Results: In the unstimulated saliva of stroke patients, significantly higher levels of pro-inflammatory cytokines (IL-1β (p=0.0003), TNF-α (p≤0.0001), TNF-β; (p≤0.0001)), anti-inflammatory cytokines (IL-1ra (p≤0.0001), TRAIL (p=0.0206)), Th1 cytokines (IFN-γ (p≤0.0001), IL-2Rα (p=0.0021) and IL-12 (p40) (p≤0.0001)) and Th2 cytokines (IL-6 (p=0.0023)) were found compared to healthy participants. This evidence concerns the gene IL1B and Stroke.
