Lisa Monteggia is an American neuroscientist, a Professor in the Department of Pharmacology, Psychiatry & Psychology as well as the Barlow Family Director of the Vanderbilt Brain Institute at Vanderbilt University in Nashville, Tennessee. Monteggia currently probes the molecular mechanisms underlying psychiatric disorders and has made critical discoveries about the role of the neurotrophins in antidepressant efficacy, the antidepressant mechanisms of Ketamine, as well as the epigenetic regulation of synaptic transmission by MeCP2.

Early life and education[edit]

Monteggia pursued her undergraduate education at the University of Illinois at Urbana-Champaign.[1] In 1989, Monteggia completed her bachelors of science in microbiology and then went on to complete a masters of science in biology at the University of Illinois as well.[1] After completing her masters in 1991, Monteggia moved from academia to industry to work for the pharmaceutical company, Abbott Laboratories, in Abbott Park, Illinois.[2] At Abbot Laboratories, Monteggia first held the position of Associate Scientist from 1991 to 1994, and was then promoted to Scientist in 1994.[3]

Around the same time that Monteggia was promoted to Scientist, she began her Ph.D. at Chicago Medical School at Rosalind Franklin University.[1] Monteggia worked under the mentorship of Dr. Marina Wolf probing the neurobiology of drug abuse in rodents, specifically the role of glutamate in neuroadaptations.[3] During her PhD, Monteggia found that the expression of the glutamate receptor NMDAR1 drastically decreases in the ventral midbrain, nucleus accumbens, and prefrontal cortex two weeks after the onset of drug abstinence.[4] For her dissertation, titled “Glutamate Receptors and Amphetamine Sensitization”, Monteggia found, contrary to other studies, 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.[5] 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.[5]

After completing her PhD in 1999, Monteggia pursued her postdoctoral training at Yale University under the mentorship of Dr. Eric Nestler in the Department of Psychiatry.[3] During her postdoctoral studies, Monteggia published a first author paper cloning and characterizing the expression of various neuronal pacemaker channels called hyperpolarization-activated, cyclic nucleotide-gated channels 1-4 (HCN1-4).[6] The distinct expression patterns of these channels across regions might highlight the unique ways in which neuronal pacemaker cells affect different brain systems.[6]

Career and research[edit]

Following her postdoctoral training, Monteggia was recruited to UT Southwestern in Dallas, Texas to hold the title of Research Assistant Professor in the Department of Psychiatry.[2] She held this position from 2000 until 2002, at which point she was promoted to assistant professor of the Department of Psychiatry.[2] As an assistant professor, Monteggia built her research program around exploring the effects of neurotrophins on antidepressant behaviors as well as the role of Methyl-CpG-binding protein 2 (MeCP2) on synaptic plasticity.[2] The MeCP2 gene is known to be linked to Rett Syndrome. In 2014, Monteggia and her lab used a novel inducible knockout system to selectively knock out Brain-derived Neurotrophic Factor, a neurotrophin, in the forebrains of mice to explore the role of BDNF in complex behaviors.[7] They found that depletion of BDNF impaired hippocampal learning and long-term potentiation and they further found that a loss of BDNF also impaired the effects of the antidepressant, desipramine.[7] Monteggia’s group then showed that selective loss of BDNF in the dentate gyrus region of the hippocampus, but not the CA1 region, attenuates the effects of the antidepressants desipramine and citalopram during the forced swim test.[8] Her findings suggest that the actions of antidepressants on specifically the dentate gyrus region of the hippocampus mediate their therapeutic effects.[8]

In her other major research area studying MeCP2, Monteggia found in 2006 that MeCP2 acts as a transcriptional silencer to control synaptic transmission at excitatory presynaptic membranes.[9] 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.[10] These findings highlight the role, at a mechanistic level, 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.[10]

In 2009, Monteggia was promoted to tenure-track associate professor and in 2010 she was honored with the Ginny and John Eulich Professorship in Autism Spectrum Disorders.[2] As of 2013, Monteggia was promoted to full professor and remained at UT Southwestern until 2018.[1] During this time at UT Southwestern, Monteggia continued to probe the functions of MeCP2 in the central nervous system (CNS) as well as further explore the mechanisms of actions of BDNF in mediating the effects of antidepressants. Monteggia continued to report on the efficacy and validity of the use of transgenic mouse models in the study of neuropsychiatric disorders, such as MeCP2 knockout mice for studying Rett Syndrome.[11] Also during this time, Monteggia started to explore the rapid antidepressant effects of ketamine and why memantine does not have these same effects.[12] 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.[12] Monteggia, and her collaborator, Dr. Ege Kavalali, also discovered that ketamine modulates homeostatic plasticity in the hippocampus, which strongly correlates with the antidepressant effects and has been proposed to mediate the behavioral effects. Moreover, Monteggia and Kavalali have put forth the novel hypothesis that homeostatic synaptic plasticity may be a target for the treatment of mood disorders based on their work with ketamine and lithium.[13] During Monteggia’s time at UT Southwestern, she was the thesis mentor for 10 graduate students and served on many thesis committees.[1]

By 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.[14] She is also a Vanderbilt Kennedy Center Investigator based on her work elucidating the role of MeCP2 in the neurodevelopmental disorder Rett Syndrome.[15] At Vanderbilt, 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.[14]

Monteggia is currently an Associate Editor of Neuropsychopharmacology, a member of the editorial boards of the Journal of Neuroscience, Journal of Biological Chemistry and Biological Psychiatry, as well as a reviewing editor for eLife.[2] Monteggia is also a Board Member of the Rett Syndrome Foundation, on the Scientific Council for the Brain & Behavior Research Foundation, a m member of the Dana Alliance for Brain Initiatives, a Councilor for the Molecular and Cellular Cognition Society (MCCS), an elected Councilor of the Society for Neuroscience and she also serves on the Advisory Committee to the NIH Director for BRAIN Initiative Working Group 2.0.
