Résumé

Depression is a major public health concern in modern society, yet little is known about the molecular link between this condition and neuroinflammation. The inflammasome complex was recently shown to be implicated in depression. The present study shows the implication of NLRP3 inflammasome in animal model of stress-induced depression. Accordingly, we show here that in the absence of a NLRP3 inflammasome, prolonged stress does not provoke depressive behaviors or microglial activation in mice or dampen hippocampal neurogenesis. Indeed, NLRP3 deletion or inhibition of microglial activation impairs the stress-induced alterations associated with depression. According to these findings in animal model, the inflammasome could be a target for new therapeutic interventions to prevent depression in patients.
