In the spinal interneurons of a mouse model of amyotrophic lateral sclerosis (ALS), protein aggregation (red and green) is clearly visible (left), while in mice engineered to quell autophagy (right), these aggregates are completely absent.TOM MANIATIS/COLUMBIA UNIVERSITY'S ZUCKERMAN INSTITUTESee N.D.
