Targeting Viral and Cellular Cysteine Proteases for Treatment of New Variants of SARS-CoV-2 [PDF]
The continuous emergence of SARS-CoV-2 variants caused the persistence of the COVID-19 epidemic and challenged the effectiveness of the existing vaccines. The viral proteases are the most attractive targets for developing antiviral drugs.

Host Serine Proteases: A Potential Targeted Therapy for COVID-19 and Influenza
The ongoing pandemic illustrates limited therapeutic options for controlling SARS-CoV-2 infections, calling a need for additional therapeutic targets. The viral spike S glycoprotein binds to the human receptor angiotensin-converting enzyme 2 (ACE2) and ...

SPINK6 inhibits human airway serine proteases and restricts influenza virus activation
SPINK6 was identified in human skin as a cellular inhibitor of serine proteases of the KLK family. Airway serine proteases are required to cleave hemagglutinin (HA) of influenza A viruses (IAVs) to initiate an infection in the human airway.
