I was fortunate to experience the excitement of discovery and put those discoveries into one piece. I would not be ready to start my career as a scientist without this experience. I want first to thank my advisor, Yuki Oka, for his patience and guidance during my Ph.D. journey. I was given full support and independence for my project. As a mentor, his passion for science is something I admired and respected. I hope to continue science like him. I would also like to thank my thesis committee for constructive discussion and advice, and especially Prof. Henry Lester, for his insight and encouragement. Getting my Ph.D. was not always being enjoyable but Henry was always available for me to listen and help. I also thank Prof. David Anderson for the discussions and comments, which were critical and improved our manuscript. Lastly, I thank Prof. Carlos Lois, who passionately participated in our meetings. His insight was critical and improved our manuscript. I also thank all the lab members for their patience and generosity for sharing in our equipment. I especially thank Vineet Augustine and Haruka Ebisu. We conducted experiments together as a team and also had constructive discussions.

  • Selectively Inhibiting the Median Preoptic Nucleus Attenuates Angiotensin II and Hyperosmotic- Induced Drinking Behavior and Vasopressin Release in Adult Male Rats
    New Research Integrative Systems Selectively Inhibiting the Median Preoptic Nucleus Attenuates Angiotensin II and Hyperosmotic- Induced Drinking Behavior and Vasopressin Release in Adult Male Rats Alexandria B. Marciante, Lei A. Wang, George E. Farmer, and J. Thomas Cunningham https://doi.org/10.1523/ENEURO.0473-18.2019 Department of Physiology and Anatomy, University of North Texas Health Science Center, Fort Worth, TX 76107 Visual Abstract The median preoptic nucleus (MnPO) is a putative integrative region that contributes to body fluid balance. Activation of the MnPO can influence thirst, but it is not clear how these responses are linked to body fluid homeostasis. We used designer receptors exclusively activated by designer drugs (DREADDs) to determine the Significance Statement The median preoptic nucleus (MnPO) is an important regulatory center that influences thirst, cardiovascular and neuroendocrine function. Activation of different MnPO neuronal populations can inhibit or stimulate water intake. However, the role of the MnPO and its pathway-specific projections during angiotensin II (ANG II) and hyperosmotic challenges still have not yet been fully elucidated. These studies directly address this by using designer receptors exclusively activated by designer drugs (DREADDs) to acutely and selectively inhibit pathway-specific MnPO neurons, and uses techniques that measure changes at the protein, neuronal, and overall physiologic and behavioral level. More importantly, we have been able to demonstrate that physiologic challenges related to extracellular (ANG II) or cellular (hypertonic saline) dehydration activate MnPO neurons that may project to different parts of the hypothalamus.

  • Amplification of Transducer Gain by Angiotensin II- Mediated Enhancement of Cortical Actin Density in Osmosensory Neurons
    9536 • The Journal of Neuroscience, September 17, 2008 • 28(38):9536–9544 Cellular/Molecular Amplification of Transducer Gain by Angiotensin II- Mediated Enhancement of Cortical Actin Density in Osmosensory Neurons Zizhen Zhang and Charles W. Bourque Centre for Research in Neuroscience, McGill University and Montreal General Hospital, Montreal, Quebec, Canada H3G 1A4 Osmosensory neurons transduce osmotic signals into a neural spike code that commands behavioral and endocrine responses that mediate body fluid homeostasis. Although changes in osmoregulatory reflex gain are known to occur under physiological and patholog- ical conditions, the basis for this modulation is unknown. Here, we show that angiotensin II amplifies osmosensory transduction by enhancing the proportional relationship between osmolality, receptor potential, and action potential firing in rat supraoptic nucleus neurons. This effect is mediated by a phospholipase C- and protein kinase C-dependent increase in cellular mechanosensitivity that is associated with a rapid increase in cortical actin filament density. Preventing this increase with cytochalasin D eliminated the enhance- ment of mechanosensitivity, whereas enhancing actin filament density with jasplakinolide potentiated mechanosensitivity and occluded theeffectsofangiotensinII.Theseresultsindicatethatareceptor-mediatedincreaseincorticalactindensitycanenhanceosmosensitivity in acutely isolated supraoptic neurons.
