This experience provided a broad perspective on various aspects of neuroscience towards understanding complex brain disorders. As a graduate student in Dr. Marina Wolf’s laboratory, at Chicago Medical School, I began investigating the role of neuronal plasticity in drug addiction. I joined Dr. Eric Nestler’s laboratory, at Yale University, and studied the role of neurotrophic factors in adult brain with an emphasis on synaptic plasticity mechanisms. As an independent investigator, I have continued to study plasticity mechanisms underlying two areas of research, antidepressant efficacy and Rett syndrome. Our first important finding in the field of antidepressant efficacy was that the growth factor, brain- derived neurotrophic factor (BDNF), is required to mediate an antidepressant effect in preclinical animal models. We extended this finding to show that BDNF, specifically in the hippocampus, is necessary for antidepressant action through presumed effects on synaptic plasticity mechanisms. We also showed that gender differences observed in depressed humans, with females being more vulnerable, can be recapitulated in this BDNF mouse model. More recently, we have been investigating the cellular mechanisms that underlie the ability of ketamine, a compound with NMDA receptor antagonist properties, to produce rapidly acting antidepressant responses. We found that NMDA receptor blockade at rest de-suppresses protein translation and potentiates excitatory https://www.directvote.net/sfn/app/bio_page.aspx?item=4&option=4001&return=ballot_page.aspx[5/11/2017 3:10:50 PM] DirectVote Election: Candidate Bios synapses, thereby triggering rapid behavioral antidepressant responses. These and other results suggest a synaptic basis for the antidepressant effects of ketamine. We have also recently shown that the ketamine metabolite, 2R,6R-HNK, blocks synaptic NMDA receptors and recruits the same signal transduction pathway as ketamine in mediating a rapid antidepressant response. These studies indicate the importance of NMDA receptors, coupled to intracellular signaling, in ketamine- mediated rapid antidepressant effects and provide a framework for points of convergence in understanding antidepressant efficacy. Our work may contribute towards the development of more effective treatments for depression. In a second line of research, we have been studying the role of MeCP2, the gene linked to Rett Syndrome, at the behavioral as well as synaptic levels. Although loss of function mutations of MeCP2 cause Rett syndrome, the mechanisms by which such mutations lead to abnormalities in behavior, as well as the underlying functional mechanisms, have remained unknown. We have shown that mice with altered MeCP2 expression selectively in the forebrain exhibit a range of behavioral abnormalities reminiscent of symptoms seen in humans with Rett syndrome. This loss of MeCP2 function results in dramatic alterations in basal excitatory neurotransmission in hippocampus, which is mediated by presynaptic mechanisms and appears to be due to MeCP2’s role as a transcriptional repressor. MeCP2 is an epigenetic factor that is linked to changes in DNA methylation and histone deacetylase (HDAC) activity. We have extended our work to investigate the role of other epigenetic factors, specifically DNA methyltransferases and individual HDACs, in synaptic transmission and complex behavior. This work delineates how epigenetic mechanisms may regulate properties of neurotransmission in the CNS and may point to strategies for novel treatments.

ABSTRACT Background Assays measuring defense behavior in rodents, including the elevated plus maze, open field and light-dark box assays, have been widely used in preclinical models of anxiety to study the ability of therapeutic interventions to modulate the anxiety-like state. However, many important proposed anxiety-modulating factors, including genes, drugs and stressors have had paradoxical effects in these assays across different studies.

Personal Statement My research interests are focused on the basic mechanisms that underlie the formation and function of synapses in the central nervous system in health and disease. Since its inception, our laboratory has uncovered several novel facets of synaptic transmission, synapse formation as well as synapse maturation in the CNS. The key contribution of our research is the demonstration that spontaneous and evoked neurotransmission processes are segregated both in their presynaptic origins and postsynaptic targets. Our work has identified spontaneous neurotransmission as an autonomous neuronal signaling pathway independent of action potential-evoked synaptic transmission. In the last decade, we used imaging and electrophysiological approaches as well as molecular tools to pursue this novel signaling mechanism on both sides of the synapse. We developed tools to visualize trafficking of multiple synaptic vesicle proteins simultaneously within individual synapses.

All rights reserved 0893-133X/17 www.neuropsychopharmacology.org TrkB Signaling in Dorsal Raphe Nucleus is Essential for Antidepressant Efficacy and Normal Aggression Behavior Megumi Adachi1,2, Anita E Autry1,2, Melissa Mahgoub1, Kanzo Suzuki1 and Lisa M Monteggia*,1 1 Department of Neuroscience, The University of Texas Southwestern Medical Center, Dallas, TX, USA Brain-derived neurotrophic factor (BDNF) and its high affinity receptor, tropomyosin receptor kinase B (TrkB), have important roles in neural plasticity and are required for antidepressant efficacy. Studies examining the role of BDNF-TrkB signaling in depression and antidepressant efficacy have largely focused on the limbic system, leaving it unclear whether this signaling is important in other brain regions. BDNF and TrkB are both highly expressed in the dorsal raphe nucleus (DRN), a brain region that has been suggested to have a role in depression and antidepressant action, although it is unknown whether BDNF and TrkB in the dorsal raphe nucleus are involved in these processes. We combined the adeno-associated virus (AAV) with the Cre-loxP site-specific recombination system to selectively knock down either Bdnf or TrkB in the DRN. These mice were then characterized in several behavioral paradigms including measures of depression-related behavior and antidepressant efficacy. We show that knockdown of TrkB, but not Bdnf, in the DRN results in loss of antidepressant efficacy and increased aggression-related behavior. We also show that knockdown of TrkB or Bdnf in this brain region does not have an impact on weight, activity levels, anxiety, or depression-related behaviors.
