Of the IFNs, type I IFN is mostly expressed in the intestinal hematopoietic cell compartment rather than in the epithelium where RV primarily replicates [26] . In addition, IFN sensitivity of RVs encoding full-length "functional" NSP1 proteins also occurs in specific cell lines, possibly reflecting NSP1's inability to target host innate factors across different species [49] . Remarkably, in addition to these viral effects in infected cells, RV also potently inhibits STAT1 phosphorylation in uninfected bystander cells in response to different types of IFNs (5) . The active human IFN response to these heterologous RV vaccines suppresses their replication sufficiently to restrict pathogenicity and reactogenicity but not so much that the generation of effective RV immunity is suppressed. ./cache/cord-282246-wyanwvxa.txt ./txt/cord-282246-wyanwvxa.txt
