Moreover, the downregulation of myelin-related and oligodendrocyte genes such as proteolipid protein 1 (PLP1), transferrin (TF), oligodendrocyte transcription factor 1 (OLIG1), and upregulation of myelin basic protein (MBP) were reported in the PFC of patients with schizophrenia [71]. Here, PLP1 is linked to schizophrenia.
