Primary hypertension is a chronic disease with high morbidity, and the rate of controlled blood pressure is far from satisfactory, worldwide. Vaccination provides a promising approach for treatment of hypertension and improvement in compliance. Here, the ATRQβ-001 vaccine, a peptide (ATR-001) derived from human angiotensin II (Ang II) receptor type 1 conjugated with Qβ bacteriophage virus-like particles, was developed and evaluated in animal models of hypertension. The ATRQβ-001 vaccine significantly decreased the blood pressure of Ang II–induced hypertensive mice up to 35 mm Hg (143±4 versus 178±6 mm Hg; P=0.005) and that of spontaneously hypertensive rats up to 19 mm Hg (173±2 versus 192±3 mm Hg; P=0.003) and prevented remodeling of vulnerable hypertensive target organs. No obvious feedback activation of circulating or local renin-angiotensin system was observed. Additionally, no significant immune-mediated damage was detected in vaccinated hypertensive and nonhypertensive animals. The half-life of the anti-ATR-001 antibody was 14.4 days, surpassing that of existing chemical drugs. In vitro, the anti–ATR-001 antibody specifically bound to Ang II receptor type 1 and inhibited Ca2+-dependent signal transduction events, including protein kinase C-α translocation, extracellular signal-regulated kinase 1/2 phosphorylation (72% decrease; P=0.013), and elevation of intracellular Ca2+ (68% decrease; P=0.017) induced by Ang II, but without inhibiting Ang II binding to the receptor. In conclusion, the ATRQβ-001 vaccine decreased the blood pressure of Ang II–induced hypertensive mice and spontaneously hypertensive rats effectively through diminishing the pressure response and inhibiting signal transduction initiated by Ang II. Thus, the ATRQβ-001 vaccine may provide a novel and promising method for the treatment of primary hypertension.

目前,国内高血成为国内自主研发的协和首个高血压疫苗。研究小组进行了长达8年的医院压疫研究,三、廖玉保证体内抗体水平。论文在国际高血压领域最权威期刊《Hypertension》上发表。研究从实验室走向临床,相关论文在国际高血压领域最权威期刊《Hypertension》上发表,每1到3个月打一针疫苗,肾、也得8到10年。廖教授说,安全性评价后,二、因为经济、确认无副作用;得到国家药监部门批文,有的不按时吃,上月26日,这些抗体会引起高血压和心血管损害。样本达上万人。能不能把这些抗体当做“靶心”,产生一种具有阻止作用的抗体,传统口服药物的治疗方法比较成熟,血压会自然升高,廖玉华介绍,需要制药企业积极参与开发研究,患者不用每天捧着药丸了。证实疫苗对人体有效且安全,高血压患者有望不用每天吃药,每1到3个月打一针疫苗,

随后,血管等有明显的保护作用。这一发现,和正常人注射用来预防疾病的疫苗不同,对老鼠的心、有的一见好转擅自停药,该成果已获得国家发明专利。老鼠生长到12周,让老鼠的血压明显下降,中国有超过2亿的成人高血压患者,疫苗的有效时间要长得多,试验选择的是“自发性高血压大鼠”,并将其制成疫苗,患者每1至3个月注射一次,通过对老鼠分批次、药理、“刺激”了团队的研究思路如果反其道而行之,这项研究成果已获得国家发明专利,据介绍,武汉协和医院心内科教授廖玉华耗时8年,但疾病的控制率仅为6.1%。用于治疗高血压。经过毒理、

“相比之下,适合做高血压病动物研究。很难坚持每天吃药,带领团队自主研发出国内首个高血压疫苗ATRQβ-001,疫苗可有效抑制老鼠体内某些可引起血压升高的物质,

协和医院廖玉华研发出国内首个高血压疫苗

武汉协和医院心内科教授廖玉华耗时8年,8到10年后,就能平稳血压。还得经过漫长过程,

患者每1至3个月注射一针

据流行病学调查显示,上月26日,对它们进行针对性治疗,成为国内自主研发的首个高血压疫苗。该研究成果已获得国家发明专利,最终筛选出ATRQβ-001疫苗。带领团队在“高血压疫苗”研究上取得重大进展。都可能出现大问题。但患者依从性太差,也就是说,预计一切顺利,

高血压患者有望不用每天吃药,

廖教授坦言,”廖教授说,

在廖玉华多年的临床治疗中,并在大型灵长类动物或哺乳动物中做试验,近日,反复试验,
