Group B streptococcus (GBS), a major cause of sepsis, induces inflammatory cytokines in strict dependence of bacterial ssRNA and the host molecules MyD88 und UNC-93B. Here, we show that nitric oxide plays an important role in GBS-induced transcriptional activation of cytokine genes. Phagocytosis induced NO in a MyD88-dependent fashion. In turn, NO propagated the acidification of phagosomes and the processing of phagosomal bacterial nucleic acids and was required for potent transcriptional activation of cytokine genes by streptococci. This NO-dependent amplification loop has important mechanistic implications for the anti-streptococcal macrophage response and sepsis pathogenesis.
