Calcitonin gene-related peptide (CGRP) is a major neurotransmitter and CGRP-containing primary sensory neurons play an important role in nociception and potent vasodilation. CGRP-containing nerves in mesenteric arteries are decreased in pathological animal models (hypertension, diabetes, and atherosclerosis). In apolipoprotein E–knockout mice, which have atherosclerosis and peripheral sen...
Calcitonin gene-related peptide (CGRP) was found to stimulate renin secretion in vivo in normal human volunteers. Moreover, CGRP stimulated the release of renin in vitro from isolated rat renal juxtaglomerular cells (half-maximal effective concentration [EC50] 100 nM) concomitant with stimulation of cAMP production (EC50 60 nM). Immunoreactive CGRP was recognized in rat renal cortical nerve fib...
Abstract Calcitonin gene-related peptide (CGRP) has only recently emerged as a potential target in posttraumatic headache. To our knowledge, this is the first description of patient with persistent headache following severe traumatic head injury who been treated CGRP receptor monoclonal antibody erenumab. A 56-year-old man presented 30-year history frequent migraine-like headaches high-voltage ...
BACKGROUND Calcitonin gene-related peptide (CGRP) is a 37-amino-acid vasodilatory neuropeptide that binds to receptor activity-modifying protein 1 (RAMP1) and the calcitonin receptor-like receptor (CLR). Clinical and preclinical evidence suggests that CGRP is associated with hip and knee joint pain; however, the regulation mechanisms of CGRP/CGRP receptor signaling in synovial tissue are not fu...
The purpose of the present study was to investigate the effects of intracavernosal injections of adrenomedullin (ADM) and calcitonin gene-related peptide (CGRP), two structurally similar peptides, on penile erection in the anesthetized cat. Erectile responses to ADM and CGRP were compared with responses to a standard drug combination (1.65 mg papaverine, 25 microg phentolamine, and 0.5 microg p...
BACKGROUND AND OBJECTIVE Clinical and experimental studies have revealed a central role of calcitonin gene-related peptide (CGRP) in primary headaches. The role of extracellular signal-regulated kinase 1 and 2 (ERK1/2) in neuronal and glial cell expression of CGRP- immunoreactivity (-ir) in rat trigeminal ganglia was studied with an organ culture method. EXPERIMENTAL PROCEDURES Sections of ad...
پیشرفت های اخیر در زمینه مهندسی نانوساختارها و طراحی در سطوح مولکولی منجر به توسعه کاربرد نانوزیست مواد در ژن رسانی، دارورسانی، مهندسی بافت و تصویربرداری شده است. در این میان نانو زیست مواد مبتنی بر پپتیدها به دلیل تنوع ساختاری و انعطاف پذیری در طراحی، توجهات بسیاری را به خود جلب کرده اند. ژن درمانی انتقال ژن جدید به داخل سلول های یک فرد بیمار جهت درمان است. مانع اصلی انتقال موفقیت آمیز ژن به س...
CONTEXT Increased plasma levels of glucose-dependent insulinotropic polypeptide (GIP), calcitonin CT gene-related peptide (CGRP)-I, and procalcitonin (Pro-CT) are associated with obesity. Adipocytes express functional GIP receptors and the CT peptides Pro-CT and CGRP-I. However, a link between GIP and CT peptides has not been studied yet. OBJECTIVE The objective of the study was the assessmen...
یکی از مهمترین عوامل کاهش محصولات کشاورزی، آسیب های ناشی از حمله قارچ های پاتوژن به گیاهان زراعی است. غشاء پلاسمایی قارچ، هدف بزرگترین گروه پروتئین های ضدقارچی می باشد. بیش از 500 پروتئین طبیعی که با غشاء قارچ برهمکنش می کنند گزارش شده است. این پروتئین ها منجر به شکل گیری منفذ، جریان ترکیبات سلولی به سمت خارج و در نتیجه تغییر در پتانسیل غشاء می شوند. یکی از مهمترین پروتئین ها، defensin ها می با...
Calcitonin gene-related peptide (CGRP) has a potent vasodilatory effect that is mediated by specific receptors predominantly coupled to the activation of adenylate cyclase. The effects of volatile anesthetics on CGRP-induced vasodilation are unclear. We studied the effects of sevoflurane and isoflurane on CGRP-induced vasodilation in pithed rats and CGRP receptor-mediated responses in SK-N-MC c...
