0:51:02: Single-cell RNA sequencing was used to determine which cell types express mx1 and ifi27.
0:51:31: An ATAC-sequencing experiment showed that the mx1 gene has more open chromatin than ifi27, potentially explaining its rapid induction.
0:52:22: Similar results were found in patients admitted to the hospital with COVID-19.
0:52:53: The potential use of mx1 and ifi27 as biomarkers for other respiratory infections is discussed.
