"Because activation of caspase-1 induced by LPS or lipopeptide and SLO requires TLR signaling, the results suggest that MyD88 and Trif independent activation of the Nlrp3 inflammasome in response to S. pyogenes infection can not be explained by SLO mediated internalization of TLR ligands."

"Although not required, additional stimulation of bacterial RNA transfected cells with the classical second signals ATP or pore forming bacterial toxins nigericin and SLO enhanced and accelerated caspase-1 activation and release of IL-1beta (XREF_FIG; note decrease in pro-IL-1beta levels due to cleavage)."
