Additionally, studies of transcriptomic expression profiles in patients with COVID-19 in samples of mononuclear peripheral blood cells, bronchoalveolar lavage fluid and nasopharyngeal swabs show increased expression levels of IL-6 and other cytokines, such as IL-10, IL-8, CXCL10/IP-10, CCL2/MCP-1 and CCL3/MIP-1A, as well as an increase in the expression levels of ACE2 and CRP [32]. Here, CXCL8 is linked to COVID-19.
