Inflammation in the COVID-19 airway is due to inhibition of CFTR signaling by the SARS-CoV-2 Spike protein

This paper shows that SARS-CoV-2 Spike protein inhibits CFTR signaling in airway epithelia, leading to inflammation similar to cystic fibrosis.

Common cardiac medications potently inhibit ACE2 binding to the SARS-CoV-2 Spike, and block virus penetration into human lung cells

This study shows cardiac medications like ouabain and digitoxin inhibit ACE2 binding to SARS-CoV-2 Spike and block virus entry into human lung cells.
