Molecular Therapy-Nucleic Acids

Researchers led by Osaka University performed RNA-sequencing analysis of whole blood samples from patients with severe COVID-19 and healthy controls to evaluate differences in messenger RNA and microRNA expression. The interferon signaling pathway was found to be activated in patients with severe COVID-19, and measurement of interferon proteins in the plasma revealed that interferon-β and interferon-λ1 play an important role in the severity of COVID-19.
