title: A signal for the caspase-1 inflammasome free of TLR.
abstract: Secretion of the proinflammatory cytokine IL-1beta requires caspase-1 and Toll-like receptor (TLR) signaling. However, Kanneganti et al. (2007) find that bacteria can use pore-forming mechanisms to activate caspase-1 for the production of IL-1beta precursor independently of TLRs.
