To evaluate the potential of miR-223-3p to modulate the inflammatory response during SARS-CoV infection, mRNA expression levels of relevant proinflammatory cytokines (IL-6, IL-1ß) and chemokines (CCL2, CXCL10, and CXCL2) were analyzed by qPCR (Fig. 5). Here, CCL2 is linked to severe acute respiratory syndrome.
