[PMID: 36853509 PMCID: PMC10366306 DOI: 10.1007/s00403-023-02564-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 12/05/2022] [Accepted: 02/01/2023] [Indexed: 03/01/2023]
Abstract
Acute infectious urticaria, a subset of acute urticaria, with severe persistence wheals and systemic symptoms, response well to corticosteroids treatment in combination with antibiotics. The exact pathogenic mechanisms are not fully understood. In this study, we aim to analyze the different clinical features, compare the level of neutrophil activation, and investigate the expression of inflammatory related cytokine in patients with acute urticaria and acute infectious urticaria. Eighteen patients with acute infectious urticaria and eighteen patients with acute urticaria were included in this study. We analyzed the difference between the clinical features and the serum expressions of pro-inflammatory factors in the two groups, then examined the levels of inflammation-associated cytokines before and after treatment of acute infectious urticaria. Hematoxylin & eosin (HE) staining and immunohistochemistry (IHC) were used to further study the relationship between neutrophil and neutrophil-derived Myeloperoxidase (MPO) of lesions in the two groups. The expression levels of C-reactive protein (CRP), D-dimer, interleukin 6 (IL-6), IL-8 and chemokine ligand 8 (CCL8) in serum were significantly higher in acute infectious urticaria than acute urticaria. In acute infectious urticaria, the serum expression levels of CCL8 were significantly decreased after the treatment, a significant correlation observed between CRP levels and IL-6, both CCL8 and CRP were positively correlated with neutrophil granulocytes. Neutrophils infiltration were not observed by HE stains in two groups, but in IHC stains we found a positive expression of MPO in acute infectious urticaria lesions. Elevated neutrophil in the serum, which is associated with the levels of IL-8 & CCL8, and positively expressed MPO in lesions, may be involved in the pathogenic mechanism of acute infectious urticaria.

Punicalagin protects against the development of pancreatic injury and insulitis in rats with induced T1DM by reducing inflammation and oxidative stress. Mol Cell Biochem 2022; 477:2817-2828.

Abstract
Pancreatic inflammation and oxidative damage remain major concerns in type 1 diabetes mellitus (T1DM). Punicalagin, a major polyphenol in pomegranates, exhibited antioxidant and protective effects on several organs in case of T1DM; however, no study has yet explored the protective effects of punicalagin on the pancreas and islets of Langerhans. T1DM was induced by injecting 40 mg/kg streptozotocin (STZ) intraperitoneally. Punicalagin (1 mg/kg ip) was injected daily for 15 days after T1DM induction. In diabetic rats, punicalagin treatment lowered the levels of inflammatory biomarkers (monocyte chemoattractant protein-1 and C-reactive protein) and adhesion molecules (E-selectin, intercellular adhesion molecule, and vascular cell adhesion molecule) while activating myeloperoxidase activity. Treatment of diabetic rats with punicalagin improved glutathione content and superoxide dismutase, catalase, and glutathione peroxidase activities; upregulated serum paraoxonase-1 activity; and prevented the elevation lipid peroxidation and protein oxidation products in the pancreas. Furthermore, punicalagin protected the pancreas against STZ-induced histopathological alterations and increased immune-reactive β-cells while reducing leucocyte infiltration into the islets of Langerhans, leading to normalized blood glucose and insulin levels. These findings indicated that punicalagin might protect against the development of insulitis in T1DM. In conclusion, punicalagin exerts a strong protective effect on the pancreas against oxidative injury and inflammation in STZ-induced experimental T1DM. The present results recommend punicalagin as a potential adjuvant for reducing diabetes-associated insulitis.

Adenosine A 2A receptor and vascular response: role of soluble epoxide hydrolase, adenosine A 1 receptor and angiotensin-II. Mol Cell Biochem 2021; 476:1965-1978.

Abstract
Previously, we have reported that the coronary reactive hyperemic response was reduced in adenosine A2A receptor-null (A2AAR-/-) mice, and it was reversed by the soluble epoxide hydrolase (sEH) inhibitor. However, it is unknown in aortic vascular response, therefore, we hypothesized that A2AAR-gene deletion in mice (A2AAR-/-) affects adenosine-induced vascular response by increase in sEH and adenosine A1 receptor (A1AR) activities. A2AAR-/- mice showed an increase in sEH, AI AR and CYP450-4A protein expression but decrease in CYP450-2C compared to C57Bl/6 mice. NECA (adenosine-analog) and CCPA (adenosine A1 receptor-agonist)-induced dose-dependent vascular response was tested with t-AUCB (sEH-inhibitor) and angiotensin-II (Ang-II) in A2AAR-/- vs. C57Bl/6 mice. In A2AAR-/-, NECA and CCPA-induced increase in dose-dependent vasoconstriction compared to C57Bl/6 mice. However, NECA and CCPA-induced dose-dependent vascular contraction in A2AAR-/- was reduced by t-AUCB with NECA. Similarly, dose-dependent vascular contraction in A2AAR-/- was reduced by t-AUCB with CCPA. In addition, Ang-II enhanced NECA and CCPA-induced dose-dependent vascular contraction in A2AAR-/- with NECA. Similarly, the dose-dependent vascular contraction in A2AAR-/- was also enhanced by Ang-II with CCPA. Further, t-AUCB reduced Ang-II-enhanced NECA and CCPA-induced dose-dependent vascular contraction in A2AAR-/- mice. Our data suggest that the dose-dependent vascular contraction in A2AAR-/- mice depends on increase in sEH, A1AR and CYP4A protein expression.

Abstract
Significance: Myeloperoxidase (MPO) is a heme peroxidase that is primarily expressed by neutrophils. It has the capacity to generate several reactive species, essential for its inherent antimicrobial activity and innate host defense. Dysregulated MPO release, however, can lead to tissue damage, as seen in several diseases. Increased MPO levels in circulation are therefore widely associated with conditions of increased oxidative stress and inflammation. Recent Advances: Several studies have shown a strong correlation between MPO and cardiovascular disease (CVD), through which elevated levels of circulating MPO are linked to poor prognosis with increased risk of CVD-related mortality. Accordingly, circulating MPO is considered a "high-risk" biomarker for patients with acute coronary syndrome, atherosclerosis, heart failure, hypertension, and stroke, thereby implicating MPO as a multifaceted target for cardiovascular protection. Consistently, recent studies that target MPO in animal models of CVD have demonstrated favorable outcomes with regard to disease progression. Critical Issues: Although most of these studies have established a critical link between circulating MPO and worsening cardiac outcomes, the mechanisms by which MPO exerts its detrimental effects in CVD remain unclear. Future Directions: Elucidating the mechanisms by which elevated MPO leads to poor prognosis and, conversely, investigating the beneficial effects of therapeutic MPO inhibition on alleviating disease phenotype will facilitate future MPO-targeted clinical trials for improving CVD-related outcomes.

Abstract
Myeloperoxidase (MPO) is a heme-containing peroxidase expressed mainly in neutrophils and to a lesser degree in monocytes. In the presence of hydrogen peroxide and halides, MPO catalyzes the formation of reactive oxygen intermediates, including hypochlorous acid (HOCl). The MPO/HOCl system plays an important role in microbial killing by neutrophils. In addition, MPO has been demonstrated to be a local mediator of tissue damage and the resulting inflammation in various inflammatory diseases. These findings have implicated MPO as an important therapeutic target in the treatment of inflammatory conditions. In contrast to its injurious effects at sites of inflammation, recent studies using animal models of various inflammatory diseases have demonstrated that MPO deficiency results in the exaggeration of inflammatory response, and that it affects neutrophil functions including cytokine production. Given these diverse effects, a growing interest has emerged in the role of this well-studied enzyme in health and disease.

A positive correlation between myeloperoxidase-generated HOCl level and oxidative status in STZ-diabetic rats. Talanta 2017; 170:119-127. [PMID: 28501147 DOI: 10.1016/j.talanta.2017.03.102] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 03/27/2017] [Accepted: 03/29/2017] [Indexed: 01/23/2023]
Abstract
Myeloperoxidase (MPO) is a key enzyme derived from leukocytes which is associated with the initiation and progression of many inflammatory diseases. Increased levels of MPO may contribute to cellular dysfunction and tissues injury by producing highly reactive oxidants such as hypochlorous acid (HOCl). Myeloperoxidase-generated HOCl is therefore considered as a relevant biomarker of oxidative stress-related damage and its quantitation is of great importance to the study of disease progression. In this context, the current study describes a rapid, sensitive and homogeneous fluorescence-based method for detecting the MPO chlorination activity in biological samples. This assay utilizes 7-hydroxy-2-oxo-2H-chromene-8-carbaldehyde oxime as a selective probe for HOCl detection, and is adapted to 96-well microplates to allow high-throughput quantitation of active MPO. The ability of the method to monitor HOCl release was further investigated in hyperglycemic streptozotocin-treated diabetic rats. The data proved that the present assay has a reliable performance when quantitating the active MPO in the plasma of diabetic animals, a feature of inflammatory disease found concomitant with an elevation of protein carbonyls levels and lipid peroxidation and which was negatively correlated with the ratio of reduced-to-oxidized glutathione.

Abstract
Cardiovascular complications are one of the major factors for early mortality in the present
worldwide scenario and have become a major challenge in both developing and developed nations. It
has thus become of immense importance to look for different therapeutic possibilities and treatments
for the growing burden of cardiovascular diseases. Recent advancements in research have opened
various means for better understanding of the complication and treatment of the disease. Adenosine
receptors have become tool of choice in understanding the signaling mechanism which might lead to
the cardiovascular complications. Adenosine A3 receptor is one of the important receptor which is extensively studied as a
therapeutic target in cardiovascular disorder. Recent studies have shown that A3AR is involved in the amelioration of cardiovascular
complications by altering the expression of A3AR. This review focuses towards the therapeutic potential of
A3AR involved in cardiovascular disease and it might help in better understanding of mechanism by which this receptor
may prove useful in improving the complications arising due to various cardiovascular diseases. Understanding of A3AR
signaling may also help to develop newer agonists and antagonists which might be prove helpful in the treatment of cardiovascular
disorder.
