Key Moments
Vitamin C may protect lungs via ACE2 pathway
SARS-CoV-2 enters cells via ACE2 receptors. Acute lung injury downregulates ACE2, worsening damage. Vitamin C may help protect this cascade.
"The SARS-CoV-2 virus enters human cells via the ACE2 receptor. Viral particles bind to the ACE2 receptor, together they are internalized into the cell."
