The Inaugural Rejuvenation Startup Summit 2022, brought to you by the Forever Healthy Foundation, took place with over 400 participants from over 30 countries in October. It is a vibrant networking event that aims to accelerate the development of the rejuvenation biotech industry. The Summit brings together startups, members of the longevity venture capital / investor ecosystem, and researchers interested in founding or joining a startup – all aiming to create therapies to vastly extend the healthy human lifespan. We started to publish videos with a first set of selected speakers on the 2022 summit:
Foresight Institute advances technologies for the long-term future of life, focusing on molecular machine nanotechnology, biotechnology, and computer science.

ROS are short lived molecular species containing an unpaired electron which makes them highly reactive as they search for another electron to pair with, and in the process can damage biomolecules such as DNA, proteins and lipids54. ROS induced oxidative stress is known to have multiple deleterious effects on host cells55. However, we have reported that, paradoxically, when ROS is artificially generated outside the cell in the extracellular spaces of the body, they can have wide ranging therapeutic effects18,19,20,26,27. Admixing R with Cu leads to generation of oxygen radicals by virtue of the ability of R to reduce Cu (II) to Cu (I)23,25. Oxygen radicals that are generated in the stomach upon oral administration of R–Cu are apparently absorbed to have systemic effects in the form of deactivation/eradication of extracellular cfChPs. We have shown that cfChPs have wide-ranging damaging effects on host cells. For example, cfChPs can readily enter into the healthy cells to damage their DNA, activate inflammatory cytokines and promote apoptosis via the mitochondrial pathway13,14. Given that 1 × 109–1 × 1012 cells die in the body every day56,57, we have hypothesised that repeated and lifelong assault on healthy cells by cfChPs derived from the dying cells may be the underlying cause of ageing15,16. In support of this hypothesis we show in this article that prolonged oral administration of R–Cu to ageing mice down-regulated multiple biological hallmarks of ageing and neurodegeneration by virtue of its ability to deactivate cfChPs. Our results suggest that R–Cu may qualify as an ideal anti-ageing agent since it has the potential to simultaneously retard or delay the many conditions that are associated with ageing2. To be globally applicable, an ideal anti-ageing agent should also be inexpensive and non-toxic—the two criteria that are also met by R–Cu. The latter can be easily administered orally, and both R and Cu are already approved for human use. An illustrated summary of the study design and the mechanisms by which R–Cu generated oxygen radicals eradicate cfChPs from brain micro-environment leading to down-regulation of ageing hallmarks is provided in Fig. 10.
The mechanism(s) by which R–Cu down-regulates the multiple biological hallmarks of ageing and neurodegeneration needs elaboration. Reversal of telomere shortening by R–Cu may suggest that telomere shortening could be a consequence of DNA damage inflicted by cfChPs which shear off telomere ends causing them to shorten. We observed differential effects between female and male mice with respect to telomere abnormalities. R–Cu effects in preventing telomere abnormalities in female mice were statistically significant for all parameters tested, while this was not the case in male mice. The biological explanation for this discrepant finding remains to be determined. Breakage of telomere ends may also help to explain our detection of persistent γ-H2AX signals in telomere regions of brain cells (DNA-SCARS)—an established signature of senescence43. The bare chromosomal ends can fuse with each other to lead to chromosomal instability and aneuploidy48, as was detected in our study.
Just a quick vid. He mentions the hope of replacing current gene therapy with a pill or three which I heard Cynthia Kenyon say many years ago.
Dr David Sinclair talks about longevity genes, genes therapies and his works on resetting the eyes in this short clip.
David Sinclair is a professor in the Department of Genetics and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School, where he and his colleagues study sirtuins—protein-modifying enzymes that respond to changing NAD+ levels and to caloric restriction—as well as chromatin, energy metabolism, mitochondria, learning and memory, neurodegeneration, cancer, and cellular reprogramming.
Dr David Sinclair has suggested that aging is a disease—and that we may soon have the tools to put it into remission—and he has called for greater international attention to the social, economic and political and benefits of a world in which billions of people can live much longer and much healthier lives.
Dr David Sinclair is the co-founder of several biotechnology companies (Life Biosciences, Sirtris, Genocea, Cohbar, MetroBiotech, ArcBio, Liberty Biosecurity) and is on the boards of several others.
Alzheimer’s disease (AD) is a debilitating progressive illness that begins with mild memory loss and slowly destroys cognitive function and memory. It currently has no cure and is predicted to affect over 100 million people worldwide by 2050. In the United States, AD is the leading cause of dementia in older adults and the 7th most common cause of death, according to the National Institute on Aging.
Ongoing Alzheimer’s research is focused on two key neurotoxic proteins: amyloid beta (Aβ) and tau. Although these proteins have been shown to be associated with AD, the levels of Aβ and tau do not consistently explain or correlate with the severity of cognitive decline for some people with the disease.
Investigators at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, set out to identify other proteins that may be directly involved with fundamental aspects of AD, like synaptic loss and neurodegeneration. They exposed laboratory neurons to human brain extracts from about 40 people who either had AD, were protected from AD despite having high Aβ and tau levels, or were protected from AD with little or no Aβ and tau in their brains.
The discovery that earned Japan’s Shinya Yamanaka the 2012 Nobel Prize in Medicine has paved the way for new research proving that aging is a reversible process. Currently just being tested on lab mice, will the cellular reprogramming soon offer eternal youth?
