Conditions (iv), (v) and (vi) refer to the experiments presented in Figure 2A, i.e. lack of OAS1 mRNA upregulation following CF VZV-eGFP/ORF23 infection of hiPSC-neurons and OAS1 mRNA upregulation following IFN-α2 treatment of CF VZV-eGFP/ORF23 infected hiPSC-neurons. This evidence concerns the gene OAS1 and infection.
