Short-chain fatty acids-producing probiotics: A novel source of psychobiotics

Butyrate, Gut Dysbiosis, Gut-Brain axis, Metabolites, Mitochondria, Probiotics, Prebiotics and Symbiotics, Short Chain Fatty Acids /

Psychobiotics—live microorganisms with potential mental health benefits, which can modulate the microbiota-gut-brain-axis via immune, humoral, neural, and metabolic pathways—are emerging as novel therapeutic options for the effective treatment of psychiatric disorders Recently, microbiome studies have identified numerous putative psychobiotic strains, of which short-chain fatty acids (SCFAs) producing bacteria have attracted special attention from neurobiologists. Recent […]

Exploration of Host Health Benefits by a Defined Consortium of Butyrate-Producing Human Gut Bacteria In Gnotobiotic Mouse Model

Butyrate, Gut Dysbiosis, Gut Microbiota, Gut Permeability / Leaky Gut, Metabolites, Mitochondria, Short Chain Fatty Acids /

Aberrant gut microbiota composition is found to be associated with several human diseases such as inflammatory bowel diseases (IBD). Reduction in butyrate producing bacteria is one of the characteristic features of such dysbiotic bacterial community in the gut. Modulation of gut microbiota to bring the dysbiotic state back to normal healthy state is a promising

Investigating Causal Relations Between Circulating Metabolites and Alzheimer’s Diseases: a Mendelian Randomization Study

Metabolites /

Our findings provided robust evidence supporting causal effects of circulating glycoprotein acetyls, ApoB, LDL cholesterol, and serum total cholesterol on higher risk of AD, whereas glutamine showed the protective effect. Further research is required to decipher the biological pathways underpinning associations. CLICK TO REVIEW

Gut Microbial Metabolites in Parkinson’s Disease: Implications of Mitochondrial Dysfunction in the Pathogenesis and Treatment

Gut Dysbiosis, Gut Microbiota, Metabolites, Mitochondria /

The search for therapeutic targets for Parkinson’s disease (PD) is hindered by the incomplete understanding of the pathophysiology of the disease. Mitochondrial dysfunction is an area with high potential. The neurobiological signaling connections between the gut microbiome and the central nervous system are incompletely understood. Multiple lines of evidence suggest that the gut microbiota participates

Internal connections between dietary intake and gut microbiota homeostasis in disease progression of ulcerative colitis

Butyrate, Gut Dysbiosis, Gut Microbiota, Gut Permeability / Leaky Gut, Metabolites, Pre-PD /

These findings suggest that varieties in dietary patterns result in the production of diverse microbial fermentation metabolites, which contribute to gut microbiome homeostasis through multiple manipulations including immune modulation, inflammation restriction as well as epithelial barrier maintenance, thus finally determine the fate of UC progression and give implications for functional food development for prevention and

Previous studies have reported that gut microbiota, permeability, short-chain fatty acids (SCFAs), and inflammation are altered in Parkinson’s disease (PD), but how these factors are linked and how they contribute to disease processes and symptoms remains uncertain. This study sought to compare and identify associations among these factors in PD patients and controls to elucidate

Meta-analysis of the Parkinson’s disease gut microbiome suggests alterations linked to intestinal inflammation

Biomarkers, Butyrate, Gut Dysbiosis, Gut Permeability / Leaky Gut, Metabolites, Pre-PD, Short Chain Fatty Acids /

We found significant alterations in the PD-associated microbiome, which are robust to study-specific technical heterogeneities, although differences in microbiome structure between PD and controls are small. Enrichment of the genera Lactobacillus, Akkermansia, and Bifidobacterium and depletion of bacteria belonging to the Lachnospiraceae family and the Faecalibacterium genus, both important short-chain fatty acids producers, emerged as

The Role of Gut Bacterial Metabolites in Brain Development, Aging and Disease

Biomarkers, Butyrate, Gut Microbiota, Gut-Brain axis, Metabolites, Short Chain Fatty Acids /

We found significantly altered SCFA levels in patients with autism spectrum disorder (ASD), affective disorders, multiple sclerosis (MS) and Parkinson’s disease (PD). NonSCFAs yielded less significantly distinct changes in faecal levels of patients and healthy controls, with the majority of findings were derived from urinary and blood samples. Preclinical studies have implicated different bacterial metabolites

Gut microbial ecosystem in Parkinson’s disease: New clinico-biological insights from multi-omics

Biomarkers, Butyrate, Gut Microbiota, Metabolites /

Gut microbial function is altered in PD, characterized by differentially abundant metabolic features that provide important biological insights into gut-brain pathophysiology. Their clinical relevance further supports a role for microbial-metabolites as potential targets for the development of new biomarkers and therapies in PD. CLICK TO REVIEW

Role of HCA2 in Regulating Intestinal Homeostasis and Suppressing Colon Carcinogenesis

Butyrate, Gut Microbiota, Metabolites, Short Chain Fatty Acids, Vitamins / Supplements / Nutraceuticals /

Hydroxycarboxylic acid receptor 2 (HCA2) is vital for sensing intermediates of metabolism, including β-hydroxybutyrate and butyrate. It also regulates profound anti-inflammatory effects in various tissues, indicating that HCA2 may serve as an essential therapeutic target for mediating inflammation-associated diseases. Butyrate and niacin, endogenous and exogenous ligands of HCA2, have been reported to play an essential role
