Percentages of CD3+ lymphocytes producing IFN-γ, TNF-α, IL-10 or IL-17A in basal conditions (Figure 3A) tended to be higher in stroke patients on admission compared to age-matched healthy donors, but differences did not reach statistical significance (admission median (IQR) 1.29 (0.52–1.97) vs. healthy 1.14 (0.13–1.63) for IFN-γ; admission 0.19 (0.10–0.53) vs. healthy 0.10 (0.06–0.31) for TNF-α; admission 0.17 (0.10–0.42) vs. healthy 0.09 (0.06–0.15) for IL-10; admission 0.62 (0.22–1.41) vs. healthy 0.15 (0.06–0.27) for IL-17A). The gene discussed is IFNG; the disease is Stroke.
