[Demonstration of VIP receptors in B cells of the pancreas by quantitative ultrastructural autoradiography].
Using quantitative electron microscopic autoradiography we demonstrated the existence of specific VIP receptors in B cells of the pancreatic islets. The presence of those receptors strongly suggests that the neuromediator can induce insulin release by direct stimulation of B cells.
