The outermost epidermal layer of the skin, the stratum corneum, is not simply a barrier that safeguards skin integrity from external insults and invaders, it is also a delicately integrated interface composed of firm, essentially dead corneocytes and a distinctive lipid matrix. Together, the stratum corneum lipid matrix and sebum lipids derived from sebaceous glands give rise to a remarkably complex but quite unique blend of skin surface lipids that demonstrates tremendous heterogeneity and provides the skin with its indispensable protective coating. The stratum corneum lipid matrix is composed primarily of three major lipid classes: ceramides, non-esterified fatty acids and cholesterol, whereas sebum is a waxy mixture predominantly composed of acylglycerols, wax esters, non-esterified fatty acids, squalene, cholesterol and cholesterol esters. The balance of these skin surface lipids in terms of their relative abundance, composition, molecular organisation and dynamics, and their intricate interactions play a crucial role in the maintenance of healthy skin. For that reason, even minuscule alterations in skin surface lipid properties or overall lipid profile have been implicated in the aetiology of many common skin diseases including atopic dermatitis, psoriasis, xerosis, ichthyosis and acne. Novel lipid-based interventions aimed at correcting the skin surface lipid abnormalities have the potential to repair skin barrier integrity and the symptoms associated with such skin diseases, even though the exact mechanisms of lipid restoration remain elusive.

皮肤最外层的表皮层,即角质层,不仅仅是保护皮肤完整性免受外部损伤和入侵者侵害的屏障,它还是一个由坚硬的、基本上已经死亡的角质细胞和独特的脂质基质组成的精细集成界面。角质层脂质基质和来自皮脂腺的皮脂脂质共同形成了一种非常复杂但非常独特的皮肤表面脂质混合物,表现出巨大的异质性,并为皮肤提供了不可或缺的保护涂层。角质层脂质基质主要由三类主要脂质组成:神经酰胺、非酯化脂肪酸和胆固醇,而皮脂是一种蜡状混合物,主要由酰基甘油、蜡酯、非酯化的脂肪酸、角鲨烯、胆固醇和胆固醇酯组成。这些皮肤表面脂质在相对丰度、组成、分子组织和动力学方面的平衡,以及它们复杂的相互作用,在维持健康皮肤方面发挥着至关重要的作用。因此,皮肤表面脂质特性或整体脂质特征的微小变化也与许多常见皮肤病的病因有关,包括特应性皮炎、银屑病、干燥症、鱼鳞病和痤疮。旨在纠正皮肤表面脂质异常的新型脂质干预措施有可能修复皮肤屏障完整性和与此类皮肤疾病相关的症状,尽管脂质恢复的确切机制尚不清楚。

The prevalence of Alzheimer's disease (AD) continues to rise due to the increasing aging population. Among the various genetic factors associated with AD, apolipoprotein E (ApoE), a lipid transporter, stands out as the primary genetic risk factor. Specifically, individuals carrying the ApoE4 allele exhibit a significantly higher risk. However, emerging research indicates that dietary factors play a prominent role in modifying the risk of AD. Docosahexaenoic acid (DHA), a prominent ω-3 fatty acid, has garnered considerable attention for its potential to ameliorate cognitive function. The intricate interplay between DHA and the ApoE genotype within the brain, which may influence DHA's utilization and functionality, warrants further investigation. This review meticulously examines experimental and clinical studies exploring the effects of DHA on cognitive decline. Special emphasis is placed on elucidating the role of ApoE gene polymorphism and the underlying mechanisms are discussed. These studies suggest that early DHA supplementation may confer benefits to cognitively normal older adults carrying the ApoE4 gene. However, once AD develops, ApoE4 non-carriers may experience greater benefits compared to ApoE4 carriers, although the overall effectiveness of DHA supplementation at this stage is limited. Potential mechanisms underlying these differential effects may include accelerated DHA catabolism in ApoE4 carriers, impaired transport across the blood-brain barrier (BBB), and compromised lipidation and circulatory function in ApoE4 carriers. Thus, the supplementation of DHA may represent a potential intervention strategy aimed at compensating for these deficiencies in ApoE4 carriers prior to the onset of AD.

由于人口老龄化的加剧,阿尔茨海默病(AD)的患病率持续上升。在与AD相关的各种遗传因素中,载脂蛋白E(ApoE)是一种脂质转运蛋白,是主要的遗传风险因素。具体而言,携带ApoE4等位基因的个体表现出明显更高的风险。然而,新的研究表明,饮食因素在改变AD风险方面发挥着重要作用。二十二碳六烯酸(DHA)是一种重要的ω-3脂肪酸,因其改善认知功能的潜力而备受关注。大脑中DHA和ApoE基因型之间错综复杂的相互作用可能影响DHA的利用和功能,值得进一步研究。这篇综述仔细研究了探索DHA对认知能力下降影响的实验和临床研究。特别强调阐明ApoE基因多态性的作用,并讨论了潜在的潜在机制。这些研究表明,早期补充DHA可能对携带ApoE4基因的认知正常的老年人有益。然而,一旦AD发生,与ApoE4携带者相比,ApoE4非携带者可能会获得更大的益处,尽管在这一阶段补充DHA的总体有效性有限。这些差异效应的潜在机制可能包括ApoE4载体中DHA分解代谢加速、血脑屏障(BBB)转运受损,以及ApoE4携带者的脂质化和循环功能受损。因此,补充DHA可能是一种潜在的干预策略,旨在弥补AD发病前ApoE4携带者的这些缺陷。

Conjugated linoleic acid (CLA) is a functional food ingredient with prebiotic properties that provides health benefits for various human pathologies and disorders. However, limited natural CLA sources in animals and plants have led microorganisms like Lactobacillus and Bifidobacterium to emerge as new CLA sources. Microbial conversion of linoleic acid to CLA is mediated by linoleic acid isomerase and multicomponent enzymatic systems, with CLA production efficiency dependent on microbial species and strains. Additionally, complex factors like LA concentration, growth status, culture substrates, precursor type, prebiotic additives, and co-cultured microbe identity strongly influence CLA production and isomer composition. This review summarizes advances in the past decade regarding microbial CLA production, including bacteria and fungi. We highlight CLA production and potential regulatory mechanisms and discuss using microorganisms to enhance CLA content and nutritional value of fermented products. We also identify primary microbial CLA production bottlenecks and provide strategies to address these challenges and enhance production through functional gene and enzyme mining and downstream processing. This review aims to provide a reference for microbial CLA production and broaden the understanding of the potential probiotic role of microbial CLA producers.

共轭亚油酸(CLA)是一种具有益生元特性的功能性食品成分,可为各种人类疾病和病症提供健康益处。然而,动物和植物中有限的天然CLA来源导致乳酸杆菌和双歧杆菌等微生物成为新的CLA来源。微生物将亚油酸转化为CLA是由亚油酸异构酶和多组分酶系统介导的,CLA的生产效率取决于微生物种类和菌株。此外,LA浓度、生长状态、培养基质、前体类型、益生元添加剂和共培养微生物特性等复杂因素强烈影响CLA的产生和异构体组成。本文综述了近十年来微生物CLA生产的进展,包括细菌和真菌。我们强调了CLA的产生和潜在的调节机制,并讨论了利用微生物提高发酵产品的CLA含量和营养价值。我们还确定了主要的微生物CLA生产瓶颈,并提供了应对这些挑战的策略,并通过功能基因和酶挖掘以及下游加工来提高生产。这篇综述旨在为微生物CLA生产提供参考,并拓宽对微生物CLA生产者潜在益生菌作用的理解。

Recently, omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) have gained substantial interest due to their specific structure and biological functions. Humans cannot naturally produce these fatty acids (FAs), making it crucial to obtain them from our diet. This comprehensive review details n-3 LC-PUFAs and their role in promoting and maintaining optimal health. The article thoroughly analyses several sources of n-3 LC-PUFAs and their respective bioavailability, covering marine, microbial and plant-based sources. Furthermore, we provide an in-depth analysis of the biological impacts of n-3 LC-PUFAs on health conditions, with particular emphasis on cardiovascular disease (CVD), gastrointestinal (GI) cancer, diabetes, depression, arthritis, and cognition. In addition, we highlight the significance of fortification and supplementation of n-3 LC-PUFAs in both functional foods and dietary supplements. Additionally, we conducted a detailed analysis of the several kinds of n-3 LC-PUFAs supplements currently available in the market, including an assessment of their recommended intake, safety, and effectiveness. The dietary guidelines associated with n-3 LC-PUFAs are also highlighted, focusing on the significance of maintaining a well-balanced intake of n-3 PUFAs to enhance health benefits. Lastly, we highlight future directions for further research in this area and their potential implications for public health.

近年来,ω-3长链多不饱和脂肪酸(n-3LC-PUFA)由于其特殊的结构和生物功能而引起了人们的极大兴趣。人类无法自然产生这些脂肪酸,因此从我们的饮食中获取这些脂肪酸至关重要。这篇综合综述详细介绍了n-3 LC PUFA及其在促进和保持最佳健康方面的作用。本文全面分析了n-3LC-PUFA的几种来源及其各自的生物利用度,包括海洋、微生物和植物来源。此外,我们对n-3 LC-PUFA对健康状况的生物学影响进行了深入分析,特别强调心血管疾病(CVD)、胃肠道(GI)癌症、糖尿病、抑郁症、关节炎和认知。此外,我们强调了在功能性食品和膳食补充剂中强化和补充n-3LC-PUFA的重要性。此外,我们对目前市场上可用的几种n-3LC-PUFA补充剂进行了详细分析,包括对其推荐摄入量、安全性和有效性的评估。还强调了与n-3 LC PUFA相关的饮食指南,重点是保持n-3 PUFA的均衡摄入对提高健康益处的重要性。最后,我们强调了该领域未来进一步研究的方向及其对公共卫生的潜在影响。

MDD (major depressive disorder) is a highly prevalent mental disorder with a complex etiology involving behavioral and neurochemical factors as well as environmental stress. The interindividual variability in response to stress stimuli may be explained by processes such as long-term potentiation (LTP) and long-term depression (LTD). LTP can be described as the strengthening of synaptic transmission, which translates into more efficient cognitive performance and is regulated by brain-derived neurotrophic factor (BDNF), a protein responsible for promoting neural growth. It is found in high concentrations in the hippocampus, a part of the limbic system which is far less active in people with MDD. Omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) not only contribute to structural and antioxidative functions but are essential for the maintenance of LTP and stable BDNF levels. This review explores the mechanisms and potential roles of omega-3 fatty acids in the prevention of MDD.

MDD(重性抑郁障碍)是一种高度流行的精神障碍,其病因复杂,涉及行为和神经化学因素以及环境压力。个体对压力刺激反应的变异性可以用长时程增强(LTP)和长期抑郁(LTD)等过程来解释。LTP可以被描述为突触传递的增强,这转化为更有效的认知表现,并受到脑源性神经营养因子(BDNF)的调节,BDNF是一种负责促进神经生长的蛋白质。它在海马体中高浓度存在,海马体是MDD患者的边缘系统的一部分,其活性要低得多。ω-3脂肪酸,如二十碳五烯酸(EPA)和二十二碳六烯酸(DHA),不仅有助于结构和抗氧化功能,而且对维持LTP和稳定的BDNF水平至关重要。这篇综述探讨了ω-3脂肪酸在预防MDD中的机制和潜在作用。

The barrier function of the skin is primarily located in the stratum corneum (SC), the outermost layer of the skin. The SC is composed of dead cells with highly organized lipid lamellae in the intercellular space. As the lipid matrix forms the only continuous pathway, the lipids play an important role in the permeation of compounds through the SC. The main lipid classes are ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs). Analysis of the SC lipid matrix is of crucial importance in understanding the skin barrier function, not only in healthy skin, but also in inflammatory skin diseases with an impaired skin barrier. In this review we provide i) a historical overview of the steps undertaken to obtain information on the lipid composition and organization in SC of healthy skin and inflammatory skin diseases, ii) information on the role CERs, CHOL and FFAs play in the lipid phase behavior of very complex lipid model systems and how this knowledge can be used to understand the deviation in lipid phase behavior in inflammatory skin diseases, iii) knowledge on the role of both, CER subclasses and chain length distribution, on lipid organization and lipid membrane permeability in complex and simple model systems with synthetic CERs, CHOL and FFAs, iv) similarity in lipid phase behavior in SC of different species and complex model systems, and vi) future directions in modulating lipid composition that is expected to improve the skin barrier in inflammatory skin diseases.

皮肤的屏障功能主要位于角质层(SC),即皮肤的最外层。SC由死细胞组成,细胞间隙中有高度组织化的脂质片层。由于脂质基质形成了唯一的连续途径,脂质在化合物通过SC的渗透中发挥着重要作用。主要的脂质类别是神经酰胺(CERs)、胆固醇(CHOL)和游离脂肪酸(FFAs)。SC脂质基质的分析对于理解皮肤屏障功能至关重要,不仅在健康皮肤中,而且在皮肤屏障受损的炎症性皮肤病中也是如此。在这篇综述中,我们提供了i)为获得健康皮肤和炎症性皮肤病SC中脂质组成和组织的信息而采取的步骤的历史概述,ii)关于CER的作用的信息,CHOL和FFA在非常复杂的脂质模型系统的脂质相行为中发挥作用,以及如何使用这些知识来理解炎症性皮肤病中脂质相行为的偏差,iii)关于两者的作用、CER亚类和链长分布、关于具有合成CER的复杂和简单模型系统中的脂质组织和脂质膜渗透性的知识,CHOL和FFAs,iv)不同物种和复杂模型系统的SC中脂相行为的相似性,以及vi)调节脂质组成的未来方向,有望改善炎症性皮肤病中的皮肤屏障。

The unique biophysical and biochemical properties of lipids render them crucial in most models of the origin of life (OoL). Many studies have attempted to delineate the prebiotic pathways by which lipids were formed, how micelles and vesicles were generated, and how these micelles and vesicles became selectively permeable towards the chemical precursors required to initiate and support biochemistry and inheritance. Our analysis of a number of such studies highlights the extremely narrow and limited range of conditions by which an experiment is considered to have successfully modeled a role for lipids in an OoL experiment. This is in line with a recent proposal that bias is introduced into OoL studies by the extent and the kind of human intervention. It is self-evident that OoL studies can only be performed by human intervention, and we now discuss the possibility that some assumptions and simplifications inherent in such experimental approaches do not permit determination of mechanistic insight into the roles of lipids in the OoL. With these limitations in mind, we suggest that more nuanced experimental approaches than those currently pursued may be required to elucidate the generation and function of lipids, micelles and vesicles in the OoL.

脂质独特的生物物理和生化特性使它们在大多数生命起源模型中至关重要。许多研究试图描述脂质形成的益生元途径,胶束和囊泡是如何产生的,以及这些胶束和囊泡是如何选择性地渗透到启动和支持生物化学和遗传所需的化学前体的。我们对许多这类研究的分析强调,一个实验被认为成功地模拟了脂质在OoL实验中的作用,其条件范围极其狭窄和有限。这与最近的一项建议一致,即人为干预的程度和种类会将偏见引入OoL研究。不言而喻,OoL研究只能通过人为干预来进行,我们现在讨论这种实验方法中固有的一些假设和简化的可能性,这些假设和简化不允许确定脂质在OoL中的作用的机制洞察力。考虑到这些局限性,我们建议可能需要比目前所追求的更细致的实验方法来阐明油脂、胶束和囊泡的产生和功能。

Sphingolipids are essential components of all eukaryotic membranes. The bioactive sphingolipid molecule, Sphingosine 1-Phosphate (S1P), regulates various important biological functions. This review aims to provide a comprehensive overview of the role of S1P signaling pathway in various immune cell functions under different pathophysiological conditions including bacterial and viral infections, autoimmune disorders, inflammation, and cancer. We covered the aspects of S1P pathways in NOD/TLR pathways, bacterial and viral infections, autoimmune disorders, and tumor immunology. This implies that targeting S1P signaling can be used as a strategy to block these pathologies. Our current understanding of targeting various components of S1P signaling for therapeutic purposes and the present status of S1P pathway inhibitors or modulators in disease conditions where the host immune system plays a pivotal role is the primary focus of this review.

鞘脂是所有真核生物膜的基本成分。生物活性鞘脂分子sphingosin 1-Phosphate (S1P)调节多种重要的生物功能。本文旨在全面综述S1P信号通路在不同病理生理条件下(包括细菌和病毒感染、自身免疫性疾病、炎症和癌症)在各种免疫细胞功能中的作用。我们涵盖了NOD/TLR通路中S1P通路、细菌和病毒感染、自身免疫性疾病和肿瘤免疫学的各个方面。这意味着靶向S1P信号可以作为阻断这些病理的策略。我们目前对靶向S1P信号的各种成分用于治疗目的的理解,以及在宿主免疫系统起关键作用的疾病条件下S1P通路抑制剂或调节剂的现状是本综述的主要重点。

Macrophages are essential innate immune cells and form our first line of immune defense. Also known as professional phagocytes, macrophages interact and take up various particles, including lipids. Defective lipid handling can drive excessive lipid accumulation leading to foam cell formation, a key feature of various cardiometabolic conditions such as atherosclerosis, non-alcoholic fatty liver disease, and obesity. At the same time, intracellular lipid storage and foam cell formation can also be viewed as a protective and anti-lipotoxic mechanism against a lipid-rich environment and associated elevated lipid uptake. Traditionally, foam cell formation has primarily been linked to cholesterol uptake via native and modified low-density lipoproteins. However, other lipids, including non-esterified fatty acids and triacylglycerol (TAG)-rich lipoproteins (very low-density lipoproteins and chylomicrons), can also interact with macrophages. Recent studies have identified multiple pathways mediating TAG uptake and processing by macrophages, including endocytosis and receptor/transporter-mediated internalization and transport. This review will present the current knowledge of how macrophages take up different lipids and lipoprotein particles and address how TAG-rich lipoproteins are processed intracellularly. Understanding how macrophages take up and process different lipid species such as TAG is necessary to design future therapeutic interventions to correct excessive lipid accumulation and associated co-morbidities.

巨噬细胞是必不可少的先天免疫细胞,构成我们的第一道免疫防线。巨噬细胞也被称为专业吞噬细胞,它们相互作用并吸收各种颗粒,包括脂质。脂质处理缺陷会导致脂质过度积累,导致泡沫细胞形成,这是动脉粥样硬化、非酒精性脂肪肝和肥胖等各种心脏代谢疾病的关键特征。同时,细胞内脂质储存和泡沫细胞的形成也可以被视为对富含脂质的环境和相关的脂质摄取升高的保护性和抗脂毒性机制。传统上,泡沫细胞的形成主要与通过天然和修饰的低密度脂蛋白摄取胆固醇有关。然而,其他脂质,包括非酯化脂肪酸和富含三酰甘油(TAG)的脂蛋白(非常低密度的脂蛋白和乳糜微粒),也可以与巨噬细胞相互作用。最近的研究已经确定了介导巨噬细胞摄取和处理TAG的多种途径,包括内吞作用和受体/转运蛋白介导的内化和转运。这篇综述将介绍巨噬细胞如何吸收不同的脂质和脂蛋白颗粒的最新知识,并阐述富含TAG的脂蛋白是如何在细胞内处理的。了解巨噬细胞如何吸收和处理不同的脂质物质,如TAG,对于设计未来的治疗干预措施以纠正过度的脂质积聚和相关的并发症是必要的。

FADS2 function at the major cancer hotspot 11q13 locus alters fatty acid metabolism in cancer FADS2在主要癌症热点11q13位点的功能改变了癌症中的脂肪酸代谢

Dysregulation of fatty acid metabolism and de novo lipogenesis is a key driver of several cancer types through highly unsaturated fatty acid (HUFA) signaling precursors such as arachidonic acid. The human chromosome 11q13 locus has long been established as the most frequently amplified in a variety of human cancers. The fatty acid desaturase genes (FADS1, FADS2 and FADS3) responsible for HUFA biosynthesis localize to the 11q12-13.1 region. FADS2 activity is promiscuous, catalyzing biosynthesis of several unsaturated fatty acids by Δ6, Δ8, and Δ4 desaturation. Our main aim here is to review known and putative consequences of FADS2 dysregulation due to effects on the 11q13 locus potentially driving various cancer types. FADS2 silencing causes synthesis of sciadonic acid (5Z,11Z,14Z-20:3) in MCF7 cells and breast cancer in vivo. 5Z,11Z,14Z-20:3 is structurally identical to arachidonic acid (5Z,8Z,11Z,14Z–20:4) except it lacks the internal Δ8 double bond required for prostaglandin and leukotriene synthesis, among other eicosanoids. Palmitic acid has substrate specificity for both SCD and FADS2. Melanoma, prostate, liver and lung cancer cells insensitive to SCD inhibition show increased FADS2 activity and sapienic acid biosynthesis. Elevated serum mead acid levels found in hepatocellular carcinoma patients suggest an unsatisfied demand for arachidonic acid. FADS2 circular RNAs are at high levels in colorectal and lung cancer tissues. FADS2 circular RNAs are associated with shorter overall survival in colorectal cancer patients. The evidence thusfar supports an effort for future research on the role of FADS2 as a tumor suppressor in a range of neoplastic disorders.

通过高不饱和脂肪酸(HUFA)信号前体如花生四烯酸,脂肪酸代谢和新生脂肪生成的失调是几种癌症类型的关键驱动因素。人类染色体11q13位点长期以来一直被确定为各种人类癌症中最常扩增的位点。负责HUFA生物合成的脂肪酸去饱和酶基因(FADS1、FADS2和FADS3)定位于11q12-13.1区域。FADS2活性是混杂的,通过Δ6, Δ8和Δ4去饱和催化几种不饱和脂肪酸的生物合成。我们在这里的主要目的是回顾已知的和假定的FADS2失调的后果,这是由于对11q13位点的影响可能导致各种癌症类型。FADS2沉默导致MCF7细胞和乳腺癌体内合成坐骨酸(5Z,11Z,14Z-20:3)。5Z,11Z,14Z-20:3在结构上与花生四烯酸(5Z,8Z,11Z, 14Z-20:4)相同,只是缺乏合成前列腺素和白三烯所需的内部Δ8双键。棕榈酸对SCD和FADS2都具有底物特异性。对SCD抑制不敏感的黑色素瘤、前列腺癌、肝癌和肺癌细胞显示FADS2活性和皂苷酸生物合成增加。肝细胞癌患者血清蜂蜜酸水平升高提示对花生四烯酸的需求未得到满足。FADS2环状rna在结直肠癌和肺癌组织中处于高水平。FADS2环状rna与结直肠癌患者较短的总生存期相关。到目前为止,这些证据支持了FADS2作为肿瘤抑制因子在一系列肿瘤疾病中的作用的未来研究。
