The presence and functional role of vasoactive intestinal peptide in the hamster seminal vesicle were studied by a combination of structural and functional approaches. The use of an immunofluorescence staining technique in both cryostat sections and whole-mount preparations revealed that vasoactive intestinal peptide-immunoreactive nerve fibres were mainly(More)
In the present work we have investigated the effects of medium- (15 days) and long-term (2 months) castration on vasoactive intestinal peptide (VIP)-immunoreactive nerve fibres and 125I-labelled VIP binding sites in the adult hamster seminal vesicle. The density of VIP- and synaptophysin (general neuronal marker)-containing nerve fibres was determined in(More)
The importance of neuronal factors in the normal physiology of the seminal vesicles has been traditionally underestimated when compared to the trophic role of androgens. Immunohistochemical, autoradiographical and pharmacological experiments have, however, raised the possibility that neuropeptides, such as vasoactive intestinal polypeptide (VIP),(More)
The effects of angiotensin II (Ang II) on vascular smooth muscle cells (VSMC) are modulated by reactive oxygen species (ROS) and also involve integrin engagement. However, the potential link between alpha1beta1 integrin signaling with NOX system and their combined contribution to Ang II effects on VSMC have not been investigated. We aimed to elucidate the(More)
