Fig 9. Schematic illustration of the mechanism of CB2R activation inhibits NLRP3 inflammasome in peritoneal macrophages.

Fig 9

Once HU 308 binds to CB2R receptor in macrophages, phosphorylates the AMPK-mTOR-P70S6K signaling cascades and thus promotes peritoneal macrophages autophagy. Augment of autophagy inhibits NLRP3 inflammasome initiation and activation, which decreases Casp-1 activation and IL-1β mature and alleviates an inflammatory cascade.
