Abstract
Free fatty acids, like palmitic acid (PA), and xanthophyll pigments, like lutein (LUT) are the natural membrane compounds in plants. To study the effect of PA on LUT and their organization, a model membrane of 1,2-dimyristoyl-sn-glycerol-3-phosphocholine (DMPC) enriched with 2 mol% PA and 1 mol% LUT was formed. Molecular mechanisms underlying the interaction between these two compounds were examined with application of molecular spectroscopy techniques, e.g., visible spectroscopy, electron paramagnetic resonance and Fourier transform infrared. We determined the monomeric/dimeric organization of LUT in the membrane. We proved that the presence of PA in the lipid phase facilitated and stabilized the formation of LUT structures in the membrane. Lutein with PA did not form strong molecular aggregates like H- and J-structures. We presented the simplified model membrane that could be a suitable representation of the physiological process of de-esterification of PA from LUT appearing in natural biomembranes in humans.

Abstract
Food contamination with pathogenic microorganisms, such as Listeria monocytogenes, Salmonella enterica, Staphylococcus aureus and Bacillus cereus, is a common health concern. Natural products, which have been the main source of antimicrobials for centuries, may represent a turning point in alleviating the antibiotic crisis, and plant polyphenolic compounds are considered a promising source for new antibacterial agents. Resveratrol and resveratrol-derived monomers and oligomers (stilbenoids) have been shown to exert a variegated pattern of efficacy as antimicrobials depending on both the polyphenols' structure and the nature of the microorganisms, and the bacterial cell membrane seems to be one of their primary targets.In this scenario and based on the thermodynamic information reported in the literature about cell membranes, this study aimed at the investigation of the direct interaction of selected stilbenoids with a simple but informative model cell membrane. Three complete stilbenoid "monomer/dimer/dehydro-dimer" sets were chosen according to different geometries and substitution patterns. Micro-DSC was performed on 2 : 3 DPPC : DSPC small unilamellar vesicles with incorporated polyphenols at physiological pH and the results were integrated using complementary NMR data. The study highlighted the molecular determinants and mechanisms involved in the stilbenoid-membrane interaction, and the results were well correlated with the microbiological evidence previously assessed.

Abstract
The influence of free fatty acids (FFAs) on the nisin-membrane interaction was investigated through micro-DSC and fluorescence spectroscopy. A simple but informative model membrane was prepared (5.7 DMPC:3.8 DPPS:0.5 DOPC molar ratio) by considering the presence of different phospholipid headgroups in charge and size and different phospholipid tails in length and unsaturation level, allowing the discrimination of the combined interaction of nisin and FFAs with the single phospholipid constituents. The effects of six FFAs on membrane stability were evaluated, namely two saturated FFAs (palmitic acid and stearic acid), two monounsaturated FFAs (cis-unsaturated oleic acid and trans-unsaturated elaidic acid) and two cis-polyunsaturated FFAs (ω-6 linoleic acid and ω-3 docosahexaenoic acid). The results permitted assessment of a thermodynamic picture of such interactions which indicates that the peptide-membrane interaction does not overlook the presence of FFAs within the lipid bilayer since both FFAs and nisin are able to selectively promote thermodynamic phase separations as well as a general lipid reorganization within the host membrane. Furthermore, the magnitude of the effects may be different depending on the FFA chemical structure as well as the membrane lipid composition.

Lipid Modulation in the Formation of β-Sheet Structures. Implications for De Novo Design of Human Islet Amyloid Polypeptide and the Impact on β-Cell Homeostasis. Biomolecules 2020; 10:biom10091201. [PMID: 32824918 PMCID: PMC7563882 DOI: 10.3390/biom10091201] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 08/03/2020] [Accepted: 08/04/2020] [Indexed: 12/25/2022] Open
Abstract
Human islet amyloid polypeptide (hIAPP) corresponds to a 37-residue hormone present in insulin granules that maintains a high propensity to form β-sheet structures during co-secretion with insulin. Previously, employing a biomimetic approach, we proposed a panel of optimized IAPP sequences with only one residue substitution that shows the capability to reduce amyloidogenesis. Taking into account that specific membrane lipids have been considered as a key factor in the induction of cytotoxicity, in this study, following the same design strategy, we characterize the effect of a series of lipids upon several polypeptide domains that show the highest aggregation propensity. The characterization of the C-native segment of hIAPP (residues F23-Y37), together with novel variants F23R and I26A allowed us to demonstrate an effect upon the formation of β-sheet structures. Our results suggest that zwitterionic phospholipids promote adsorption of the C-native segments at the lipid-interface and β-sheet formation with the exception of the F23R variant. Moreover, the presence of cholesterol did not modify this behavior, and the β-sheet structural transitions were not registered when the N-terminal domain of hIAPP (K1-S20) was characterized. Considering that insulin granules are enriched in phosphatidylserine (PS), the property of lipid vesicles containing negatively charged lipids was also evaluated. We found that these types of lipids promote β-sheet conformational transitions in both the C-native segment and the new variants. Furthermore, these PS/peptides arrangements are internalized in Langerhans islet β-cells, localized in the endoplasmic reticulum, and trigger critical pathways such as unfolded protein response (UPR), affecting insulin secretion. Since this phenomenon was associated with the presence of cytotoxicity on Langerhans islet β-cells, it can be concluded that the anionic lipid environment and degree of solvation are critical conditions for the stability of segments with the propensity to form β-sheet structures, a situation that will eventually affect the structural characteristics and stability of IAPP within insulin granules, thus modifying the insulin secretion.

Abstract
A fifteen-components model membrane that reflected the 80 % of phospholipids present in Insulin Secretory Granules was obtained and thermodynamic exploitation was performed, through micro-DSC, in order to assess the synergic contributions to the stability of a mixed complex system very close to real membranes. Simpler systems were also stepwise investigated, to complete a previous preliminary study and to highlight a hierarchy of interactions that can be now summarized as phospholipid tail unsaturation > phospholipid tail length > phospholipid headgroup > membrane curvature. In particular, Small Unilamellar Vesicles (SUVs) that consisted in phospholipids with different headgroups (choline, ethanolamine and serine), was step by step considered, following inclusion of sphingomyelins and lysophosphatidylcholines together with a more complete fatty acids distribution characterizing the phospholipid bilayer of the Insulin Secretory Granules. The inclusion of cholesterol was finally considered and the influence of three FFAs (stearic, oleic and elaidic acids) was investigated in comparison with simpler systems, highlighting the magnitude of the effects on such a detailed membrane in the frame of Type 2 Diabetes Mellitus alterations.

Abstract
The utilization of liposomes in biomedical applications has greatly benefited the diagnosis and treatment of various diseases. These biomimetic nano-entities have been very useful in the clinical practice as drug delivery systems in their conventional form, comprising lipids as structural components. However, the scientific efforts have recently shifted towards the development of more sophisticated nanotechnological platforms, which apply functional biomaterials, such as stimuli-responsive polymers, in order to aid the drug molecule targeting concept. These nanosystems are defined as chimeric/mixed, because they combine more than one different in nature biomaterials and their development requires intensive study through biophysical and thermodynamic approaches before they may reach in vivo application. Herein, we designed and developed chimeric liposomes, composed of a phospholipid and pH-responsive amphiphilic diblock copolymers and studied their morphology and behavior based on crucial formulation parameters, including biomaterial concentration, dispersion medium pH and polymer composition. Additionally, their interactions with biological components, pH-responsiveness and membrane thermodynamics were assessed. Finally, preliminary in vivo toxicity experiments of the developed nanosystems were carried out, in order to establish a future protocol for full in vivo evaluation. The results have been correlated with the properties of the chimeric nanosystems and highlight the importance of such approaches for designing and developing effective nanocarriers for biomedical applications.
