Gut microbiota dysbiosis exacerbates microscopic polyangiitis via toll-like receptor 7

Key Points

This research aims to investigate the role of gut microbiota dysbiosis in aggravating microscopic polyangiitis and its mechanisms.
Utilized MPA rat models to explore the effects of microbiota dysbiosis.
Examined the release of NETs and immune responses.
Analyzed kidney damage related to TLR7 activation.
Microbiota dysbiosis resulted in increased NET release and severe microinflammation.
Disruption of immune homeostasis was observed in MPA rats.
Significant exacerbation of organ damage in the kidneys was recorded.

Abstract

Our findings show that microbiota dysbiosis led to increased release of NETs, more severe microinflammation, disruption of immune homeostasis, and exacerbated organ damage in the kidneys of MPA rats through activation of TLR7.
