Research
Research in the Zeltser laboratory explores how developmental influences exert lasting impacts on body weight regulation. Epidemiological studies provide strong evidence that interactions between genetic and early environmental factors influence later susceptibility to obesity and eating disorders. A major obstacle to elucidating the underlying mechanism for these effects is that most research programs are focused on the neuroanatomy and physiology of body weight regulation in adults. We are using a two-pronged approach to identify critical developmental processes in the central and peripheral nervous system that regulate susceptibility to childhood obesity and anorexia nervosa. First, we use a combination of genetic, environmental and/or dietary manipulations in mice to define the timing and types of exposures needed to recapitulate basic epidemiological observations in humans. Then we use genetic and pharmacological tools to characterize the consequences of these developmental factors on the maturation of neuronal circuits that, in turn, mediate effects on metabolic, neuroendocrine and behavioral phenotypes. By applying the rigor and precision of developmental neuroscience to mouse models of susceptibility to body weight dysregulation, our research is yielding new insights into the causes of childhood obesity and anorexia nervosa, and could lead to new therapeutic strategies to treat these disorders.
