Gut microbes may dictate cellular aging, new review suggests
A Frontiers in Aging review introduces the microbiome‑gerogene axis, proposing that gut microbes act as upstream regulators of cellular aging networks. Age‑related dysbiosis reduces key metabolites, leading to leaky gut, chronic inflammation and epigenetic drift that accelerate organ decline. The authors highlight precision interventions such as ellagitannin‑derived urolithin A and fermentable fibers to restore microbial balance.
Viruses in the Gut May Help Prevent Blood Sugar Spikes, Mouse Study Hints
A mouse study published in Cell Host & Microbe shows that the gut virome—primarily bacteriophages—modulates carbohydrate metabolism by activating immune pathways. Disrupting the virome with an antiviral cocktail caused sharp blood‑glucose spikes in mice fed a high‑carbohydrate diet, while enriching viral loads improved glucose tolerance without changing bacterial communities. The effect is mediated by T‑cell uptake of viral particles, which triggers proteins that limit glucose entry into the bloodstream. Human intestinal organoids reproduced the same virome‑immune‑metabolism interaction, suggesting relevance beyond rodents.
