    Snippet: In order to determine whether TGEV induces FcRn expression in IPEC-J2 cells, live or UV-inactivated TGEV at a multiplicity of infection (MOI) of 1 was used to inoculate IPEC-J2 cells, which were then harvested for FcRn analysis at 12, 24, 36, and 48 hpi by RT-qPCR and Western blot (Figures 1B,C) . TGEV induced FcRn mRNA expression about two fold higher at 24, 36, and 48 hpi, and the elevation in protein levels correlated with the increased mRNA. .....
    Document: In order to determine whether TGEV induces FcRn expression in IPEC-J2 cells, live or UV-inactivated TGEV at a multiplicity of infection (MOI) of 1 was used to inoculate IPEC-J2 cells, which were then harvested for FcRn analysis at 12, 24, 36, and 48 hpi by RT-qPCR and Western blot (Figures 1B,C) . TGEV induced FcRn mRNA expression about two fold higher at 24, 36, and 48 hpi, and the elevation in protein levels correlated with the increased mRNA. However, UV-inactivated viral treatment resulted in only a 1.3-fold up-regulation of FcRn expression compared with that in simulated infected cells, indicating that the replicating virus is more effective than the UV-inactivated virus.
