Figure 1: Elevated serum angiotensin II levels in H5N1-infected patients.
From: Angiotensin-converting enzyme 2 protects from lethal avian influenza A H5N1 infections
(a) Angiotensin II levels in the sera of healthy volunteers (Controls, n=10) and H5N1-infected patients (n=26) divided into three groups according to plasma sampling times relative to the disease onset. Angiotensin II serum levels were determined using ELISA; bars represent the median value. **P<0.01 (Mann-Whitney U test). (b) Kinetics of angiotensin II serum levels in three H5N1-infected patients (patients 4, 13, and 14). Angiotensin II levels were determined using ELISA at the indicated time points after the onset of flu symptoms.
