Notes from the Rejuvenation Startup Summit, Held in Berlin in October 2022
We presented recent results showing reversal of liver inflammation and fibrosis in NASH model mice, and noted that we're raising funds to start our clinical development program leading to human trials. Therapies to reverse atherosclerosis progression will follow shortly on the heels of this work on NASH. Robin Mansukhani of Deciduous Therapeutics discussed their approach to immune system modulation via small molecules, training invariant natural killer cells to attack senescent cells. The point was made that engaging the immune system may be a way to work around many of the present unknowns regarding senescent cell ...

Fight Aging! Newsletter, September 26th 2022
This study examined the dose-response association between daily step count and intensity and incidence of all-cause dementia among adults in the UK. This was a UK Biobank prospective population-based cohort study (February 2013 to December 2015) with 6.9 years of follow-up (data analysis conducted May 2022). A total of 78,430 of 103,684 eligible adults aged 40 to 79 years with valid wrist accelerometer data were included. Registry-based dementia was ascertained through October 2021. We found no minimal threshold for the beneficial association of step counts with incident dementia. Our findings suggest that approxima...

Summarizing the State of Aging Research
Providing a summary of the present state of aging research is a tall order, given the rapid growth in the field, and great breadth of work in both academia and industry, but the authors of this lengthy review paper take a swing at it. They look at areas of interest, new and well-established, apply a loose taxonomy to diverse initiatives, and attempt to draw it all together into a cohesive whole. The thrust of the field nowadays is towards intervention, attempting to slow or reverse aging in order to treat and prevent age-related disease. The important debates are over which strategies are more likely versus less likely to ...

Fight Aging! Newsletter, September 19th 2022
Conclusion Use of the Khavinson peptides and melatonin in combination in this way, at this dose, negatively impacts the thymus, producing a reduction in active tissue and increase in atrophy to fatty tissue. The degree to which this atrophy occurred is greater than one would expect to take place over nine months of aging at this stage of life. Why did this outcome occur, given the animal studies showing thymic regrowth, and the studies showing reduced later life mortality following use of thymogen? We can only speculate. Firstly, the dose makes the poison, and the dosing here may have been too high, too frequ...

SENS Research Foundation Annual Reports for 2022
The SENS Research Foundation has published its annual reports for 2022, for those interested. SENS, the Strategies for Engineered Negligible Senescence, is both (a) a laundry list of forms of cell and tissue damage that cause aging, with supporting evidence from the past century of scientific research into aging, and (b) a laundry list methods of intervention that should produce rejuvenation. Aging is damage accumulation, and rejuvenation is repair of that damage. Funding for SENS programs, and initiatives to produce therapies based on the SENS view of damage repair, remain as relevant as ever. In fact, even more re...

Arguing for an Expansion of the Hallmarks of Aging
The hallmarks of aging form a catalog of largely better studied changes in cells and tissues considered relevant, and possibly more important, in the onset and development of age-related degeneration and disease. This is not the same thing as a list of causes of aging. A few of the hallmarks mostly likely are or include deeper causes of aging, or close to causes of aging. The hallmarks do overlap with the SENS description of aging as a set of root causes, forms of molecular damage that result from the normal operation of a youthful metabolism. Since the hallmarks of aging are not, and are not intended to be a list of cause...

Conclusion Coupled with the animal data, and the existing human trial data for safety, the results here suggests that someone should run a formal, controlled trial of flagellin immunization in older people, 65 and over. The goal would be to see whether (a) this sort of outcome holds up in a larger group of people, and (b) there is a meaningful impact on chronic inflammation and other parameters of health that are known to be affected by the aging of the gut microbiome. The most interesting part of the data is perhaps the decline in microbial diversity, when considered against the gains elsewhere. Microbial dive...

Improving Hematopoietic Stem Cell Transplants
One of the causes of immune system aging is the growing dysfunction of hematopoietic stem cell populations, responsible for the production of immune cells. While some of this degeneration comes from the aging of the bone marrow niche, some it appears to be intrinsic to the cells themselves, and thus there may be benefits to be found in transplantation of functional hematopoietic stem cells derived from a patient's own cells. This would be the case if these cells could be made to reliably survive and engraft in any reasonable number, however. That is a challenging prospect, but it is worth keeping an eye on the cancer field...

Connections Between Epigenetic Aging and Nuclear DNA Damage
Today's open access paper reviews what is known of the connections between epigenetic aging and the nuclear DNA damage that occurs across a lifetime, and particularly in later life. Some of this DNA damage is more evidently connected with the epigenetic regulation that determines the packaging and structure of nuclear DNA, such as the activity of transposable elements, restrained in youth, but unleashed to copy themselves in later life, damaging genes as they do so. It is important to note that the relationship of cause and consequence between nuclear DNA damage and epigenetic change is likely a two-way street, particularl...

In conclusion, application of a multi-species bat epigenetic clock provides strong evidence that hibernation is associated with slower epigenetic ageing. The multi-species clock explains 94% of the variation in the chronological ages of both hibernating and non-hibernating big brown bats; however, the clock estimates are equal to or greater than the chronological age, suggesting big brown bats age slightly faster than a 'typical' bat, especially during the active period.
