Abstract：
BACKGROUND:Our previous lipidomics studies demonstrated elevated sulfatides, plasmalogens, and N-acylphosphatidylserines in the frontal cortex of schizophrenia subjects. These data suggest that there may be an abnormal function of glycosynapses in schizophrenia. We further examined the disease and anatomical specificity of these observations. METHODS:We undertook a targeted lipidomics analysis of plasmalogens, sulfatides, and N-acyl-phosphatidylserines in the frontal cortex obtained from schizophrenia, bipolar, and ALS subjects and the cerebellum of schizophrenia subjects. RESULTS:We demonstrate that sulfatides, plasmalogens, and N-acyl-phosphatidylserines are significantly elevated in the frontal cortex of patients suffering from schizophrenia and bipolar depression but not in ALS patients. These lipids were unchanged in the cerebellum of subjects with schizophrenia. CONCLUSIONS:Our data suggest that dysfunction of oligodendrocyte glycosynapses may be specific to limbic circuits in schizophrenia and that this dysfunction is also detected in bipolar depression, suggesting that these disorders possess several common pathophysiological features.
