A team of scientists has examined how younger and older mice heal from wounds and found that more robust senescent cell activation in younger animals helps them heal faster. A double-edged sword Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they...

A paper in Cell Genomics has described how age-related systemic inflammation (inflammaging) is related to epigenetic aging as measured by four established clocks. Tying together two well-known aspects of aging Chronic InflammationChronic inflammation refers to a persistent, low-grade buzz of immune activity that settles into the body without the drama of an infection or obvious...

In Aging Cell, researchers have described how suppressing the ghrelin receptor improves muscle function and fights sarcopenia in older mice. An appetite hormone with negative effects Ghrelin has been well-documented as stimulating both appetite and growth [1]. However, this hormone, which increases with aging [2], has negative effects in older organisms; deleting ghrelin has been...

In Aging Cell, researchers have described how one dermal protein is related to maintaining the populations of fast-cycling skin cells and preserving skin integrity. Not all skin cells are the same The outer layer of the skin (the epidermis) is naturally regenerated by two distinct populations of stem cells: slow-cycling and fast-cycling [1]. The former...

Researchers have found that simultaneously supplying NAD+ through NMN and reducing its loss through apigenin restores muscle function and bone structure to aged mice. A well-documented issue NAD+ is one of the most well-documented compounds in biology, including within the context of aging. Precursor supplementation has been repeatedly documented to have measurable benefits; for example,...

Researchers have discovered a potential treatment for post-operative delirium, which accelerates cognitive decline in older people. A common problem with long-term effects Roughly a quarter of older people suffer from delirium after surgery [1], which rises to around half if the surgery is particularly invasive or high-risk [2]. This increases the length of hospital stays...
