Gut Microbial Genetic Variation Prolongs Host Healthy Longevity and Remodels Metabolome and Proteome in Drosophila Melanogaster

Advanced Science, EarlyView.
This study reveals that specific genetic variations in gut‐residing Saccharomyces cerevisiae significantly extend healthspan and lifespan in Drosophila melanogaster. These mutants rejuvenate aged intestinal metabolism, upregulate mitochondrial proteins, and enhance energy pathways.

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

Advanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

Engineering Bacteria as Living Therapeutics in Cancer Therapy

Advanced Science, EarlyView.
Through synthetic biology approaches, natural bacteria can be genetically programmed into multifunctional living therapeutics. These engineered bacteria are capable of secreting anti‐tumor factors, displaying tumor‐associated antigens on their surface, or undergoing programmed self‐lysis to release therapeutic cargo.

Smart Gated Hollow Mesoporous Silica Hydrogel for Targeting Endoplasmic Reticulum Stress and Promoting Periodontal Tissue Regeneration

Advanced Science, EarlyView.
The hollow mesoporous silica loaded with quercetin (HM‐QU@PEG) is combined with a thermosensitive anti‐bacterial matrix (TF127) to prepare HQUP@TF127. HQUP@TF127 effectively eliminates excessive ROS, alleviates endoplasmic reticulum stress, relieves mitochondrial calcium overload, and blocks the p53‐dependent apoptotic cascade. Furthermore, it enhances

Polydopamine Nanodots Ameliorate Inflammatory Bowel Disease by Restoring Redox Homeostasis and Intestinal Microenvironment

Advanced Science, EarlyView.
A novel melanin‐based therapeutic composed of ultrasmall polydopamine nanodots is employed as an efficient oral formulation for the targeted treatment of inflammatory bowel disease. The potential therapeutic mechanism of polydopamine nanodots mainly involves the elimination of excessive oxidative stress, the reduction of ROS‐mediated proinflammatory ...

Occurrence and distribution of antibiotic resistance genes in Elymus nutans silage from different altitudes on the Qinghai–Tibetan Plateau

Frontiers in Microbiology
IntroductionAntibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) have attracted more attentions in fermented feed recently. However, little information is available on the occurrence and distribution of ARGs in ensiled forages in ...

Probiotics and allergy [PDF]

Proceedings of the Nutrition Society, 2005
Allergy is caused by an immune reaction that is out of all proportion to the antigenic stimuli. Classical allergy is a type I hypersensitivity reaction mediated by the interaction of mast cells (and eosinophils) coated with allergen-specific IgE and a cross-linking allergen.

Secondary Bile Acids Modified by Odoribacter Splanchnicus Alleviate Colitis by Suppressing Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
In ulcerative colitis, the loss of Odoribacter splanchnicus disrupts a microbiota‐metabolite‐neutrophil axis. Restoring this bacterium boosts lithocholic acid, which suppress neutrophil extracellular trap formation and eases colonic inflammation.
