Altered levels of transcription factor specificity protein 4 (SP4) and 1 (SP1) in the cerebellum, prefrontal cortex and/or lymphocytes have been reported in severe psychiatric disorders, including early psychosis, bipolar disorder, and chronic schizophrenia subjects who have undergone long-term antipsychotic treatments. SP4 transgenic mice show altered(More)
Cognitive deficits are considered a key feature of schizophrenia, and they usually precede the onset of the illness and continue after psychotic symptoms appear. Current antipsychotic drugs have little or no effect on the cognitive deficits of this disorder. Prolyl oligopeptidase (POP) is an 81-kDa monomeric serine protease that is expressed in brain and(More)
Reduced glutamatergic activity and energy metabolism in the dorsolateral prefrontal cortex (DLPFC) have been described in schizophrenia. Glycogenolysis in astrocytes is responsible for providing neurons with lactate as a transient energy supply helping to couple glutamatergic neurotransmission and glucose utilization in the brain. This mechanism could be(More)
Schizophrenia is a serious life-long disease that affects a significant part of the adult population. Although there is considerably effective medication for the positive symptoms of the disease, none are available for the associated cognitive deficits. These deficits are a core feature of schizophrenia, and they severely impair the functionality and social(More)
