Calcitonin gene-related peptide immunoreactivity in the hypothalamo-hypophysial system of the green frog, Rana esculenta.
The distribution of calcitonin gene-related peptide (CGRP) has been investigated in the hypothalamus of the frog Rana esculenta L. by means of different immunohistochemical techniques. A few immunopositive cell bodies and several fibers have been demonstrated in the preoptic area and in the caudal hypothalamus. Some CGRP-like fibers were also recognized in the outer zone of the median eminence. Simultaneous double immunofluorescence methods showed CGRP-like immunoreactivity to be often contiguous to substance P-like positive structures, but separated from them.
