L. lipophilic 80% purified extract were analyzed and quantified. In total, 10 peaks (Prenol-11 to Prenol-20) were observed in the ultra-high-performance liquid chromatography–diode array detector (UHPLC-DAD) chromatogram of Siberian fir with the most abundant compound being Prenol-15 (relative amount 37.23 + 0.56% of the total polyprenol yield). Abies sibirica L. polyprenol solubility and incorporation efficiency into liposomes were studied in various commercially available lecithin mixtures (Phosal IP40, Phosal 75SA, and Lipoid P45). The resulting multilamellar polyprenol liposomes were morphologically characterized by Light and Transmission Electron Microscopy, and the liposome size was discovered to be polymodal with the main peak at 1360 nm (90% of the volume). As polyprenols are fully soluble only in lipids, a liposomal formulation based upon co-solubilization and a modified ethanol injection method of polyprenols into the ethanol-phospholipid system was developed for the entrapment and delivery of polyprenols for potential commercial applications in food supplement and cosmetic industries.

Abstract
Mono-saturated polyprenols (dolichols) have been found in almost all Eukaryotic cells, however, dolichols containing additional saturated bonds at the ω-end, have been identified in A. fumigatus and A. niger. Here we confirm using an LC-ESI-QTOF-MS analysis, that poly-saturated dolichols are abundant in other filamentous fungi, Trichoderma reesei, A. nidulans and Neurospora crassa, while the yeast Saccharomyces cerevisiae only contains the typical mono-saturated dolichols. We also show, using differential scanning calorimetry (DSC) and fluorescence anisotropy of 1,6-diphenyl-l,3,5-hexatriene (DPH) that the structure of dolichols modulates the properties of membranes and affects the functioning of dolichyl diphosphate mannose synthase (DPMS). The activity of this enzyme from T. reesei and S. cerevisiae was strongly affected by the structure of dolichols. Additionally, the structure of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) model membranes was more strongly disturbed by the poly-saturated dolichols from Trichoderma than by the mono-saturated dolichols from yeast. By comparing the lipidome of filamentous fungi with that from S. cerevisiae, we revealed significant differences in the PC/PE ratio and fatty acids composition. Filamentous fungi differ from S. cerevisiae in the lipid composition of their membranes and the structure of dolichols. The structure of dolichols profoundly affects the functioning of dolichol-dependent enzyme, DPMS.

Abstract
Polysialic acid (polySia) is expressed on the surface of neural cells, neuroinvasive bacterial cells and several tumor cells. PolySia chains attached to NCAM can influence both trans interactions between membranes of two cells and cis interactions. Here, we report on the involvement of phospholipids in regulation of membrane interactions by polySia. The pH at the surface of liposomes, specific molecular area of phosphatidylcholine molecules, phase transition of DPPC bilayers, cyclic voltammograms of BLMs, and electron micrographs of phosphatidylcholine vesicles were studied after addition of polysialic acid free in solution. The results indicate that polySia chains can associate with phosphatidylcholine bilayers, incorporate into the polar part of a phospholipid monolayer, modulate cis interactions between phosphatidylcholine molecules, and facilitate trans interactions between apposing phospholipid vesicles. These observations imply that polySia attached to NCAM or to lipids can behave similarly.

Abstract
The analysis of polyion transmembrane translocation was performed using membrane electrical equivalent circuit. The dependence of polyion flux across membranes on time, membrane electrical conductance, membrane electrical capacitance, degree of polymerization, water solution conductance and applied transmembrane potential is discussed. The changes in polyion flux were up to 88% after 1 ms. Both the increase of polyion chain length and the decrease of membrane conductance resulted in the diminution of this effect. Inversion of flux direction was observed as a result of external potential changes. Reversal curves, representing the values of considered parameters for zero-flux were also shown. The replacement of a polyanion by a polycation of the same chain length resulted in the same shape of the surface plot but with opposite orientation. The analysis describes the effect of transmembrane potential on the translocation rate of polyanionic polysialic acid and polynucleotides, and polycationic peptides across membranes.

Abstract
The electrical measurements of phospholipid bilayers and the studies of phospholipid vesicles by using the transmission electron microscopy (TEM) showed that dotriacontaprenol (C(160)) isolated from leaves of Spermatophyta influences some properties of membranes. The current-voltage characteristics, the membrane conductance-temperature relationships, the membrane breakdown voltage and the membrane capacitance have been measured for different mixtures of C(160)/DOPC. The membrane conductance, the activation energy of ion migration across the membrane and the membrane thickness were determined. Dotriacontaprenol decreases the membrane breakdown voltage, the activation energy and the membrane capacitance, and increases the membrane conductance and the membrane hydrophobic thickness. The analysis of TEM micrographs shows several characteristic structures, which have been described. The results indicate that dotriacontaprenol increases the membrane elasticity and modulates the surface curvature of the membranes by the formation of fluid microdomains. We suggest that the long polyprenols facilitate the formation of transmembrane, ions-conductive pores.

Abstract
In the present study we investigated phospholipid bilayer membranes and phospholipid vesicles made from dioleoylphosphatidylcholine (DOPC) or its mixture with the phosphate ester derivative of long-chain polyprenol (hexadecaprenyl diphosphate, C(80)-PP) by electrophysiological and transmission electron microscopy (TEM) techniques. The membrane conductance-temperature relationships and the membrane breakdown voltage have been measured for different mixtures of C(80)-PP/DOPC. The current-voltage characteristics, the membrane conductance, the activation energy of ion migration across the membrane and the membrane breakdown voltage were determined. Hexadecaprenyl diphosphate decreases the membrane conductance, increases the activation energy and the membrane breakdown voltage for the various values of C(80)-PP/DOPC mole ratio. The analysis of TEM micrographs shows several characteristic structures, which have been described. The data indicate that hexadecaprenyl diphosphate modulates the surface curvature of the membranes by the formation of aggregates in liquid-crystalline phospholipid membranes. The properties of modified membranes can result from the presence of the negative charges in the hydrophilic part of C(80)-PP molecules and can be modulated by the concentration of this compound in membranes. We suggest that the dynamics and conformation of hexadecaprenyl diphosphate in membranes depend on the transmembrane electrical potential.

Abstract
The effect of undecaprenyl phosphate (C55-P) on dioleoylphosphatidylcholine (DOPC) bilayer lipid membranes has been studied. The current-voltage characteristics, steady-state diffusion potentials, membrane conductance-temperature relationships, membrane electric capacitance and membrane breakdown voltage have been measured for different mixtures of undecaprenyl phosphate and DOPC. The ratio of permeability coefficients for sodium and chloride ions, the activation energy for ion migration across the membrane and membrane thickness have been determined. The electrical measurements showed that undecaprenyl phosphate decreases membrane-normalized conductance, membrane ionic permeability, membrane hydrophobic thickness and membrane selectivity for chloride ions, and increases the activation energy for ion transport, membrane nonlinearity potential, membrane specific capacitance, membrane electromechanical stability and membrane selectivity for sodium ions. From the results, we suggest that the interaction of the gradient of electric transmembrane potential with the negative charge of the phosphate group of C55-P determines the dynamics, conformation and aggregation behaviour of undecaprenyl phosphate in phospholipid membranes. Some implications of these findings for a possible regulation of the C55-P-dependent expression of polysialic acid capsule in Escherichia coli K1 bacterial cells are indicated.

Abstract
The peptidoglycan layer of bacterial cell walls is biosynthesised using a lipid carrier undecaprenyl phosphate to assemble and transport the MurNAc(GlcNAc)-pentapeptide precursor. Similar lipid-linked cycles are involved in the biosynthesis of other bacterial exopolysaccharides and eukaryotic asparagine-linked glycoproteins, the latter involving the structurally related dolichyl phosphate as a lipid carrier. Recent protein sequence data and common inhibitors of the bacterial and eukaryotic systems have revealed functional similarities between the two systems. Biological and physical studies on the lipid carriers themselves have provided clues to their role in oligosaccharide translocation, but have not revealed significant differences in function between undecaprenyl phosphate and dolichyl phosphate. The presence of dolichyl phosphate and a family of saturated isoprenoid lipids in Archaebacteria suggests a possible evolutionary link between the two systems.
