One second, one life: this axiom was true when LEAF was founded, and it remains true today. More than one person a second dies from age-related diseases, not including contagious diseases that youthful immune health would likely have protected them from. Let’s see what progress has been made last month in helping people live longer.

A Metabolic Peptide Improves Cognitive Performance in Mice: Cognitive decline and neurological aging may involve a peptide known as adropin, according to new research. The identification of this link offers a new perspective on the aging brain and points to novel potential therapies.

Gut brain inflammationFecal Transplantation for Alzheimer’s Disease: A recent review published in Cureus shows why fecal microbial transplantation (FMT) might be able to help sufferers of Alzheimer’s disease, showing how tightly the gut and brain are intertwined.

MTOR Inhibition Leads to 30% Life Extension in Progeric Mice: Researchers have created a new mouse model for studying Hutchinson-Gilford progeria syndrome (HGPS) and achieved 30% lifespan extension in these animals by genetically downregulating mTOR.

Muscles in motionBoosting NANOG to Revitalize Muscle Cell Progenitors: Boosting the expression of the transcription factor NANOG reduces markers of cellular senescence in cultured muscle cells and in live mouse models. This holds out the hope that cells could be rejuvenated without reprogramming them to pluripotency, avoiding some of the associated risks such as oncogenicity.

Key Source of Thymic Aging Discovered: Publishing in Nature Communications’ Cell Death Discovery, a team of Chinese researchers has discovered a reason for thymic involution, the age-related decline of the thymus. When thymic epithelial cells (TECs) are dysregulated and the function of the thymus falters, this can lead to both infection susceptibility and autoimmune disorders.

Elderly exercisingMoveAge: A New Movement-Based Biological Aging Clock: Researchers have developed a biological aging clock based on movement data from wearable devices. Using their clock and the same dataset, they identified a few possibly life-prolonging nutrients and drugs.

Association of Walnut Consumption with Total and Cause-Specific Mortality and Life Expectancy in U.S. Adults: Higher walnut consumption was associated with a lower risk of total and CVD mortality and a greater gained life expectancy among U.S. elder adults.

Nicotinamide Riboside Improves Ataxia Scores and Immunoglobulin Levels in Ataxia Telangiectasia: Treatment with NR is tolerated well and associated with improvement in ataxia and serum immunoglobulin concentrations in patients with this disease.

Effect of resveratrol on C-reactive protein: An updated meta-analysis of randomized controlled trials: This meta-analysis demonstrates that resveratrol consumption is effective in lowering the levels of this inflammation-associated protein.

The Effects of Korean Red Ginseng on Biological Aging and Antioxidant Capacity in Postmenopausal Women: KRG significantly increased the mtDNA copy number and total antioxidant status while improving symptoms of fatigue in postmenopausal women.

Lithium can mildly increase health during ageing but not lifespan in mice: Lithium has a narrow therapeutic dose range, and overdosing can severely affect organ health. Within the tolerable dosing range, the researchers found some mildly positive effects of lithium on healthspan but not on lifespan.

DNA methylation age analysis of rapamycin in common marmosets: Overall, the epigenetic clocks developed here for the common marmoset are expected to be useful for age estimation of wild-born animals and for anti-aging studies in this species.

Surrounding Greenness and Biological Aging Based on DNA Methylation: A Twin and Family Study in Australia: Higher surrounding greenness (vegetation) was associated with slower biological aging, as indicated by GrimAge age acceleration, in Australian women.

The association between epigenetic clocks and physical functioning in older women: a three-year follow-up: While GrimAge performed the best, current epigenetic clocks do not provide strong benefits in predicting the decline of physical functioning, at least during a rather short follow-up period and restricted age-range.

Reversible reprogramming of cardiomyocytes to a fetal state drives heart regeneration in mice: Short-term OSKM expression before and during myocardial infarction ameliorates myocardial damage and improves cardiac function.
