The importance of Wnt signalling for neurodegeneration in Parkinson's disease

Abstract

PD (Parkinson's disease) is a devastating progressive motor disorder with no available cure. Over the last two decades, an increasing number of genetic defects have been found that cause familial and idiopathic forms of PD. In parallel, the importance of Wnt signalling pathways for the healthy functioning of the adult brain and the dysregulation of these pathways in neurodegenerative disease has become apparent. Cell biological functions disrupted in PD are partially controlled by Wnt signalling pathways and proteins encoded by PARK genes have been shown to modify Wnt signalling. This suggests the prospect of targeting Wnt signalling pathways to modify PD progression.
