Receptor activity modifying protein-1 (RAMP1) is part of a three-member group (that further includes RAMP2 and RAMP3 – each encoded by a different gene) of transmembrane proteins that interact with G-protein coupled receptors (GPCRs) such as the calcitonin receptor-like receptors (CLRs)1. This interaction leads to the formation of the receptor for calcitonin gene related peptide (CGRP) and is necessary for the binding of the peptide to the receptor. The binding of RAMP2 and RAMP3 to CLR, on the other hand, creates the receptor for adrenomedullin, a peptide functionally and structurally related to calcitonin1,2.
RAMP1 (as well as the two other RAMPs) has a short intracellular domain and a single transmembrane domain. Its extracellular region contains four conserved cysteine residues that putatively form two disulfide bonds. This domain confers specificity to the receptor complex, whereas the transmembrane chain allows the association of the RAMPs with the GPCRs. In contrast to the other RAMPs, RAMP1 lacks glycosylation sites and therefore is unable to migrate to the cell surface independently. To reach the cell surface, it aggregates inside the cytoplasm and forms heterodimers with calcitonin3.
RAMP1 is highly prominent in the neuronal tissues (especially the trigeminal ganglion, striatum, cortex, olfactory bulb, dorsal root ganglion, and the spinal cord) but abundant as well in the electrical conducting system of the heart, blood vessels, and related sites1,2,4.
While not dramatically affected, RAMP1-KO mice are reported to have higher blood pressure and to suffer from repressed wound healing process, while overexpression of RAMP1 in animals leads to extravasation and vasodilation2. Interestingly, asthmatic symptoms in mice model of asthma were mitigated in mice that were RAMP1-deficient4. Furthermore mesenchymal stem cells overexpressing RAMP1 were shown to improve cardiac function and to reduce occurrences of over-thickened blood vessels5.
Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of rat RAMP1. Anti–RAMP1 (extracellular) Antibody (#ARR-021) can be used in western blot and live cell imaging applications. The antibody recognizes an extracellular epitope and is thus ideal for detecting the protein in living cells. It has been designed to recognize RAMP1 from rat and mouse samples. The antibody does not recognize RAMP1 from human samples.

深夜,保姆觉得无聊就想去楼下看电视。但是她看不了,因为楼下没有电视(因为孩子的父母不希望他们的孩子看太多垃圾)。她就打电话给孩子的父母,问是否可以在他们的卧室看电视,当然孩子的父母同意了。
但保姆又想要最后一个请求。
她问是否可以用毯子或者衣服盖住那小丑雕像,因为那使她感到很害怕。
电话沉默了一会。
(此时爸爸在和保姆通话)
他说:带孩子离开房间……
我们将会叫警察……我们从来没有什么小丑雕像。
那小丑很可能是一个从监狱逃出来的杀人犯。
电话里沉默了一会儿。
(正在跟保姆通话的孩子的父亲)说:带上孩子们,离开房子……我们会通知警察……我们没有一个小丑雕像……
孩子们和保姆被小丑谋杀了。
结果是,小丑是一个从监狱里逃出来的杀人犯。
如果你不在5分钟内转发这个贴子,这个小丑在凌晨3点时将会拿着刀站在你的床前。
我在这里发了,这就是恶魔般的小丑没有杀我的原因

慢性心功能不全的病因的防治
风湿性心瓣膜病在我国仍属慢性心力衰竭的常见病因。应用青霉素治疗链球菌感染,已使风湿热和风湿性心瓣膜病在发达国家基本绝迹。择期手术治疗风湿性心瓣膜病,有效地控制高血压以及积极防治冠脉病变与心肌缺血等病因治疗;消除心力衰竭的诱因如控制感染、避免体力过劳和精神应激等。可预防心力衰竭的发生。
收缩性心力衰竭的治疗
1、减轻心脏负荷包括减少体力活动和精神应激。严重者宜绝对卧床休息,在心功能逐步改善过程中,适当下床活动,以免卧床休息过久并发静脉血栓形成或肺炎。此外,应注意解除精神负担,必要时给予小量镇静剂。
2、限制钠盐摄入适当限制日常饮食中的钠盐摄入量,食盐量2~5g,忌盐腌制食物。应用利尿剂引起大量利尿时,钠盐限制不宜过严,以免发生低钠血症。
3、利尿剂的应用利尿剂通过抑制肾小管不同部位Na+重吸收,或增加肾小球Na+滤过,增进水、Na+排出,从而降低心室充盈压,减轻肺循环和(或)体循环瘀血所致临床症状,其疗效肯定,但对心力衰竭整体过程的影响(如生存率等)不明,长期应用利尿剂理论上可能产生下列不良作用:①降低心排血量,从而激活RAS,血浆肾素和醛固酮增高。②导致低钾血症。③降低糖耐量。④导致高尿酸血症。⑤导致高脂血症。⑥导致室性心律失常。目前利尿剂属治疗心力衰竭伴水、钠潴留患者的一线药物,大多与其他心力衰竭治疗药物(如地高辛、ACE抑制剂)联合应用,单纯舒张性心力衰竭者利尿剂宜慎用。
4、正性肌力药物的应用由于慢性心力衰竭患者心肌收缩性减弱,改善心肌收缩功能曾被认为是心力衰竭的首要治疗。正性肌力药物能使心室功能曲线左上移,增加每搏作功,降低心室充盈压,从而使扩大的心脏缩小。虽然在增加心肌收缩的同时也增加心肌能量消耗,但扩大的心脏缩小后,其心肌氧耗和冠脉血供分别较心脏扩大时降低和改善,心肌能量供需的不平衡因而并不加重,甚至有所减轻。正性肌力药减轻症状、改善运动耐量和心功分级的效果明显,但多中心随机对照慢性心力衰竭患者长期临床治疗试验结果表明除洋地黄外,大多具有增高病死率与室性心律失常发生率的倾向。ACEI则不仅减轻症状、改善运动耐量和心功分级的效果更显著,且能降低病死率和病残率。因而大多数临床医师选用ACEI作为与利尿剂联用,以治疗窦性心律的慢性心力衰竭患者。
