Mission

Since 1974, the mission of the National Institute on Aging (NIA) has been to improve the health and well-being of older Americans through biomedical, social, and behavioral research.

The Institute conducts and supports research on aging through extramural and intramural programs, focusing on aging processes, age-related diseases, and special problems and needs of the aged. The extramural program funds research and training at universities, hospitals, medical centers, and other public and private organizations nationwide. The intramural program conducts basic and clinical research in Baltimore and on the NIH campus in Bethesda, Maryland. NIA also has a broad information program to communicate about research and health with older people, their families, health professionals, researchers, policymakers, and others.

Research Programs

Intramural Research

IRP Laboratories

Laboratory of Cardiovascular Science (LCS)
The overall goals of LCS are: 1) to identify age associated changes that occur within the cardiovascular system and to determine the mechanisms for these changes; 2) to determine how aging of the heart and vasculature interacts with chronic disease states to enhance the risk for CV diseases in older persons; 3) to study basic mechanisms in excitation-contraction coupling and how these are modulated by surface receptor signaling pathways in cardiac cells; 4) to elucidate mechanisms of pacemaker activity in sinoatrial nodal cells; 5) to elucidate mechanisms that govern cardiac and vascular cell survival; and 6) to establish the potentials and limitations of new therapeutic approaches such as changes in lifestyle, novel pharmacologic agents or gene or stem cell transfer techniques in aging or disease states.

Laboratory of Molecular Biology and Immunology (LMBI)
The unifying theme of LMBI's research program is to uncover molecular mechanisms that are pertinent to understanding and ameliorating age-associated disabilities and diseases, with particular emphasis on changes in the immune system. Programs cover fundamental biological questions such as: 1) the study of gene regulatory mechanisms that mediate cellular responses to developmental signals, immune activation and stress stimuli, 2) induction of effective immune responses, including the mechanisms of class switch recombination and somatic hypermutation, and generation and maintenance of memory, 3) the role of telomere length and telomerase activity in lymphocyte function and aging. LMBI programs contain a strong translational component with studies aimed at improving vaccine efficacy in the elderly and examining the molecular and cellular basis of tumor metastasis. A wide variety of in vitro and in vivo models are employed to approach these issues. LMBI also shares a close working relationship with the Baltimore Longitudinal Study of Aging that enables direct application of molecular parameters to the human condition.

Laboratory of Clinical Investigation (LCI)
LCI seeks to understand fundamental metabolic processes that change with aging, to elucidate which alterations are pathological and which are homeostatic as humans age. Investigators in the LCI hope to uncover ways to manage and/or circumvent the pathological alterations so that the health of the elderly stays stable. Studies are performed at molecular, cellular, animal model and human levels. Further, LCI takes a multisystem approach to age related changes because changes in one system lead to adaptive changes in another. Understanding which are adaptive and which are primary is an intense area of investigation using newly developed multidimensional algorithms and computer programs. The areas of most intense investigation within LCI are: pancreatic islet morphology and changes therein with obesity and aging; molecular and cellular changes with osteoarthritis; metabolic causes of neurodegeneration; alterations in drug metabolism with age, development of plant-based compounds as treatments for metabolic conditions. In each of these cases, translational research is far advanced on target compounds that are hypothesized to alter natural history of age-related diseases or are already shown to be beneficial in humans. LCI also carries out proof-of-principle Phase 1 research with index compounds that have been developed in the basic science laboratories.

Laboratory of Epidemiology and Population Sciences (LEPS)
Research in LEPS investigates the causes and consequences of disease and function-specific outcomes that are highly prevalent in the population, including health disparities. The laboratory takes a multi-modality and multi-disciplinary approach that is applied in population-based cohorts developed by LEPS scientists in collaboration with other intra-mural and with extra-mural investigators. Studies are designed to integrate knowledge and identify common behavioral and biologic pathways of disease and function related to the cardiovascular, neuro-cognitive, musculoskeletal, body composition and metabolic systems, and investigate how these are affected by age, health disparities, socioeconomic status, genetic difference, and modifiable risk factors. Common mechanisms of interest include inflammation, metabolic dysregulation, increase in visceral fat and decrease in muscle mass, elevated blood pressure and atherosclerosis. Genetic contributions and their interactions with behavioral and physiologic factors are studied in the context of genome wide association study consortia. Efforts also focus on translation to clinical trials of our findings based on observational studies. In addition, we actively investigate state-of-the-art objective measures that can be applied to population-based samples.  

Laboratory of Genetics (LG)
The LG views aging as an integrated extension of human development, with important genes influencing the course of aging even through action in embryonic and fetal life. The long-term goal is to prevent or ameliorate problems of aging tissues by understanding the normal pathways and genetic disorders that affect development, and to use stem cells to help regenerate tissues. Specific aims include: 1) identification of biomarkers of aging and disease progression with novel pattern recognition algorithms and image informatics systems; 2) investigation of the mechanisms of DNA damage response, chromatin remodeling, and post-transcriptional gene regulation associated with cancer and neurodegeneration; and 3) analyses of genetic factors affecting age-related diseases and conditions, including immunosenescence, in a Sardinian founder population.

Laboratory of Molecular Gerontology (LMG)
The LMG investigates processes and mechanisms such as genomic instability, DNA repair, DNA replication, and transcription with special attention to examining the role of DNA damage accumulation in senescence which is a major molecular change with aging. The Oxidative DNA Damage Processing and Mitochondrial Functions Unit investigates accumulation of DNA damage with aging leads to senescence, mitochondrial dysfunction and age-associated disease. The DNA Repair section investigates the role of human premature aging proteins in preventing early aging. The Repair of Endogenous DNA Damage Section investigates the mechanism involved in base excision repair and the function of individual DNA repair proteins and their interaction. The Telomere Maintenance and DNA Repair Unit studies proteins and functions involved in the maintenance of the chromosome ends, the telomeres. The Gene Targeting Unit is exploring how DNA interstrand crosslinks, very detrimental to cells, are removed from DNA and how this relates to age-associated disease. The Section on DNA Helicases focuses on the roles of DNA helicases in genomic stability.

Laboratory of Neurogenetics (LNG)
The LNG studies neurodegenerative diseases based on a resolution of their genetic etiology. The Molecular Genetics Section is focused on finding genes for neurodegenerative disease; the Cell Biology & Gene Expression Section seeks to develop an understanding of the effects of mutant genes on cell physiology; the Transgenic Unit examines the pathogenesis of neurodegenerative disorders in whole animals and to test potential treatments for the diseases; and the Neuromuscular Disease Research Unit works toward an understanding of the genetic basis of neuromuscular disorders. Underpinning this structure are 3 groups: a Clinical Core whose role is to identify patients with neurological disorders and facilitate collaborations with clinical investigators from around the world, a Computational Biology Core whose role is to facilitate the analysis of laboratory data in the broad context of the wealth of information available through the Human Genome Project and related endeavors, and a Genomic Technologies Group whose role is to leverage and support the most recent genomic approaches.

Laboratory of Neurosciences (LNS)
The LNS seeks to understand the cellular and molecular mechanisms of neural plasticity during aging and to develop novel interventions for the prevention and treatment of neurodegenerative conditions such as Alzheimer's, Parkinson's, and Huntington's diseases, as well as stroke. The LNS has a particular focus on signal transduction pathways that control the development and adult plasticity of nerve cell circuits, and how these pathways are affected by dietary energy intake and exercise in the contexts of aging and neurological disorders.  Examples include: mechanisms regulating neurogenesis and the integration of newly generated neurons into existing neuronal circuits; neurotrophic factor signaling; adaptive stress response pathways; cellular calcium homeostasis; and pathways that regulate neuronal bioenergetics. Using animal models and studies of human subjects LNS investigators are discovering how factors such as dietary energy intake and exercise affect the brain during aging, and they are developing and testing novel interventions designed to optimize brain function throughout the lifespan.

Laboratory of Behavioral Neuroscience (LBN)
The LBN conducts basic and clinical research on individual differences in cognition, personality, and affect; investigates the cellular, neural systems and genetic contributions to variation between individuals in animal models and humans; examines predictors and modifiers of age-related neurodegenerative diseases and age-associated changes in behavior, predispositions, and brain-behavior associations; identifies early markers of Alzheimer’s disease and cognitive decline and examines factors that promote the maintenance of cognitive health, and develops; and validates biomarkers of age-related neurodegeneration to inform diagnosis and therapeutic interventions. Laboratory investigators employ a variety of approaches, including experimental, longitudinal, neuroimaging, biomarker, neuropathological, electrophysical, anatomical, molecular and genetic methods in the analysis of biological and psychological aspects of aging.

Translational Gerontology Branch (TGB)
The research efforts of TGB are focused on improving the health and wellbeing of the elderly population through epidemiological, clinical, and basic research programs, with a special emphasis on longitudinal observations and intervention studies. The TGB is investigating and developing novel strategies and interventions to support healthy aging and the prevention, or delay, of functional decline and age-related diseases. The main research goals of the TGB are to: 1) translate discoveries made from human and model organisms to the basic biology (and vice versa), mainstreaming the “bench to bedside to bench” approach; 2) explore and identify the underlying molecular mechanisms responsible for the functional decline that occurs with age, and 3) develop and test interventions to delay aging processes.

Extramural Research

Division of Extramural Activities (DEA)

DEA manages NIA's grants and training policies and procedures, including oversight of grants and contract administration, scientific review, and committee management functions. It serves as primary liaison for NIA with the NIH Office of Extramural Research and with other Institutes that share research interests. NIA's extramural training programs, career development programs, small business initiatives, and other special programs are managed by DEA. The Division handles scientific integrity and ethical questions in research and manages the National Advisory Council on Aging.

The Scientific Review Branch (SRB) conducts initial peer review of specific research applications assigned to the NIA. These include applications for Centers, program projects, scientific meetings, and training and career development as well as applications responding to initiatives published by NIA. External peer reviewers conduct the reviews.

The Grants and Contracts Management Branch (GCMB) works with scientists and institutional research administrators to issue, manage, and close out awards. The branch has legal responsibility for the fiscal management of the Institute’s extramural grants and contracts.

National Advisory Council on Aging (NACA)

Congress created the National Advisory Council on Aging (NACA) "to advise, consult with, and make recommendations to the Secretary, HHS, the Assistant Secretary for Health; the Director, NIH; and the Director, NIA on matters relating to the conduct and support of biomedical, social, and behavioral research, training, health information dissemination, and other programs with respect to the aging process and the diseases and other special problems and needs of the aged."

The NACA consists of 18 members appointed by the HHS Secretary and 5 non-voting ex officio members. Of the 18 appointed members, 12 are leading representatives of the health and scientific disciplines and are leaders in the fields of public health and the behavioral or social sciences relevant to the activities of the NIA, particularly with respect to biological and medical sciences relating to aging and public health. Six of the members are leaders from the general public in the fields of public policy, law, health policy, economics, and management. The NACA meets 3 times each year.

Division of Aging Biology (DAB)

The DAB plans and supports molecular, cellular, genetic and systems biology research on the mechanisms of aging and age-related conditions through various NIH grant mechanisms and contracts. It also supports biological resource facilities that provide aged animals and banked tissues for use in aging research. The overall goal is to provide a basis for development of preventative and interventional strategies to extend healthy aging. The DAB includes the following programs:

Animal Models supports comparative biology research and development of new animal models for aging research. Current models include rats, mice, birds, fish, rabbits, nonhuman primates, insects, nematodes, various other invertebrates and yeasts, with rodent models of particular interest.

Biological Resources manages biological resources through contracts. It coordinates the aged non-human primate resources and the Intervention Testing Program (ITP), a multi-institutional study conducting research on non-genetic interventions to delay aging in a mouse model.

Cardiovascular Biology supports investigations on the molecular and cellular changes that lead to age-related declines in cardiac and vascular function. Aging is itself the major risk factor for heart disease.

Cell Biology supports research on the age-related changes in cell physiology in microenvironments, cellular senescence, apoptosis, autophagy, cancer, cell-autonomy, cellular structures, signaling mechanisms, and protein homeostasis that might contribute to aging phenotypes.

Endocrinology supports basic research into the causes and effects of age-related changes in the endocrine system, and on aging-dependent changes in cellular responses to endocrine factors.

Genetics supports studies to identify and characterize genes and pathways affecting longevity; genome stability; telomere biology; genomics; epigenomics; and progeroid syndromes, all in relation to healthy aging.

Immunology supports studies on changes in the immune systems of older people that may contribute to the increased incidence of infection including regulation of lymphocyte proliferation, immune specificity, autoimmune disease and other immunopathologies, endocrine control of immune function and interventions to retard and/or correct age-related decline in immune function.

Metabolic Regulation supports research on nutrition and metabolism in relation to aging including age-related changes in intermediary metabolism; mitochondrial (dys) function, and mechanisms by which caloric restriction; free radicals and oxidative stress affect lifespan.

Musculoskeletal Biology supports studies on muscle, bone and cartilage that may have negative effects on health of the elderly (e.g., causes of osteoporosis or sarcopenia).

Stem Cells supports research on changes in stem cells (SC) and SC niches during aging. The emphasis is on identification of factors altering SC function with aging, and the roles of SC both in normal tissue homeostasis and injury.

Tissue Physiology supports investigation of age-related changes that affect the function of liver, digestive, renal, and pulmonary systems.

The Trans-NIH Geroscience Interest Group (GSIG) is directed by DAB and includes representation from 20 NIH Institutes and Centers.  The GSIG is a collaborative framework which promotes identification of innovative approaches to better understand the relationships between the biological processes of aging and age-related chronic diseases and disabilities. The GSIG aims to accelerate and coordinate efforts to promote further discoveries on the common risks and mechanisms behind such diseases, with the goal of resolving health problems among our increasingly older population.

Division of Behavioral and Social Research (BSR)

BSR supports research and research training on the processes of aging at both the individual and societal level. It focuses on how people change over the adult life course and on the societal impact of the changing age composition of the population. BSR fosters research that reaches across disciplinary boundaries, from genetics to comparisons across national populations, and across stages from basic through translational.

BSR has two branches, with substantial interactions between them:

The Individual Behavioral Processes Branch supports research on biopsychosocial processes linking health and behavior, emotional and cognitive functioning, human factors, and integrative approaches to the study of social, psychological, genetic, and physiological influences on health and well-being over the life course.  Vertically integrated studies that run from basic to applied are encouraged, as well as translation in some specific areas. 

  • Behavioral Medicine and Behavior Change focuses on the dynamic interrelationships among aging, health, and behavior, adding an aging perspective to observational studies and interventions dealing with development and maintenance of a wide range of health and illness behaviors. Major research topics include: (1) mechanisms of behavior change; (2) behavior change and lifestyle interventions; (3) disease recognition, coping, and management including physiological consequences of life stresses and burdens; and (4) social, behavioral, and environmental interventions for health promotion, disease prevention, and disability postponement. 
  • Behavioral and Population Genetics of Aging focuses on (1) genetics and genomics of social behavior and social environments; (2) understanding genetic and genomic influences linking social and behavioral processes with aging outcomes; and  (3) understanding the social and environmental contexts in which genetic and genomic factors are expressed and influence social, psychological, and behavioral aspects of aging..  This work includes the integration of genetic methods into population-based research and population genetics of aging. Approaches of interest include quantitative and molecular genetic analysis; epigenetic and gene expression studies; and discordant twin designs. 
  • Cognitive Aging supports studies on changes in cognitive functioning over the life course. Studies are encouraged that: (1) examine the influence of contexts (behavioral, social, cultural, and technological) on the cognitive functioning of aging persons; (2) investigate the effects of age-related changes in cognition on activities of daily living, social relationships, and health status; and (3) develop strategies for improving everyday functioning through cognitive interventions. Major topics include higher-order cognitive processes (such as executive function, problem-solving, decision-making, consumer behavior, driving, and health literacy), memory strategies, perceptual skills, and reading and speech comprehension. Research also explores the role of individual differences in cognitive functioning (e.g., motivation, self-efficacy, beliefs about aging, emotions, sensory limitations, experience, and expertise) and health disparities.  BSR collaborates with the NIA Division of Neuroscience to encourage research at the intersection of behavior and neurocognition.
  • Psychological Development and Integrative Science applies an integrative and life course approach to the study of psychological and behavioral aging. Topics include: personality, emotion, subjective well-being, motivation, self-regulation, social behaviors, social relationships, social cognition, stress and resilience. This includes research combining multiple levels of analysis (e.g., psychological, behavioral, social, neurobiological, neuroendocrine, genetic) and examines reciprocal interactions among these levels, as in the areas of social and affective neuroscience; decision sciences and neuroeconomics; health psychology and psychosomatic medicine.
  • Family and Interpersonal Relationships supports research focusing on family and interpersonal relationships at an individual and dyadic level. Areas of interest include associations between marital and other interpersonal relationships with health and wellbeing; the role of the family and social network on individual health behavior and compliance; the role that friends and siblings play in healthy aging; the development of interpersonal relationships over the lifespan; and intergenerational transmission of social behaviors. Comparative studies and studies that take a lifespan perspective are encouraged.

The Population and Social Processes Branch supports research and research training on the causes and consequences of changes in social, demographic, economic, and health characteristics of the older population. Research is supported on the effects of public policies, social institutions, and health care settings on health, well-being, and functioning —both over the life course and in later years—. International and comparative studies are encouraged. Interdisciplinary and multi-level research is strongly encouraged.

  • Demography and Epidemiology fosters research on trends in functioning, disability, morbidity, and mortality; age trajectories of health; life expectancy and active life expectancy; causes and consequences of changes in the age structure of populations; interactions between health and socioeconomic status over time and across generations; the effect on health of social networks and social contexts; interrelationships between work, family, and health; and the dynamics of disability and frailty.
  • Economics of Aging encourages research on the reciprocal relationships between health and work at older ages; consequences of retirement for health and functioning; effects of aging on economic behaviors; health insurance and health care expenditures; interrelationships between health and economic status; the costs of disability; and interventions drawing on insights from behavioral economics to improve the health and well-being of the elderly. Research also deals with income security of future retirees and determinants of retirement and saving, as they affect the health of aging populations.
  • Health and Long-term Care Systems encourages research on the impact of formal health care and long-term care systems on the health and well-being of older persons. Topics include transitions among settings; hospital-level and regional differences in intensity of care, and end-of-life care trajectories.

Division of Geriatrics and Clinical Gerontology (DGCG)

The DGCG supports research on health and disease in older people and research on aging over the human lifespan, including its relationships to health outcomes. DGCG comprises three major research areas, divided into three division branches—Geriatrics, Clinical Gerontology, and Clinical Trials. Program-wide emphases include research training and career development to attract new investigators to the field of aging and to further the development of active investigators in clinical medicine and biomedical research, and the application of new technologies to expand opportunities for clinical aging research.

Geriatrics focuses on health issues regarding older people. Research emphases include multifactorial geriatric syndromes such as falls, frailty, and various types of disability; effects of comorbidity and polypharmacy; effects of age-related changes on clinical or functional disease outcomes or treatment responses; effects of physical activity on disease and disability in older persons; and the elucidation, diagnosis, and treatment of previously unappreciated pathologic changes in old age (e.g., sarcopenia, vascular stiffening, diastolic dysfunction). The Geriatrics Branch supports the Claude D. Pepper Older Americans Independence Centers (OAICs). The OAICs conduct basic and clinical research to enhance the ability of older people to maintain their independence.

Clinical Gerontology focuses on clinically related research on aging changes over the lifespan. Research emphases include healthy aging across the lifespan (including exceptional longevity); protective factors against multiple age-related conditions; determinants of rates of progression of age-related changes that affect disease risk, particularly those for multiple age-related conditions; menopause and mid-life aging changes; translational human research to follow up findings from basic research on aging; long-term effects of current or new interventions that may be administered over a large part of the lifespan; and long-term effects of physical activity throughout the lifespan.

Clinical Trials plans and administers clinical trials on age-related issues. Research emphases include interventions to prevent or treat “geriatric syndromes,” disability, and complications of comorbidity or polypharmacy; trials to detect age- or comorbidity-related differences in responses to interventions against conditions found in middle age and old age; interventions for problems associated with menopause and other mid- and late-life changes; interventions that may affect rates of progression of age-related declines in function in early and mid-life; and interventions with protective effects against multiple age-related conditions, including intervention studies on the effects of androgens in older men.

Division of Neuroscience (DN)

Organized into three separate branches, this division fosters and supports extramural and collaborative research and training to further the understanding of neural and behavioral processes associated with the aging brain. Research on dementias of old age—in particular Alzheimer's disease—is one of the division's highest priorities.

The Neurobiology of Aging Branch fosters research aimed at understanding how the nervous system is affected by normal as well as pathological aging. Fundamental Neuroscience supports studies on age-related structural and functional changes in brain, cell death mechanisms and selective vulnerability to aging, molecular genetics of brain aging bioenergetic processes, systemic metabolism, cerebrovasculature, glia, neural plasticity, neural stem cells, and neurogenesis. In Integrative Neurobiology, the focus is on age-related research on neural mechanisms underlying changes between organ systems and the CNS, in endocrine and immune functions, and neurodegenerative diseases associated with infectious agents including prions. Sleep and Biological Rhythm encompasses age-related studies of epidemiology, etiology, pathogenesis, diagnosis, treatment, and prevention of sleep disorders of older people; sleep-wake cycles/disordered biorhythmicity and behavioral effects in the aged.

The Dementias of Aging Branch supports studies of etiology, pathophysiology, genetics, epidemiology, clinical course, diagnosis and functional assessment, drug discovery and development, behavioral management, and clinical trials in the dementias of later life, especially Alzheimer's disease.  Basic Research supports examination of molecular, cellular, genetic, systemic, and systems aspects involved in the etiology of Alzheimer's disease and other dementias of aging. Population Studies are supported in the epidemiology of cognitive decline, mild cognitive impairment (MCI), and Alzheimer's disease. Clinical Studies focus on the diagnosis, treatment, and management of individuals with cognitive decline, MCI, Alzheimer's disease and other dementias.  Research on diagnostics is aimed at the development and evaluation of reliable and valid multidimensional diagnostic procedures and instruments including imaging and other biomarkers and clinical and neuropsychological instruments for diagnosis, progression, and response to treatment. Research in the treatment and management of the earliest pathological changes of cognitive dysfunction, MCI, AD, and other dementias seeks to develop the understanding required to slow their course, treat and manage the cognitive and behavioral manifestations, and, ultimately, to delay the onset of and to prevent them .Approaches include clinical trials of pharmacologic agents, behavioral, and environmental interventions, as well as preclinical drug discovery and development studies leading to novel compounds for prevention and treatment of these disorders.  The maintenance of a research infrastructure is critical, and the Research Centers component of this branch supports Alzheimer's Disease Research Centers and Alzheimer's Disease Center Core programs, that provide a multifaceted approach to research, training, and educational activities on Alzheimer's disease and several multi-center collaborative research projects.

The Behavioral and Systems Neuroscience Branch emphasizes research on the neural and psychological mechanisms underlying age-related changes in cognition, emotion, sensory and motor function, from the level of genes to the whole organism, and epidemiological studies of populations. Studies of molecular, structural, and dynamic brain changes, including research on adaptation or plasticity, are of particular interest, as well as interventions to maintain or gain function in older age. A focus on Sensory Processes supports studies on mechanisms of normal aging and disease-related alterations in visual, auditory, somatosensory, vestibular, and chemosensory functions. In an effort to understand Motor Function, research is supported on proprioception, postural control, sensory motor integration, vestibular, and movement disorders in aging, including Parkinson's disease. Efforts in Cognitive and Affective Neuroscience look at cognitive processes, including learning, memory, attention, and language as well as the neurobiology of age-related changes in emotion. Understanding and treating age-related cognitive decline are emphasized. The investigation of the relationship of age-related cognitive dysfunction associated with delirium and dementia is also of interest. The Division of Neuroscience and this branch, in particular, interact and collaborate with the Division of Behavioral and Social Research where psychological science and behavioral neuroscience converge.
