Application

[Lys-des-Arg9]-Bradykinin has been used as a B1R agonist to investigate the role of B1R in diabetes-induced secondary hemorrhage.

Biochem/physiol Actions

[Des-Arg10]-kallidin or [Lys-des-Arg9]-Bradykinin is a bradykinin B1 receptor agonist. It strongly upregulates the B1 receptor and is blocked by a specific protein kinase C inhibitor. The upregulation is correlated with the induction of transcription nuclear factor κB (NF-κB). Elevation of Lys-des[Arg9]–bradykinin because of airway inflammation in asthma patients is known to modify the immune responses. It affects the migration and production of interleukin-12 in monocyte-derived dendritic cells.

The bradykinin B1-receptor is strongly upregulated under chronic inflammatory conditions. However, the mechanism and reason are not known. Because a better understanding of the mechanism of the upregulation will help in understanding its potential importance in inflammation, we have studied

In the kallikrein-kinin and renin-angiotensin systems the main receptors, B1 and B2 (kinin receptors) and AT1 and AT2 (angiotensin receptors) respectively, are seven-transmembrane domain G-protein-coupled receptors. Considering that the B1 agonists Des-Arg9-BK (Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe), Lys-desArg9-BK or Des-Arg10-KD (Lys-Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe) and the AT1

Responses to kallidin, des-Arg9-bradykinin (DABK), and des-Arg10-kallidin (DAK) were investigated in the hindlimb vascular bed of the cat under constant-flow conditions. Injections of kallidin, DABK, and DAK into the hindlimb perfusion circuit produced dose-dependent vasodilator responses in the hindlimb vascular

The authors previously discovered that genes for the bradykinin-1 (B1) receptor and the transient receptor potential vanilloid subtype 1 (TRPV1) were overexpressed in animals exhibiting thermal hyperalgesia (TH) following spinal cord injury (SCI). They now report the effect of TRPV1

Bradykinin B1 and B2 receptors contribute to nociceptor sensitization under inflammatory conditions. Here, we examined the vascular inflammatory responses and nociceptive effects resulting from activation of B1 and B2 receptors in healthy and UV-B irradiated skin in human volunteers. The
