The Wnt signaling pathway is one of the crucial signaling pathways that regulate many aspects of central nervous system. In this review, we tempt to depict an overall picture of the Wnt signaling with its multitude of roles in schizophrenia. If the Wnt signaling pathway plays a crucial role in the pathogenesis of schizophrenia as we suggest, a better understanding of the Wnt pathway might contribute to developing new and more effective tools for diagnosis and treatment of schizophrenia.
