However, in the serum of SARS-CoV-2–infected macaques, we found a transient virus infection–related increase in 2 interferon-γ–driven inflammatory cytokines, CXCL10 and CXCL11, and an increase of CCL2, whereas interleukin-6 was elevated in only 1 animal (Figs. 3C–3F). The gene discussed is IL6; the disease is viral infectious disease.
