Research Abstract |
Studies have provided evidence for abnormalities of the GABAergic system in schizophrenia. Cannabinoid receptors may play a role in modulating GABAergic neurons. In this study, we have performed the genetic analysis of the GABAergic neural transmission and the cannabinoid pathway in the pathophysiology of schizophrenia. We examined the association of genetic variation with the disease and the alteration of gene expression in post-mortem schizophrenic brain. We found the evidence that a number of the genes in these signaling pathways are related to the disease. In addition, we conducted a series of behavioral tests in knockout mice. In behavioral experiments, knockout mice of the genes have multiple schizophrenia-like defects such as hypoactivity and reduced social interaction. The results implicate GABAergic and cannabinoid-related dysfunctions as a key component of the molecular mechanism of schizophrenia.
