Inulin alleviates HFD-induced NAFLD by hepatic macrophage polarization and lipid metabolism via gut-liver axis

引用

Food Science and Human Wellness 2024年

作者： Wei Song Jinhong Hu Lina Zhu Bing Chen Lingling Li Xiaole Cui Ting Zhang Yaxing Miao Kaixin Su Changchun Liu Yane Luo Tianli Yue College of Food Science and Technology， laboratory of nutritional and Healthy Food-Individuation Manufacturing Engineering， research Center of Food Safety Risk Assessment and Control， Northwest University

Long-term intake of high-fat diet (HFD) leads to systemic hypo-inflammation， which is involved in the pathogenesis of many liver diseases. The aim of this study was to evaluate the interventional effect of inulin addition on HFD-induced non-alcoholic fatty liver disease (NAFLD). Here， we assessed liver inflammation and lipid metabolism by ELISA kits and real-time quantitative polymerase chain reaction (qPCR)， and explored its relationship with intestinal flora and metabolites by 16S rDNA gene sequencing and untargeted metabolomics. In addition， we determined the effect of the inositol-requiring enzyme-1α (IRE1α-XBP1) pathway on liver macrophage polarization by flow cytometry. In conclusion， our study has demonstrated that inulin ameliorates high levels of bile acids and colonic immune disorders induced by HFD， and improves hepatic macrophage polarization and hepatic lipid metabolism via the intestine-hepatic axis， thus providing a mechanistic basis for therapeutic approaches to modulate bile acids to improve colonic inflammation and nonalcoholic fatty liver disease.

Identification of porcine fast/slow myogenic exosomes and their regulatory effects on lipid accumulation in intramuscular adipocytes

Background Pork quality is affected by the type of muscle fibers, which is closely related to meat color, tenderness and juiciness. Exosomes are tiny vesicles with a diameter of approximately 30–150 nm that are secreted by cells and taken up by recipient cells to mediate communication. Exosome-mediated muscle-fat tissue crosstalk is a newly discovered mechanism that may have an important effect on intramuscular fat deposition and with that on meat quality. Various of adipose tissue-derived exosomes have been discovered and identified, but the identification and function of muscle exosomes, especially porcine fast/slow myotube exosomes, remain unclear. Here, we first isolated and identified exosomes secreted from porcine extensor digitorum longus(EDL) and soleus(SOL), which represent fast and slow muscle, respectively, and further explored their effects on lipid accumulation in longissimus dorsi *** Porcine SOL-derived exosomes(SOL-EXO) and EDL-derived exosomes(EDL-EXO) were first identified and their average particle sizes were approximately 84 nm with double-membrane disc-shapes as observed via transmission electron microscopy and scanning electron microscopy. Moreover, the intramuscular fat content of the SOL was greater than that of the EDL at 180 days of age, because SOL intramuscular adipocytes had a stronger lipid-accumulating capacity than those of the EDL. Raman spectral analysis revealed that SOL-EXO protein content was much greater than that of EDL-EXO. Proteomic sequencing identified 72 proteins that were significantly differentially expressed between SOL-EXO and EDL-EXO, 31 of which were downregulated and 41 of which were upregulated in *** Our findings suggest that muscle-fat tissue interactions occur partly via SOL-EXO promoting adipogenic activity of intramuscular adipocytes.

Role of microbiota-gut-brain axis in neurodegenerative diseases and the potential of microbiome-targeted d ietary strategies: A review of current evidence and future perspective

Neurodegenerative diseases (NDs)， mainly including Alzheimer’s disease， Parkinson’s disease， and Multiple sclerosis， represent a major public health challenge with the steady increase of aging population worldwide. Emerging evidence has revealed the key role of the microbiota-gut-brain axis in the pathogenesis of NDs. Diet is one of the most important environmental factors shaping the structure and function of gut microbiota. Manipulating the gut microbiota through specific diet patterns may represent a promising approach for NDs prevention. In this review， we highlight gut microbiota variations in NDs， outline several crucial signaling pathways of the gut-brain communication， and discuss the interplay of nutrients-microbes and biological effect of diet-derived microbial metabolites on neural physiology. In particular， we summarized the current knowledge about the application of dietary patterns in NDs to prevent disease progression via the modulation of the gut microbiota. Our study provides novel insights on the diet-microbiota-gut-brain axis in neurodegenerative disorders and highlights the potential of developing microbiome-targeted personalized dietary intervention for NDs management.

Insects show highly complicated adaptive and sophisticated behaviors, includ-ing spatial orientation skills, learning ability, and social interaction. These behaviors arecontrolled by the insect brain, the central part of the nervous system. The tiny insect brainconsists of millions of highly differentiated and interconnected cells forming a complexnetwork. Decades of research has gone into an understanding of which parts of the insectbrain possess particular behaviors, but exactly how they modulate these functional conse-quences needs to be clarified. Detailed description of the brain and behavior is required todecipher the complexity of cell types, as well as their connectivity and function. Single-cell RNA-sequencing (scRNA-seq) has emerged recently as a breakthrough technologyto understand the transcriptome at cellular resolution. With scRNA-seq, it is possible touncover the cellular heterogeneity of brain cells and elucidate their specific functions andstate. In this review, we first review the basic structure of insect brains and the links toinsect behaviors mainly focusing on learning and memory. Then the scRNA applicationson insect brains are introduced by representative studies. Single-cell RNA-seq has allowedresearchers to classify cell subpopulations within different insect brain regions, pinpointsingle-cell developmental trajectories, and identify gene regulatory networks. These devel-opments empower the advances in neuroscience and shed light on the intricate problemsin understanding insect brain functions and behaviors.
