Inappropriate inflammation responses contribute to mortality during sepsis.
Through Toll-like receptors (TLRs), reactive oxygen species (ROS) produced by
NADPH oxidase could modulate the inflammation responses. Parkinson disease
(autosomal recessive, early onset) 7 (Park7) has a cytoprotective role by
eliminating ROS. However, whether Park7 could modulate inflammation responses and
mortality in sepsis is unclear. Here, we show that, compared with wild-type mice,
Park7(-/-) mice had significantly increased mortality and bacterial burdens in
sepsis model along with markedly decreased systemic and local inflammation, and
drastically impaired macrophage phagocytosis and bacterial killing abilities.
Surprisingly, LPS and phorbol-12-myristate-13-acetate stimulation failed to
induce ROS and proinflammatory cytokine production in Park7(-/-) macrophages and
Park7-deficient RAW264.7 cells. Through its C-terminus, Park7 binds to p47(phox),
a subunit of the NADPH oxidase, to promote NADPH oxidase-dependent production of
ROS. Restoration of Park7 expression rescues ROS production and improves survival
in LPS-induced sepsis. Together, our study shows that Park7 has a protective role
against sepsis by controlling macrophage activation, NADPH oxidase activation and
inflammation responses.
