Repression of liver-specific hepatitis B virus enhancer 2 activity by adenovirus E1A proteins.

abstract：:The question of whether any mammalian cells are able to mount an effective RNA interference-mediated antiviral innate immune response has remained highly controversial. In this Gem, I review recent data addressing this important issue and propose a testable hypothesis that can explain many of the apparently contradict...
