NADPH Oxidase-1 Suppression Prolongs the Antidepressant-Like Effect of Ketamine
Researchers introduced K‑4, a novel AMPA‑receptor positive allosteric modulator, which produced rapid and sustained antidepressant‑like effects in treatment‑resistant depression rat models. Bulk RNA‑seq revealed that K‑4 markedly down‑regulated NADPH oxidase‑1 (NOX‑1) in the medial prefrontal cortex and lateral habenula. Pharmacological inhibition or shRNA‑mediated knockdown of NOX‑1 prolonged ketamine’s antidepressant response and restored normal circuit activity, while NOX‑1 overexpression abolished K‑4’s durability. The work identifies NOX‑1 suppression as a mechanistic lever to extend ketamine‑type therapies.
