FUS and infection: We found that after infection with CVB3, a neurotrophic virus, FUS was mislocalized from its normal nuclear location to the cytoplasm starting at 3 h postinfection in HeLa cells (human cervical cancer cells), NSC-34 cells (mouse motor neuron-like cells), and SH-SY5Y cells (human neuroblastoma cells) (Fig. 1A and B).
