6. CONCLUSION
Multiple pathogenic processes are involved in COVID-19 after SARS-CoV-2
infection. The associated proteins or signals ruling in the viral entry
into the host cells, viral replication in host cells, and induction of
cytokine storm might function as therapeutic targets for COVID-19.
Further elucidation of these processes and underlying mechanisms may
find novel therapeutic targets, which is a critical strategy for
developing treatments of COVID-19.
