Multikingdom and functional gut #microbiota markers for #autism spectrum disorder

Associations between the gut microbiome and autism spectrum disorder (ASD) have been investigated although most studies have focused on the bacterial component of the microbiome. Whether gut archaea, fungi and viruses, or function of the gut microbiome, is altered in ASD is unclear. Here we performed metagenomic sequencing on faecal samples from 1,627 children (aged… Continue reading Multikingdom and functional gut #microbiota markers for #autism spectrum disorder

Strain-specific gut #microbial signatures in type 2 #diabetes identified in a cross-cohort analysis of 8,117 metagenomes

The association of gut microbial features with type 2 diabetes (T2D) has been inconsistent due in part to the complexity of this disease and variation in study design. Even in cases in which individual microbial species have been associated with T2D, mechanisms have been unable to be attributed to these associations based on specific microbial… Continue reading Strain-specific gut #microbial signatures in type 2 #diabetes identified in a cross-cohort analysis of 8,117 metagenomes

An ingestible device for #gastric electrophysiology

The ability to record high-quality electrophysiology data from the gastrointestinal tract and enteric nervous system is of use in understanding a variety of disorders and improving healthcare via early diagnosis. However, such measurements remain challenging because electrodes must be implanted surgically or worn on the skin, which results in a trade-off between signal quality and… Continue reading An ingestible device for #gastric electrophysiology

Divergent age-associated and metabolism-associated gut #microbiome signatures modulate #cardiovascular disease risk

Insight into associations between the gut microbiome with metabolism and aging is crucial for tailoring interventions to promote healthy longevity. In a discovery cohort of 10,207 individuals aged 40–93 years, we used 21 metabolic parameters to classify individuals into five clusters, termed metabolic multimorbidity clusters (MCs), that represent different metabolic subphenotypes. Compared to the cluster classified… Continue reading Divergent age-associated and metabolism-associated gut #microbiome signatures modulate #cardiovascular disease risk

Mitochondrial ACSS1-K635 acetylation knock-in mice exhibit altered metabolism, cell senescence, and nonalcoholic fatty #liver disease

Acetyl-CoA synthetase short-chain family member 1 (ACSS1) uses acetate to generate mitochondrial acetyl-CoA and is regulated by deacetylation by sirtuin 3. We generated an ACSS1-acetylation (Ac) mimic mouse, where lysine-635 was mutated to glutamine (K635Q). Male Acss1K635Q/K635Q mice were smaller with higher metabolic rate and blood acetate and decreased liver/serum ATP and lactate levels. After a 48-hour… Continue reading Mitochondrial ACSS1-K635 acetylation knock-in mice exhibit altered metabolism, cell senescence, and nonalcoholic fatty #liver disease

The landscape of rare genetic variation associated with inflammatory #bowel disease and #Parkinson’s disease comorbidity

BackgroundInflammatory bowel disease (IBD) and Parkinson’s disease (PD) are chronic disorders that have been suggested to share common pathophysiological processes. LRRK2 has been implicated as playing a role in both diseases. Exploring the genetic basis of the IBD-PD comorbidity through studying high-impact rare genetic variants can facilitate the identification of the novel shared genetic factors underlying this… Continue reading The landscape of rare genetic variation associated with inflammatory #bowel disease and #Parkinson’s disease comorbidity

Safety and efficacy of faecal #microbiota transplantation in patients with mild to moderate #Parkinson’s disease (GUT-PARFECT): a double-blind, placebo-controlled, randomised, phase 2 trial

Dysregulation of the gut microbiome has been implicated in Parkinson's disease (PD). This study aimed to evaluate the clinical effects and safety of a single faecal microbiota transplantation (FMT) in patients with early-stage PD.MethodsThe GUT-PARFECT trial, a single-centre randomised, double-blind, placebo-controlled trial was conducted at Ghent University Hospital between December 01, 2020 and December 12,… Continue reading Safety and efficacy of faecal #microbiota transplantation in patients with mild to moderate #Parkinson’s disease (GUT-PARFECT): a double-blind, placebo-controlled, randomised, phase 2 trial
