Research Interests

Dr. de Kloet’s research program is broadly focused on elucidating mechanisms underlying obesity and co-morbid conditions such as hypertension and diabetes.  A particular emphasis is placed on the interactions among the neural circuits that regulate energy balance with those that control blood pressure, and also on the impact that the renin-angiotensin system has on these circuits.   Some specific research topics currently being explored include: the impact of high-fat diet on angiotensin-sensitive neural circuits; the role of angiotensin-II and related peptides in the neuroendocrine regulation of energy balance; optogenetic targetting of angiotensin-sensitive neurons of the nodose ganglion to combat obesity and hypertension; mechanisms by which angiotensin-senstive neurons of the median preoptic nucleus coordinate physiological and pathophysiological responses to hypertensive stimuli; mechanisms linking angiotensin-sensitive neurons and thermogenic responses to pertubations in energy balance and blood pressure regulation.

In order to explore these and other research topics, the de Kloet lab uses a mutli-level approach that has spans the use of several molecular, genetic, physiological and behavioral techniques.  Some examples of the approaches used in her laboratory are: telemetry and indirect calorimetery, which are used to assess cardiovascular parameters and energy expenditure respectively; optogenetics, fiber photometry, neuronal tract tracing, mRNA in situ hybridization, and immunohistochemistry, which are used to characterize the structure and function of specific sets of neurons involved in these processes; and genetic recombination and virally-mediated gene transfer techniques, which allow for the manipulation of gene expression in specific cellular phenotypes.
