Neonatal hypoglycemia is characterized by hyperinsulinemia, which contributes to not only hypoglycemia but also seizures.  In collaboration with Dr. Abdeslem El Idrissi, we have shown that neonatal hypertaurinemia contributes to seizures, but also to increased beta cell mass.  The mechanism through which seizures present is related to an alteration in the GABAergic signaling system in the brain.  My laboratory has shown that this neonatal hypertaurinemia also increases the number and size of pancreatic islets during development.  Using cell culture and animal models, we propose that neonatal hypertaurinemia may contribute to neonatal hypoglycemia through interference with the neuronal GABAergic system, increased beta cell mass through reduction of developmentally-regulated apoptosis in the pancrease, and subsequent hyperinsulinemia.
