AGO2 and COVID-19: The inhibition of miRNA biogenesis during SARS-CoV-2 infection was considered to be the most likely underlying reason, as supported by a study by Mousavi et al., who noted that AGO2, DICER, and DROSHA were downregulated in COVID-19 patients compared to controls [65] and suggested that viruses may interact with the miRNA biogenesis pathway [44,46].
