FUS and amyotrophic lateral sclerosis: The observation that ALS MuVs act on RNA transport, that overexpression of wild‐type FUS in MuV‐recipient cells resulted in increased recipient cell death, and that RNA transport protein mislocalization is partially corrected and cell death reduced when FUS expression was knocked down in recipient cells, is consistent with a body of literature suggesting an RNA processing blockade mechanism in ALS MN.36, 37
