objective(s) recent studies on human indicate that the introduction of therapeutic use of tolerogenic dendritic cell (dc) for chronic inflammatory conditions is imminent. for the purpose of defining cgrp potency in tolerogenic dc production, we investigated the phenotype and il-'2 production of dcs generated from the monocytes of rheumatoid arthritis (ra) patients in the presence of the ca...

It is known that the neural system plays a fundamental role in neovascularization. A neuropeptide, calcitonin gene-related peptide (CGRP), is widely distributed in the central and peripheral neuronal systems. However, it remains to be elucidated the role of CGRP in angiogenesis during ischemia. The present study examined whether endogenous CGRP released from neuronal systems facilitates revascu...

Calcitonin-gene-related peptide (CGRP) is a 37-amino-acid vasodilatory peptide, of which two isoforms, alpha CGRP and beta CGRP, have been described. The use of C-terminal fragments of CGRP peptide, such as human alpha CGRP-(8-37), has led to the pharmacological subdivision of CGRP receptors into CGRP-1 [high potency for binding of human alpha CGRP-(8-37)] and CGRP-2 (lower potency) receptors. ...

Historically, calcitonin gene-related peptide (CGRP) receptors have been divided into two classes, CGRP(1) and CGRP(2). After the cloning of calcitonin receptor-like receptor (CLR) and receptor activity-modifying proteins (RAMPs), it became clear that the CGRP(1) receptor was a complex between CLR and RAMP1. It is now apparent that the CGRP(2) receptor phenotype is the result of CGRP acting at ...

Previous studies have demonstrated positive-inotropic effects of calcitonin gene-related peptide (CGRP), but the mechanisms remain unclear. Therefore, two experiments were performed to determine the physiological correlates of the positive-inotropic effects of CGRP. Treatments designed to antagonize the effects of physiologically active CGRP₁₋₃₇ included posttreatment with CGRP₈₋₃₇ and pretreat...

Calcitonin gene-related peptide (CGRP; official name CALCA) has a variety of functions and exhibits both angiogenic and anti-inflammatory properties. We previously reported the angiogenic effects of the CGRP family peptide adrenomedullin in oxygen-induced retinopathy; however, the effects of CGRP on ocular angiogenesis remain unknown. Herein, we used CGRP knockout (CGRP(-/-)) mice to investigat...

CGRP, which coexists with acetylcholine in trigeminal motoneurons, could be one of the regulatory anterograde factors responsible for the enhanced expression of AChR subunits in neuromuscular junction. It has been also shown that low level of thyroid hormone plasma concentration has influence on the transitional development of muscle fibers and related motoneurons through a sever reduction in A...

Objective(s): Calcitonin gene related peptide (CGRP) receptors are widely distributed in the central nervous system. The aim of this study was to investigate the effects of intracerebroventricular (ICV) injection of CGRP on pain behavioral responses and on levels of monoamines in the periaqueductal gray area (PAG) during the formalin test in rats.Materials and Methods: Twenty-four male rats wer...
