Despite this, the results from increasing numbers of studies suggest that zinc may have an inhibitory effect on some viral infections including SARS-CoV2, potentially through the regulation of viral RdRp and 3CL protease proteins as well as host IFNs, IL-6, ICAM cytokines, NK cells, and CD4+/CD8+ T cells as shown in Figure 1. Here, IL6 is linked to viral infectious disease.
