Kinin
 | This article may be too technical for most readers to understand. (July 2017) |
A kinin is any of various structurally related polypeptides, such as bradykinin and kallidin.[1] They are members of the autacoid family.[2]
They act locally to induce vasodilation and contraction of smooth muscle.[3] Kinins function as mediators for inflammatory responses by triggering the immune system. They are also able to regulate cardiovascular and renal function through mediating the effects of ACE inhibitors.[4]
It is a component of the kinin-kallikrein system.
Their precursors are kininogens.[5]
In botany, the plant hormones known as cytokinins were first called kinins, but the name was changed to avoid confusion.[6]
Aspirin inhibits the activation of kallenogen by interfering with the formation of kallikrein enzyme which is essential in the process of activation.
