Interleukin 17A and Toll-like Receptor 4 in Patients with Arterial Hypertension.

Background/aims: Immune responses are involved in arterial hypertension. An observational cross-sectional case control study was conducted to estimate the association between Toll-like receptor 4 (TLR4) expression and interleukin (IL)-17A serum levels in patients with controlled and non-controlled hypertension.

Methods: We have enrolled 105 non-complicated otherwise healthy hypertensive patients: 53 with well-controlled blood pressure and 52 non-controlled.
