Overview: 

Elinor Sullivan’s teaching focus is in the areas of nutrition, endocrinology, and neurobiology.

Dr. Sullivan’s research focuses on examining the influence of maternal metabolic state and dietary environment on offspring behavioral regulation, with an emphasis on behaviors that relate to mental health and behavioral disorders including autism spectrum disorders, attention deficit hyperactivity disorder, anxiety, and depression.

Her areas of expertise include behavioral neuroscience, with training and expertise in human and nonhuman primate behavior, brain development, developmental programming, maternal nutrition, and neurodevelopmental disorders.

Dr. Sullivan received her Ph.D. in Physiology from Oregon Health and Science University. She received her postdoctoral training at the University of California San Francisco and Oregon Health and Science University. Prior to coming to the University of Oregon, Dr. Sullivan was an Assistant Professor in the Biology Department at the University of Portland. Dr. Sullivan is currently an Assistant Professor in the Divisions of Neuroscience and Cardiometabolic health at the Oregon National Primate Research Center. She joined the UO Department of Human Physiology in 2017.

Dr. Sullivan has received research grants from the National Institute of Health, the Bill and Melinda Gates Foundation, the Murdock Charitable Trust, and the Obesity Society.

Abstract
Early life predictors of attention-deficit/hyperactivity disorder (ADHD) are critically needed; they could inform etiological theory and may help identify new prevention targets. The current study examined prospectively whether maternal cytokine levels during pregnancy predict offspring ADHD symptoms at age 4-6 years. Secondarily, we evaluated maternal cytokine levels as a possible common pathway through which prenatal risks exert influence on child ADHD. Data came from a sample of women recruited during the 2nd trimester of pregnancy (N=62) and followed postnatally until children were 4-6 years old. Maternal inflammation was assessed using 3rd trimester plasma concentrations of three indicators of nuclear factor kappa B signaling: interleukin-6, tumor necrosis factor-alpha, and monocyte chemoattractant protein-1 which were combined into a latent variable. Mothers and teachers reported on child ADHD symptoms, negative affect, and externalizing behaviors at 48-72 months of age. Maternal inflammation in the 3rd trimester predicted ADHD symptoms when children were 4-6 years old (β=0.53, 95% CI=0.154, 0.905, p=0.006). Further, maternal inflammation mediated the effect of prenatal distress on child ADHD (β=0.21, 95% CI=0.007, 0.419, p=0.04). The inflammation effect on ADHD was not explained by concurrent child negative affect, externalizing behavior, or familial ADHD status. This is the first human study to prospectively link maternal pregnancy cytokine levels and offspring ADHD symptoms, suggesting that cytokine levels are a possible marker of ADHD risk. Results also provides new evidence that maternal prenatal inflammation may be one common pathway by which prenatal risk factors influence offspring mental health outcomes.

Effects of pre- and postnatal protein restriction on maternal and offspring metabolism in the nonhuman primate.

Abstract
Women in low- and middle-income countries frequently consume a protein-deficient diet during pregnancy and breastfeeding. The effects of gestational malnutrition on fetal and early postnatal development can have lasting adverse effects on offspring metabolism. Expanding on previous studies in rodent models, we utilized a nonhuman primate model of gestational and early-life protein restriction (PR) to evaluate effects on the organ development and glucose metabolism of juvenile offspring. Offspring were born to dams that had consumed a control diet containing 26% protein or a PR diet containing 13% protein. Offspring were maintained on the PR diet and studied [body and serum measurements, intravenous glucose tolerance tests (ivGTTs), and dual-energy X-ray absorptiometry scans] up to 7 mo of age, at which time tissues were collected for analysis. PR offspring had age-appropriate body weight and were euglycemic but exhibited elevated fasting insulin and reduced initial, but increased total, insulin secretion during an ivGTT at 6 mo of age. No changes were detected in pancreatic islets of PR juveniles; however, PR did induce changes, including reduced kidney size, and changes in liver, adipose tissue, and muscle gene expression in other peripheral organs. Serum osteocalcin was elevated and bone mineral content and density were reduced in PR juveniles, indicating a significant impact of PR on early postnatal bone development.
