In a review published in Nature, researchers have explained how and why cells transfer mitochondria to one another, proposing that this transfer allows organisms to be more resilient against energy deficiencies. A relatively recent discovery It was not until 2006 when a team of researchers realized that mitochondria were not restricted to their cellular environments, as...

Scientists have found that leakage of mitochondrial DNA in senescent cells is a major cause of their pro-inflammatory activity, and it can be targeted without clearing those cells out [1]. A new aspect of senescence Why we Age: Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or...

Scientists have reported in Nature Aging that impaired mitochondrial uptake of calcium ions leads to changes in inflammatory responses that resemble what happens in aging [1]. Inflammation and aging Inflammation is an essential, evolutionarily conserved process and a fundamental part of the immune response, providing immediate defense against infections by pathogens such as bacteria, viruses,...

The Journal Club returns on 25th July at 12:00 Eastern time to the Lifespan.io Facebook channel. Editing mitochondrial DNA (mtDNA) has long been a challenge and systems such as CRISPR, which make editing regular DNA faster and easier, are very difficult to use when it comes to mtDNA. This month we are going to take...

Financed by Lifespan.io's crowdfunding efforts, SENS Research Foundation has engaged in fruitful research into ways of dealing with mitochondrial dysfunction, the gradual loss of function of our cells' power plants. Here, the organization reports its successes in handling this aspect of aging. The cellular machinery and higher-level structures of our bodies inevitably damage themselves as...

Researchers publishing in Nature Biotechnology have developed a novel method of editing mitochondrial DNA, which cannot be accomplished with nuclear DNA tools. Where CRISPR doesn't work Why we Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm cells and cause...
