Scientists have discovered that a rare mutation protects against Alzheimer’s disease by dampening a central inflammatory pathway. They recapitulated these results using a small molecule [1]. The woman who beat the odds For the last 40 years, scientists have been studying a massive extended family of about 6,000 people in and around Medellín, Colombia. Many...

Researchers publishing in Cell Reports Medicine have taken a look at what causes CRISPR/Cas9 gene-editing technology to drive cells senescent and investigated a potential method of preventing it. Breaking and repairing DNA Genetic engineering of living cells through CRISPR/Cas9 technology requires three things to occur. The DNA must be disconnected in a double-strand break, new...

A new study defines the concept of immune resilience and positions it as a central determinant of aging trajectories, linking it to survival, inflammation control, and the body’s ability to withstand stress [1]. Keeping the balance Geroscientists have long suspected that the immune system plays an outsized role in aging, one that has deep evolutionary...

In the Journal of Translational Medicine, researchers have published the results of a randomized, controlled clinical trial demonstrating that plasma proteins from young donors have beneficial effects against inflammation in a surgical context. From parabiosis experiments to the clinic Why we Age: Altered Intercellular CommunicationAltered intercellular communication, as described in the Hallmarks of Aging, is...

A reanalysis of data from a previous study identified a difference between people with low and high levels of inflammatory biomarkers. The cognitive performance of people with high levels of inflammation improved after they consumed anthocyanin supplements [1]. Inflammation and dementia Dementia is a complex disorder that involves multiple biological processes, including neuroinflammation. Previous research...

A researcher publishing in Biogerontology has reviewed the literature on the relationship between cellular senescence and the immune system, finding that dwindling immune surveillance allows senescent cells to accumulate. The immune system needs to be deadly On the cellular level, the bodies of vertebrates are brutal police states. Immune cells report, attack, and kill anything...
