Widespread occurrence of intranuclear atrophin-1 accumulation in the central nervous system neurons of patients with dentatorubral-pallidoluysian atrophy

Abstract excerpt

Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant neurodegenerative disorder caused by a CAG repeat expansion. In the present study of DRPLA, we have demonstrated immunohistochemically that diffuse accumulation of mutant atrophin-1 in the neuronal nuclei, rather than the formation of neuronal intranuclear inclusions (NIIs), was the predominant pathologic condition and involved a wide range of...
