To enlighten the involvement of PACAP/receptors system in the control of mammal testis, we investigated the expression of PACAP and the localization of PACAP and its receptors PAC1, VPAC1, and VPAC2 in the testis of Mus musculus. By molecular and immunohistochemical investigations, we highlighted that PACAP and its receptors are widely represented in germ cells of Mus testis, particularly in spermatocytes I, spermatids, and spermatozoa, strongly suggesting their involvement in spermatogenesis process. Moreover, for the first time in the adult mouse testis we highlighted that PACAP is present within Leydig cells, as PACAP receptors, confirming its involvement in the control of steroidogenesis in mouse.

Pituitary adenylate cyclase activating polypeptide (PACAP), acting through its cognate receptors PAC1, VPAC1, and VPAC2, is a pleiotropic signaling neuropeptide of the vasoactive intestinal peptide/se...
It has been demonstrated that anterior cruciate ligament (ACL) injury-induced cartilage degeneration is the key risk factor for post-traumatic knee osteoarthritis (PTKOA).Pituitary adenylate cyclase-a...
Neurodegenerative disorders, such as Parkinson's disease (PD), are characterized by neuronal death involving, among other events, mitochondrial dysfunction and excitotoxicity. Along these lines, sever...
The pituitary adenylate cyclase-activating polypeptide (PACAP) type 1 receptor (PAC1), a class B G protein-coupled receptor (GPCR), has emerged as a promising target for treating neurodegenerative con...
Pituitary adenylate cyclase-activating polypeptide (PACAP) has emerged as an important signaling peptide in migraine pathogenesis. Recently, we have shown that the less-abundant PACAP isoform, PACAP27...
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a signaling molecule, localized in sensory and parasympathetic perivascular nerves fibres. PACAP exists i to functional iso-fo...
Vasoactive intestinal peptide (VIP) is a peptide of 28 amino acid residues that belongs to the glucagon/secretin superfamily of peptides. It is produced in different regions of the nervous...
The aim is to investigate the incidence of headache, migraine attacks and flushing after pituitary adenylate cyclase-activating peptide-38 (PACAP38) with and without treatment with sumatri...
The study aim at examining whether Sumatriptan changes the plasma values of the neuropeptides vasoactive intestinal polypeptide (VIP), calcitonin gene-related peptide (CGRP) and pituitary ...
The investigators aim is to investigate the incidence of headache and rosacea-like flushing after pituitary adenylate cyclase-activating peptide-38 (PACAP38) with and without treatment wit...
A pituitary adenylate cyclase-activating peptide receptor subtype that is found in the HYPOTHALAMUS; BRAIN STEM; PITUITARY GLAND; ADRENAL GLAND; PANCREAS; and TESTES and has a high affinity only for PACAP.
A pituitary adenylate cyclase-activating peptide receptor subtype found in LYMPHOCYTES. It binds both PACAP and VASOACTIVE INTESTINAL PEPTIDE and regulates immune responses.
A family of G-protein-coupled receptors that share significant homology with GLUCAGON RECEPTORS. They bind PITUITARY ADENYLATE CYCLASE ACTIVATING POLYPEPTIDE with high affinity and trigger intracellular changes that influence the behavior of CELLS.
A multi-function neuropeptide that acts throughout the body by elevating intracellular cyclic AMP level via its interaction with PACAP RECEPTORS. Although first isolated from hypothalamic extracts and named for its action on the pituitary, it is widely distributed in the central and peripheral nervous systems. PACAP is important in the control of endocrine and homeostatic processes, such as secretion of pituitary and gut hormones and food intake.
A pituitary adenylate cyclase-activating polypeptide receptor subtype that binds both PACAP and VASOACTIVE INTESTINAL PEPTIDE. It is found predominately in the BRAIN.
