最近的研究表明,先天免疫和适应性免疫都有助于高血压。包括巨噬细胞和T细胞在内的炎症细胞在血管壁上积聚,特别是在血管周围脂肪和肾脏中。缺乏淋巴细胞的小鼠对高血压的发展有抵抗力,T细胞的过继性转移可以恢复高血压对血管紧张素II和doca盐的反应。免疫调节剂在改善实验性高血压终末器官损伤和血压升高方面具有不同但通常有益的作用。高血压刺激免疫反应的机制尚不清楚,但可能涉及激活适应性免疫的新抗原的形成。鉴定这些新抗原并了解它们是如何形成的,可能有助于预防和治疗这种广泛和毁灭性的疾病。
Recent studies have shown that both innate and adaptive immunity contribute to hypertension. Inflammatory cells, including macrophages and T cells accumulate in the vessel wall, particularly in the perivascular fat, and in the kidney. Mice lacking lymphocytes are resistant to development of hypertension, and adoptive transfer of T cells restores hypertensive responses to angiotensin II and DOCA-salt challenge. Immune modulating agents have variable, but often-beneficial effects in ameliorating end-organ damage and blood pressure elevation in experimental hypertension. The mechanisms by which hypertension stimulates an immune response remain unclear, but might involve formation of neo-antigens that activate adaptive immunity. Identification of these neo-antigens and understanding how they form might prove useful in prevention and treatment of this widespread and devastating disease.
