The annual Longevity Summit Dublin occurred this June, and we’re bringing you the highlights. Initiated by Aubrey de Gray and Martin O’Dea in 2022, this convention has earned a popularity for combining scientific depth with simply the correct amount of quirkiness over full 4 days of talks, panels, and late-night networking.
One of many Summit’s attribute options is 2 awards: one for lifetime achievement and the opposite for a brand new star within the longevity discipline. Lifespan.io government director Stephanie Dainow was the latter’s first recipient again in 2022.
Sadly, we had been solely capable of cowl among the a number of dozen talks on the convention. Our apologies typically go to the equally worthy presenters who needed to be unnoticed.
Longevity goes mainstream
The primary day started with a “pre-session” earlier than the official opening, and the very first speak set an attention-grabbing tone. It was given by Michael Suk, the newly elected chair of the American Medical Affiliation (AMA)’s Board of Trustees. The AMA is the largest group of medical medical doctors within the US, and having its chief speak at a long life convention is a vital occasion and an encouraging signal of our discipline inching nearer to the mainstream.
Suk, by means of a distant connection, praised the latest scientific advances that deliver us nearer to customized medication that might enable for persevering with healthspan extension. “The work you do right here,” he mentioned, “has the potential to vary lives, to supply hope the place there’s none, and to redefine the way forward for healthcare. Collectively, we’re constructing a future the place expertise and compassion go hand in hand, the place surgical care is not only about precision, however about individuals, and the place the promise of an extended, more healthy life is inside attain for all.”
Microsoft’s taking discover
Suk’s speak was adopted by one other high-profile speaker who doesn’t come strictly from the longevity discipline: Sally Ann Frank, Worldwide Well being and Life Sciences Lead at Microsoft for Startups and the creator of The Startup Protocol: A Information for Digital Well being Startups.
Sally described Founders Hub, Microsoft’s platform for startup acceleration, which incorporates as much as $150,000 in free Azure credit and different perks. She then moved on to clarify how AI will revolutionize healthcare, which has change into a recurring theme each in Dublin and at different longevity conferences.
Inside Microsoft’s Startup Program, a smaller Pegasus Program is nestled to “curate a really small set of startups from key industries like well being and life sciences.” With the Pegasus Program, Microsoft acts as a VC “to search out these actually pivotal, transformational options and speed up their development.”
Sally then gave an summary of Microsoft’s Pegasus portfolio, which incorporates corporations akin to Helfie.ai, the creator of an app that provides early diagnostics of varied circumstances utilizing only a smartphone’s digital camera and microphone.
AI, Sally mentioned, may help us perceive getting older on the molecular degree for every individual, predict future illness states, personalize therapies, develop new medication and therapies, and, importantly, enhance entry to healthcare of underserved sufferers – one thing corporations like Healfie.ai are already doing.
Extra on AI and longevity
The subsequent speaker was one other Microsoft alumnus, Tom Lawry, former Nationwide Director for AI – Well being and Life Sciences on the firm. Tom, too, is the creator of a bestselling e book: Hacking Healthcare. In the present day, he’s managing director at Second Century Tech, an AI consultancy for well being and medical leaders.
Tom began by drawing a line between predictive and generative AI. Whereas, in the present day, the latter is garnering all the eye with ChatGPT and the likes of it, the previous has been utilized in healthcare for no less than 12-15 years. In the meantime, generative AI has seen but to see huge use in healthcare, however its potentialities are limitless.
Whereas many novel applied sciences observe the so-called Gartner’s curve, the place “the height of inflated expectations” is adopted by “the trough of disillusionment,” Tom thinks that AI will escape this destiny and can simply preserve going sturdy, together with in healthcare. One cause is that the quantity of information is rising exponentially, with healthcare really outperforming different fields. In response to Tom, quickly, 30% of all new information generated world wide will likely be associated to healthcare.
On the similar time, AI coaching prices are plummeting, which signifies that “doing attention-grabbing issues with AI” is turning into simpler and far more accessible. “By 2030,” Tom mentioned, “it’s going to most likely be dearer to take a good friend out to lunch than to coach a big information mannequin.”
How will all this influence longevity? Tom highlighted AI’s capability to find beforehand unknown correlations. As an example, deep studying AI was capable of predict diabetes from a chest X-ray – probably the most ubiquitous sort of well being imaging accessible. Nevertheless, in lots of conditions, a mere smartphone digital camera can unlock wonderful diagnostic capabilities. On this regard, Tom talked about AEYE Well being – the primary firm to obtain FDA approval for diagnosing diabetic retinopathy, a number one explanation for blindness, from handheld digital camera photos.
AI will allow us to optimize well being in any respect phases of life, as a substitute of diagnosing ailments which have already developed, often at an older age. Tom talked about analysis that means millennials is perhaps much less wholesome than earlier generations (although that’s debatable), which makes early diagnostics and customized proactive healthcare ever extra essential.
The founders’ phrases
The pre-session was adopted by the official opening and two temporary talks by the organizers – Aubrey de Gray and Martin O’Dea. In his speak, Martin made a case for nonprofits within the longevity discipline, such because the Longevity Escape Velocity Basis (LEVF) that he co-founded with Aubrey.
LEVF’s flagship undertaking is the Robust Mouse Rejuvenation Project (RMR), which assessments mixture therapies in mice. “What’s attention-grabbing about that undertaking apart from the science,” Martin mentioned, “is that no person else would do it, regardless that a baby can perceive its worth.”
Pharma corporations can’t go in that path, as a result of their modus operandi is to search for a single novel intervention in opposition to a single indication. This leaves the essential job of searching for attainable life-extending combos of present therapies to non-profits.
The nonprofit exercise within the longevity discipline should be vastly expanded, Martin argued, and corporations which might be cashing in on the elemental analysis carried out years in the past by noncommercial brokers must be giving again to nonprofits.
The overarching purpose, nevertheless, is to win over the general public sentiment, which, Martin mentioned, requires talking extra boldly concerning the longevity motion’s final purpose: “I feel we have to say extra in a form of a assured, courageous means that it’s the deterioration, it’s the getting older that we wish to deal with.”
Talking subsequent, Aubrey welcomed the contributors and expanded on longevity escape velocity, the idea he has been selling for many years that gave the identify to his basis.
LEV means shopping for time by eliminating age-related harm (one other idea that Aubrey pioneered and is now coming into the mainstream): “If you happen to take somebody who’s, let’s say, 60 years each chronologically and biologically, and also you rejuvenate them fairly effectively in order that they’re again to being biologically 40, then they gained’t be biologically 60 once more till they’re 80.”
Nevertheless, some sorts of harm are tougher to deal with, and they’re going to proceed to build up, however their impact won’t be as devastating as in the present day’s mixed results of all sorts of harm.
Hopefully, throughout these 20 further years of life, geroscientists “may have been persevering with to enhance this rejuvenation arsenal,” Aubrey mentioned. “We will proceed rejuvenating individuals as a result of we may have improved the remedy in order that among the harm that was troublesome to take away is now throughout the scope of the portfolio that we’ve. The thought is that there’s some finite, the truth is fairly modest, minimal fee at which we’d like individuals just like the individuals on this room to be enhancing the comprehensiveness of rejuvenation applied sciences with a view to keep one step forward of the issue.”
For this to work, the longevity discipline should forged a large web, bringing collectively individuals from varied fields, which is what Longevity Summit Dublin is making an attempt to realize.
A job in opposition to AGEs
Revel Prescribed drugs is a type of courageous small corporations to actually boldly go the place nobody has gone earlier than: on this case, in direction of reversing the molecular harm produced by superior glycation finish merchandise (AGEs). Like their identify suggests, AGEs accumulate with age in blood and tissues, inflicting irritation and the stiffening of the extracellular matrix by binding to molecules like collagen.
Aaron Cravens, Revel’s CEO, informed the viewers that his firm is after a selected AGE, carboxymethylysine (CML). It exists in two types: a free kind current in cells and a certain kind that accumulates within the extracellular matrix (for example, in arterial partitions). “The physique has no physiological technique of eradicating this,” Aaron mentioned.
Revel constructed an enzyme engineering platform to develop bespoke enzymes. At the moment, it focuses on eradicating the free-floating type of CML. In response to Aaron, it strongly contributes to irritation, particularly by binding to the RAGE receptor and initiating inflammatory signaling. The particular scientific utility chosen is rheumatoid arthritis, an inflammatory illness, however the firm envisions “crossing over into longevity biotech.”
The free model of CML has been proven to contribute to microglial dysfunction within the mind, which, in flip, is linked to neurodegenerative ailments. “We’re growing enzymes that may particularly reverse these adjustments as they construct up,” Aaron mentioned. “It’s not making an attempt to sluggish or stop, it’s really reversing the harm.”
The corporate has gone a good distance, enhancing their enzymes’ capability to take away CML a million-fold. Aaron admitted that certain CML is a extra hard-to-crack goal, however Revel is making progress. Sooner or later, in addition they hope to deal with much more insidious AGEs, akin to glucosepane.
The oldest of the outdated
In a chat that was much less about cutting-edge science however essential nonetheless, Natalie Coles, the chief phlebotomist and undertaking supervisor for R3Bio, described her work on making a supercentenarian biobank.
Supercentenarians are a really uncommon breed. At any given time, there’s just a few hundred of them on this planet. Their prevalence is rising, however not as quick as that of centenarians (whose inhabitants is booming), highlighting simply how a lot tougher it’s to cross the 110-year line.
In response to Coles, who has been finding out supercentenarians for years, they’re extra biologically homogeneous than centenarians: that means that they possess, to paraphrase a well-liked film, “a really particular set of organic abilities” that enables them to survive the remainder of us – and people options are value finding out in depth.
Coles engages with supercentenarians personally, travelling everywhere in the world to take organic samples from them. Her speak targeted on the intricacies of performing this job and on her interactions with supercentenarians.
The challenges start with validating the age declare. One group that does that is the Gerontology Analysis Group (GRG) (Wacław Kroczek from GRG additionally offered on the convention, detailing the corporate’s validation methodology). For individuals born initially of the earlier century, particularly in underdeveloped elements of the world, correct documentation is perhaps exhausting to search out.
After the declare has been verified, Natalie arrives to gather samples and carry out interviews. All the things needs to be organized as quick as attainable, because the common remaining lifespan for a supercentenarian is only one yr. Lots of Natalie’s sufferers died earlier than she might meet them.
Lower than one tenth of supercentenarians are males, which makes them particularly priceless for researchers. Natalie talked about the robustness of supercentenarians’ immune programs, made evident by the COVID pandemic: many of the supercentenarians who had gotten contaminated survived the illness, and no less than one individual did it twice.
Geroscience is the important thing
Michael Ringel of the Boston Consulting Group talked concerning the latest developments within the longevity discipline. After a long time of not taking geroscience critically, there’s apparently a rising understanding in society that investigating the biology of getting older is the one technique to thrust back the financial threats of inhabitants getting older and to meaningfully improve human lifespan.
If we do nothing, international assets is perhaps devastated by the necessity to take care of the more and more aged inhabitants, exacerbated by slumping start charges. Nevertheless, even a slight slowing of the speed of getting older would deliver unprecedented prosperity, including hundreds of trillions of dollars to the worldwide financial system over the course of a decade.
In the present day’s medication is clearly unable to realize this, because the positive factors in life expectancy for each further greenback spent on healthcare have flattened out. Fortunately, Michael mentioned, “we’ve seen important development in getting older analysis, funding, and new firm formation during the last couple of years.” Growing old analysis is outperforming biomedical analysis normally and mentions of longevity within the media are additionally on the rise.
Importantly, Massive Pharma is lastly taking discover. Quite a few pharmaceutical corporations have partnered with longevity biotech startups engaged on therapies which might be constructed on the ideas of geroscience. Among the many most notable collaborations are those between AbbVie and Google’s Calico, and between Pfizer and Gero. Answering a query from the viewers concerning the seeming lack of output from Calico, which exists since 2013, Michael famous that AbbVie appears joyful concerning the collaboration.
Senescence and mTOR
Lynn Cox from Oxford College is fascinated with mobile senescence. Senescence, she mentioned, could be very tightly related to getting older: “All the issues that drive getting older additionally drive mobile senescence.” On prime of that, senescence is itself a trademark of getting older, contributing to different hallmarks and age-related ailments. The senescent cell burden grows sooner with untimely getting older, and injecting senescent cells right into a wholesome animal accelerates getting older.
Whereas senescent cells are heterogeneous, in addition they “present very marked adjustments in gene expression.” One explicit change during which Lynn could be very is the upregulation of the mechanistic goal of rapamycin (mTOR). Lynn’s group has been working for years on an in vitro mannequin – human pores and skin fibroblasts – which enabled them to dig deep into the molecular points of senescence.
When a cell goes senescent, its mTOR pathways cease reacting to common stimuli akin to amino acid abundance. As a substitute, they’re continually switched on, which is intriguing since mTOR is related to development and senescent cells now not divide. Nevertheless, they develop a lot bigger than non-senescent cells of the identical sort.
First technology mTOR inhibitors, akin to rapamycin, principally act on one among its elements, mTOR complicated 1 (mTORC1). Whereas some scientists are engaged on creating much more particular mTORC1 inhibitors, Lynn’s group has chosen the wrong way: to focus on each mTORC1 and mTORC2. For this, they’re utilizing an investigational drug from Astra Zeneca, AZD8055, an ATP mimetic that competes with ATP for the energetic web site of mTOR.
Persistent mTOR inhibition with this drug vastly elevated fibroblasts’ replicative lifespan, even when administered intermittently to very aged cells. In already senescent cells, the remedy reversed varied phenotypes of senescence. It alleviated age-related telomere loss, cytoskeleton abnormalities, impaired mitophagy, and morphological adjustments.
Lynn’s group discovered that senescent cells are very energetic mitochondria donors. Whereas wholesome cells additionally alternate mitochondria now and again, senescent cells do it far more typically, populating adjoining cells with their broken mitochondria through “nanotubes”, which is perhaps one of many mechanisms of spreading senescence throughout cell populations. This course of was additionally considerably abrogated by the remedy.
Lynn and her colleagues are transferring by means of with a scientific trial of rapamycin in older adults. It’ll ask questions akin to whether or not rapamycin impacts getting older muscle energy and response to resistance train and whether or not it could actually defend the immune system from getting older in vivo in people.
CHIP: Assault of the clones
The Rising Star Award this yr went to Alexander Fedintsev from the Radical Life Extension Group. In his speak, Fedintsev proposed a brand new hallmark of getting older: clonal hematopoiesis (CHIP). Clonal hematopoiesis is a situation during which a single hematopoietic stem cell (HSC) acquires genetic mutations that give it a development benefit, permitting it to increase clonally throughout the bone marrow. This ends in a major proportion of blood cells being derived from this single mutated stem cell fairly than from a various inhabitants of HSCs.
Mutations that improve self-renewal additionally impair HSCs’ capability to provide wholesome blood cells. Therefore, in an evolutionary course of, much less immunocompetent however extra quickly reproducing cells quickly outcompete regular cells, just like how cancerous cells outcompete non-cancerous ones. CHIP can also be related to lymphoid/myeloid bias, during which HSCs preferentially differentiate into myeloid lineage cells (e.g., granulocytes, monocytes) fairly than lymphoid lineage cells (e.g., B cells, T cells). Myeloid bias additionally has a detrimental impact on the immune system.
The prevalence of CHIP rises exponentially with age and causes a major skew in direction of the innate immune response that myeloid cells are related to. Innate immunity is very pro-inflammatory, which is perhaps one of many causes of age-related sterile irritation (inflammaging). As occurs lots in biology, this creates a optimistic suggestions loop, with irritation selling CHIP.
CHIP drastically will increase the danger of ailments: of heart problems by 80%, of blood most cancers by tenfold, and of lung most cancers by 60%. Some analysis signifies that CHIP is perhaps a number one explanation for loss of life in extraordinarily outdated individuals. Clonal enlargement additionally occurs in different cell varieties, akin to in mesenchymal stem cells, and may contribute to atherosclerosis.
At the moment, we don’t have good instruments to fight CHIP. Nevertheless, extended inhibition of the pro-inflammatory cytokine IL-6 has proven some promise, together with in non-human primates. Answering a query about how protected lifelong IL-6 inhibition is, Fedintsev famous that rheumatoid arthritis sufferers obtain such remedy, which solely causes a slight improve in infections however is related to much less CVD danger.

Peter Diamantis on XPRIZE Healthspan
Entrepreneur and philanthropist Peter Diamantis tuned in remotely to speak with Aubrey de Gray about longevity and particularly XPRIZE Healthspan. Peter is Govt Chairman of the Board of XPRIZE Basis, which he launched 30 years in the past. Throughout these three a long time, 30 prizes have been launched in domains starting from house exploration to biodiversity.
Peter and Aubrey reminisced on their first rounds of discussing the opportunity of a long life XPRIZE virtually 20 years in the past. Whereas Peter was already a long life fan, he felt that the sphere was too small, and the time wasn’t proper again then.
It modified a number of years in the past, when the entrepreneur Sergey Younger, Peter’s companion at BOLD Longevity Progress fund, entered the image. Younger, a passionate longevity investor, helped elevate the primary a million {dollars} to develop the concepts for and the design of the longer term prize. With the longevity discipline rising quick, the thought appeared far more believable.
One drawback was the best way to measure success. Ultimately, it was determined to supply the prize to the primary crew that may reverse practical loss as a consequence of getting older. The principle focus is on the domains of cognition, muscle well being, and the immune system. “Minimal is 10 years reversal,” Peter mentioned, “however the purpose is 20 years”. Aubrey de Gray joined the crew as an advisor, and several other benefactors, together with Hevolution basis, helped put collectively the unprecedented prize fund.
Earlier than that, the biggest XPRIZE ($100 million), funded by Elon Musk, was for growing carbon seize applied sciences to assist combat local weather change. Nevertheless, given the immense significance of accelerating healthspan for humankind, the organizers agreed that the brand new XPRIZE ought to symbolically be even greater, and it was set at $101 million.
Musk’s identify having been talked about, Aubrey requested Peter, why doesn’t Musk help longevity? Peter replied that he was capable of finally make Musk extra amenable to the thought of life extension: “Elon feels that science makes progress one loss of life at a time, that individuals have to die with a view to make room for brand spanking new individuals. And I mentioned to him, Elon, nobody at GM needed to die to create Tesla.”
In the present day, the enormous prize is open for functions, and Peter referred to as on scientific groups to register. He’s assured that longevity is on observe to change into one of many greatest markets on this planet. His different name was for billionaires (though there most likely weren’t any within the viewers) to make use of their cash “to make a dent within the universe.”
Professionals and cons of telomere extension
The Lifetime Achievement Award was given this yr to Maria Blasco, a veteran geroscientist whose contribution to the longevity discipline is formidable. After a brief ceremony Maria proceeded to offer a keynote speak on telomeres, the main subject of her analysis for the final three a long time.
On the daybreak of recent geroscience, telomeres captivated the younger discipline’s consideration. Many hopes had been tied to them, and telomere attrition was included within the authentic 9 Hallmarks of Growing old (Maria was a co-author of the seminal Hallmarks paper from 2013).
It turned out that not all the pieces revolves round telomeres, and their function in well being and longevity is complicated and multifaceted. As an example, many sorts of most cancers cells flip telomerase expression again on to take care of the size of their telomeres, guaranteeing steady proliferation.
Maria described among the most essential experiments with telomeres. As an example, telomerase deficiency in mice causes accelerated getting older, whereas transgenic mice with extra-long telomeres stay longer and, importantly, get much less most cancers, which is the main explanation for loss of life in lab mice. These mice additionally confirmed important enhancements in healthspan: higher metabolism, much less cognitive decline, much less osteoporosis, and so forth.
Telomere shortening performs an essential function in lots of ailments, together with the lethal pulmonary fibrosis. Gene remedy with TERT (telomerase reverse transcriptase, a vital telomerase subunit) stops and even reverses pulmonary fibrosis in a mouse mannequin, lowering irritation, harm, and senescent cell burden.
Different circumstances during which quick telomeres are an element embrace kidney fibrosis and myocardial infarction. In a single research, solely mice with quick telomeres developed kidney fibrosis when challenged with folic acid.
One other research that Maria talked about may present an evidence of why turning again telomerase expression appears to decrease the danger of most cancers as a substitute of elevating it: shorter telomeres trigger chromosomal instability, which will increase the danger of oncogenic mutations. Genetically engineered TERT-expressing mice had been extra protected against most cancers even when challenged with oncogenic mutations.
A research from 2020 tied COVID severity to shorter telomeres. One other one, from 2024, detected extra lung fibrosis in COVID survivors with shorter telomeres. Telomeres may not maintain the last word key to life extension, however they definitely play an essential function in getting older and age-related ailments that must be totally investigated.
Eat much less, stay longer
Rozalyn Anderson of the College of Wisconsin Madison reported on one other longevity “staple”: caloric restriction (CR). CR, studied because the mid-Twentieth century, has been proven to enhance healthspan and lifespan in lots of mannequin organisms. There are additionally some preliminary optimistic findings in people. As an example, the CALERIE randomized managed trial confirmed “a persistent and important discount of all measured standard cardiometabolic danger components” on account of long-term 25% caloric restriction (though Rozalyn thinks that as a consequence of weak adherence, the precise CR fee in CALERIE was round 15%).
Caloric restriction impacts many mechanisms of getting older, and Rozalyn’s group is engaged on understanding how precisely this occurs. “Metabolite, power, and oxidation sensors regulate longevity and all have been implicated in CR’s mechanisms,” Rozalyn mentioned. “Metabolism influences all mobile features from info entry to move to motion and development to signaling.” There’s a metabolic element to heart problems, neurodegeneration, most cancers, and diabetes, to call just a few. Unsurprisingly, many geroprotective interventions work alongside the identical pathways that CR does.
Rozalyn informed the viewers concerning the essential and long-running research of CR in rhesus monkeys, that are long-lived and really humanlike animals. They share 93% of their genome with people and have comparable getting older outcomes. 76 monkeys had been recruited for this research within the late 80s / early 90s and monitored for greater than 30 years, and now we’ve lifespan information.
Lifelong 30% caloric restriction had a profound impact on lifespan and survival, reducing the percentages of dying from age-related circumstances by 4.4 instances. The scientists recognized multi-omic CR signatures and recorded some intriguing results. As an example, calorie-restricted animals had much less muscle mass in midlife however extra in late life: they had been partially resistant to age-related loss in each muscle amount and high quality. CR additionally countered the decline in voluntary bodily exercise that’s attribute of outdated age. Each men and women responded to CR, however considerably in a different way.
Constructing a mega-movement
Melissa King has over 20 years of expertise in enterprise, non-profits, and public affairs. About two years in the past, she co-founded Healthspan Action Coalition with one other veteran medical analysis advocate, Bernard Siegel. We excitedly reported on the creation of HAC from Longevity Summit Dublin 2022, welcoming these advocacy heavyweights into our discipline. Since then, the coalition has grown impressively to unite greater than 160 organizations throughout 25 international locations, together with Lifespan.io.
Melissa has steered essential campaigns and initiatives in affected person advocacy and biomedical analysis funding. For instance, she led a profitable poll initiative in California to safe $8.5 billion in funding for the California Institute for Regenerative Medication, which makes a speciality of stem cell analysis.
Affected person advocacy, Melissa argued, is impressively efficient in mobilizing public opinion and funds for well being analysis initiatives. Now’s the time to use the ideas of affected person advocacy to prolonging healthspan. In any case, with regards to getting older, each individual on the planet is a affected person. This creates a possible for a very huge motion.
Whereas we’re all excited concerning the rise of longevity biotech, “public funding for science is what introduced us to house and the moon, enabled medical analysis that introduced us vaccines and different life-saving therapies,” Melissa mentioned. “Non-public business and funding often don’t are available early due to the danger.”
Authorities oversees immense assets, nevertheless it must be steered in the suitable path by public opinion. Whereas many at this and different latest conferences evoked working with public opinion as a vital component of the longevity discipline’s success, Melissa made it the cornerstone of her speak.
Skillful and efficient science communication is the important thing, she mentioned, and we couldn’t agree extra. Melissa referred to as on the members of the geroscience group “to assist the general public by making it some extent to speak with non-scientist family and friends members about science and your work.” This may be performed by writing articles/op-eds for lay audiences, giving talks, and extra.
