While the role of IL-6 and IL-10 in severe COVID-19 patients has been related to the acceleration of the inflammatory process and the induction of the cytokine storm, the role of CXCL10 has been associated with the recruitment of leukocytes to inflamed tissues, thus perpetuating inflammation and causing finally tissue damage (Costela-Ruiz and others 2020). The gene discussed is IL6; the disease is COVID-19.
