  • Ketamine produces rapid antidepressant effects in treatment-resistant depression (TRD), but its benefits are short-lived.
  • A novel AMPAR positive allosteric modulator, K-4, showed more sustained antidepressant-like effects than ketamine in Wistar Kyoto rats.
  • RNA sequencing revealed lower NADPH-oxidase-1 (NOX-1) expression in the medial prefrontal cortex (mPFC) of K-4-treated rats compared to ketamine-treated rats.
  • NOX-1 inhibition prolonged ketamine's antidepressant-like effects and reduced burst firing in the lateral habenula (LHb).
  • NOX-1 knockdown in the mPFC sustained ketamine's effects and suppressed LHb bursting activity, suggesting NOX-1 as a target for TRD maintenance strategies.
