Ameliorating gut microenvironment through staphylococcal nuclease-mediated intestinal NETs degradation for prevention of type 1 diabetes in NOD mice

摘要

Aims: Recent studies have revealed that neutrophil extracellular traps (NETs) provide negative feedback in the progression to chronic inflammation and contribute to the pathogenesis of multiple autoimmune diseases including type 1 diabetes (T1D). In addition, accumulating evidences suggest that gut immunity play a key role in T1D pathogenesis. Our study aimed to evaluate whether staphylococcal nuclease (SNase) targeting intestinal NETs can ameliorate the intestinal inflammatory environment and protect against T1D development in non-obese diabetic(NOD) mice.
