HCAR1 and Hypoglycemia: Further, as newborn hypoglycemia is a relatively common perinatal complication thought to have possible long-term consequences on brain maturation (De Angelis et al., 2021) and since lactate is associated with both development (Bauernfeind et al., 2014) and hypoglycemic protection (van Gemert et al., 2022), we wanted to investigate the influence of HCAR1 on axonal and myelin development in a model of perinatal hypoglycemia.
