Abstract
Aging is characterized by deleterious immune and metabolic changes, but the onset of these changes is unknown. We measured immune and metabolic biomarkers in adults beginning at age 30. To our knowledge, this is the first study to evaluate these biomarkers in adults aged 30 to over 80. Biomarkers were quantified in 961 adults. Tumor necrosis factor alpha (TNF-α), tumor necrosis factor receptor I (TNFR-I), tumor necrosis factor receptor II (TNFR-II), interleukin (IL)-2, IL-6, VCAM-I, D-Dimer, G-CSF, regulated on activation, normal T cell expressed and secreted (RANTES), matrix metalloproteinase-3 (MMP-3), adiponectin, and paraoxonase activity were measured by ELISA. Acylcarnitines and amino acids (AAs) were measured by mass spectrometry and reduced to a single factor using principal components analysis (PCA). Glycine was analyzed separately. The relationship between age and biomarkers was analyzed by linear regression with sex, race, and body mass index (BMI) as covariates. Age was positively correlated with TNF-α, TNFR-I, TNFR-II, IL-6, IL-2, VCAM-1, D-Dimer, MMP-3, adiponectin, acylcarnitines, and AAs. Age was negative correlated with G-CSF, RANTES, and paraoxonase activity. BMI was significant for all biomarkers except IL-2, VCAM-1, RANTES, paraoxonase activity, and the AA factor. Excluding MMP-3, greater BMI was associated with potentially adverse changes in biomarker concentrations. Age-related changes in immune and metabolic biomarkers, known to be associated with poor outcomes in older adults, begin as early as the thirties.

Professor in Medicine
Cohen

Harvey Jay Cohen

Professor of Medicine
Dr. Cohen's research program includes clinical research relating to aspects of the pathways to functional decline and reilience with aging, geriatric assessment, and cancer and anemia in the elderly. Pathways to functional decline are being explored through the NIA funded Claude Pepper Older Americans Independence Center, and includes studies of the contributions of age related physiologic change, in particular changes in inflammatory parameters, comorbid diseases and con
Ilkayeva

Olga Ilkayeva

Assistant Professor in Medicine
Olga Ilkayeva, Ph.D., is the Director of the Metabolomics Core Laboratory at Duke Molecular Physiology Institute. She received her Ph.D. training in Cell Regulation from UT Southwestern Medical Center at Dallas, TX. Her postdoctoral research in the laboratory of Dr. Chris Newgard at Duke University Medical Center focused on lipid metabolism and regulation of insulin secretion. As a research scientist at the Stedman Nutrition and Metabolism Center, Dr. Ilkayeva expanded her studies to include the
Kraus

Virginia Byers Kraus

Professor of Medicine
My special area of expertise is as a clinician scientist investigating osteoarthritis. Osteoarthritis is the most common form of joint disease in man and its incidence increases with age. It is a problem of increasing concern to the medical community due to the increasing longevity of the population. Trained as a molecular biologist and a Rheumatologist, I endeavor to study this disease from bedside to bench. The work in this laboratory focuses on osteoarthritis and deals w
Kraus

William Erle Kraus

Richard and Pat Johnson University Distinguished Professor
My training, expertise and research interests range from human integrative physiology and genetics to animal exercise models to cell culture models of skeletal muscle adaptation to mechanical stretch. I am trained clinically as an internist and preventive cardiologist, with particular expertise in preventive cardiology and cardiac rehabilitation.  My research training spans molecular biology and cell culture, molecular genetics, and integrative human exercise physiology and metabolism. I pr
Morey

Miriam C. Morey

Professor in Medicine
The general focus of Dr. Morey's work is exercise and aging. All of her research examines how physical activity, exercise training, or physical fitness influence the physical functioning and/or pyschosocial quality of life of older adults. She directs a supervised hospital-based program for older adults, which is used to examine longitudinally the effects of exercise training on the musculoskeletal, articular, and cardiorespiratory systems. Furthermore, she has a number of studies that e
Newby

Laura Kristin Newby

Professor of Medicine
Research Description General Focus: Clinical investigation the process and treatment of acute and chronic coronary artery disease and systems issues for delivery of care to patients with these illnesses. Particular interests include management of patients with chest pain and unstable angina, evaluation of the use of biochemical markers other than CK-MB for diagnosis and risk stratification in these patients, issues related to coronary artery disease in women, and systems issues
Parker

Daniel Christopher Parker

Assistant Professor of Medicine
Biological aging is the greatest risk factor for most chronic diseases, including frailty and dementia. The geroscience hypothesis posits that interventions that target aspects of biological aging may delay or prevent many of these diseases simultaneously. My research centers on understanding the mechanisms of interventions that affect biological aging, like exercise training and caloric restriction and using that understanding to develop therapies that maintain cognitive and physical function i
Pieper

Carl F. Pieper

Professor of Biostatistics & Bioinformatics
Analytic Interests. 1) Issues in the Design of Medical Experiments: I explore the use of reliability/generalizability models in experimental design. In addition to incorporation of reliability, I study powering longitudinal trials with multiple outcomes and substantial missing data using Mixed models. 2) Issues in the Analysis of Repeated Measures Designs & Longitudinal Data: Use of Hierarchical Linear Models (HLM) or Mixed Models in modeling trajectories of multipl
