Neisseria meningitidis-Induced Caspase-1 Activation in Human Innate Immune Cells Is LOS-Dependent

Involvement of MyD88 signalling in N. meningitidis priming of NLRP3 inflammasomes. THP1 wild-type control cells and MyD88-deficient THP1 cells were subjected to the parental wild-type N. meningitidis FAM20 or its LOS-deficient mutant strain IpxA (MOI of 10) for 2 h, after mRNA expression of NLRP3 (a), IL1B (b), and CASP1 (c) was measured using RT-qPCR. Relative gene expression was calculated with the 2-∆∆CT method, using GAPDH as the reference gene and the unstimulated cells as the calibrator. Bars represent ; .
