Grant number: 299891

Abstract

Huntington's disease (HD) is a devastating illness in which movement disorders (including chorea) and mental problems progress for 10-20 years after onset, and inevitably lead to death. HD is caused by an expansion in a repeating segment of DNA in a single gene and is inherited by 50% of the offspring of sufferers. Despite this strong genetic factor, we have recent evidence from a mouse model, in which the human HD gene mutation has been inserted into the mouse genome, supporting a role for environmental factors in disease onset and progression. Following on from our work showing that environmental enrichment delays disease and progression in this mouse model of HD, we are using experimental..
