CNS-penetrant NLRP3 inhibitor TN-783 achieves durable weight loss and reverses hypothalamic inflammation in diet-induced obesity

Increased chronic activation of this critical pathway has been implicated in obesity, with increased hypothalamic neuroinflammation linked to dysregulation of energy balance. TN-783 is an investigational CNS-penetrant small-molecule NLRP3 inhibitor that potently suppresses inflammasome activation.

In diet-induced obese (DIO) mice, TN-783 produced progressive and sustained weight loss. Transcriptomic profiling revealed partial reversal of obesity-associated molecular changes, particularly among genes involved in inflammation and neuronal signaling.
