what do b1 receptors do
1 The transcriptional activity of the B1 receptor for kinins increased in patients with grade 1 and grade 2 endometrial cancer when compared to the control group, whereas it decreased in patients with grade 3 endometrial cancer. Kinin B1 receptor homo-oligomerization is required for receptor trafficking to the cell surface. 2  Bradykinin B1 receptor is induced in inflammatory diseases and contributes to hyperthermia through a vagal sensory mechanism.
