NFE2L2 and Cognitive impairment: In a rodent model of streptozotocin (STZ)-induced type 1 diabetes (STZ-T1D), we previously demonstrated that recurrent hypoglycaemia (RH) further exacerbates this process through a mechanism involving increased oxidative and inflammatory stress that overwhelms the compensatory activation of the nuclear factor erythroid 2-related factor 2 (Nrf2) antioxidant system, which was insufficient to prevent cognitive impairment.
