The invention is clinically and repeatedly researched at the animal level, and it is found that in the occurrence and development process of senile-related hypertension, a prostaglandin D2 receptor DP1 inhibits generation of active oxygen and vascular remodeling by inhibiting Th1 type inflammatory reaction, and therefore the disease of hypertension is reduced; and after DP1 is activated, the disease of senile hypertension can be relieved. The content of basic research on the pathogenesis of the senile hypertension is enriched, and a new thought is provided for more deeply exploring the essential cause of the senile hypertension. Meanwhile, DP1 can serve as a new drug target for clinically treating the senile hypertension, and a DP1 agonist and a neutralizing antibody of Th1 type cytokinescan be referred to as potential drugs for treating the senile hypertension.
