At their core, kinin peptides are defined by their biological activity.作者：TE Ruud·1985·被引用次数：35—Activation of the plasma kallikrein-kininsystem in peritoneal exudate during acute experimentalpancreatitisappears to be of importance for the initial ... They are essentially short chains of amino acids that, upon interaction with specific receptors, can elicit a cascade of biological responses. The most well-characterized kinin peptides include bradykinin and kallidin. Bradykinin and kallidin are endogenous kinin peptide hormones that belong to the kallikrein–kinin system and are essential to the regulation of blood pressure, among other functions. In humans, the kinin peptide system is remarkably complex. While plasma kallikrein generates bradykinin peptides, a different enzyme, glandular kallikrein, is responsible for generating kallidin peptides.

The physiological functions attributed to kinin peptides are diverse.Towards understanding the kallikrein-kinin system Research indicates that they have a diverse array of biological activities, including promoting the endothelial release of nitric oxide, influencing natriuresis and diuresis, and offering cardioprotective effects. Furthermore, kinins are involved in the modulation of blood flow and vascular permeability作者：FW Nugent·1969·被引用次数：11—Well-known pharmacolog- ic actions ofkininsinclude pain production, vasodilatation, increased vascular permeabili- ty, hypotension, smooth muscle stimulation,.. One of the key mechanisms through which kinin peptides exert their effects is by binding to specific receptors, primarily the B1R and B2RThe Pathogenesis of Chronic Pancreatitis. These receptors, located on cell surfaces, act as molecular switches, initiating intracellular signaling pathways. For instance, certain kinin peptides themselves can activate the kinin receptors B1R and B2R.The Pathogenesis of Chronic Pancreatitis Bradykinin (BK) is a peptide that promotes inflammation; it achieves this by causing arterioles to dilate (enlarge) through the release of prostacyclin and nitric oxide.

Beyond their normal physiological roles, kinin peptides are implicated in various pathological states. The kallikrein-kinin system has been extensively studied in the context of acute pancreatitis.The incidence of acute pancreatitis with GLP-1 receptor agonist therapy ... During an episode of acute pancreatitis, the activity of the KKS can be significantly altered. Studies have shown that kinins are generated by t-KK (tissue kallikrein) and subsequently activate kinin B2 receptors to increase vascular permeability within the pancreas. This heightened activity can contribute to the inflammatory cascade and microcirculatory disturbances characteristic of the disease. Evidence suggests that kinin activation and protease inhibitory activity were closely correlated with the severity and clinical course of pancreatitisKallikrein-Kinin System in Acute Pancreatitis. In some instances, total kininogen levels were very low in the pancreas of controls, but increased 75-fold during acute pancreatitis, highlighting a significant shift in KKS activity during this condition.Studies on the Plasma Kallikrein-Kinin System in ... The involvement of the kallikrein-kinin system in acute pancreatitis is further supported by studies demonstrating that blocking kinin receptors can suppress the inflammatory response.作者：FW Nugent·1969·被引用次数：11—Well-known pharmacolog- ic actions ofkininsinclude pain production, vasodilatation, increased vascular permeabili- ty, hypotension, smooth muscle stimulation,. This has led to investigations into the potential of B2-bradykinin antagonists and kallikrein inhibitors as therapeutic strategies for pancreatitis. The study and comparison of the kallikrein-kinin system in patients with chronic pancreatitis compared to those with comorbidities also reveals complex interplay and potential disbalancesTowards understanding the kallikrein-kinin system.

The localization of kinin peptides is also noteworthy. Research has indicated that the levels of kinin peptides in tissues are generally higher than those found in the blood, supporting the idea that the kallikrein-kinin system primarily operates within tissues. This tissue-specific action is important for understanding their localized effects, such as in modulating inflammatory responses or contributing to pain perceptionBradykinin and kallidin are endogenous kinin peptide hormonesthat belong to the kallikrein–kinin system and are essential to the regulation of blood pressure, ....
