Disease relevance of Avpr1b

 

Psychiatry related information on Avpr1b

  • Preliminary evidence suggests that female V1B receptor knockout mice could also have social memory deficits [4].
  • In this study, we characterized more thoroughly the social behavior of vasopressin 1b receptor null (V1bR-/-) mice [5].
  • This difference in behavior is not explained by an anosmic condition as there were no differences between V1bR-/- and V1bR+/+ mice in their abilities to detect a cookie buried in clean bedding, or in their ability to perform in an operant conditioning task using a fully automated liquid dilution olfactometer [5].
  • As such, antagonists of the CRF1 and V1b receptor subtypes are being developed as potential treatments for affective disorders [6].
 

High impact information on Avpr1b

  • AVP-induced ACTH release from primary cultured pituitary cells in V1bR-/- mice was also blunted [7].
  • Fos-mapping within chemosensory responsive regions suggests that the behavioral deficits in V1bR knockout mice are not due to defects in detection and transmission of chemosensory signals to the brain [3].
  • A radioligand binding study showed that SR49059 and OPC-21268 potently inhibited [3H]AVP binding to the cloned mouse V1a receptor, with Ki values of 27 and 510 nM, respectively, whereas SSR149415 potently inhibited [3H]AVP binding to the cloned mouse V1b receptor with a Ki value of 110 nM [8].
  • Moreover, PPI deficits observed in the V1bR KO mice are significantly reversed by atypical antipsychotics such as risperidone and clozapine but not by a typical neuroleptic haloperidol, like in schizophrenic patients [9].
  • V1bR KO mice also showed a decrease in basal levels of extracellular dopamine (DA) in the medial prefrontal cortex, which is thought to be an important brain region for PPI [9].
 

Biological context of Avpr1b

 

Associations of Avpr1b with chemical compounds

  • To investigate the role of Avp in the hypothalamic-pituitary-adrenal axis response to stress, we measured plasma ACTH and corticosterone (CORT) levels in Avpr1b knockout (KO) mice and wild-type controls in response to two acute (restraint and insulin administration) and one form of chronic (daily restraint for 14 d) stress [1].
  • Among these three subtypes, the vasopressin V1b receptor is specifically expressed in pituitary corticotrophs and mediates the stimulatory effect of vasopressin on ACTH release [7].
  • In order to confirm the identity of the sequence, the V3/V1b receptor cDNA was cloned and stably expressed in CHO-AA8 Tet-Off cells under the control of tetracycline [11].
  • These effects were similar to those obtained with the V1b receptor antagonist SSR149415 (3-10 mg/kg, p.o.), diazepam (1 mg/kg, p.o.) and buspirone (10 mg/kg, p.o.). Fluoxetine and SSR240600 were devoid of effects in this test [12].
  • In V1bR-/- mice, OT-induced ACTH release was significantly inhibited by CL-14-26 at 10(-8) m and completely inhibited at 10(-7)m. These results indicate that OT induces the ACTH response via OT and V1b receptors inV1bR+/+ mice but via only OT receptors in V1bR-/- mice [13].
 

Other interactions of Avpr1b

  • Acute restraint (30 min) increased plasma ACTH and CORT to a similar level in both the Avpr1b mutant and wild-type mice [1].
  • The vasopressin 1b receptor (Avpr1b) is one of two principal receptors mediating the behavioral effects of vasopressin (Avp) in the brain [14].
  • From all OT and VP receptors, only OTR was expressed by all T-cell subsets, while V1bR was found in double positive and single positive CD8 cells [10].
