In addition to the classical notion of the KKS as a potent vasodilator and a mediator of inflammatory responses, recent studies suggest a link between the KKS and oxidative stress. The acquired immunity proceeds via specific recognition. Most striking observations in COVID-19 patients are the hints on pulmonary edema (also seen on CT scans as ground glass opacities), dry cough, fluid restrictions to prevent more severe hypoxia, the huge PEEP that is needed while lungs are compliant, and the fact that anti-inflammatory therapies are not powerful enough to counter the severity.

Abstract. The kallikrein/kinin system (KKS) constitutes a peptide cascade that is important in cardiovascular and renal regulation [1121,1122]. Kinins, released during sepsis, induce vascular leakage and vasodilation. In humans, plasma kallikrein forms bradykinin from HMWK, whereas tissue kallikrein forms kallidin from HMWK and LMWK (Figs 2 and 3). These short-lived peptides, including bradykinin, kallidin and T-kinin, are generated during tissue injury and noxious stimulation.

Histamine is chemically classified as an amine, an organic molecule based on the structure of ammonia (NH 3). Neurokinin A (formally known as substance K) is a member of the tachykinin family of neuropeptide neurotransmitters. Inhibition of that enzyme attenuates kinin degradation and potentiates the action of kinins in many pharmacological investigations. decreased loss of plasma protein and fluid. The long-standing appreciation of their diverse pharmacological properties and biochemical characteristics is being supplemented by modern definitions of their cellular receptors' signal-transduction mechanisms and physiological and pathological roles. 1.

Inflammation (from Latin: inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, [1] [2] and is a protective response involving immune cells, blood vessels, and molecular mediators. The coagulation cascade is discussed in Chapters 10 and 20; the kinin and complement systems are presented here. Kinins are proteins in the blood that cause inflammation and affect blood pressure (especially low blood pressure). My Bio. This is the traditional way of describing the plasma kinin-forming cascade which originated when addition of blood to a glass tube was found to initiate blood coagulation, and simultaneously, release of the nonapeptide, bradykinin (arg pro pro gly phe ser pro phe arg). Speculations about the role of kallikreins and kinins in hemodynamic, excretory, and metabolic processes originated in 1909 when the hypotensive property of human urine, now known to represent excreted renal kallikrein, was discovered. However, due to their metabolic characteristics, these peptides act mainly as an autocrine/paracrine factor to locally regulate blood perfusion of organs. B) histamine.
