| Research Abstract |
Aripiprazole significantly potentiated nerve growth factor(NGF)-induced neurite outgrowth in PC12 cells, in a concentration-dependent manner. The 5-HT1A receptor antagonist WAY-100635, but not the dopamine D2 receptor antagonistsulpiride, blocked the effects of aripiprazole, although, only partially. Specificinhibitors of several common signaling pathways also blocked the effects of aripiprazole.Using proteomic analysis, we found that aripiprazole significantly increased levels ofthe heat shock protein Hsp90α in cultured cells.
