Abstract
BACKGROUND Phytosterol can improve its lipid solubility, lipophilic/hydrophilic balance and bioaccessibility by esterification with fatty acids, which increases its practical application range in the food industry. In the present study, small angle X-ray scattering combined with the pH-stat in vitro digestion model was applied to continuously monitor the molecular structure evolution of mixed micelles during digestion and investigate the effect of three edible oils (olive oil with 72.41 ± 0.57% oleic, sunflower seed oil with 63.45 ± 0.78% linoleic, refined linseed oil with 51.74 ± 0.34% linolenic) on bioaccessibility of stigmasterol oleate in vitro. RESULTS The release degree and rate of fatty acids in the three edible oil systems (kOO+ST-OA = 0.0501, kSO+ ST-OA = 0.0357, kLO+ST-OA = 0.0323) was compared. The three different edible oils had similar impact on the formation of dietary mixed micelles during the simulatedin vitro digestion of stigmasterol oleate, although there were significant differences in molecular morphology and composition of mixed micelles. The results showed that the vesicles formed by linoleic oil (SO system) or linolenic oil (LO system) were easy to dissociate. The largest average number and diameter of vesicles (5.55 × 1016 cm-3 and 2230.75 Å), the most stable vesicle structure and the fastest fatty acid release rate were observed in the OO system. CONCLUSION Compared to linoleic (SO system) or linolenic (LO system), the oleic (OO system) could facilitate the transformation of micelles to vesicles and maintain the stability of its membrane, significantly promotin the dissolution of stigmasterol and improving bioaccessibility. © 2023 Society of Chemical Industry.

Abstract
The main objective of this work was to investigate the uptake channels of skin cells through which coumarin 6, transported by deoxycholate-mediated liposomes (DOC-LS), was internalised; this was also compared against the action of conventional LS. Coumarin 6-loaded DOC-LS and LS were characterised for size distribution, zeta potential, and shape, and analysed in vitro in human epidermal immortal keratinocyte (HaCaT) (epidermal) and human embryonic skin fibroblast (CCC-ESF-1) (dermal) cell lines. Various endocytosis inhibitors were incubated with cells treated with the nanocarriers. Flow cytometry results indicated that HaCaT and CCC-ESF-1 cells internalise the tested preparations through pinocytotic vesicles, macropinocytosis, clathrin-mediated endocytic pathways, and via lysosomes, which consume a considerable amount of energy. The endocytosis pathways of DOC-LS and LS showed no difference. This study provides a basis for the application of LS being combined with a microneedle system for efficient intracellular drug delivery, targeting cutaneous histocyte disorders.

Neves MC, Filipe HAL, Reis RL, Prates Ramalho JP, Coreta-Gomes F, Moreno MJ, Loura LMS. Interaction of Bile Salts With Lipid Bilayers: An Atomistic Molecular Dynamics Study. Front Physiol 2019; 10:393. [PMID: 31024345 PMCID: PMC6465969 DOI: 10.3389/fphys.2019.00393] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Accepted: 03/21/2019] [Indexed: 01/10/2023] Open
Abstract
Bile salts (BS) are biosurfactants crucial for emulsification and intestinal absorption of cholesterol and other hydrophobic compounds such as vitamins and fatty acids. Interaction of BS with lipid bilayers is important for understanding their effects on membranes properties. The latter have relevance in passive diffusion processes through intestinal epithelium such as reabsorption of BS, as well as their degree of toxicity to intestinal flora and their potential applications in drug delivery. In this work, we used molecular dynamics simulations to address at the atomic scale the interactions of cholate, deoxycholate, and chenodeoxycholate, as well as their glycine conjugates with POPC bilayers. In this set of BS, variation of three structural aspects was addressed, namely conjugation with glycine, number and position of hydroxyl substituents, and ionization state. From atomistic simulations, the location and orientation of BS inside the bilayer, and their specific interactions with water and host lipid, such as hydrogen bonding and ion-pair formation, were studied in detail. Membrane properties were also investigated to obtain information on the degree of perturbation induced by the different BS. The results are described and related to a recent experimental study (Coreta-Gomes et al., 2015). Differences in macroscopic membrane partition thermodynamics and translocation kinetics are rationalized in terms of the distinct structures and atomic-scale behavior of the bile salt species. In particular, the faster translocation of cholate is explained by its higher degree of local membrane perturbation. On the other hand, the relatively high partition of the polar glycine conjugates is related to the longer and more flexible side chain, which allows simultaneous efficient solvation of the ionized carboxylate and deep insertion of the ring system.

Comparative performances of lactoferrin-loaded liposomes under in vitro adult and infant digestion models. Food Chem 2018; 258:366-373. [PMID: 29655747 DOI: 10.1016/j.foodchem.2018.03.070] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Revised: 02/24/2018] [Accepted: 03/17/2018] [Indexed: 11/22/2022]
Abstract
There remain gaps in our understanding of the fate of liposomes in the infant gastrointestinal tract, especially regarding essential proteins such as lactoferrin. Models in vitro that mirrored digestion in the stomach and intestine of infants and adults were used to explore the behaviour of lactoferrin-loaded liposomes. The liposomes behaved differently in these environments, with less hydrolysis of encapsulated lactoferrin under infant model conditions. Compared to the adult model (1000 ± 66 μM mL-1), fewer free fatty acids were released (500 ± 43 μM mL-1) from liposomal bilayers and there was less alteration in functional groups of phospholipids membranes, based on pH and FTIR after infant model digestion. Particle tracking analysis and TEM supported the reduced damage of particle structure under infant model conditions. This work provides information on the stability of functional protein-loaded liposomes during digestion, and shows the potential of liposomes to be nutrient carriers in infant foods.

Abstract
Context Besides their role in intestinal resorption of lipids, bile acids are regarded as endocrine and metabolic signaling molecules. The detailed profile of bile acid species in peripheral blood after an oral lipid tolerance test (OLTT) is unknown. Objective We quantified the regulation of 18 bile acids after OLTT in healthy individuals. Material and methods 100 volunteers were characterized by anthropometric and laboratory parameters and underwent OLTT. Venous blood was drawn in the fasted state (0 h) and at 2h, 4h, and 6 h after OLTT. Serum concentrations of 18 bile acids were measured by LC-MS/MS. Results All of the 6 taurine-conjugated bile acids (TUDCA, THDCA, TCA, TCDCA, TDCA, TLCA) and all of the 6 glycine-conjugated bile acids (GUDCA, GHDCA, GCA, GCDCA, GDCA, GLCA) rose significantly at 2h and remained elevated during OLTT. Of the primary bile acids, CA remained unchanged, whereas CDCA significantly decreased at 4h. Of the secondary bile acids, DCA, UDCA and HDCA were not altered, whereas LCA decreased. There was a significant positive correlation between the intestinal feed-back regulator of bile acid synthesis FGF-19 and bile acids. This correlation seems to depend on all of the six taurine-conjugated bile acids and on GCA, GDCA, and GCDCA. Females and users of hormonal contraception displayed higher levels of taurine-conjugated bile acids. Conclusions The novelty of the study is based on the identification of single bile acids during OLTT. LC-MS/MS-based quantification of bile acids in serum provides a reliable tool for future investigation of endocrine and metabolic effects of bile acids.
