Immuno-electron-microscopic analysis of the basal route of secretion in the subcommissural organ of the rabbit.

abstract：:The intrapancreatic localization and the effects on basal and stimulated insulin secretion of neuropeptide Y (NPY) were investigated in the mouse. Immunocytochemistry showed NPY to be confined to intrapancreatic nerve fibers mainly associated with blood vessels. Fine varicose NPY fibers were also detected in the exocr...
