Consequently, a high expression profile involving proinflammatory cytokines, IL‐1, IL‐7, IL‐10, IL‐17, IL‐8, TNF‐α, and monocyte chemoattractant protein‐1, were detected both in patients with periodontitis and those with COVID‐19 (Sahni & Gupta, 2020) (Figure 1). The gene discussed is CXCL8; the disease is COVID-19.
