Fig. 4A through F shows analyses in SLAM-expressing cells and Fig. 4G through L in nectin-4 expressing cells; Fig. 5A through E shows analyses in receptor-negative hiPSC-derived neurons and Fig. 5F through J in receptor-negative hiPSC-derived astrocytes. Expecting slower infections in receptor-negative cells (50), we infected these cells at a 10-fold higher MOI than the receptor-positive cells (0.5 vs 0.05 MOI). This evidence concerns the gene NECTIN4 and infection.
