The Longevity 2020 Online Conference, to be Held April 27th to May 1st 2020
All of the longevity industry and gerontology conferences in coming months have been cancelled or rescheduled as a result of the present mix of COVID-19 pandemic and hysteria. An equal mix of both, perhaps. The best data to date puts the mortality rate at 0.66% or so, meaning about six yearly flu seasons worth of risk, and even that number is most likely still overstating the risk, as it misses the presently unknown count of infections that result in only minor symptoms. An article from earlier in the month on the uncertainties in all published numbers remains one of the more sane pieces written on the topic. Still,...

Notes on the 2020 Longevity Therapeutics Conference in San Francisco
I recently attended the 2020 Longevity Therapeutics conference in San Francisco. I presented on the work ongoing at Repair Biotechnologies, but as is usually the case the more important parts of the visit took place outside the bounds of the conference proper. Longevity Therapeutics is one of the four or five core conferences for the longevity industry, at which you'll meet many of the early participants - a mix of scientists, entrepreneurs, and investors, and patient advocates. As such, most of the conference goers have already seen my updates, or are otherwise aware of the Repair Biotechnologies programs aimed at thymic ...

This study demonstrates for the first time that senescent cells secrete functional LTs, significantly contributing to the LTs pool known to cause or exacerbate idiopathic pulmonary fibrosis. Against Senolytics https://www.fightaging.org/archives/2019/11/against-senolytics/ There is no consensus in science that is so strong as to have no heretics. So here we have an interview with a naysayer on the matter of senolytic treatments, who argues that the loss of senescent cells in aged tissues will cause more harm to long-term health than the damage they will do by remaining. To be clear, I think this to be a ...

The Strategy of mTORC1 Inhibition Fails a Phase III Trial
The worst possible outcome when developing a clinical therapy is not an early failure. It is a late failure, in the final and most expensive phase III clinical trial, in which the therapy interacts with a sizable patient population, and after a great deal of time and funding have been devoted to the program. This result is far more likely for therapies based on mechanisms that have smaller rather than larger effect sizes, and where that smaller effect size varies from individual to individual for reasons that are not well understood - something that describes all too much of the past few decades of efforts to treat age-rel...

In conclusion, a polypharmacology approach of combining established, prolongevity drug inhibitors of specific nodes may be the most effective way to target the nutrient-sensing network to improve late-life health. Deletion of p38α in Neurons Slows Neural Stem Cell Decline and Loss of Cognitive Function in Mice https://www.fightaging.org/archives/2019/10/deletion-of-p38%ce%b1-in-neurons-slows-neural-stem-cell-decline-and-loss-of-cognitive-function-in-mice/ Researchers here provide evidence for p38α to be involved in the regulation of diminished neural stem cell activity with age. It is thought that the ...

This study elucidates the potential to use mitochondria from different donors (PAMM) to treat UVR stress and possibly other types of damage or metabolic malfunctions in cells, resulting in not only in-vitro but also ex-vivo applications. Gene Therapy in Mice Alters the Balance of Macrophage Phenotypes to Slow Atherosclerosis Progression https://www.fightaging.org/archives/2019/07/gene-therapy-in-mice-alters-the-balance-of-macrophage-phenotypes-to-slow-atherosclerosis-progression/ Atherosclerosis causes a sizable fraction of all deaths in our species.

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 found that professional chess players had shorter lifespans than those players who had careers outside of chess and argued that this might be due to the mental strain of international chess competition. In the present study, we focused on survival of International Chess Grandmasters (GMs) which represent players, of whom most are professional, at the highest level. In 2010, the overall life expectancy of GMs at the age of 30 years was 53.6 years, which is significantly greater than the overall weighted mean life expectancy of 45.9 years for the general population. In all three regions examined, mean life...

Progress in the Creation of a Neoantigen Cancer Vaccine
Targeting therapies to some combination of neoantigens, distinctive markers on the surface of cancerous cells that the immune system learns to recognize, and which vary from patient to patient, represents an advance in the specificity of targeted cancer immunotherapy. It should, in principle, better rouse the immune system to attack cancerous cells, while producing fewer side-effects. Researchers here report on an early human trial of this sort of approach; the initial results look promising, certainly from the perspective of an absence of serious side-effects, though a more robust demonstration of the ability to reduce tu...

This study is the first to show that downregulation of PAPP-A expression in adult mice can significantly extend life span. Importantly, this beneficial longevity phenotype is distinct from the dwarfism of long-lived PAPP-A KO, Ames dwarf, Snell dwarf and growth hormone receptor (GHR) KO mice with germ-line mutations. Thus, downregulation of PAPP-A expression joins other treatment regimens, such as resveratrol, rapamycin and dietary restriction, which can extend life span when started in mice as adults. In a recent study, inducible knockdown of the GHR in young adult female mice increased maximal, but not median, lif...

In conclusion, DNAm of multiple disease-related genes are strongly linked to mortality outcomes. The recently established epigenetic clock (DNAm age) has received growing attention as an increasing number of studies have uncovered it to be a proxy of biological ageing and thus potentially providing a measure for assessing health and mortality. Intriguingly, we targeted mortality-related DNAm changes and did not find any overlap with previously established CpGs that are used to determine the DNAm age. Our findings are in line with evidence, suggesting that DNAm involved in ageing or health-related outcomes are mostly...
