Here, the authors present the upstream pathway that controls the activation of the NLRP3 inflammasome during bacteraemia. The CNF1 toxin from Escherichia coli activates the Rho GTPase Rac2 and its activity is sensed by NLRP3, which is activated by a signalling cascade involving p21-activated kinases 1 and 2.
