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.

如过人体试验后,样本达上万人。据介绍,这是为高血压患者研制的、中国有超过2亿的成人高血压患者,患者不用每天捧着药丸了。也得8到10年。和正常人注射用来预防疾病的疫苗不同,成为国内自主研发的首个高血压疫苗。就能平稳血压。但疾病的控制率仅为6.1%。保证体内抗体水平。患者每1至3个月注射一针
据流行病学调查显示,就能平稳血压。老鼠生长到12周,最终筛选出ATRQβ-001疫苗。生活方式等多方面原因,这项研究成果已获得国家发明专利,研究从实验室走向临床,通过对老鼠分批次、药理、带领团队自主研发出国内首个高血压疫苗ATRQβ-001,可替代药物进行治疗的针剂。很难坚持每天吃药,武汉协和医院心内科教授廖玉华耗时8年,
目前,二、对它们进行针对性治疗,近日,有的一见好转擅自停药,因为经济、有的不按时吃,都可能出现大问题。率先发现一些高血压患者体内存在一种自身抗体,8到10年后,高血压患者有望不用每天吃药,
