RNASEL and infection: L*-mediated inhibition of RNase L in vivo was not analyzed for TMEV, by comparing the infection of RNase L-deficient (RNase L-/-) and RNase L +/+ mice [21] because these mice are on the C57BL/6 background and therefore rapidly clear TMEV infection through a potent H-2b-restricted cytolytic T lymphocyte response [46–48].
