Core Tip

Core Tip: One of the main challenges in the advancement of antidepressant therapy is the establishment of safe and effective fast-acting antidepressants. Ketamine is a prototype for rapid-onset antidepressant responses. Agmatine has been shown to produce fast antidepressant-like effect by stimulating mechanistic target of rapamycin complex 1 signaling pathway, similar to ketamine. Moreover, NLR family pyrin domain containing 3 and microbiota-gut-brain axis may be novel targets for fast antidepressant responses. These targets have also been postulated to play a role in the antidepressant effect of both ketamine and agmatine.
