NLRP6 modulates neutrophil homeostasis in bacterial pneumonia-derived sepsis.

ABSTRACT: Bacterial pneumonia is a significant cause of morbidity, mortality, and health care expenditures. Optimum neutrophil recruitment and their function are critical defense mechanisms against respiratory pathogens. The nucleotide-binding oligomerization domain-like receptor (NLRP) 6 controls gut microbiota and immune response to systemic and enteric infections. However, the importance of NLRP6 in neutrophil homeostasis following lung infection remains elusive. To investigate the role of NLRs in neutrophil homeostasis, we used Nlrp6 gene-deficient (Nlrp6^-/-) mice in a model of Klebsiella pneumoniae-induced pneumonia-derived sepsis. We demonstrated that NLRP6 is critical for host survival, bacterial clearance, neutrophil influx, and CXC-chemokine production. Kp-infected Nlrp6^-/-<
