The expression level of PKM2 in pancreas tissues was detected by quantitative reverse\u2010transcription polymerase chain reaction and western blot analysis. The blood glucose levels in STZ induced T1D mouse models were measured to validate the establishment of T1D models. The pathological changes of T1D mouse were examined by hematoxylin and eosin. The oxidative stress (OS) and inflammatory response in T1D mouse were determined by measuring the expression levels of malondialdehyde, superoxide dismutase, and 8\u2010OHdG in pancreatic tissues and the serum levels of interleukin\u20106 and tumor necrosis factor\u2010\u03b1. The ability to catabolize glucose was assessed through intraperitoneal glucose tolerance test and insulin tolerance test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>\u03b2\u2010cell\u2010specific PKM2 knockout was successfully achieved in PKM2fl\/flcre+ mouse.
