Cells Co-Producing Insulin and Glucagon in Congenital Hyperinsulinism.

ABSTRACT: Alterations of pancreatic islet cell phenotypes are well established in diabetic conditions and considered to be one of the possible causes of insulin deficiency. However, there is limited information about alterations of islet cell phenotypes in opposite metabolic conditions such as hypoglycemia in infants with congenital hyperinsulinism (CHI). Surgical biopsies of the pancreas from six infants with diffuse CHI and five infants with focal CHI were examined using double immunofluorescence with antibodies against insulin, glucagon and the key transcriptional factor responsible for β-cell differentiation and maturation-PDX1. The phenotypes of cells within the pancreatic islets in diffuse CHI and within the focus in focal CHI were compared to those in unaltered pancreatic islets located outsi
