Tissue-type plasminogen activator in somatostatin cells of rat pancreas and hypothalamus.


Plasminogen activators (PAs) proteolytically convert plasminogen to plasmin, which, in turn, can degrade most proteins. This system has been implicated in a variety of biological processes. Using immunocytochemical methods, we here describe the localization of tissue-type PA (t-PA) in rat somatostatin cells. In the pancreatic islets, a low number of… (More)
