IL-6 may act as a potential biomarker of SARS-CoV-2 as IL-6 level has been found to be increased in COVID-19 patients [79] As CoV infection can infect macrophages, microglia, and astrocytes in the CNS inducing pro-inflammatory conditions [82] and activation of immune cells, it is crucial to find the probable correlation between COVID-19 and neurological damage through immune injury. The gene discussed is IL6; the disease is COVID-19.
