This study, for the first time, shows that transplantation of non-autologous mitochondria from healthy skeletal muscle cells into normal cardiomyocytes leads to short-term improvement of bioenergetics indicating "supercharged" state. However, over time these improved effects disappear, which suggests transplantation of mitochondria may have a potential application in settings where there is an acute stress.

In this study, we found that cofilin competes with tau for direct microtubule binding in vitro, in cells, and in vivo, which inhibits tau-induced microtubule assembly. Genetic reduction of cofilin mitigates tauopathy and synaptic defects in Tau-P301S mice and movement deficits in tau transgenic C. elegans. The pathogenic effects of cofilin are selectively mediated by activated cofilin, as active but not inactive cofilin selectively interacts with tubulin, destabilizes microtubules, and promotes tauopathy. These results therefore indicate that activated cofilin plays an essential intermediary role in neurotoxic signaling th...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an ass...

8 Things Autistic People Wished You Knew about April
Every April, autism takes a center stage in global awareness. All around the world, well-meaning, good-hearted people “Light it up blue” for Autism Awareness Month, and they decorate their social media with the puzzle piece frames and the jigsaw rainbow awareness ribbons.
And, every March, autistic adults are already dreading April. Many of them report feeling traumatized by previous Aprils. They begin to mentally prepare for what is ahead, feeling powerless to stop it. They’re bracing themselves for what is on the horizon.
What autistic people wish their neurotypical allies knew going into April:
We really don’t...

This study did not confirm the hypothesis that ELL individuals have lower polygenic risk scores for cardiovascular-related phenotypes. Only the HDL cholesterol and triglyceride PRS were nominally significantly associated with ELL participants. In contrast and as expected, ELL individuals had higher polygenic risk scores for exceptional longevity (EL). In regards to the associations of the various cardiovascular PRS with EL, no findings survived correction for multiple testing. This is despite validating the utility of the lipid PRS by confirming positive associations with measured lipid levels in our sample. Interestingly,...

This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging.

This article, however, is more of a commentary on high level strategy and the effects of regulation, coupled with a desire to forge ahead rather than hold back in the matter of treating aging, thus I concur with much more of what is said than is usually the case.
For decades, one of the most debated questions in gerontology was whether aging is a disease or the norm. At present, excellent reasoning suggests aging should be defined as a disease - indeed, aging has been referred to as "normal disease." Aging is the sum of all age-related diseases and this sum is the best biomarker of aging. Aging and its diseases ar...

This study shows that some genetic changes linked to cancer are present in surprisingly large numbers of normal cells. We still have a long way to go to fully understand the implications of these new findings, but as cancer researchers, we can't underestimate the importance of studying healthy tissue."

Is Crowdfunding The Grim Future of Health Insurance?
A growing number of people, mostly Americans, is forced to use crowdfunding sites to ask for money to cover medical expenses. While in many cases, the option is a potential source of hope binding people together for a good cause that would otherwise be lost due to financial reasons, the phenomenon also shows the desperate state of a healthcare system where victims of terrible illnesses have to “commodify” themselves on online donation forums. Should it stay that way? Should we fear for a dark future of health insurance in some parts of the world?

This article, unfortunately paywalled, is interesting to note as a mark of the now increasingly energetic expansion of commercial efforts in longevity science. David Sinclair has been building a private equity company to work in many areas relevant to this present generation of commercial longevity science; while I'm not sold on his primary research interests as the basis for meaningful treatments for aging, he is diversifying considerably here, including into senolytics, the clearance of senescent cells demonstrated to produce rejuvenation in animal studies. This sort of approach to business mixes aspects of investing and...
