Molecular profile of parvalbumin-immunoreactive neurons in superior temporal cortex in schizophrenia

ABSTRACT: Dysregulation of pyramidal cell network function by the soma- and axon-targeting inhibitory neurons that contain the calcium-binding protein parvalbumin (PV) represents a core pathophysiological feature of schizophrenia. In order to gain insight into the molecular basis of their functional impairment, we used laser capture microdissection (LCM) to isolate PV-immunolabeled neurons from layer 3 of BrodmannM-bM-^@M-^Ys area 42 of the superior temporal gyrus (STG) from postmortem schizophrenia and normal control brains. We then extracted ribonucleic acid (RNA) from these neurons and determined their messenger RNA (mRNA) expression profile using the Affymetrix platform of microarray technology. 739 mRNA transcripts were found to be differentially expressed in PV neurons in subjects with schizop
