摘要
During the past three decades, Wingtess/Int （Wnt）signaling has emerged as an essential regu{ator crucial for neuronal development and maintenance （Inestrosa and Arenas, 201_0）. In addition, Wnt signal- ing was recently shown to be involved in the regula- tion of synaptic function and plasticity, which is critical for learning and memory （Oliva et aL, 2013）. Deregulation of Wnt signaling has been proposed as a key contributor to the pathogenesis of neurode- generative disorders including Alzheimer＇s disease （AD） and Parkinson＇s disease （PD）. This increasing knowledge of the specific roles of Wnt signaling cascades during different stages of life has suggested innovative therapeutic strategies for the treatment of neurodegenerative diseases.
