Defensive behaviour and predatory behaviours appear normal in these knockout mice, [14] but there is evidence that social motivation or awareness is reduced. [15] The AVPR1B antagonist, SSR149415, has been shown to have anti-aggressive actions in hamsters [ 16 ] and anti-depressant- and anxiety (anxiolytic)-like behaviors in rats. [ 17 ]
Also, unlike vasopressin 1b receptor and oxytocin knockout mice, AVPR1A knockout mice have a normal Bruce effect (appropriate failure of pregnancy in presence of novel male). [ 17 ] Although activation of AVPR1A is a major mediator of anxiogenesis in males, it is not in females.
The Brattleboro rat is a strain of laboratory rat descended from a litter born in West Brattleboro, Vermont in 1961 without the ability to produce the hormone vasopressin, which helps control kidney function. The rats' lack of vasopressin was the result of a naturally occurring genetic mutation. [citation needed]
The actions of vasopressin are mediated by stimulation of tissue-specific G protein-coupled receptors (GPCRs) called vasopressin receptors that are classified into the V 1 (V 1A), V 2, and V 3 (V 1B) receptor subtypes. [1]

The willingness of the female rats to access males was considered a direct measure of the females' levels of sexual motivation. An increase in vasopressin has been observed in female rats which have just given birth. Vasopressin is associated with aggressive and hostile behaviours, and is postulated to decrease sexual motivation in females.
Vasoactive intestinal peptide, also known as vasoactive intestinal polypeptide or VIP, is a peptide hormone that is vasoactive in the intestine. VIP is a peptide of 28 amino acid residues that belongs to a glucagon/secretin superfamily, the ligand of class II G protein–coupled receptors. [5]
Copeptin (also known as CT-proAVP) is a 39-amino acid-long peptide derived from the C-terminus of pre-pro-hormone of arginine vasopressin, neurophysin II and copeptin. . Arginine vasopressin (AVP), also known as the antidiuretic hormone (ADH), is encoded by the AVP gene and is involved in multiple cardiovascular and renal pathways and abnormal level of AVP are associated with various
