Bradykinin receptor B1 (BDKRB1) is a G protein-coupled receptor (GPCR) primarily activated by des-Arg9-bradykinin and des-Arg10-kallidin, metabolites of kinin peptides. Unlike its constitutively expressed counterpart BDKRB2. BDKRB1 is minimally present under normal physiological conditions but is markedly upregulated during inflammation, tissue injury, or exposure to cytokines (e.g., IL-1β, TNF-α). This inducible expression suggests its role in pathophysiological processes, including chronic pain, vascular permeability, hyperalgesia, and immune modulation.
BDKRB1 signaling involves Gq/11 protein activation, triggering intracellular pathways like phospholipase C (PLC)-mediated calcium mobilization, protein kinase C (PKC), and mitogen-activated protein kinase (MAPK) cascades. These pathways amplify inflammatory responses and sensitize nociceptive neurons. The receptor is implicated in chronic inflammatory diseases (e.g., arthritis), neuropathic pain, diabetes-associated complications, and cancer progression.
Recombinant human BDKRB1. produced via heterologous expression systems (e.g., HEK293 cells), enables structural and functional studies. Research focuses on its ligand-binding dynamics, receptor dimerization, and interactions with regulatory proteins. Pharmacological targeting of BDKRB1 with antagonists has therapeutic potential, though clinical efficacy remains under investigation. Its context-dependent regulation and crosstalk with other inflammatory mediators underscore its complexity in disease mechanisms and therapeutic strategies.
