Abstract:
A small amount of CGRP-ir nerve fibers were found immunohistochemically with an antiserum directed against rat CGRP in all parts of the pars distalis of adenohypophysis in the rat. They occurred in small patches or as scattered fibers. More fibers were seen in the median and dorsal parts of the gland than in lateral and ventral parts. Bundle of CGRP-ir never fibers were often observed within the pia mater covering the pituitary for some distance before entering the parenchyma. A few CGRP-ir cells were observed in the center of the caudal part of the adenohypophysis. None of them were found to be related to the CGRP-ir fibers. The large number of varicosities present along nerve fibers suggests that they may play a role in the regulation of the functions of the adenohypophysis.
