Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

Integrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes

The FEBS Journal, EarlyView.
C‐type lectins (CTLs) are involved in the detection of viral/microbial carbohydrates. We studied a family of soluble CTLs in the mosquito Aedes aegypti, which acts as a vector for viruses like dengue and Zika. Using crystallography, biophysics, and structure prediction approaches, we found that these proteins consistently pair together in the same ...

Four Haylages, One Metabonome: Defining Diet Driven Metabolic Shifts in Ponies

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Haylage is widely fed to all categories of stabled horses across Europe and New Zealand. Haylage can vary from high energy nutrient dense forage to low energy highly fibrous fodder, yet little is known about the impact different haylages have on metabolism in horses.

Periodontitis and Inflammatory Bowel Diseases: Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review aims to provide a conceptual framework for understanding the mechanistic interplay between periodontitis and IBD, with a particular emphasis on the microbial and immunological crosstalk linking the oral cavity and the gastrointestinal tract.

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.

Plasma trimethylamine N-oxide (TMAO): associations with cognition, neuroimaging, and dementia

Alzheimer's Research & Therapy
AbstractBackgroundThe gut-derived metabolite Trimethylamine N-oxide (TMAO) and its precursors - betaine, carnitine, choline, and deoxycarnitine – have been associated with an increased risk of cardiovascular disease, but their relation to cognition, neuroimaging markers, and dementia remains uncertain.MethodsIn the population-based Rotterdam Study, we ...

The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

Molecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...

Effects of Weight Loss Interventions on Gut Microbiota‐Derived Metabolites Linked to Cardiometabolic Health: A Systematic Review and Meta‐Analysis

Obesity Reviews, EarlyView.
ABSTRACT Background Gut microbiota‐derived metabolites are emerging as potential mediators between obesity and cardiometabolic conditions. While weight loss interventions modify microbiota composition, their effects on systemic microbial metabolites remain unclear.

Metabolic pattern across energy imbalance: An exploratory metabolomics study of female body weight extremes including anorexia nervosa and athletes

Experimental Physiology, EarlyView.
Abstract In anorexia nervosa (AN), prolonged metabolic adaptation to severe energy deficiency can impair treatment efficacy. Similarly, low energy availability poses a recognized risk to athletes, potentially compromising health and performance. This cross‐sectional study aimed to characterize the plasma metabolic pattern of females with varying ...
