João Pedro de Magalhães on why we have to rethink getting old and spend money on elementary analysis.
Dr João Pedro de Magalhães, a number one professional in biogerontology and comparative genomics, is on the forefront of analysis exploring the organic determinants of longevity and healthspan. His work has considerably contributed to distinguishing between the drivers and passengers of getting old – a vital distinction for growing efficient longevity interventions. As a speaker at this week’s Global Healthspan Summit (GHS2025), he joined a panel on comparative biology, a discipline that leverages insights from long-lived species to determine mechanisms which may be harnessed to increase wholesome human lifespan.
The panel, Comparative Biology – What Can it Unlock?, explored how finding out numerous species can reveal conserved getting old mechanisms, problem current hypotheses derived from conventional mannequin organisms and enhance translational analysis. With an emphasis on figuring out druggable targets and refining human-animal age equivalencies, the dialogue underscored how cross-species evaluation can inform therapeutic methods. Dr de Magalhães emphasised the significance of the evolution of longevity and using evolutionary genomics to attempt to perceive why people stay so long as we do.
Longevity.Know-how: The comparative biology panel at GHS2025 displays a rising recognition that understanding healthspan requires a broader perspective than typical mannequin organisms permit. By finding out species with distinctive lifespans – such because the bowhead whale or the bare mole rat – researchers can determine organic variations that contribute to longevity and resistance to age-related illnesses. Dr de Magalhães highlighted the significance of distinguishing between causative and incidental getting old elements, advocating for elevated funding in elementary getting old analysis. Forward of the panel, we caught up with him to get his tackle epigenetic clocks, the potential of machine studying to determine lifespan-extending compounds and the drivers of human getting old.
Dr de Magalhães informed us he was wanting ahead to GHS2025, describing it as a “fascinating occasion with main specialists from all around the world.”
“It is going to be vital for networking, establishing new collaborations and partnerships in each academia and business,” he defined, including that he thought it might be significantly beneficial for growing new translational approaches that within the long-term assist obtain actual advantages to sufferers.
De Magalhães’ paper final yr in Nature Genetics mentioned distinguishing between driver and passenger mechanisms of aging. He defined that figuring out the true drivers of human getting old is a problem we should sort out.
“The take house message is that we have to higher perceive what are the drivers of human getting old,” he mentioned. “We nonetheless don’t know why we age, what are the causal mechanisms of getting old. I believe that could be a massive limitation within the discipline, so we have to have larger focus and funding in rising our elementary understanding of the getting old course of.”
2024 was a productive yr for de Magalhães as he additionally revealed (with David Gems and Roop Singh Virk) a paper on epigenetic clocks and programmatic aging. He informed us that the foremost conclusion is that, at the very least to a point, getting old processes derive from programmatic mechanisms that begin early in life.
“In a approach this can be a paradigm shift in that our prediction is that we age not due to inevitable and gradual accumulation of molecular harm however reasonably resulting from gene packages that run-on and turn out to be detrimental later in life,” de Magalhães defined. “Because of this with the intention to delay age we have to change our biology, not simply forestall some types of molecular harm like oxidative harm.”
On the University of Birmingham, de Magalhães’ lab has been utilizing machine studying to foretell lifespan-extending compounds in mice. He informed us that he and his workforce have recognized a number of promising longevity compounds primarily based on machine studying predictions, a few of which they’ve validated experimentally and present that they lengthen lifespan in animal fashions.
“Considerably rilmenidine extends lifespan in worms and seems to imitate the advantages of caloric restriction,” he mentioned. “Due to this fact, we’re very fascinated with finding out this compound in mammalian fashions, reminiscent of mice, and ideally carry out a small medical trial to assay its advantages. He added that provided that rilmenidine is already used within the clinic to deal with hypertension, his lab wish to do a small medical trial to assay whether or not it’ll have broader well being advantages in human beings past hypertension. “Extra not too long ago we recognized an extra set of geroprotective compounds utilizing human and mouse information, which we’d love to check experimentally and are open to collaborations.”
Yesterday’s panel touched on the concept that the combination of computational biology and genomics is prone to speed up discoveries in healthspan extension, and de Magalhães informed us that analysis is already making use of those strategies – and their significance and affect will proceed to develop sooner or later.
“Given the complexity of human biology and of getting old, and the way a lot information we’re producing within the life sciences, computational approaches and machine studying/AI play an important function in tackling this inherent complexity and permitting us to achieve new insights as effectively predict the most effective targets and molecules for intervening in getting old and preserving well being.”
