Folic acid restricts SARS-CoV-2 invasion by methylating ACE2
The current COVID-19 pandemic is motivating us to demonhorns edge elucidate the molecular mechanism of SARS-CoV-2 invasion and find methods for decreasing its transmissibility.We found that SARS-CoV-2 could increase the protein level of ACE2 in mice.Folic acid and 5-10-methylenetetrahydrofolate reductase (MTHFR) could promote the methylation of the
