What the Second Geroscience Summit Reveals","description":"\u003cp\u003eHow do chronic diseases—and the treatments used to fight them—affect the aging process itself? This is the question tackled by researchers at the Second Geroscience Summit, held April 13–14, 2016 in New York City, and reported in the Annals of the New York Academy of Sciences. The article examines three diseases—cancer, HIV\/AIDS, and diabetes—and shows mounting evidence that these conditions and their treatments can accelerate biological aging through mechanisms that overlap with the core \"pillars\" of aging, including cellular senescence, telomere shortening, inflammation, and oxidative stress. The findings carry practical implications for patients: early disease can set the stage for premature age-related conditions, treatments themselves can influence how fast our cells age, and lifestyle interventions like those in the Diabetes Prevention Program can powerfully offset these effects, especially in people over 60.\u003c\/p\u003e\n\n\u003ch1\u003eCan Chronic Diseases Speed Up Aging?

But far less research has examined the inverse relationship: \u003cstrong\u003edo chronic diseases and their treatments actually accelerate the aging process?\u003c\/strong\u003e This question was the central focus of the Second Geroscience Summit, held on April 13–14, 2016, in New York City.\n\nThe summit brought together experts from leading institutions, including the National Institute on Aging (NIA), the American Federation for Aging Research, the Genetics Society of America, and the New York Academy of Sciences. The organizing principle was the \u003cstrong\u003egeroscience hypothesis\u003c\/strong\u003e: the idea that aging is the major modifiable risk factor for most chronic diseases. By targeting the fundamental biological drivers of aging, researchers hope to combat not just one disease but multiple chronic diseases simultaneously.\n\nThe conventional view has long treated aging as a nonmodifiable risk factor. That has changed recently, thanks to the recognition among aging biologists of a limited number of \"pillars\" that appear to drive the aging process. These pillars were identified through research based on three classic tenets of aging biology: caloric restriction, cell senescence, and free radicals. While these initial theories have evolved, they have allowed researchers to begin translating findings into pharmacological approaches aimed at these pillars.\n\nThe epidemiological evidence is clear: early exposure to severe diseases and\/or their treatments leads to an acceleration of aging, defined by an increased and premature risk of developing age-related diseases and conditions. The summit's goal was to dig deeper and identify the molecular and cellular mechanisms responsible for these observations—with a particular emphasis on how diseases and their treatments interact with the major pillars of aging.\n\n\u003ch2 id=\"geroscience-multidisciplinary\"\u003eGeroscience as a Multidisciplinary Approach\u003c\/h2\u003e\n\nDr. Richard J. Hodes from the National Institute on Aging explained how geroscience is woven throughout the NIH's organizational structure. The NIA's extramural program is organized around four divisions, each uniquely positioned to advance this field:\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDivision of Aging Biology:\u003c\/strong\u003e Leads geroscience at the NIA, focusing on the basic biochemical, genetic, and physiological mechanisms underlying aging and age-related changes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDivision of Neuroscience:\u003c\/strong\u003e Studies the dementias of old age and the normally aging brain, intersecting with geroscience in areas of disease mechanisms and age-related brain changes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDivision of Behavioral and Social Research:\u003c\/strong\u003e Explores aging at individual and societal levels, including the biological mediators of social stressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDivision of Geriatrics and Clinical Gerontology:\u003c\/strong\u003e Supports research on health and disease in the aged, with a focus on aging-related diseases\u003c\/li\u003e\n\u003c\/ul\u003e\n\nThe NIH comprises \u003cstrong\u003e27 different institutes and centers\u003c\/strong\u003e, and nearly all of them investigate diseases for which aging is a risk factor. Aging-related changes affect bodily functions at every level, from cellular metabolism and inflammatory responses to proteostasis (the maintenance of protein balance) and epigenetic modifications. These changes are collectively known as the \u003cstrong\u003e\"pillars of geroscience.\"\u003c\/strong\u003e\n\nTo raise awareness of aging biology's role in disease, the NIA joined with \u003cstrong\u003e20 other NIH institutes\u003c\/strong\u003e to form the Geroscience Interest Group (GSIG). The GSIG organized the first Geroscience Summit in October 2013, which resulted in papers, a book, and multi-institute funding opportunities. The second summit, reported in this article, followed in April 2016.\n\n\u003ch3\u003eKey Findings Highlighted by Hodes\u003c\/h3\u003e\n\nOne of the most significant NIA-supported findings came from the \u003cstrong\u003eDiabetes Prevention Program\u003c\/strong\u003e studies, led by the National Institute of Diabetes and Digestive and Kidney Diseases. The results showed a particularly profound effect of lifestyle intervention in preventing diabetes in individuals \u003cstrong\u003eover 60 years old\u003c\/strong\u003e, relative to the same intervention in younger participants.\n\nAnother striking finding came from a 2013 study by Bouchlaka and colleagues. A systemic cancer immunotherapy strategy was \u003cstrong\u003e100% lethal to older mice after just 48 hours\u003c\/strong\u003e, while \u003cstrong\u003eall of the younger animals survived\u003c\/strong\u003e and were actually helped by the therapy. This demonstrates the life-saving importance of preclinical testing of therapies in older animals—treatments that work in young bodies may be dangerous in aging ones.\n\nDr. Hodes also highlighted innovative research showing that removal of senescent cells (cells that have stopped dividing) from aging mice through genetic strategies results in enhanced structure and function of muscle and other tissues. These findings in model systems provide a basis for translation into clinical studies.\n\n\u003ch2 id=\"disease-drivers\"\u003eDisease Drivers of Aging: Why Cancer, HIV, and Diabetes?\u003c\/h2\u003e\n\nDr. Felipe Sierra of the NIA explained that while aging is recognized as a major risk factor for most chronic diseases, there is still widespread perception that aging is immutable. As a result, both research and clinical trials often focus on curing or preventing specific diseases rather than addressing aging itself.\n\nThe first Geroscience Summit in October 2013 identified \u003cstrong\u003eseven major pillars of aging\u003c\/strong\u003e, but the door was left open for additional pillars not yet identified. One such underexplored pillar: the appearance of early major diseases and their treatment, which epidemiological studies show can lead to premature or accelerated appearance of age-specific traits, including chronic morbidity.\n\nThree diseases were chosen for focused discussion at the 2016 summit:\n\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eHIV\/AIDS\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDiabetes\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCancer\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ol\u003e\n\nWhy these three? The choice was driven by the need to narrow the scope of discussion, but the issues raised are expected to apply, with modifications, to all or most diseases that leave lasting effects (sequelae) affecting later susceptibility to age-related conditions.\n\nThe summit addressed both the effects of the diseases themselves and the effects of their treatments. An important acknowledgment: people of advanced age are rarely affected by a single chronic disease; they often experience multiple comorbidities. However, the focus was on early disease appearance in relatively young people. In those cases, cancer, HIV\/AIDS, and diabetes are often found alone, and the initial disease is treated vigorously. This has led to important increases in survival—but comorbidities appear later as patients age, reducing \u003cstrong\u003ehealth span\u003c\/strong\u003e, the portion of life spent in good health.\n\n\u003ch2 id=\"what-we-know\"\u003eThe Geroscience Hypothesis: What We Know—and What We Don't\u003c\/h2\u003e\n\nDr. Steven N. Austad from the University of Alabama at Birmingham opened with a powerful observation: \u003cstrong\u003eaging occurs even in the absence of disease\u003c\/strong\u003e. This is demonstrated by the steady decline in performance of the world's best master athletes as they grow older. Yet aging is intimately associated with virtually all fatal diseases of modern life, because it increases vulnerability to disease and compromises the ability to recover.\n\nDr. Austad emphasized that nonfatal maladies of aging deserve attention too. Chronic joint pain, loss of vision and hearing, and muscle weakness have become especially important in recent times. The biomedical community has become successful at delaying death, as shown by steadily rising life expectancy for well over a century. But it has not been successful at delaying aging itself. Consequently, the number of people needing joint replacement for chronic pain, cataract surgery for low vision, or assistance with daily living activities has steadily risen. These chronic fatal and nonfatal maladies have become the \u003cstrong\u003enumber one threat to human health globally\u003c\/strong\u003e.\n\n\u003ch3\u003eThree Critical Unanswered Questions\u003c\/h3\u003e\n\nDespite successes in extending the life of laboratory animals through genetic, dietary, and pharmaceutical interventions—which have revealed key players like \u003cstrong\u003einsulin\/IGF and mTOR signaling\u003c\/strong\u003e in complex molecular networks underlying longevity—Dr. Austad identified three critical questions that remain unanswered:\n\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eDo life-extending interventions extend health, or do they simply delay death?\u003c\/strong\u003e This is perhaps the most important question for translation into human therapies. Extending the unhealthy period of life near its end is not a goal worth pursuing. Recently, assessment of age-related health trajectories has become a major focus of laboratory longevity studies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill life-extending interventions work outside the laboratory?\u003c\/strong\u003e Lab animals are protected from infectious diseases, poor diets, and unpredictable environmental events. Some interventions, such as dietary restriction, appear to compromise resistance to at least some infectious diseases—a substantial consideration in the real world.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill effects observed in short-lived species translate to longer-lived species like humans?\u003c\/strong\u003e Only a fraction of cancer treatments successful in mice have proven therapeutically viable in humans. Similarly, very few Alzheimer's disease therapies have translated from success in mice to success in humans.\u003c\/li\u003e\n\u003c\/ol\u003e\n\nDr. Austad's conclusion was direct: \"There is no way to determine whether this will be true for known interventions in mouse aging without performing the human trials.\" He noted that such trials, involving older participants, would not need to be excessively lengthy to detect whether health is extended. \"Multiple drug candidates have already been identified. It is time for the first clinical trial of putative senescence-retarding therapies.\"\n\n\u003ch2 id=\"telomeres\"\u003eTelomeres and Chronic Disease: A Two-Way Street\u003c\/h2\u003e\n\nDr. Elissa Epel from the University of California, San Francisco, unpacked the role of telomeres—the protective caps on the ends of chromosomes—in the relationship between chronic disease and aging.\n\n\u003ch3\u003eWhat Are Telomeres and Why Do They Matter?\u003c\/h3\u003e\n\nTelomeres are a window into one type of aging: \u003cstrong\u003ereplicative senescence\u003c\/strong\u003e, the inability of dividing cells to continue dividing, and thus the inability of tissue to replenish itself. The most common measure in human studies is the average telomere length in blood, across all immune cells. Telomere shortness is an early risk factor for immune senescence. When telomeres reach a critical shortness, the cell enters either senescence or apoptosis (programmed cell death). The intracellular enzyme \u003cstrong\u003etelomerase\u003c\/strong\u003e can promote telomere lengthening, preventing the age-related shortening that comes with cell division.\n\n\u003ch3\u003eTelomeres Predict Disease in Humans\u003c\/h3\u003e\n\nDamage to telomeres—or the inability to rebuild telomere length after cell division—is thought to be a very common pathway to cell senescence in humans, partly because humans are so long-lived. In lower species, this is less important. Rodents, for example, start with very long telomeres and live shorter lives, so telomere attrition only matters in extreme cases, such as genetic knockouts.\n\nTelomere length is useful in human research because it is:\n\u003cul\u003e\n\u003cli\u003eEasy to measure in population-based studies\u003c\/li\u003e\n\u003cli\u003ePredictive of early onset of diseases of aging, as shown by many meta-analyses\u003c\/li\u003e\n\u003cli\u003eA signal that other likely aspects of cell aging may be present\u003c\/li\u003e\n\u003c\/ul\u003e\n\nShort telomeres are bidirectionally related to other aspects of aging biology. Dysfunctional telomeres impair mitochondria and lead to systemic inflammation. Telomeres also play a direct mechanistic role in aging, as demonstrated by Mendelian randomization studies—a research method that uses genetic variants to examine causal effects.\n\n\u003ch3\u003eDisease Processes May Shorten Telomeres\u003c\/h3\u003e\n\nRobust evidence now shows that telomere shortness \u003cstrong\u003eprecedes\u003c\/strong\u003e the onset of cardiovascular disease and diabetes. Early telomere attrition creates risk for early diseases of aging. But once a chronic disease develops, many aspects of the disease process can promote accelerated telomere attrition.\n\nA common triad underlies many diseases of aging:\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eOxidative stress\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eInflammation\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHyperglycemia\/insulin resistance\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\nDiabetes offers a clear example of this vicious cycle. Once a person has diabetes, impaired beta-cell function and resulting higher levels of these biochemical stressors can further shorten telomeres.\n\nPsychiatric diseases follow a similar pattern. The presence of psychiatric disease is associated with shorter telomeres, particularly for \u003cstrong\u003emajor depression and anxiety disorders\u003c\/strong\u003e. There are dose–response relationships: the longer the duration of depression, the shorter the telomere length. Longitudinal studies are needed to determine the strength of causal directions, but given the high comorbidity of medical and psychiatric conditions, it's important to consider that depression itself may alter aging biology—not just physical disease.\n\n\u003ch3\u003eDisease Treatments Can Speed Up or Slow Down Telomere Attrition\u003c\/h3\u003e\n\nTreatments for diseases may further affect the rate of telomere attrition—either speeding it up or slowing it down:\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatins and possibly metformin\u003c\/strong\u003e may prevent telomere attrition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHighly active antiretroviral therapy (ART)\u003c\/strong\u003e in HIV appears to accelerate telomere attrition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemotherapy\u003c\/strong\u003e can damage telomeres of both cancerous cells and healthy cells\u003c\/li\u003e\n\u003c\/ul\u003e\n\nDr. Epel summarized the situation: while cell aging predicts disease, once disease is present, both disease processes and aspects of treatment can further affect telomere stability and repair, and thus the rate of attrition over time. She added a practical suggestion: \"There is a tremendous amount that could be easily learned by incorporating assessments of cellular aging, such as telomere length, into treatment studies.\"\n\n\u003ch2 id=\"hiv-stress\"\u003eStress and HIV: A Bidirectional Relationship\u003c\/h2\u003e\n\nDr. Gretchen N. Neigh from Virginia Commonwealth University presented on the relationship between stress and HIV infection. Individuals living with HIV face a high stressor burden, which includes:\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal stressors:\u003c\/strong\u003e financial burden and stigma\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal stressors:\u003c\/strong\u003e the presence of the virus itself and the effects of antiretroviral medication\u003c\/li\u003e\n\u003c\/ul\u003e\n\nEvidence of this burden is visible in the \u003cstrong\u003eincreased incidence of stress-related disorders\u003c\/strong\u003e among individuals living with HIV, such as depression and posttraumatic stress disorder (PTSD). The combination matters for survival: one report demonstrated that \u003cstrong\u003ewomen living with both depression and HIV have higher mortality\u003c\/strong\u003e than euthymic (normally mooded) women living with HIV.\n\nDr. Neigh explained the relationship between stress and stressors using an analogy: stress is like a rubber band being stretched. An organism's response to a stressor is the physiological state of stress, and stress is designed to return the organism to homeostasis—the internal balance the body constantly works to maintain. Initially, the relationship between stressors and stress is completely predictable and reversible. The force (stressor) is applied, and the stress response returns the system to homeostasis; the relationship is elastic, or resilient. However, if the stressors are too great or too prolonged, the system's elasticity can be overwhelmed, leading to lasting damage.

This may happen through mechanisms overlapping with core aging pillars, including cellular senescence, telomere shortening, inflammation, and oxidative stress. This can lead to premature age-related conditions, so survivors may need closer monitoring later in life.\u003c\/p\u003e\n\u003ch3\u003eDo treatments for chronic diseases affect how fast my cells age?\u003c\/h3\u003e\n\u003cp\u003eSome treatments may affect cellular aging. Chemotherapy can damage telomeres in healthy cells, and antiretroviral therapy for HIV appears to accelerate telomere attrition. In contrast, statins and possibly metformin may help prevent telomere shortening. Discuss these potential long-term effects with your healthcare provider when making treatment decisions.\u003c\/p\u003e\n\u003ch3\u003eCan lifestyle changes really help prevent diabetes, especially in people over 60?\u003c\/h3\u003e\n\u003cp\u003eYes. The Diabetes Prevention Program studies showed a particularly profound effect of lifestyle intervention in preventing diabetes in individuals over 60 years old, compared with younger participants. This suggests that healthy lifestyle changes are powerful at older ages and can offset some effects of aging and disease risk.\u003c\/p\u003e\n\u003ch3\u003eWhat are telomeres and why are they important for aging?\u003c\/h3\u003e\n\u003cp\u003eTelomeres are protective caps on the ends of chromosomes. Each time cells divide, telomeres shorten. When they become critically short, cells enter senescence or die. Short telomeres are an early risk factor for immune senescence and predict early onset of aging-related diseases such as cardiovascular disease and diabetes.\u003c\/p\u003e\n\u003ch3\u003eCan depression or anxiety affect physical aging?\u003c\/h3\u003e\n\u003cp\u003eResearch suggests they can. Presence of psychiatric disease, particularly major depression and anxiety disorders, is associated with shorter telomeres. Longer duration of depression is linked to even shorter telomeres. In women with HIV, having both depression and HIV was associated with higher mortality than HIV alone, highlighting that mental health matters for physical health.\u003c\/p\u003e\n\u003ch3\u003eWhy might a treatment that works in younger people be risky for older people?\u003c\/h3\u003e\n\u003cp\u003eA 2013 study in mice showed that a cancer immunotherapy was 100% lethal to older mice within 48 hours, while all younger animals survived and were actually helped. This demonstrates the importance of testing treatments in older populations and being cautious about applying results from younger people to older patients.\u003c\/p\u003e\n\u003ch3\u003eIs aging itself considered a modifiable risk factor for chronic diseases?\u003c\/h3\u003e\n\u003cp\u003eThe geroscience hypothesis proposes that aging is the major modifiable risk factor for most chronic diseases. By targeting fundamental biological drivers of aging, researchers hope to combat multiple chronic diseases at once, not just one. This represents a shift from viewing aging as unchangeable to potentially delaying age-related ailments.\u003c\/p\u003e\n\u003ch3\u003eI have cancer, HIV, or diabetes. Could these diseases or their treatments speed up aging, and should I get a second opinion about my treatment plan?\u003c\/h3\u003e\n\u003cp\u003eYes, chronic diseases like cancer, HIV, and diabetes may accelerate biological aging through mechanisms such as telomere shortening and inflammation. Some treatments, including chemotherapy and antiretroviral therapy, may speed up telomere attrition, while statins and metformin may protect it. Because treatments can affect cellular aging, a second opinion can help you weigh the long-term effects of your treatment options.
