Fig. 6. Effects of ORF8 KO on HLA-I expression in human lung organoids.
A Clinical isolates of XBB.1, XBB.1.5, and Delta were inoculated into human iPSC-derived lung organoids. The percentages of HLA-I-positive cells in the lung organoids are shown. B The percentage of HLA-I-positive cells in viral N protein-positive lung organoids is shown. Assays were performed in triplicate. The presented data are expressed as the average ± SD. The statistically significant differences between XBB.1.5 and other variants were determined by a two-sided Student’s t test.
