The aim of this study was to examine the role played by substance P and calcitonin gene-related peptide (CGRP) within the dorsal horn of the spinal cord in engagement of antinociception evoked by dexmedetomidine (DEX). Paw withdrawal threshold (PWT) to mechanical stimulation was determined after chronic intrathecal infusion of DEX and enzyme-linked immunosorbent assay (ELISA) was employed to ex...
Calcitonin gene-related peptide (CGRP) promotes osteoblast recruitment and osteogenic activity. However, no evidence suggests that CGRP could affect the differentiation of stem cells toward osteoblasts. In this study, we genetically modified adipose-derived stem cells (ADSCs) by introducing the CGRP gene through adenoviral vector transduction and investigated on cellular proliferation and osteo...
The neurotransmitter calcitonin gene-related peptide (CGRP) is enriched in the adult rat trigeminal visceral projection to the cerebral arteries compared both to other neurotransmitters in this projection and to the percentage of CGRP-positive trigeminal cells projecting to cutaneous targets. In colchicine-treated ganglia approximately 30% of adult trigeminal ganglion cells projecting to the mi...
BACKGROUND The infrapatellar fat pad (IPFP) has been implicated as a possible source of osteoarthritis (OA) development and knee pain due to the production of inflammatory mediators and the existence of nerve fibers within this structure. Calcitonin gene-related peptide (CGRP) is a vasodilatory neuropeptide that is localized to joint tissues and has recently been implicated in the development o...
We previously described the protection by calcitonin gene-related peptide (CGRP) against hypoxic pulmonary hypertension. Here, we examine the roles of its putative receptor RDC-1 and receptor activity-modifying protein (RAMP) 1 in mediating this protection by selectively inhibiting their synthesis. RAMP1 is an accessory protein for another putative CGRP receptor, calcitonin receptor-like recept...
Calcitonin gene-related peptide (CGRP) is thought to be a prominent neuropeptide in cardiovascular regulation and neuroimmune modulation. There are two isoforms of CGRP (alphaCGRP and betaCGRP), and the main CGRP receptors are probably composed of a calcitonin receptor-like receptor (CLR) and a receptor activity-modifying protein (RAMP)1. However, the physiological functions of CGRP that are me...
Fetal pulmonary blood flow is regulated by various vasoactive substances. One, calcitonin gene-related peptide (CGRP), increases pulmonary blood flow. We examined four key physiological mechanisms underlying this response using the blocker drugs CGRP receptor blocker (CGRP(8-37)), nitric oxide synthase inhibitor [N(omega)-nitro-L-arginine (L-NNA)], adenosine triphosphate-dependent potassium (K(...
Calcitonin gene-related peptide (CGRP) is a neuropeptide that has potent vasodilator properties and is involved in various behavioral disorders. The relationship between CGRP and depression-like behavior is unclear. In this study, we used chronically stressed mice to investigate whether CGRP is involved in depression-like behavior. Each mouse was exposed to restraint and water immersion stress ...
Recently we demonstrated that sensory denervation with the neurotoxin capsaicin worsened the inflammation in an acute and chronic model of experimental colitis, which suggests a protective role of sensory nerve fibers during gut inflammation. Because we could demonstrate that sensory neuropeptides like Calcitonin gene-related peptide (CGRP) and substance P (SP) are released from sensory nerve f...
Calcitonin gene-related peptide (CGRP), one of the most potent endogenous vasodilators known, has been implicated in vascular adaptations and placental functions during pregnancy. The present study was designed to examine the existence of CGRP-A receptor components, the calcitonin receptor-like receptor (CRLR) and receptor activity-modifying protein 1 (RAMP1), in the human placenta and the vaso...
