Zhou Y. et al. [41] analyzed the immune parameters of patients with COVID-19, especially those with severe infection and poor outcome, and showed that they also had elevated serum concentrations of inflammation-related cytokines including IL-2, IL-7, IL-10, G –CSF, IP10, MCP1, MIP1A, and TNF-α. Here, CXCL10 is linked to COVID-19.
