Blocking the EP2 receptor restores immune cleanup in aged mice
A Stanford study in aged mice suggests that tissue macrophages lose the ability to clear senescent neutrophils with age, and that blocking the EP2 receptor restored this cleanup, reducing inflammation and preserving organs.
Engineered enzyme reportedly clears sugar damage from donor aorta tissue
A publication cites a Nature Communications study in which an engineered enzyme reportedly removed more than 70% of a sugar-related damage product from donor aorta tissue. It is early tissue research.
Thymulin and immune recovery in aged mice
A social media post reports that the hormone thymulin restored immune function in aged mice and reduced inflammation and tumor growth. These results come from animals, not people.
Thymulin peptide suppresses age-related inflammation in an experimental model
An article citing Eric Topol reports that thymulin, a peptide derived from the thymus, suppressed age-related inflammation and helped protect against cancer in an experimental model. The finding is early and should not be read as a result in people.
Brain immune cells may be replaced by inflammatory cells with age
A study cited in a news article reports that brain microglia may be replaced by inflammatory cells similar to monocytes, linked to changes in DNA methylation, aging and dementia.
Cell Types May Age at Different Rates
A study of 60,542 participants, published in Nature Medicine, built aging clocks for each cell type using blood samples. The article reports that accelerated muscle aging predicted death from any cause better than other measures.
Compound boosts a muscle repair signal in cell and mouse studies
A report on cell and mouse experiments states that lipoic acid trisulfide more than doubled the binding of a muscle repair signal (HGF) to its receptor in laboratory tests. There are no human trials yet.
Cross-tissue map of DNA methylation changes with human aging
A Nature Aging study published in 2026 maps more than 15,000 DNA methylation profiles across 17 human tissues, finding aging signatures shared across tissues and others specific to each tissue.
Aging Markers in Mice Reverse After Separation From Old Blood
A study in the journal Cell Metabolism, conducted in mice, reports that accelerated aging markers in young mice exposed to old blood returned toward normal about two months after the separation.
Azelaic Acid Extended Lifespan in C. elegans Roundworm Study
A study on the roundworm C. elegans found that azelaic acid reduced reactive oxygen species, increased superoxide dismutase activity and extended lifespan, an effect linked to the insulin signaling pathway. The authors suggest it may be an anti-aging candidate.
Blood-based cell-type aging estimates linked to future disease
A study described in a social media post analyzed over 7,000 blood proteins in more than 60,000 people and linked the biological age of cell types to diseases over 15 years.
Osaka University study points to protein AP2A1 in cell aging
Researchers at Osaka University identified the protein AP2A1, which may help determine whether cells stay active or enter senescence, an aged state.
Plasma exchange in older adults linked to younger aging clock scores
A small placebo-controlled trial of 42 older adults linked plasma exchange to aging clock scores that showed a younger biological age. The result is preliminary and the effect is not yet proven.
Resveratrol Linked to Less Skin Thinning in Mice
A study in mice found that resveratrol slowed age-related skin thinning. In human skin cells, lower levels of SIRT1 increased markers of senescence. The results are preliminary and come from animals and cells.
TIMP2 restored brain immune cells in aged mice, study reports
In mice, restoring the TIMP2 protein moved aged microglia away from inflammatory states and improved debris clearance. The results come from animals and have not been tested in people.
DNA methylation clocks: cause or reflection of aging?
A gerontology researcher explains how DNA methylation clocks estimate biological age from specific sites in blood samples, and discusses whether they control aging or only reflect it.
Gut bacterium linked to aging improves signs of aging in old mice
A study of aged mice published in Nature Aging found that an isolated gut bacterium improved intestinal barrier function and inflammation. The authors also observed that this bacterium decreases with age in human samples.
Mouse embryo study links DNA methylation patterns to epigenetic rejuvenation
A study in mouse embryos links patterns of DNA methylation to what is called epigenetic rejuvenation. The authors classify the statistical significance as exploratory, not confirmatory.
Self-contracting muscle implant and health markers in aging mice
A report on a mouse study indicates that self-contracting muscle grafts increased muscle mass, strength and bone density, and reduced fat and inflammation. The results are early, come from animals, and do not yet show whether the effects occur in people.
TIMP2 protein restores some aged brain immune cell function in mice
In 20-month-old mice, restoring the TIMP2 protein moved brain immune cells called microglia away from inflammatory states and improved clearance of cell debris, according to the study. The results come from animals only.
AI-designed drug shifted aging clocks in small lung fibrosis trial
A phase 2a trial of 42 people with idiopathic pulmonary fibrosis treated with rentosertib found that blood-protein aging clocks showed younger ages than placebo, especially at week 4. The findings are early and based on a small group.
Early mouse data on the SL-100 chemical reprogramming cocktail in aging
A conference presentation reported early, unpublished data in rapidly aging mice. Animals given the SL-100 cocktail kept their weight and were less frail than untreated animals.
First human trial of cellular reprogramming targets the eye
A publication reports the first human patient treated with ER-100, an OSK gene therapy aimed at the eye. The initial goal is to assess safety, not to prove benefits.
Inflammation-linked structures in aging cells: a preliminary Harvard lab finding
A Harvard postdoctoral researcher presented at a conference on structures called inflammasome-like bodies, made of three proteins, in aging cells. The work is early and has not yet been published.
