Exercise enhances aged chondrocyte health through microRNA-29-enriched extracellular vesicles

Nature aging · September 29, 2026 · Iijima H, Dave KM, Wang K et al.

DOI: 10.1038/s43587-026-01225-9 · PubMed

A 3-month aerobic exercise intervention in older adults increased microRNA-29 in circulating extracellular vesicles. In vitro, these exercise-primed EVs de-repressed the klotho gene and restored a more youthful chondrocyte phenotype; engineered EVs replicated this, and administration into aged mice improved cartilage health. This links exercise to a specific EV-microRNA-klotho mechanism, supporting exercise as an accessible intervention for joint/tissue aging, though direct clinical cartilage outcomes in humans remain untested.

Multi-modality profiling identifies Neisseria flavescens as a central geroprotective oral commensal in humans

Nature aging · September 24, 2026 · Chen J, Ren Y, Zhou Y et al.

DOI: 10.1038/s43587-026-01220-0 · PubMed

Using multi-modality aging clocks and in silico screening in human data, researchers identified the oral commensal Neisseria flavescens as associated with slower biological aging. Live bacteria extended lifespan/healthspan in C. elegans, and heat-killed supplementation in aged mice restored serum metabolome, liver transcriptome, and gut microbiome toward younger states. This nominates a specific, identifiable oral microbe as a candidate geroprotective target, offering a novel, testable avenue for microbiome-based prevention strategies pending human trials.

Periodontitis, Edentulism, and Accelerated Biological Aging: A Population-Based Study of Epigenetic Clocks

Journal of periodontal research · September 23, 2026 · Chen YN, Wang L, Romandini M et al.

DOI: 10.1111/jre.70163 · PubMed

In a population-based NHANES cohort of 1,926 adults aged 50+, severe periodontitis and edentulism were associated with accelerated epigenetic aging across multiple DNA-methylation clocks (PhenoAge, Hannum, GrimAge2Mort, Horvath), with effect sizes of roughly 1-2 years acceleration. This supports oral health as a modifiable, accessible marker/contributor to biological aging, reinforcing dental care and periodontal treatment as a practical component of personal prevention strategies for healthspan.

Key takeaway for personal prevention

This period's evidence is modest and mostly preliminary. The strongest human finding is a cohort study (NHANES, adults 50+) linking severe periodontitis and tooth loss to modestly accelerated epigenetic aging - an association, not proof of causation. This supports discussing routine dental care and periodontal treatment with a dentist or clinician as a general, low-risk health habit. Two other findings are not yet actionable for prevention: a small human exercise study showed exercise alters a blood signaling molecule tied to a youth-related gene in lab experiments, but this was not tested as a clinical outcome; and an oral bacterium linked to slower biological aging markers in humans was only tested for lifespan/health effects in worms and mice, not people. These animal/cell findings should not be treated as treatments to pursue. Overall, maintain general healthy habits like regular exercise and dental hygiene, as supported by broader evidence, and discuss any specific concerns about aging biomarkers with a qualified clinician rather than acting on early-stage lab findings.
