Male C57BL/6 mice (6–8 weeks old, 20–25 g weight) and male ICR mice (6–8 weeks old, 25–30 g weight) were purchased from the Model Animal Research Center of Nanjing University (Nanjing, China), where all animals were housed under specific pathogen–free (SPF) conditions. The IL37tg mice on a C57BL/6 background were from Cyagen Biosciences Inc. Briefly, human IL-37 cDNA (NM_014439.3) was cloned and then inserted downstream of the CMV promoter in pRP [Exp] vector (VB150824-10008) (20 (link), 24 (link)). Besides, Pdx1cre mice (International Mouse Strain Resource [IMSR] catalog JAX:014647, RRID: IMSR_JAX:014647, The Jackson Laboratory) and Gsdmdfl/fl (Model Animal Research Center of Nanjing University, Nanjing, China) were intercrossed to generate pancreatic GSDMD-specific knockout (Pdx1cre Gsdmdfl/fl, GsdmdΔPan) (8 (link)).
All animal experiments were conducted in accordance with the Principles of Laboratory Animal Care, and were approved by the Experimental Animal Ethics Committee of Jinling Hospital, affiliated with Nanjing University.
