Resumen de Huntingtin fibrils poke membranes

Pedro Guedes Dias, Erika L.F. Holzbaur

• A hallmark of Huntington’s disease is the presence of intracellular aggregates of mutant huntingtin, the pathological significance of which has long been debated. Using cryo-electron tomography, Bauerlein et al. reveal the fibrillary structure of huntingtin aggregates in situ and show that huntingtin fibrils interact with the endoplasmic reticulum, distorting its morphology and dynamics.
