UNC Nutrition Research Institute Seminar Series
Anorexia nervosa and the intestinal microbiota: do gut microbes influence weight gain and behavior during clinical re-nourishment? Date and Time: Thursday, April 12, 2018 12:00 PM – 1:00 PM Eastern Speaker: Ian Carroll, PhD (Assistant Professor, Department of Nutrition, University of North Carolina at Chapel Hill) Abstract: Abstract: Anorexia nervosa (AN), a psychiatric disorder characterized by extreme weight dysregulation commonly presents with comorbid anxiety. AN carries the highest mortality rate of all psychiatric illnesses and relapse is frequent. Therapeutic re-nourishment in AN is based primarily on clinical opinion and guidelines, and does not address the underlying etiology of the disorder. … Read More »

Summary: The carbohydrate-insulin model of obesity postulates that increased insulin secretion in response to a high glycemic load diet drives excess weight gain. Because of the close interrelationship between obesity, insulin resistance, and hyperinsulinism, however, investigating this hypothesis is often complicated by possibilities of confounding and reverse causation. Dr. Jose Florez and colleagues avoided these issues by using a bidirectional Mendelian randomization study to test the carbohydrate-insulin model of obesity. They assessed (1) whether a set of genetic variants associated with increased glucose-stimulated insulin secretion predict obesity and (2) whether a separate set of genetic variants associated with obesity predict … Read More »

Summary: In humans, Salmonella enterica serovar Typhimurium (S. Typhimurium) is an important cause of acute gastroenteritis. A critical step in host defense is the generation of reactive oxygen species (ROS) generated from NADPH oxidase. NADPH oxidase has multiple subunits, and mutations in various subunits may contributed to increased susceptibility to infection. Dr. Hai Ning Shi and colleagues, with the assistance of the Genomics and Cell Biology Core, elucidated the importance of the p40phox subunit of NADPH oxidase, demonstrating that mice lacking p40phox are more susceptible to infection with S. Typhimurium, as evidenced by bacterial dissemination to the liver and spleen … Read More »

Summary Chronic inflammation is thought to contribute to obesity-related insulin resistance. In obesity, adipocytes are an important source of inflammatory cytokines, but the mechanisms of adipose inflammation in obesity remain unclear. To determine transcriptional regulators of adipose inflammation, Cowan and colleagues compared transcriptional profiles of primary human adipocytes from obese donors with those from in vitro-derived adipocytes that were genetically identical to the primary adipocytes. Interferon regulatory factor 1 (IRF1) was identified as a mediator of adipocyte inflammation, as it was upregulated in primary adipocytes compared to genetically identical in vitro-derived adipocytes. Further investigation demonstrated that IRF1 overexpression in adipocytes … Read More »

Summary Childhood undernutrition and growth impairment remain substantial burdens in Sub-Saharan Africa. Environmental enteric dysfunction (EED), a subclinical condition associated with inflammation and malabsorpition in the small intestine, is associated with growth failure. As several studies have demonstrated that individuals with low weight in early childhood are at risk for cardiometabolic disease later in life, NORCH Associate Director Dr. Christopher P. Duggan, NORCH member Dr. Wafaie Fawzi, and others recently investigated whether EED in infancy is associated with cardiovascular risk measures in mid-childhood. Anti-flagellin IgA is a marker for EED and is significantly higher in Tanzanian infants compared to infants … Read More »
