NLRP3 inhibition by VTX3232 tempers inflammation resulting in reduced body weight, hyperglycemia, and hepatic steatosis in obese male mice.

ABSTRACT: The NLRP3 inflammasome is a key innate immune sensor that orchestrates inflammatory responses to diverse stress signals, including metabolic danger cues. Dysregulated NLRP3 activation has been implicated in chronic diseases such as type 2 diabetes, atherosclerosis, and neurodegeneration, underscoring the broad pathophysiological role of the NLRP3 pathway. In the context of obesity and its associated conditions, NLRP3 inhibition by VTX3232, an oral, selective, and brain-penetrant NLRP3 inhibitor, potently suppressed the release of proinflammatory cytokines (IL-1β, IL-18, IL-1α, IL-6, and TNF) from macrophages and microglia stimulated with metabolic stressors including palmitic acid and cholesterol crystals. Moreover, NLRP3 inhibition by VTX3232 also blocked NLRP3-driven insulin resistance i
