This observation was coupled with measurements of elevated circulating chemokines and cytokines among COVID-19 patients, including IL-6, IL1RA, CCL2, CCL8 CXCL2, CXCL8, CXCL9, and CXCL16, indicating an enhancement of generalised inflammation [47]. The gene discussed is CXCL9; the disease is COVID-19.
