NFKB1 and infection: The possible role of NF-κB signaling in IFN-stimulated genes (ISGs) expression has led to the conclusion that using NF-κB inhibitors, such as TPCA-1, which decrease ISGs expression, may improve productive infection of oncolytic HSV Δγ134.5 recombinants, which are devoid of ICP34.5 neurovirulence factor and whose replication is limited by protein kinase R (PKR) [71].
