Kinin B1 receptor modulates glucose homeostasis and physical exercise capacity by altering adrenal catecholamine synthesis and secretion. Mol Cell Endocrinol 2024; 579:112085.

Abstract
Our group has shown in several papers that kinin B1 receptor (B1R) is involved in metabolic adaptations, mediating glucose homeostasis and interfering in leptin and insulin signaling. Since catecholamines are involved with metabolism management, we sought to evaluate B1R role in catecholamine synthesis/secretion. Using B1R global knockout mice, we observed increased basal epinephrine content, accompanied by decreased hepatic glycogen content and increased glucosuria. When these mice were challenged with maximal intensity exercise, they showed decreased epinephrine and norepinephrine response, accompanied by disturbed glycemic responses to effort and poor performance. This phenotype was related to alterations in adrenal catecholamine synthesis: increased basal epinephrine concentration and reduced norepinephrine content in response to exercise, as well decreased gene expression and protein content of tyrosine hydroxylase and decreased gene expression of dopamine beta hydroxylase and kinin B2 receptor. We conclude that the global absence of B1R impairs catecholamine synthesis, interfering with glucose metabolism at rest and during maximal exercise.

Abstract
Antihypertensive pharmacological treatments focus on the use of angiotensin-converting enzyme (ACE) inhibitors, AT1 receptor antagonists, and beta-blockers as single and combined treatments. The effect of single treatments on the mRNA expression of some components of the renin-angiotensin system has been studied, but not the effect of combined treatments. This study determined the expression of the AT1, AT2, B1, and B2 receptors and of the enzymes ACE and ACE2 in hypertensive rats treated with captopril-propranolol or losartan-propranolol. Methods: The mRNA expression of the receptors and enzymes was determined by reverse transcription-quantitative polymerase chain reaction in the aorta of spontaneously hypertensive rats under different treatments. Results: Rats under combined treatments showed a decrease in the expression of AT1 and ACE, and an increase in the expression of the B1 receptor (captopril + propranolol group: 0.43 ± 0.046, 2.243 ± 0.269, 3.356 ± 0.418; Group: losartan + propranolol: 0.727 ± 0.071, 0.852 ± 0.102, 1.277 ± 0.131 compared to the spontaneously hypertensive group: 1 ± 0.212, 1 ± 0.192, 1 ± 0.214). This decrease in the expression of ACE and AT1 suggests a reduction in the expression of Ang II that could be related to a lower response to this vasoconstrictor. An increase in the expression of B1 would improve vasodilation, which would be a beneficial effect of combined therapies for hypertension.

Abstract
Kinins are the endogenous ligands of the constitutive B2 receptor (B2R) and the inducible B1 receptor (B1R). Whereas B2R prevents insulin resistance, B1R is involved in insulin resistance and metabolic syndrome. However, the contribution of B1R in type 2 diabetes associated with obesity remains uncertain. The aim of the present study was to examine the impact of 1-week treatment with a selective B1R antagonist (SSR240612, 10 mg/kg per day, by gavage) on hyperglycemia, hyperinsulinemia, leptinemia, body mass gain, and abnormal plasma fatty acids in obese Zucker diabetic fatty (ZDF) rats. Treatment with SSR240612 abolished the body mass gain and reduced polyphagia, polydipsia, and plasma fatty acid alterations in ZDF rats without affecting hyperglycemia, hyperinsulinemia, and hyperleptinemia. The present study suggests that the upregulated B1R plays a role in body mass gain and circulating fatty acid alterations in ZDF rats. However, mechanisms other than B1R induction would be implicated in glucose metabolism disorder in ZDF rats, based on the finding that SSR240612 did not reverse hyperglycemia and hyperinsulinemia.

Abstract
The kallikrein-kinin and renin-angiotensin systems interact at multiple levels. In the present study, we tested the hypothesis that the B1 kinin receptor (B1R) contributes to vascular hypertrophy in angiotensin II (ANG II)-induced hypertension, through a mechanism involving reactive oxygen species (ROS) generation and extracellular signal-regulated kinase (ERK1/2) activation. Male Wistar rats were infused with vehicle (control rats), 400 ng/Kg/min ANG II (ANG II rats) or 400 ng/Kg/min ANG II plus B1 receptor antagonist, 350 ng/Kg/min des-Arg(9)-Leu(8)-bradykinin (ANGII+DAL rats), via osmotic mini-pumps (14 days) or received ANG II plus losartan (10 mg/Kg, 14 days, gavage - ANG II+LOS rats). After 14 days, ANG II rats exhibited increased systolic arterial pressure [(mmHg) 184 ± 5.9 vs 115 ± 2.3], aortic hypertrophy; increased ROS generation [2-hydroxyethidium/dihydroethidium (EOH/DHE): 21.8 ± 2.7 vs 6.0 ± 1.8] and ERK1/2 phosphorylation (% of control: 218.3 ± 29.4 vs 100 ± 0.25]. B1R expression was increased in aortas from ANG II and ANG II+DAL rats than in aortas from the ANG II+LOS and control groups. B1R antagonism reduced aorta hypertrophy, prevented ROS generation (EOH/DHE: 9.17 ± 3.1) and ERK1/2 phosphorylation (137 ± 20.7%) in ANG II rats. Cultured aortic vascular smooth muscle cells (VSMC) stimulated with low concentrations (0.1 nM) of ANG II plus B1R agonist exhibited increased ROS generation, ERK1/2 phosphorylation, proliferating-cell nuclear antigen expression and [H3]leucine incorporation. At this concentration, neither ANG II nor the B1R agonist produced any effects when tested individually. The ANG II/B1R agonist synergism was inhibited by losartan (AT1 blocker, 10 µM), B1R antagonist (10 µM) and Tiron (superoxide anion scavenger, 10 mM). These data suggest that B1R activation contributes to ANG II-induced aortic hypertrophy. This is associated with activation of redox-regulated ERK1/2 pathway that controls aortic smooth muscle cells growth. Our findings highlight an important cross-talk between the DABK and ANG II in the vascular system and contribute to a better understanding of the mechanisms involved in vascular remodeling in hypertension.

Evidence that kinin B2 receptor expression is upregulated by endothelial overexpression of B1 receptors. Peptides 2013; 42:1-7.

Abstract
Bradykinin (BK) and des-Arg(9)-bradykinin (DBK) of kallikrein-kinin system exert its effects mediated by the B2 (B2R) and B1 (B1R) receptors, respectively. It was already shown that the deletion of kinin B1R or of B2R induces upregulation of the remaining receptor subtype. However studies on overexpression of B1R or B2R in transgenic animals have supported the importance of the overexpressed receptor but the expression of another receptor subtype has not been determined. Previous study described a marked vasodilatation and increased susceptibility to endotoxic shock which was associated with increased mortality in response to DBK in thoracic aorta from transgenic rat overexpressing the kinin B1R (TGR(Tie2B1)) exclusively in the endothelium. In another study, mice overexpressing B1R in multiple tissues were shown to present high susceptibility to inflammation and to lipopolysaccharide-induced endotoxic shock. Therefore the role of B2R was investigated in the thoracic aorta isolated from TGR(Tie2B1) rats overexpressing the B1R exclusively in the vascular endothelium. Our findings provided evidence for highly increased expression level of the B2R in the transgenic rats. It was reported that under endotoxic shock, these rats exhibited exaggerated hypotension, bradycardia and mortality. It can be suggested that the high mortality during the pathogenesis of endotoxic shock provoked in the transgenic TGR(Tie2B1) rats could be due to the enhanced expression of B2R associated with the overexpression of the B1R.

Abstract
Nitrogranulogen (NTG) may modify the character of inflammatory reactions. These modifications are a result of cytotoxic and mutagenic effects. NTG has high affinity to DNA and causes disorders in the synthesis of acute phase proteins (e.g., haptoglobin, transferrin, fibrinogen, and complement protein C3). Our previous studies have shown that small doses of NTG can enhance immunological defense reactions in the organism. The aim of the current studies was to determine how different NTG doses cause changes in the values of biochemical parameters in pleuritis-induced rats. The animals were randomized into five groups: Group I - control group; Group II - IP (induced pleuritis) group; Group III - NTG5 group; Group IV - NTG50 group; Group V - NTG600 group. Blood was collected from all groups of animals at 24, 48, and 72 h after the initiation of the carrageenin-induced inflammatory reaction. These investigations revealed that a dose of 5 μg NTG/kg b.w. (body weight) can change the character of the inflammation. Our studies also show that a dose of 600 μg NTG/kg b.w. causes a rapid decrease in the level of C3 at the 72 h of the experiment (after 3 applications every 24 h), which indicates a cytotoxic action of such a large NTG dose. NTG used at doses of 50 and 600 μg/kg b.w. causes the opposite metabolism of albumins and other serum proteins. Our studies show that the different doses of NTG have distinct effects on the inflammatory reaction.

Kinin B1 receptor enhances the oxidative stress in a rat model of insulin resistance: outcome in hypertension, allodynia and metabolic complications. PLoS One 2010; 5:e12622.

Abstract
Background Kinin B1 receptor (B1R) is induced by the oxidative stress in models of diabetes mellitus. This study aims at determining whether B1R activation could perpetuate the oxidative stress which leads to diabetic complications. Methods and Findings Young Sprague-Dawley rats were fed with 10% D-Glucose or tap water (controls) for 8–12 weeks. A selective B1R antagonist (SSR240612) was administered acutely (3–30 mg/kg) or daily for a period of 7 days (10 mg/kg) and the impact was measured on systolic blood pressure, allodynia, protein and/or mRNA B1R expression, aortic superoxide anion (O2•−) production and expression of superoxide dismutase (MnSOD) and catalase. SSR240612 reduced dose-dependently (3–30 mg/kg) high blood pressure in 12-week glucose-fed rats, but had no effect in controls. Eight-week glucose-fed rats exhibited insulin resistance (HOMA index), hypertension, tactile and cold allodynia and significant increases of plasma levels of glucose and insulin. This was associated with higher aortic levels of O2•−, NADPH oxidase activity, MnSOD and catalase expression. All these abnormalities including B1R overexpression (spinal cord, aorta, liver and gastrocnemius muscle) were normalized by the prolonged treatment with SSR240612. The production of O2•− in the aorta of glucose-fed rats was also measured in the presence and absence of inhibitors (10–100 µM) of NADPH oxidase (apocynin), xanthine oxidase (allopurinol) or nitric oxide synthase (L-NAME) with and without Sar[D-Phe8]des-Arg9-BK (20 µM; B1R agonist). Data show that the greater aortic O2•− production induced by the B1R agonist was blocked only by apocynin. Conclusions Activation of kinin B1R increased O2•− through the activation of NADPH oxidase in the vasculature. Prolonged blockade of B1R restored cardiovascular, sensory and metabolic abnormalities by reducing oxidative stress and B1R gene expression in this model.
