Researchers publishing in Aging Cell have used single-cell transcriptomics to discover new insights into how neural stem cells (NSCs) change with aging. Adults do generate neurons The adult brain does generate new neurons [1], particularly in the hippocampus, the part of the brain responsible for memory formation [2]. Neurogenesis is limited to very specific niches,...

Researchers have discovered that intermittent fasting increases myelin in aged mice, leading to better neural function and coordination. Crucial proteins and a well-known intervention Normally, neuronal axons are coated in a protein sheath made of myelin, which is necessary for their proper function [1]. Myelination is most known to be impeded by multiple sclerosis, but...

Scientists have shown that long-term intermittent reprogramming limited to hippocampal neurons increases their fitness and improves cognitive function in a mouse model of Alzheimer’s disease [1]. Targeted in time and space Partial cellular reprogramming is one of the hottest directions in longevity research for a reason: it allows to rejuvenate cells without driving them all...

In Aging Cell, researchers have identified a receptor in the brain that appears to be responsible for cognitive problems after surgery, particularly in older people. Surgery can cause cognitive problems Neurological symptoms such as postoperative cognitive dysfunction [1] and postoperative delirium [2] are common after surgery, particularly when the surgery is intensive or the patient...

Scientists have found that partial cellular reprogramming, both full-body and restricted to specific brain regions, rescues neurogenesis in the brains of old mice [1]. Cells going back in time Yamanaka Factors - Opportunities for RejuvenationDrs. Takahashi and Yamanaka showed that they could use Oct4, Sox2, Klf4, and c-Myc (OSKM) to reprogram cells back to pluripotent, embryonic...

In Cell, researchers have published a paper outlining the different ways in which brain cells slowly mutate with aging. The genomic damage of aging Cells accumulate mutations with aging, including brain cells [1]. However, as these researchers note, most previous research into these mutations has been on neurons rather than the glia, the helper cells...
