Oct-6 Immunoreactivity in Paraffin-embedded Tissue from Control, Schizophrenic, Bipolar Disorder and Major Depression. Oct-6 immunoreactivity was observed in hippocampal subfields CA4, CA3 and CA1 in controls (CON A – C), schizophrenics (SCH D – F), bipolar disorder (BP G – I) and major depression (MD J – L). Oct-6 immunoreactivity was observed in groups in a cytoplasmic/perinuclear fashion (arrowheads). Oct-6-positive cells had the morphological appearance of pyramidal neurons. Immunoreactivity is visible in the apical dendrites of some neurons (arrows in (H) and (K)) Scale bars = 50 μm
