Abstract
Procyanidins are bioactive compounds present in fruits like apples. These compounds can be extracted and studied for their functional properties. Within the class of procyanidins, procyanidin B2 (PB2) serves as a standard reference. Sake, a traditional Japanese alcoholic beverage, contains ethyl caproate (EC), which adds economic value to the drink. Analyzing PB2 in apple juice and EC in sake, particularly in simple prepared beverages without the use of organic solvents or in their original state, requires the application of binary liposomes composed of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC). In this study, I investigated the size of liposomes and the ratio of solid ordered (So) to liquid disordered (Ld) liposomes. The results indicated that PB2 increased the size of liposomes, while EC decreased it. Additionally, EC influenced the ratio of So/Ld liposomes. These findings provide a foundational understanding for further research on the biophysical and physiological properties of EC and PB2.

Yoda T. Charged Lipids Influence Phase Separation in Cell-Sized Liposomes Containing Cholesterol or Ergosterol. MEMBRANES 2022; 12:membranes12111121. [PMID: 36363676 PMCID: PMC9697951 DOI: 10.3390/membranes12111121] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 11/06/2022] [Accepted: 11/07/2022] [Indexed: 05/14/2023]
Abstract
Positively charged ion species and charged lipids play specific roles in biochemical processes, especially those involving cell membranes. The cell membrane and phase separation domains are attractive research targets to study signal transduction. The phase separation structure and functions of cell-sized liposomes containing charged lipids and cholesterol have been investigated earlier, and the domain structure has also been studied in a membrane model, containing the yeast sterol ergosterol. The present study investigates phase-separated domain structure alterations in membranes containing charged lipids when cholesterol is substituted with ergosterol. This study finds that ergosterol increases the homogeneity of membranes containing charged lipids. Cholesterol-containing membranes are more sensitive to a charged state, and ergosterol-containing liposomes show lower responses to charged lipids. These findings may improve our understanding of the differences in both yeast and mammalian cells, as well as the interactions of proteins with lipids during signal transduction.

Poult Sci 2022; 102:102238. [PMID: 36368171 PMCID: PMC9650060 DOI: 10.1016/j.psj.2022.102238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 10/05/2022] [Accepted: 10/05/2022] [Indexed: 11/06/2022] Open
Abstract
The purpose of this study was to formulate tee tree oil nanoliposomes (TTONL) and evaluate its characterization and antibacterial activity. TTONL was prepared by thin film hydration and sonication technique, and the preparation conditions were optimized by Box-behnken response surface method. The characterization (morphology, size, zeta potential, and stability) and antibacterial activity of TTONL against Escherichia coli (E. coli) in vitro and in vivo were evaluated. The optimal preparation conditions for TTONL: lecithin to cholesterol mass ratio of 3.7:1, TTO concentration of 0.5%, and pH of the hydration medium of 7.4, which resulted in a TTONL encapsulation rate of 80.31 ± 0.56%. TTONL was nearly spherical in shape and uniform in size, and the average particle size was 227.8 ± 25.3 nm with negative charge. The specific disappearance of the TTO peak in the infrared spectrum suggested the successful preparation of TTONL, which showed high stability at 4°C within 35 d. The result of MIC test found that the nanoliposomes improved antibacterial activity of TTO against various E. coli strains. TTONL exposure in vitro caused different degrees of structural damage to the E. coli. TTONL by oral administration alleviated the clinical symptoms and intestinal lesion of chickens induced with E. coli challenge. Furthermore, TTONL treatment remarkably lowered the mRNA expression of NLRP3 and NF-κB (p65) in the duodenum and cecum of E. coli-infected chickens. In conclusion, the prepared TTONL had good stability and slow-release property with dose-dependent inhibition and killing effects on different strains of E. coli, and exerted a preventive role against chicken colibacillosis through inhibition.

Yoda T, Saito T. Size of Cells and Physicochemical Properties of Membranes are Related to Flavor Production during Sake Brewing in the Yeast Saccharomyces cerevisiae. MEMBRANES 2020; 10:membranes10120440. [PMID: 33352892 PMCID: PMC7766171 DOI: 10.3390/membranes10120440] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Revised: 12/15/2020] [Accepted: 12/16/2020] [Indexed: 12/17/2022]
Abstract
Ethyl caproate (EC) and isoamyl acetate (IA) are key flavor components of sake. Recently, attempts have been made to increase the content of good flavor components, such as EC and IA, in sake brewing. However, the functions of EC and IA in yeast cells remain poorly understood. Therefore, we investigated the effects of EC and IA using cell-sized lipid vesicles. We also investigated lipid vesicles containing EC and/or caproic acid (CA) as well as IA and/or isoamyl alcohol (IAA). CA and IAA are precursors of EC and IA, respectively, and are important flavors in sake brewing. The size of a vesicle is influenced by flavor compounds and their precursors in a concentration-dependent manner. We aimed to establish the conditions in which the vesicles contained more flavors simultaneously and with different ratios. Interestingly, vesicles were largest in a mixture of 50% of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) with 25% EC and 25% CA or a mixture of 50% DOPC with 25% IA and 25% IAA. The impact of flavor additives on membrane fluidity was also studied using Laurdan generalized polarization. During the production process, flavors may regulate the fluidity of lipid membranes.

Sharma N, Baek K, Phan HTT, Shimokawa N, Takagi M. Glycosyl chains and 25-hydroxycholesterol contribute to the intracellular transport of amyloid beta (Aβ-42) in Jurkat T cells. FEBS Open Bio 2017; 7:865-876.

Abstract
Amyloid beta (Aβ) is a peptide responsible for the development of Alzheimer's disease (AD). Misfolding and accumulation of endogenous Aβ can lead to neural cell apoptosis through endoplasmic reticulum (ER) stress. Added exogenous Aβ can also result in ER stress, leading to neurotoxicity and apoptosis, which is identical to that caused by the endogenous peptide. We have speculated that the endocytic transport of Aβ causes ER stress and have previously shown that the oxysterol, in particular, 7-ketocholesterol (7-keto) induces more surface interaction between Aβ-42 and Jurkat cells than cholesterol. However, the interaction was not enough to induce intracellular transfer of the peptide. In this study, we investigated the effect of another oxysterol, 25-hydroxycholesterol (25-OH) on the membrane raft-dependent transport of Aβ-42 in Jurkat cells. Interestingly, intracellular transfer of Aβ-42 was observed in the presence of 25-OH only after the inclusion of cholera toxin B subunit (CT-B), a marker used to detect the raft domain. We speculated that 25-OH can induce intracellular movement of Aβ peptides. Furthermore, CT-B together with GM1 provided negative curvature, which resulted in the intracellular transport of Aβ-42. Notably, we used a protofibrillar species of Aβ-42 in this study. We have shown that the transport was microtubule-dependent since it could not be observed in depolymerized microtubules. These results demonstrate that oxysterols and glycosyl chains are important factors affecting intracellular transport. These compounds are also associated with aging and advanced glycation are risk factors for AD. Thus, this study should further understanding of the pathology of AD.
