VAV1 and infection: However, in contrast to stat1loxP/loxP/Vav-cre mice, in which viral replication complexes were transiently detectable at day 3 (Fig. 5b), (+) and (−) YFV-17D RNA were readily quantifiable in multiple peripheral human cell subsets in NRG-HIS mice at day 11 post infection (Fig. 7b).
