Immunohistochemical studies on the roles of substance P in the rat hypothalamus: possible implication in the hypothalamic-hypophysial-gonadal axis.

abstract：:The neurohypophysial peptide hormone [Arg8]vasopressin (AVP) has well documented pressor effects in the periphery. These are mediated by vasopressin receptors (VPRs) of the V1a subtype, expressed by vascular smooth muscle cells, which induce vascular contraction when activated. AVP also has effects on the vasculature ...
