Any of a group of substances formed in body tissue in response to injury. They are polypeptides and cause vasodilation and smooth muscle contraction.
- ‘In addition, the release of vasoactive kinins from muscle may interfere with renal hemodynamics.’
- ‘Three different pathways may lead to kinin formation during inflammation: the generation of bradykinin as a result of activation of the Hageman factor and the production of plasma kallikrein; the production of lysylbradykinin by tissue kallikreins; and the action of cellular proteases in kinin formation.’
- ‘The classic pathways of complement and kinins are activated and attract the inflamed cells.’
- ‘During states of ineffective arterial volume, local production of vasodilatory prostanoids and kinins in the kidney offsets the decrease in renal blood flow and helps maintain the glomerular filtration rate.’
- ‘This same converting enzyme also breaks down kinins, which are powerful vasodilators, and therefore tend to lower the blood pressure.’
A compound that promotes cell division and inhibits aging in plants.Also called cytokinin
- ‘Maybe these cells would differ in sensitivity to auxin or kinin.’
- ‘Coconut milk is recognized as a rich source of plant cell division inducers, which have become known as kinins.’
- ‘Other topical therapies new to the anti-aging scene include plant kinins which appear to have both anti-irritant and photoaging reversal properties with no perceived irritation.’
1950s: from Greek kinein to move + -in.
