Abstract

Although inflammasome plays a well-known role in animal models of renal injury, limited studies in humans are available, and its participation in diabetic kidney disease (DKD) remains unknown. Aim of this study was to elucidate the contribution of inflammasome genetics in the development of DKD in type-1 diabetes (T1D).The association of functional variants in inflammasome genes with DKD was assessed by multivariate analysis in a retrospective and in a prospective cohort.NLRP1 rs2670660 and rs11651270 polymorphisms were significantly associated with a decrease risk to develop DKD (padj<0.01), and rs11651270 also with a lower risk of new renal events during follow-up (padj=0.01). Supporting these findings, diabetes metabolites (glycated albumin and high glucose) were able to modulate NLRP1 expression.This study is the first to suggest a protective role of NLRP1 in DKD, highlighting an emerging role of NLRP1 as a homeostatic factor against metabolic stress.
