The gut microbiota is now considered as one of the key elements contributing to regulation host health. Virtually all our body sites are colonised by microbes suggesting different types crosstalk with organs. Because development molecular tools and techniques (ie, metagenomic, metabolomic, lipidomic, metatranscriptomic), complex interactions occurring between microorganisms progressively being deciphered. Nowadays, deviations linked many diseases including obesity, type 2 diabetes, hepatic steatosis, intestinal bowel (IBDs) several cancer. Thus, that various pathways involved in immunity, energy, lipid glucose metabolism affected. In this review, specific attention given provide a critical evaluation current understanding field. Numerous mechanisms explaining how bacteria might be causally protection or onset discussed. We examine well-established metabolites short-chain fatty acids, bile trimethylamine N-oxide) extend more recently identified actors endocannabinoids, bioactive lipids, phenolic-derived compounds, advanced glycation end products enterosynes) their receptors such peroxisome proliferator-activated receptor alpha (PPARα) gamma (PPARγ), aryl hydrocarbon (AhR), G protein-coupled GPR41, GPR43, GPR119, Takeda 5).

Gut-liver-brain axis is a three-way highway of information interaction system among the gastrointestinal tract, liver, and nervous systems. In past few decades, breakthrough progress has been made in gut liver brain axis, mainly through understanding its formation mechanism increasing treatment strategies. this review, we discuss various complex networks including barrier permeability, hormones, microbial metabolites, vagus nerve, neurotransmitters, immunity, toxic β-amyloid (Aβ) metabolism, epigenetic regulation gut-liver-brain axis. Some therapies containing antibiotics, probiotics, prebiotics, synbiotics, fecal microbiota transplantation (FMT), polyphenols, low FODMAP diet nanotechnology application regulate Besides, some special treatments targeting gut-liver include farnesoid X receptor (FXR) agonists, takeda G protein-coupled 5 (TGR5) glucagon-like peptide-1 (GLP-1) antagonists fibroblast growth factor 19 (FGF19) analogs. Targeting gut-brain embraces cognitive behavioral therapy (CBT), antidepressants tryptophan metabolism-related therapies. liver-brain contains Aβ future, better interactions will promote development novel preventative strategies discovery precise therapeutic targets multiple diseases.

Dietary proteins derived from animal sources, although containing well-balanced profiles of essential amino acids, have considerable environmental and adverse health effects associated with the intake some protein-based products. Consuming foods based on carries a higher risk developing non-communicable diseases such as cancer, heart disease, non-alcoholic fatty liver disease (NAFLD), inflammatory bowel (IBD). Moreover, dietary protein consumption is increasing due to population growth, posing supply challenge. There is, therefore, growing interest in discovering novel alternative sources. In this context, microalgae been recognized strategic crops that can provide sustainable source protein. Compared conventional high-protein crops, using microalgal biomass for production presents several advantages food feed terms productivity, sustainability, nutritional value. positively impact environment by not exploiting land or causing water pollution. Many studies revealed potential an added value positive human their anti-inflammatory, antioxidant, anti-cancer properties.

The rising prevalence of liver diseases related to obesity and excessive use alcohol is fuelling an increasing demand for accurate biomarkers aimed at community screening, diagnosis steatohepatitis significant fibrosis, monitoring, prognostication prediction treatment efficacy. Breakthroughs in omics methodologies the power bioinformatics have created excellent opportunity apply technological advances clinical needs, instance development precision personalised medicine. Via technologies, biological processes from genes circulating protein, as well microbiome - including bacteria, viruses fungi, can be investigated on axis. However, there are important barriers omics-based biomarker discovery validation, semi-quantitative measurements untargeted platforms, which may exhibit high analytical, inter- intra-individual variance. Standardising methods need validate them across diverse populations presents a challenge, partly due disease complexity dynamic nature expression different stages. Lack validity causes lost opportunities when studies fail provide knowledge needed regulatory approvals, all contributes delayed translation these discoveries into practice. While no matured implementation, extent data generated has enabled hypothesis-free plethora candidate that warrant further validation.

Abstract Alcohol use disorder is a major cause of morbidity, which requires newer treatment approaches. We previously showed in randomized clinical trial that alcohol craving and consumption reduces after fecal transplantation. Here, to determine if this could be transmitted through microbial transfer, germ-free male C57BL/6 mice received stool or sterile supernatants collected from the participants pre-/post-fecal transplant. found colonized with post-fecal transplant but not reduced ethanol acceptance, intake preference versus pre-fecal mice. Microbial taxa were higher humans also associated lower murine preference. A majority differentially expressed genes (immune response, inflammation, oxidative stress epithelial cell proliferation) occurred intestine rather than liver prefrontal cortex. These findings suggest potential for therapeutically targeting gut microbiota microbial-intestinal interface alter gut-liver-brain axis reduce humans.
