## Career and training
In March 2018, according to Vanderbilt Health News, she was named Barlow Family Director of the Vanderbilt Brain Institute and joined Vanderbilt that summer as Professor of Pharmacology.[8](https://news.vumc.org/2018/03/12/lisa-monteggia-to-lead-vanderbilt-brain-institute/) • [1](https://medschool.vanderbilt.edu/pharmacology/person/lisa-monteggia-ph-d/) At the time of the announcement, she had served as thesis mentor for ten graduate students in the UT Southwestern Neuroscience Graduate Program.[8](https://news.vumc.org/2018/03/12/lisa-monteggia-to-lead-vanderbilt-brain-institute/)
## BDNF signaling and synaptic plasticity in psychiatric disorders
Her laboratory's central thread is brain-derived neurotrophic factor (BDNF) and its receptor TrkB in adult brain function, studied with conditional and inducible cell-type-specific knockout mice, and the role of MeCP2 in synaptic function using mouse models of [Rett syndrome](https://www.edgepedia.org/rett-syndrome).[1](https://medschool.vanderbilt.edu/pharmacology/person/lisa-monteggia-ph-d/) BDNF is required for antidepressant responses: her lab showed that BDNF selectively in the hippocampal dentate gyrus is necessary to mediate antidepressant responses in rodent models.[9](https://lab.vanderbilt.edu/monteggialab/research/antidepressant/) Her earlier reviews include ["A Neurotrophic Model for Stress-Related Mood Disorders"](https://doi.org/10.1016/j.biopsych.2006.02.013) in *Biological Psychiatry* (2006).[10](https://doi.org/10.1016/j.biopsych.2006.02.013) A recent synthesis is the review ["BDNF signaling in context: From synaptic regulation to psychiatric disorders"](https://doi.org/10.1016/j.cell.2021.12.003), published in *Cell* on January 6, 2022 (Volume 185, pages 62–76), which connects BDNF's synaptic regulation to psychiatric disease.[5](https://doi.org/10.1016/j.cell.2021.12.003)
## Ketamine and rapid-acting antidepressants
Ketamine relieves major depressive symptoms within two hours of a single low-dose intravenous infusion, with effects lasting up to two weeks; her 2011 *Nature* paper asked why.[4](https://www.nature.com/articles/nature10130) The answer it offered: ketamine's blockade of NMDA receptors at rest deactivates eukaryotic elongation factor 2 (eEF2) kinase, reducing eEF2 phosphorylation and de-suppressing BDNF translation, and the rapid behavioral antidepressant effects depend on this rapid BDNF synthesis.[4](https://www.nature.com/articles/nature10130) • [9](https://lab.vanderbilt.edu/monteggialab/research/antidepressant/) The NIH grant abstract records the complementary result that inhibitors of eEF2 kinase trigger a rapid antidepressant-like effect in mice, while ketamine does not in eEF2 kinase null mice.[7](https://grantome.com/grant/NIH/R01-MH070727-14) This hypothesis also explains why memantine, a clinically used [NMDA receptor antagonist](https://www.edgepedia.org/nmda-receptor-antagonist), is not effective as a rapid antidepressant.[9](https://lab.vanderbilt.edu/monteggialab/research/antidepressant/)
In 2017 she co-authored "Effects of a ketamine metabolite on synaptic NMDAR function" in *Nature* (volume 546, pages E1–E3), examining whether a ketamine metabolite acts on synaptic NMDA receptors; Vanderbilt's announcement of the work described it as identifying proteins targeted by ketamine and opening possibilities for drugs that mimic ketamine's antidepressant benefits without its side effects.[11](https://doi.org/10.1016/j.celrep.2021.109513) • [8](https://news.vumc.org/2018/03/12/lisa-monteggia-to-lead-vanderbilt-brain-institute/) Her 2021 *Cell Reports* work then located the effect anatomically: deleting BDNF or TrkB in presynaptic CA3 or postsynaptic CA1 of the hippocampal Schaffer collateral pathway blocks ketamine-induced synaptic potentiation, showing that BDNF-TrkB signaling in CA1 neurons is the synaptic locus of ketamine's rapid action.[12](http://www.cell.com/article/S2211124721009438/pdf)
## Representative work
A representative recent paper is the review ["BDNF signaling in context: From synaptic regulation to psychiatric disorders"](https://doi.org/10.1016/j.cell.2021.12.003), published in *Cell* in 2022, which synthesizes how BDNF's regulation of synapses connects to psychiatric disorders.[5](https://doi.org/10.1016/j.cell.2021.12.003)
## Recent developments
Her lab has kept publishing on both fronts. In 2024 she co-authored two reviews, "Ketamine: Mechanisms and Relevance to Treatment of Depression" in the *Annual Review of Medicine* (75:129–143) and "Ketamine and rapid antidepressant action: new treatments and novel synaptic signaling mechanisms" in *Neuropsychopharmacology* (49(1):41–50), alongside a 2023 *Trends in Molecular Medicine* review on bridging ketamine's rapid and sustained effects.[13](https://lab.vanderbilt.edu/monteggialab/publications/) A 2024 *PNAS* paper showed BDNF scales presynaptic calcium transients to modulate excitatory neurotransmission.[13](https://lab.vanderbilt.edu/monteggialab/publications/) • [14](https://doi.org/10.1073/pnas.2303664121) According to her lab's list of publications, in May 2025 her lab reported in *Science* (388:646–655) that a single dose of ketamine's antidepressant effects can be extended from up to a week to up to two months by BCI, a drug that inhibits a protein phosphatase, increasing ERK activity and augmenting the synaptic plasticity behind ketamine's prolonged effects.[13](https://lab.vanderbilt.edu/monteggialab/publications/) • [6](https://medschool.vanderbilt.edu/basic-sciences/new-ketamine-study-promises-extended-relief-depression/) According to a 2025 *PNAS* paper, enhancing endogenous metabotropic glutamate receptor 5 (mGluR5) signaling produces hippocampal synaptic potentiation and triggers a rapid antidepressant effect similar to ketamine's, while blocking mGluR5 prevents rapid antidepressant responses.[15](https://doi.org/10.1073/pnas.2510642122) Her mechanistic view has broadened rather than reversed: the eEF2 kinase/BDNF translation account remains the lab's stated framework, now joined by mGluR5 as a parallel route to the same homeostatic synaptic plasticity.[9](https://lab.vanderbilt.edu/monteggialab/research/antidepressant/) • [15](https://doi.org/10.1073/pnas.2510642122)
