GFAP and schizophrenia: A number of papers reported significantly decreased densities of GFAP-immunolabelled AC profiles in various cortical and subcortical brain regions in SCZ and in schizophrenia suicide completers [18, 24, 26, 27, 154, 169], while other studies found either no difference [164, 170, 171] or increased densities of GFAP immunopositive cells [149, 151, 172, 173].
