Transcriptional analysis carried out in both A549-hACE2 and CaLu-3 cells showed that compared with Mock-infected samples, SARS-CoV-2 slightly, but not significantly increased SNCA expression at early time-intervals (24 h) post-infection, which was not modified by IFN-β pretreatment (Fig. 1A). Here, SNCA is linked to infection.
