Figure 3

Activated CD4+ T-cells surface markers of recovered COVID-19 patients. (A) Upper: CD4+ CD38+ T-cells (n = 6). Lower: FACS representative plot. (B) Upper: CD4+ CD69+ T-cells (n = 7). Lower: FACS representative plot. (C) Upper: CD4+ CD127+ T-cells (n = 8). Lower: FACS representative plot. The ratio of CD4+ T-cells responses was measured as the mean of the percentage of the cell surface marker-positive T-cells in each group to the percentage of the cell surface marker-positive T-cells in the control group after the stimulation of PBMCs with a SARS-CoV-2 peptide pool (SP), angiotensin II (Ang II), or both of a SP and Ang II. *, p < 0.05.
