A Population Study Correlates Air Pollution with Faster Cognitive Aging
https://www.fightaging.org/archives/2024/04/a-population-study-correlates-air-pollution-with-faster-cognitive-aging/
A number of large epidemiological studies provide evidence for long-term exposure to greater levels of air pollution to accelerate the onset and progression of age-related disease. A few of these manage to control for the tendency for wealthier people to avoid living in areas with higher particulate air pollution, ...

An Interview with Reason of Repair Biotechnologies on Reversal of Atherosclerosis
As some of you may know, I co-founded Repair Biotechnologies with Bill Cherman. The company is presently on the development of a gene therapy approach now demonstrated to rapidly reverse atherosclerosis in mice, the condition in which fatty plaques grow to narrow blood vessels and weaken blood vessel walls. One of the possible approaches to treating aging as a medical condition is to take the list of causes of human mortality, start at the top, and work down. Atherosclerosis is the single largest cause of death in our species, through the rupture of unstable atherosclerotic plaque leading to heart attack or stroke. The bur...

In conclusion, although several clinical trials targeting SnCs are ongoing, various questions about the biology of SnCs remain open, resulting in a gap between molecular and cellular data. Concerning the need, initiatives such as SenNet aiming to create openly accessible atlases of SnCs should contribute enormously to the area. Advances in understanding the subcellular structure, the heterogeneity, and the dynamics of SnCs require the integration of molecular and cellular techniques with data analysis packages to evaluate high throughput evidence from microscopy and flow cytometry. It is also necessary to develop new equip...

An Update on Reversal of Atherosclerosis at Repair Biotechnologies
As some of you know, Repair Biotechnologies is the company I co-founded with Bill Cherman back in 2018. We've been working on an approach to reverse atherosclerosis for much of that time, and matters have progressed through the stage of great data in mice to present preparations for a pre-IND meeting with the FDA. While excess cholesterol has long been understood to be important to the development of atherosclerosis, it turns out that circulating cholesterol bound to LDL particles is less important than the amount of localized excess cholesterol in the liver and blood vessel walls.
Any localized excess of cholestero...

Gene therapy ’ s impact on incurable illnesses
Gene therapy has been used recently to cure previously incurable diseases, including sickle cell anemia. It is a horrible disease that I have seen so many times in the ER that it haunts me at night, especially one patient. He was a sweet man with a loving and patient demeanor who tolerated the agony he

Interview with Stefany Shaheen: Revolutionizing diabetes care through cell therapies
I had the extraordinary opportunity to chat with Stefany Shaheen, the Chief Strategy Officer of Advanced Regenerative Manufacturing Institute (ARMI) and BioFab USA, about the transformative potential of cell therapies for individuals living with diabetes. Stefany shared her remarkable journey, insights on cell therapies’ current status, approval challenges, and how the diabetes community can contribute to advancing research in this field.
A few months before this discussion with Stefany, I had the opportunity to hear Dean Kamen speak at the recent ...

This study supports the proposed model that aging-related loss of colonic crypt epithelial cell AMP gene expression can promote increased relative abundances of Gn inflammaging-associated bacteria and gene expression markers of colonic inflammaging. These data may support new targets for aging-related therapies based on intestinal genes and microbiomes.

Problematic B Cells Accumulate in Visceral Fat and Indirectly Provoke Inflammation
The authors of today's open access paper present an interesting and novel way in which visceral fat tissue provokes chronic inflammation. It has been noted that dysfunctional B cells accumulate with age. Here, dysfunctional B cells of a specific subtype are shown to accumulate in aged visceral fat tissue, acting to provoke other immune cells in visceral fat tissue, such as macrophages, into a more pro-inflammatory state. The researchers demonstrate that removing the B cell population helps to reduce the age-related inflammation generated by visceral fat by removing the contribution to inflammatory macrophage behavior.

Predicting the Order of Arrival of the First Rejuvenation Therapies
It has been going on eight years since I last speculated on the order of arrival of the first rejuvenation therapies. Tempus fugit, and time for an updated version! Eight years is a long enough span of time for the first of those rejuvenation therapies to now exist, albeit in a prototypical form, arguably proven in principle but not concretely. The world progresses but my biases remain much the same: the first rejuvenation therapies to work well enough to merit the name will be based on the SENS vision, that aging is at root caused by a few classes of accumulated cell and tissue damage, and biotechnologies that either repa...

Further Progress Towards Regeneration of Sensory Hair Cells to Treat Deafness
In recent years, researchers have attempted to provoke the regeneration of lost sensory hair cells in the inner ear, a potential treatment for forms of deafness. Various genes related to the creation of these cells during development have been identified, and gene therapy interventions attempted in animal models. Progress has been made, but it is incremental, and the results not yet satisfactory. Noted here is a recent example of this sort of work, in which a cocktail of genes is employed rather than focusing on single gene interventions.
The transcription factors (genes) Gfi1, Atoh1, Pou4f3, and Six1 (known colle...

Optimism on the Timeline for Extending Human Lifespans by 20 Years or More
In the interview noted here, Aubrey de Grey of the Longevity Escape Velocity (LEV) Foundation makes a bold prediction of 12-15 years as to when we might see the advent of the first therapies capable of extending the healthy human life span by a few decades, allowing older people to live long enough to benefit from following improvements to further extend their healthy life spans. It is worth bearing in mind that the creation of novel therapies doesn't mean widespread use or even easy availability of those therapies. Further, it is unlikely that we'll know the effects on human life span of any given combination of novel rej...

An Update on Progress Towards Treating Atherosclerosis at Cyclarity
Today I'll point out an interview with one of the Cyclarity Therapeutics founders, illustrative of the degree to which biotech companies are at the mercy of regulators once they arrive at the clinical stage of development. Cyclarity, formerly Underdog Pharmaceuticals, is a spin-out from the SENS Research Foundation, an organization that aims to clear roadblocks in the translational research needed for the production of rejuvenation therapies. The program that led to Cyclarity was focused on finding a way to clear 7-ketocholesterol from the body. 7-ketocholesterol is a form of oxidized cholesterol, created as a result of ox...
