To identify potential therapeutic targets for SARS-CoV-2 and related pathogenic coronaviruses, Wei et al. conduct genome-wide CRISPR screens in Vero-E6 cells using SARS-CoV-2, MERS-CoV, and pseudoviruses presenting SARS-CoV-1 or SARS-CoV-2 spike proteins. They identify pro-viral genes and pathways, including HMGB1 and the SWI/SNF chromatin remodeling complex, that are SARS lineage and pan-coronavirus specific, respectively, and demonstrate that HMGB1 is critical for SARS lineage viral entry because it has a critical role in ACE2 expression.
