Sestrin modulator NV-5138 produces rapid antidepressant effects via direct mTORC1 activation

Abstract

Preclinical studies demonstrate that rapid-acting antidepressants, including ketamine, require stimulation of mTORC1 signaling. This pathway is regulated by neuronal activity and endocrine and metabolic signals, notably including the amino acid leucine, which activates mTORC1 signaling via binding to the upstream regulator sestrin. Here, we examined the antidepressant actions of NV-5138, a highly selective small molecule modulator of sestrin that penetrates the blood-brain barrier. The results demonstrate that a single dose of NV-5138 produced rapid and long-lasting antidepressant effects and rapidly reversed anhedonia caused by chronic stress exposure. The antidepressant actions of NV-5138 required brain-derived neurotrophic factor (BDNF) release, as the behavioral responses were blocked by infusion of a BDNF-neutralizing Ab into the medial prefrontal cortex (mPFC) or, in mice, with a knockin of a BDNF polymorphism that blocked activity-dependent BDNF release. NV-5138 administration also rapidly increased synapse number and function in the mPFC and reversed the synaptic deficits caused by chronic stress. Together, the results demonstrate that NV-5138 produces rapid synaptic and antidepressant behavioral responses via activation of the mTORC1 pathway and BDNF signaling, indicating that pharmacological modulation of sestrin may be an attractive approach for the development of rapid-acting antidepressants.

Problems with a PDF?

This file is in Adobe Acrobat (PDF) format. If you have not installed and configured the Adobe Acrobat Reader on your system.

Having trouble reading a PDF?

PDFs are designed to be printed out and read, but if you prefer to read them online, you may find it easier if you increase the view size to 125%.

Having trouble saving a PDF?

Many versions of the free Acrobat Reader do not allow Save. You must instead save the PDF from the JCI Online page you downloaded it from. PC users: Right-click on the Download link and choose the option that says something like "Save Link As...". Mac users should hold the mouse button down on the link to get these same options.

Having trouble printing a PDF?

  1. Try printing one page at a time or to a newer printer.
  2. Try saving the file to disk before printing rather than opening it "on the fly." This requires that you configure your browser to "Save" rather than "Launch Application" for the file type "application/pdf", and can usually be done in the "Helper Applications" options.
  3. Make sure you are using the latest version of Adobe's Acrobat Reader.
