bradykinin \bra`dy*ki"nin\ n.
a hypotensive tissue hormone ( C50H73N15O11) which acts on
smooth muscle, dilates peripheral vessels and increases
capillary permeability. It is formed locally in injured
tissue and is believed to play a role in the inflammatory
process. It is a nonapeptide with the sequence:
Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg.
--MI11
Syn: kallidin I; callidin I; kallidin-9.
Wiktionary
n. (context biochemistry English) One of the kinins, a nonapeptide that reduces blood pressure by dilate blood vessels.
Wikipedia
Bradykinin is an inflammatory mediator. It is a peptide that causes blood vessels to dilate (enlarge), and therefore causes blood pressure to fall. A class of drugs called ACE inhibitors, which are used to lower blood pressure, increase bradykinin (by inhibiting its degradation) further lowering blood pressure. Bradykinin dilates blood vessels via the release of prostacyclin, nitric oxide, and Endothelium-Derived Hyperpolarizing Factor.
Bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
Usage examples of "bradykinin".
Eventually, bradykinin, kallidin, and all similar hormones were grouped under the name kinins.
Or maybe you could build in mechanisms to break down the excess bradykinin almost immediately.
It comes packaged with a special agent—a bradykinin agonist called 'Neurolax'—which increases the permeability of the blood-brain barrier by activating B2 receptors on the endothelial cells of the brain's capillaries.
