Huntingtin reduction results in altered nuclear structure and heterochromatic instability.

ABSTRACT: Huntington's disease (HD), a fatal neurodegenerative disease, arises due to a CAG repeat expansion in the huntingtin (HTT) gene. Non-pathogenic wild type HTT (wtHTT) is essential for neurodevelopment as well as many vital cellular functions within the adult brain; however, the consequences of wtHTT reduction in adulthood and particularly in extrastriatal regions of the brain have not been well characterized. Understanding the implications of wtHTT loss is essential as numerous genetic therapies for HD non-specifically reduce the expression levels of both mutant and wtHTT. The aim of the current study was to characterize the effect of wtHTT reduction from the whole cell to synaptic level in primary hippocampal neurons using conventional and super-resolution imaging methods. Our results iden
