A new study dives into a human-derived probiotic cocktail meant to protect against Alzheimer’s disease. The treatment improves gut health and reduces inflammation in mice [1]. The earlier, the better Early interventions to prevent or delay Alzheimer's disease might be a more feasible approach than reversing the disease when it is fully developed. However, such...

In Aging Cell, researchers have described how different combinations of gut bacteria impact muscle strength in mice. Expanding upon a known link The link between gut bacteria and health is well-documented, and multiple biomarkers have confirmed that a healthy gut leads to health elsewhere [1]. This is not just due to inflammation caused by pathogenic...

A recent study linked probiotic-induced gut microbiome and metabolite changes to improved muscle functioning in older sarcopenia patients [1]. Sarcopenia and the gut Sarcopenia is an age-related condition. People with sarcopenia suffer from a reduction in muscle mass, strength, and function, leading to a decreased quality of life and increased morbidity and mortality [2]. The...

In a preprint study, scientists from Lifespan Research Institute and the Buck Institute for Research on Aging have published their findings that Urolithin A, a molecule that has garnered a lot of attention in the longevity field, potently reduces senescence-related markers in human fibroblasts [1]. Senolytic versus senomorphic Cellular senescence is a well-documented aspect of...

Fecal microbiota transplantation from young mice to older mice improved multiple metabolic parameters and some hallmarks of aging, such as inflammation and telomere shortening [1]. Bringing back the balance Dysbiosis, an imbalance in the gut microbiome, is a newly recognized hallmark of aging [2]. Dysbiosis elevates the risk of many diseases, including cardiovascular diseases [3]....

The authors of a recent review investigated what is known about gut microbiota in centenarians and how gut microbes can help people achieve extreme longevity [1]. What makes centenarians special? One way of investigating what gives people longevity and health in older ages is to study people who have achieved it, especially those who have...
