Abstract EN
Background.
Multiple interleukin (IL) family members were reported to be closely related to hypertension.
We aimed to investigate whether IL-9 affects angiotensin II- (Ang II-) induced hypertension in mice.
Methods.
Mice were treated with Ang II, and IL-9 expression was determined.
In addition, effects of IL-9 knockout (KO) on blood pressure were observed in Ang II-infused mice.
To determine whether the effects of IL-9 on blood pressure was mediated by the signal transducer and activator of the transcription 3 (STAT3) pathway, Ang II-treated mice were given S31-201.
Furthermore, circulating IL-9 levels in patients with hypertension were measured.
Results.
Ang II treatment increased serum and aortic IL-9 expression in a dose-dependent manner; IL-9 levels were the highest in the second week and continued to remain high into the fourth week after the treatment.
IL-9 KO downregulated proinflammatory cytokine expression, whereas it upregulated anti-inflammatory cytokine levels, relieved vascular dysfunction, and decreased blood pressure in Ang II-infused mice.
IL-9 also reduced smooth muscle 22α (SM22α) expression and increased osteopontin (OPN) levels both in mice and in vitro.
The effects of IL-9 KO on blood pressure and inflammatory response were significantly reduced by S31-201 treatment.
Circulating IL-9 levels were significantly increased in patients with the hypertension group than in the control group, and elevated IL-9 levels positively correlated with both systolic blood pressure and diastolic blood pressure in patients with hypertension.
Conclusions.
IL-9 KO alleviates inflammatory response, prevents phenotypic transformation of smooth muscle, reduces vascular dysfunction, and lowers blood pressure via the STAT3 pathway in Ang II-infused mice.
IL-9 might be a novel target for the treatment and prevention of clinical hypertension.
