Lisa Monteggia

Monteggia pursued her undergraduate education at the University of Illinois at Urbana-Champaign. In 1989, she completed a bachelors of science in microbiology and then went on to complete a masters of science in biology at the University of Illinois as well. where she held the position of Associate Scientist from 1991 to 1994, and was then promoted to scientist in 1994. Monteggia began her PhD at Chicago Medical School at Rosalind Franklin University For her dissertation, titled “Glutamate Receptors and Amphetamine Sensitization”, Monteggia found that after 14 days of withdrawal following chronic administration of amphetamine, glutamate receptor expression in the ventral tegmental area (VTA) did not change but while glutamate receptor expression in the substantia nigra was decreased. These findings indicate that increased excitatory drive of VTA dopamine neurons following chronic amphetamine administration must result from alternative mechanisms than modulation of glutamate receptor expression. The distinct expression patterns of these channels across regions might highlight the unique ways in which neuronal pacemaker cells affect different brain systems. == Career and research ==

Monteggia was recruited to UT Southwestern in Dallas, Texas as research assistant professor in the Department of Psychiatry. They found that depletion of BDNF impaired hippocampal learning and long-term potentiation and that a loss of BDNF also impaired the effects of the antidepressant, desipramine. Their findings suggest that the actions of antidepressants on specifically the dentate gyrus region of the hippocampus mediate their therapeutic effects. A critical follow up to this study was done by Monteggia and her lab in 2009. Since MeCP2 is thought to effect its transcriptional silencing alongside histone deacetylases (HDACs), they chronically inhibited HDACs in the basolateral amygdala and found similar behavioral effects as when they knockout MeCP2. These findings highlight the role of MeCP2 in transcriptional silencing and further that its loss of function in the BLA might be responsible for the behaviors associated with Rett Syndrome. Monteggia also started to explore the rapid antidepressant effects of ketamine and why memantine does not have these same effects. In addition to validating clinical findings of these drugs in animal models, she showed that their effects on NMDAR-mediated neurotransmission and intracellular signalling pathways differ. In 2018, Monteggia was recruited to Vanderbilt University in Nashville, Tennessee to become the Barlow Family Director of the Vanderbilt Brain Institute as well as professor of pharmacology, psychiatry & psychology. She is also a Vanderbilt Kennedy Center Investigator based on her work elucidating the role of MeCP2 in the neurodevelopmental disorder Rett Syndrome. Monteggia's Lab continues to study neurotrophins and their effects on antidepressant efficacy, the rapid antidepressant actions of ketamine, as well as the epigenetic regulation of synapse function which includes further investigations of the transcriptional depressor MeCP2 and its role in Rett Syndrome manifestation. Monteggia is an associate editor of Neuropsychopharmacology, a member of the editorial boards of the Journal of Neuroscience, Journal of Biological Chemistry and Biological Psychiatry, and a reviewing editor for eLife. == Awards ==
