In a study published in Current Biology today, researchers from  King's College London uncovers the precise mechanisms by which autophagy leads to cell death. The  study used a  mouse model for the polyglutamine disease dentatorubral-pallidoluysian atrophy (DRPLA), progressive acquirement of an ataxic phenotype linked to severe cerebellar cellular pathology, characterized by nuclear degeneration through nucleophagy-based LaminB1 degradation and excretion.  DRPLA is caused by ...
