Immunoreactive corticotropin releasing factor (CRF) and vasopressin are colocalized in a subpopulation of the immunoreactive vasopressin cells in the paraventricular nucleus of the hypothalamus

Abstract

In the magnocellular cells of the paraventricular nucleus of hypothalamus, corticotropin releasing factor (CRF) immunoreactivity was observed in a subpopulation of vasopressin immunoreactive cells. No CRF immunostaining was observed in the supraoptic nucleus, a region with marked vasopressin staining.
