DLG1 and schizophrenia: Several studies have reported changes in the expression of molecules associated with AMPAR trafficking in schizophrenia.33, 34 In our previous studies, as we described in the introduction, we demonstrated that the mRNA expression of DLG1 is increased in response to phencyclidine only after a critical stage of development and hypothesized that a human brain system equipped with a certain molecular cascade is responsible for this phenomenon.
