Islet-activating protein inhibits leukotriene D4- and leukotriene C4- but not bradykinin- or calcium ionophore-induced prostacyclin synthesis in bovine endothelial cells.

Figures 1a and 1b show the tissue and plasma biosynthetic pathway of bradykinin

The gene of the bradykinin does not exist: it is the product of a post-transcriptional edit and post-translational modifications performed by various enzymes.
The first step is the transcription of the gene ()found on chromosome 3q27.


Bradykinin is also thought to be the cause of the dry ..

Bradykinins are a family of short, structurally similar peptides that activate sensory fibres, contract venous smooth muscle, stimulate release of cytokines, induce connective tissue proliferation and mediate endothelium-dependent vasodilation [, ]. Bradykinin antagonists are used in the treatment of inflammation, asthma, mild pain and endotoxic shock.

As the image above shows, the bradykinin has an important role in pro-inflammatory response.
Recent studies demonstrate the bradykinin induces expression in airway smooth muscles cells by involving the activation of .

Bradykinin - an overview | ScienceDirect Topics

The action of bradykinin could be mimicked by 1-oleoyl-2-acetyl-glycerol, an analogue of diacylglycerol (DAG), and by RHC80267, a DAG-lipase inhibitor.

All mammalian cells except erythrocytes synthesize eicosanoids

The bradykinin is a nonapeptide; yet it cohoperates with such a huge amount of pathways they are still to be completely understood.
In the kinin system there are two receptors (GPCRs) whose principal ligand is the protein bradykinin; they are known as and (Bradykinin Receptor 1 and 2, respectively).
While B2 is constitutively expressed in many tissues, B1 is thought to be induced under inflammatory conditions; however B1 and B2 receptors are always expressed in the hippocampus of humans and seem to be overexprssed in people with temporal lobe epilepsy

ACE is the most important enzyme for the inactivation of Bradykinin due to the turn-over plot.
In fact, once produced bradykinin rapidly decreases its blood concentration while a big rise of 1-5 bradykinin peptide performed by is seen.
As shown below, activity is performed twice as it firstly cleaves the bradykinin so that a 1-7 bradykinin is produced; as soon as this process is completed it performes its last activity by cutting this peptide and giving the 1-5 bradykinin.
