In our study, besides the changes in parvalbumin expression, the MK-801 treatment increased the expression of astrocytic and microglial cell markers in the mPFC (Gomes et al., 2015b), similar to what has been observed in post-mortem brain of schizophrenia patients (Radewicz et al., 2000; Catts et al., 2014). The gene discussed is PVALB; the disease is schizophrenia.
