Adrenomedullin (AM) and calcitonin gene-related peptide (CGRP) are related peptides with distinct pharmacological profiles. Calcitonin-receptor-like receptor (CRLR, now known as CL) can function as either an AM receptor or a CGRP receptor, when cotransfected with receptor-activity-modifying proteins (RAMPs) that define ligand-binding specificity. The aim of the present study was to determine th...
Calcitonin gene-related peptide (CGRP) was isolated from an extract of the intestine of the cod Gadus morhua. The primary structure of this 37-amino acid peptide was established as follows: ACNTA TCVTH RLADF LSRSG GIGNS NFVPT NVGSK AF-NH2. The peptide shows close structural similarities to other nonmammalian (3-4 amino acid substitutions) and mammalian (5-8 amino acid substitutions) CGRPs, and ...
1. Heterogeneity in the receptors for the neuropeptide calcitonin gene-related peptide (CGRP) has been apparent for nearly 20 years. This is most clearly manifested in the observation of CGRP(8-37)-sensitive and -insensitive populations of CGRP-activated receptors. The pA(2) values for CGRP(8-37) in excess of 7 are widely considered to be the result of antagonism of CGRP(1) receptors, whereas t...
Calcitonin gene-related peptide (CGRP) and adrenomedullin (AM) are potent vasodilators and exert positive chronotropic and inotropic effects on the heart. Receptors for CGRP and AM are calcitonin receptor-like receptor (CLR)/receptor-activity-modifying protein (RAMP) 1 and CLR/RAMP2 heterodimers, respectively. The present study was designed to delineate distinct cardiovascular effects of CGRP a...
Recent evidence indicates a key role for the neuropeptide calcitonin gene-related peptide (CGRP) in migraine pain, as demonstrated by the strong analgesic action of CGRP receptor antagonists, although the mechanisms of this effect remain unclear. Most trigeminal nociceptive neurons releasing CGRP also express ATP-activated purinergic P2X3 receptors to transduce pain. To understand whether the C...

Calcitonin gene related peptide (CGRP) has a key role in migraine and recently CGRP receptor antagonists have demonstrated clinical efficacy in the treatment of migraine. However, it remains unclear where the CGRP receptors are located within the CGRP signaling pathway in the human trigeminal system and hence the potential antagonist sites of action remain unknown. Therefore we designed a study...
RIA of nonpregnant rat uterus extracts showed 0.68 +/- 0.08 pmol/g adrenomedullin (ADM) and 3.23 +/- 0.08 pmol/g calcitonin gene-related peptide (CGRP). In the pregnant (20 days gestation) uterus, the ADM content was 0.90 +/- 0.17 pmol/g, and CGRP could not be detected. ADM messenger RNA was detected at high levels in the uterus, with a 1.8-fold increase in expression in pregnancy. Pharmacologi...
OBJECTIVES Sensory nerve fibres (NFs) contain two major neuropeptides, substance P (SP) and calcitonin gene-related peptide (CGRP). The pro-inflammatory role of SP is known, while CGRP has anti-inflammatory activities by inhibiting T helper type 1 cytokines, TNF secretion and leucocyte proliferation. We demonstrated the increase of SP-positive NFs in RA as compared with OA. This study investiga...
مقدمه: پپتید مرتبط به ژن کلسیتونین (cgrp) یک نوروپپتید 37 اسید آمینه ای است که توسط فرایند ویژه ی بافتی از ژن کلسیتونین تولید میشود و تولید عمده ی آن در بافت های اعصاب مرکزی و محیطی گونه های مهره داران و غیرمهره داران است. cgrp در سازگاری های پیوندگاه عصبی ـ عضلانی نقش مهمی دارد. در این پژوهش اثر تمرین های استقامتی و مقاومتی بر میزان cgrp در عضلات تند انقباض (درشت نی قدامی) و کند انقباض (...
