Joanna Dabrowska, PhD, PharmD
Dr. Joanna Dabrowska earned a PharmD in 2000 from Wroclaw Medical University and a PhD in Neuropharmacology in 2006 from the Medical University of Silesia. She continued her postdoctoral training at Emory University and in 2012 she was awarded a ‘Pathway to Independence’ K99/R00 grant from NIMH. In 2014, she joined the faculty of the Chicago Medical School as an assistant professor of cellular and molecular pharmacology and neuroscience.
The Dabrowska Lab is currently supported by the Rosalind Franklin University of Medicine and Science and an R01 grant from the National Institute of Mental Health (R01 MH113007).
The goal of research in the Dabrowska Lab is to understand how repeated stress exposure can lead to neuroplasticity of selective neuronal circuits and long-term changes in stress-coping behavior, which ultimately leads to the development of psychiatric disorders like depression, anxiety, and/or addiction. Since chronic stress is a potential risk factor for the development of these diseases we seek to understand how stress interacts with affect at the molecular, cellular, physiological, and behavioral level, and what are their respective roles in the etiology of the mental disorders. To understand the complex endpoint of psychiatric disorders, we study innate stress-coping mechanisms using animal models of stress, depression, anxiety, and addiction to examine how disruption of these mechanisms could lead to the development of disease.
Development of depression and anxiety has long been associated with stressful life events and, consequently, hyperactivation of the major stress hormone - corticotropin releasing factor (CRF) system. Specifically, activation of the CRF system in the extended amygdala has been linked to the negative affect of the stress response. For example, the CRF neurons in the bed nucleus of the stria terminalis (BNST) have been shown to undergo highly plastic molecular and physiological changes in response to chronic stress, which ultimately leads to increased anxiety-like behavior (Dabrowska et al., 2013).
The major research project in the lab focuses on the intricate relationship between CRF and another neuropeptide, oxytocin, between two brain regions critically involved in the regulation of stress response and affective behavior, namely the hypothalamus and the BNST. Based on the neuroanatomical circuit described in Dabrowska et al., 2011, we are using an integrative approach to investigate the anatomy and function of the circuit between CRF neurons of the BNST and oxytocin neurons in the hypothalamus. We believe these studies will lead to a better understanding of neuroendocrine regulation in neuropsychiatric disorders.
We use a variety of research techniques to investigate the circuit at the molecular (protein assays, PCR), cellular (neuronal tract tracing, immunofluorescence and confocal microscopy), neurochemical (microdialysis in freely-moving rats), physiological (in vitro patch-clamp electrophysiology), as well as behavioral level (animal models of depression and anxiety combined with adenoviral manipulations: DREADDs, optogenetics).
