Disease relevance of Cnr2

 

Psychiatry related information on Cnr2

  • This multifocal expression of CB2 immunoreactivity in brain suggests that CB2 receptors may play broader roles in the brain than previously anticipated and may be exploited as new targets in the treatment of depression and substance abuse [6].

Anatomical context of Cnr2

  • Mice with a targeted deletion of either the cannabinoid receptor type 1 (Cnr1) or type 2 (Cnr2) gene show an alteration of bone mass, and pharmacological modification of both receptors can regulate osteoclast activity and BMD [18].
  • CB2 is expressed in osteoblasts, osteocytes, and osteoclasts [14].
  • A CB2-specific agonist that does not have any psychotropic effects enhances endocortical osteoblast number and activity and restrains trabecular osteoclastogenesis, apparently by inhibiting proliferation of osteoclast precursors and receptor activator of NF-kappaB ligand expression in bone marrow-derived osteoblasts/stromal cells [14].
  • In line with this, we found that Langerhans cells (MHC class II(+)) contain a substantial amount of CB2 receptor mRNA, whereas keratinocytes (MHC class II(-)) do not [3].
  • This compound was equipotent to anandamide in competing with [3H]CP55,940 binding to plasma membranes prepared from L cells expressing the human CB1 receptor and from ATt-20 cells expressing the human CB2 receptor [19].
