To assess the central effect on peripheral BDNF, we measured peripheral BDNF content in the serum of schizophrenic patients. BDNF protein levels were determined in fresh serum of chronic schizophrenic patients and healthy control volunteers. BDNF levels were significantly reduced in the serum of schizophrenic patients (p<0.001, Mann-Whitney's U-test). Antipsychotic dose did not correlate with serum BDNF levels. Moreover, chronic administration of antipsychotic drugs failed to decrease serum BDNF levels in rats. Abnormal levels of BDNF are evident not only the brain of schizophrenic patients, but also in their peripheral blood. BDNF and epidermal growth factor (EGF) are known to be liberated from platelets. A similar trend of patients was seen in serum EGF levels and correlated with serum BDNF levels. These observations suggest a potential deficit in neurotrophic factor release in patients with schizophrenia.}, pages = {436--444}, title = {慢性分裂病患者における血小板からの脳由来神経栄養性因子の放出異常}, volume = {116}, year = {2002} }
