Mitochondrial modulator rejuvenates blood stem cells

Sep. 4, 2023
By Nuala Moran
Researchers have demonstrated that inhibiting mitophagy in ‘old’ hematopoietic stem cells (HSCs) completely restored their blood reconstitution capabilities, raising the prospect of addressing the age-related weakening of the immune system that stems from HSCs deteriorating over time.

Neuronal, blood vessel miscommunication affects aging heart: study

Aug. 31, 2023
By Anette Breindl
Throughout the body, the vasculature and the nervous system are fellow travelers. Renaissance physician and anatomist Andreas Vesalius described their proximity on the macroanatomical level in the 16th century, and modern microscopic techniques have shown that it extends into the micrometer range – where there is a blood vessel, there is often a nerve nearby, and vice versa.

Biomarker brainteaser: Aging? Or just changing?

Aug. 30, 2023
By Anette Breindl
“Change is the only constant” is an ageless truth. In the search for age-related biomarkers, it is also a prosaic confounding factor.

Age-related biomarkers will be critical for the development of antiaging therapeutics. “Nobody is planning to do a life span study in humans,” Eric Verdin told the audience at the 10th Conference on Aging Research and Drug Development in Copenhagen on Monday. “Hence the need for … surrogate markers.”

Wound healing chemokine can improve learning and memory in old mice

Aug. 17, 2023
By Subhasree Nag
Scientists have discovered that a small chemokine protein released by activated platelets, platelet factor 4 (PF 4), reduced neuroinflammation, and improved cognition in aged mice. The study was published on Aug. 16 in the online edition of Nature.

Multivariate GWAS IDs healthy aging candidate genes

Aug. 8, 2023
Researchers have used multivariate statistical analysis to identify new genomic loci related to aging, and new potential drug targets. They reported their findings online in Nature Aging on Aug. 7, 2023. Aging is a multifaceted process, and whether it is going well or not is determined by multiple factors. Most aging studies, however, focus on individual aspects of aging.

Innate immune pathway has role in age-related cognitive decline

Aug. 2, 2023
By Anette Breindl
Swiss researchers have gained new insights into the relationship between aging, inflammation, neurodegeneration and cognitive decline. EPFL professor Andrea Ablasser and her team showed that brain aging was driven by microglial activation of the cGAS/STING pathway.

Targeted drug tackles metabolic syndrome symptoms in mice

July 18, 2023
By Jonathan Smith
An oral drug has shown promise for treating metabolic syndrome in mouse models by selectively blocking the production of free radicals in the mitochondria, a research group has found. The study, carried out by a group led by Martin Brand, Professor Emeritus at the Buck Institute for Research on Aging, could lead to treatments that tackle the underlying causes of metabolic syndrome and multiple other conditions linked to aging.

Time flies: a look into aging at a cellular level

June 19, 2023
By Coia Dulsat
The unprecedented rise in life expectancy has made advances in the understanding of biological hallmarks of aging, at both the molecular and cellular levels, essential. A joint effort between Baylor College of Medicine, Genentech Inc., Stanford University and collaborating institutions has led to the release of the first Aging Fly Cell Atlas (AFCA) as a result of a deep dive analysis of 163 different cell types in Drosophila melanogaster, the common fruit fly.

Preventing taurine loss during aging could improve longevity and health span

June 9, 2023
By Mar de Miguel
A nutritional supplement to reduce the effects of aging might not be a pill of eternal youth, but it could reduce many of the problems of getting old while maintaining good health. The first step to achieve this is included in a study led by scientists from Columbia University. They have set their sights on the amino acid taurine.
