Telomerase Gene Therapy Treats Neurodegeneration in Mice
Researchers have been testing telomerase gene therapies in mice for more than a decade now, demonstrating extension of life, improved stem cell and tissue function, reduced cancer incidence, and so forth. The research results here, treating neurodegeneration in mice, are a representative example of the sort of work that has emerged in recent years. Telomerase primarily acts to lengthen telomeres, the repeated DNA sequences at the ends of chromosomes. Telomeres shorten with each cell division, a part of the mechanism determining the Hayflick limit to cell replication. Thus the general upregulation of telomerase should resul...

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...

A Conservative View of the Present State of Senolytic Development for Rejuvenation
Here, one of the leading researchers working on the biochemistry of senescent cells - and their relevance to aging - considers the state of development of senolytic therapies. These are treatments, largely small molecule drugs at this stage, but also including suicide gene therapies, immunotherapies, and more, that are capable of selectively destroying some fraction of the senescent cells present in old tissues. There is tremendous enthusiasm in the scientific and development communities for the potential to create significant degrees of rejuvenation via this approach. The results in mice are far and away more impressive a...

Journalists Have Very Fragmentary, Incomplete Views of the Longevity Industry
The lengthy and somewhat overwrought article I'll point out today is a good example of the way in which journalists fail when writing on the topic of the growing biotechnology industry that is making the first steps towards the medical control of aging. They talk to just a few people, and thus have a very narrow (generously) or absolutely incorrect (more accurately) view of what might be happening, the prospects for the future, and the shape of the field as a whole. In this case the few people are the folk at AgeLab at MIT, and George Church, with a focus on the veterinary deployment of gene therapies by Rejuvenate Bio, an...

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...

In this study, we report the age-associated differences between fetal MSC (fMSC) populations and MSCs isolated from elderly donors with respect to their transcriptomes. We successfully reprogrammed fMSCs (55 days post conception) and adult MSC (aMSC; 60-74 years) to iPSCs and, subsequently, generated the corresponding iMSCs. In addition, iMSCs were also derived from ESCs. The iMSCs were similar although not identical to primary MSCs. We unraveled a putative rejuvenation and aging gene expression signature. We show that iMSCs irrespective of donor age and cell type re-acquired a similar secretome to that of their parent...

In this study, we found that senescent chondrocytes isolated from OA patients secrete more EVs compared with nonsenescent chondrocytes. These EVs inhibit cartilage ECM deposition by healthy chondrocytes and can induce a senescent state in nearby cells. We profiled the miR and protein content of EVs isolated from the synovial fluid of OA joints from mice with SnCs. After treatment with a molecule to remove SnCs, termed a senolytic, the composition of EV-associated miR and protein was markedly altered. The senolytic reduced OA development and enhanced chondrogenesis, and these were attributable to several specific differenti...

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,...

In conclusion, long-term aerobic exercise appears to attenuate the decline in endothelial vascular function, a benefit which is maintained during chronological aging. However, currently there is not enough evidence to suggest that exercise interventions improve vascular function in previously sedentary healthy older adults.

From Human To Cyborg: Are You Willing To Augment Your Body?
What if you could have a heat-map vision to search
through an abandoned terrain? What if you could filter out unpleasant odors of
urban decay every now and then? Can you imagine hearing ultrasounds better than
bats? And what about lifting 20 tons or having a third, bionic arm? With the
rapid advancement of technologies, the future of healthcare might not just be
about being healthy, but even augmenting our bodies and “upgrading” ourselves.
Where would you draw the line between being a human and a cyborg?
Superhuman traits in sight: perceiving colors as sounds
The
wish for a perfect human body with enhanced capabi...

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.
