Researchers have discovered how and why α-ketoglutaric acid (AKG) affects cellular senescence and how a small molecule may be useful in affecting this process. They published their findings in Cell Reports. A crucial molecule AKG is a major part of multiple fundamental metabolic processes, including the Krebs cycle that mitochondria use to generate energy, and...

In Aging Cell, researchers have published their findings that mice exposed to influenza experience long-term consequences that can be partially ameliorated with senolytics. Post-viral syndromes Long before the spread of the SARS-CoV-2 virus that causes COVID-19, it had been well-established that viral lung diseases such as influenza lead to lasting damage [1, 2]. Increased risks...

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...

In a recent study that included data from humans, mice, and cell culture experiments, researchers demonstrated that gut microbes and their metabolites can profoundly influence the senescence of endothelial cells. They also explored the molecular processes underlying these changes [1]. Senescence in the blood vessels Endothelial cells line the inner surfaces of blood vessels, and...

Screening of a natural compounds library has revealed the senomorphic properties of apigenin. This natural flavonoid also demonstrated rejuvenating effects on many aging-associated molecular features as well as physical and cognitive performance, and it has a beneficial impact on cancer treatment in mice and cells [1]. Drugs for old cells Senotherapeutics are therapeutic agents that...

Scientists from the Lifespan Research Institute have discovered that a subset of T cells effectively targets senescent cells and improves outcomes in a mouse model of idiopathic pulmonary fibrosis [1]. How do we harness the immune system against senescence? Cellular senescence, which occurs when cells subjected to stress stop dividing and start emitting pro-inflammatory signals,...
