Immune-mediated control of a persistent viral infection. (A) NSE-CD46+, NSE-CD46+ perforin KO, and NSE-CD46+ IFN-γ KO mice were challenged i.c. with 1 × 104 PFU of MV Edmonston. Mice were monitored daily. Percent survival is indicated. Data represent at least 2 individual experiments using NSE-CD46+, NSE-CD46+ perforin KO, and NSE-CD46+ IFN-γ KO mice. (B and C) RNA was collected from whole-brain tissue of mice of the indicated genotypes. RT-qPCR data were generated using random-hexamer priming for cDNA generation, followed by qPCR using primers specific for the MV nucleoprotein and cyclophilin B as a standard. Data were analyzed using the ΔΔCT method. #, P < 0.05, Mann-Whitney U test of NSE-CD46+ controls compared to immunodeficient mice.
