Main Results:

  • Confirmed the existence of B1 and B2 bradykinin receptor subtypes.
  • Identified distinct roles for B2 receptors in acute inflammation and B1 receptors in chronic inflammation.
  • Molecular cloning revealed sequence homology and potential species homologues.

Conclusions:

  • Bradykinin B2 receptors are implicated in acute inflammatory events like edema and pain.
  • Bradykinin B1 receptors are involved in chronic inflammatory responses and hyperalgesia.
  • Further research on bradykinin receptors will facilitate the rational design of novel anti-inflammatory therapeutics.
