For example, recent postmortem studies that isolate cell specific transcriptomic changes revealed 1400 differentially expressed genes in layer III and V pyramidal cells [44] and 800 differentially expressed transcripts in Layer III parvalbumin-containing interneurons [45] within the dorsolateral prefrontal cortex (DLPFC) of schizophrenia-affected brains. The gene discussed is PVALB; the disease is schizophrenia.
