NPY exhibits a broad distribution throughout the body. NPY has been localized in neurons that synthesize norepinephrine or epinephrine and also in many cell bodies which are not catecholaminergic. Coexistence of NPY and several other peptides has also been observed. Accordingly, NPY displays a wide variety of functional activities depending on its location(More)
It has recently been demonstrated that aPY, a peptide which has significant homology with neuropeptide Y (NPY) is present in extracts of anglerfish islets. The purpose of this study was to determine whether cells or nerves which contain NPY-like immunoreactivity could be identified in anglerfish islet tissue and whether aPY is synthesized by this tissue.(More)
Several types of short axon cells of the mammalian olfactory bulb have been described after Golgi impregnation. Two of these types have been observed in our material after treatment with the NADPH-diaphorase procedure or after immunohistochemistry for neuropeptide-Y (NPY). The cells stained by the two procedures have similar morphologies and distributions.(More)
Using conventional immunocytochemical techniques, we have examined the morphology and distribution of somatostatin-like immunoreactive neurons in the visual cortex of albino rats between the first postnatal day and maturity. In the adult, somatostatin-immunoreactive neurons were observed in layers II to VI but were concentrated in layers II and III. These(More)
Using immunocytochemistry, we have examined the morphology and distribution of vasoactive intestinal polypeptide-like immunoreactive neurons in the visual cortex of albino rats whose ages were closely spaced in time between the first postnatal day and adulthood. In the adult, immunoreactive neurons were located in layers II to VI but were concentrated in(More)
Antibodies have been raised against synthetic peptides derived from the predicted primary sequence of the human cocaine- and antidepressant-sensitive norepinephrine (NE) transporter (NET). One antibody (N430), raised and purified against a putative intracellular human norepinephrine transporter (hNET) epitope, detects hNET expression in a stably transfected(More)
The ovary is innervated by noradrenergic and peptidergic fibers. Treatment of neonatal rats with antibodies to nerve growth factor (NGF Ab) resulted in failure of the sympathetic (noradrenergic and neuropeptide-Y) nerves to develop. Partial loss of sensory innervation, represented by calcitonin gene-related peptide fibers, was also observed. Follicular(More)
Recent reports indicate that oxytocin exerts direct effects on the release of insulin and glucagon from the endocrine pancreas of the rat. The purpose of this study was to determine whether oxytocin-like immunoreactivity is present in the anglerfish islet, and if it is associated with subsets of hormone-producing cells. Antisera against oxytocin, insulin,(More)
