Cheng JH, Li J, Sun DW. In vivo biological analysis of cold plasma on allergenicity reduction of tropomyosin in shrimp. Food Chem 2024; 432:137210. [PMID: 37659333 DOI: 10.1016/j.foodchem.2023.137210] [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: 04/13/2023] [Revised: 08/02/2023] [Accepted: 08/17/2023] [Indexed: 09/04/2023]
Abstract
In vivo biological regulations of the allergenicity of tropomyosin (TM) treated by cold plasma (CP) were investigated by in vivo mouse model. The sensitization models of Balb/c mice were successfully established. CP treatment reduced the allergic symptoms of mice and regulated the Th1/Th2 balance to prevent allergy by activating Treg cells, which was deduced by serum and cytokines analysis. For intestinal flora analysis, allergy occurrence was accompanied by the decreased species abundance and the increased species diversity of intestinal flora. The significant species composition difference between the TM group and the PBS group showed a possible connection between bacterial diversity and allergy. Furthermore, Firmicutes, Bacteroidetes, Parabacteroides, Alloprevotella, Bacteroides, and Lachnospiraceae could relate to allergy occurrence. Intestinal section analysis suggested that allergy occurrence was accompanied by the damaged intestinal structure, and CP treatment could relieve the damage caused by an allergy.

Abstract
The pathogenesis of Androctonus autralis hector (Aah) scorpion venom involved cellular and molecular mechanisms resulting in multi-organ dysfunction. However, little is reported about the effects of venom on the gastrointestinal axis. Mast cells (MCs) are known to play a crucial role in modulating immune response of the gut. This study aims to investigate the involvement of this cell type in venom-induced gastric and intestinal disorders in a time course (3 and 24h). The obtained results revealed that Aah scorpion venom induced inflammatory cell infiltration as shown by the increase of the myeloperoxidase and eosinophil peroxidase activities. Overexpression of the c-kit receptor (CD117) severely imbalanced the redox status with depletion of antioxidant systemic accompanied by gastrointestinal tissue damage. Moreover, an increased level of lactate dehydrogenase in the serum was correlated with tissue injuries. Pharmacological inhibition of MCs targeting tyrosine kinase (TK) reduces the generation of reactive oxygen species and normalizes catalase, and gluthation S-transferase activities to their physiological levels. In addition, histopathological alterations were restored after pretreatment with c-kit receptor inhibitor associated with a considerable reduction of MC density. Interestingly, obtained results indicate that MCs might be involved in gastric modulation and intestinal inflammation through c-kit signaling following sub-cutaneous Aah venom injection.

Abstract
In Algeria, Androctonus australis hector scorpion envenomation remains a major problem of public health because of non-efficient therapy. The development of safe vaccine against scorpion venom could be one key strategy for the envenomation prevention. The irradiation of venom by γ-rays develops suitable immunogens which produced effective antivenom and safe vaccine. In this study, we investigated the ability of the irradiated toxic fraction (γ-FtoxG50) to induce long-term memory humoral response in immunized animals (mice and rabbits), by involving the long-lived plasma cells to prevent efficiently the lethality of scorpion envenomation. For this purpose, an appropriate immunization schedule was established in mice and rabbits using three (3) similar doses of γ-FtoxG50 associated with Alum adjuvant. Obtained results indicate that the long-term immunogenicity of γ-FtoxG50 is able to induce the long-term memory humoral response with a high level of specific antibodies. The long-term persistence of antibody levels could depend on bone marrow memory plasma cells. These cells produce continuously antibodies without antigen stimulus. Furthermore, an enhanced memory response was obtained post-repeated envenomation with toxic native venom that leads to improved protection of animals. Together, pre-existing protective antibodies and the activation of memory B-cells could induce a rapid neutralization of scorpion toxins and long-term protection against scorpion envenomation.

Abstract
Systemic inflammatory response and generation of oxidative stress are known to contribute to scorpion venom-induced tissue damage. TLR receptors might represent a link between oxidative stress and inflammation; we therefore investigated whether or not TLR4 is involved in venom-induced immunopathology. The obtained results showed that pharmacological targeting of TLR4 with the selective inhibitor TAK-242 (Resatorvid) prevents the inflammatory response induced by subcutaneous administration of Androctonus australis hector (Aah) venom, as revealed by a significant decrease of neutrophil cell count in peripheral blood associated with significant decline of neutrophil degranulation and sequestration to the lung, liver, and kidney tissues. Moreover, TAK-242 administration inhibited nitrite levels increase in serum, malondialdehyde (MDA), and protein carbonyl tissue contents concomitantly with a significant increase of catalase activity and reduced glutathione (GSH) level in tissue homogenates. Furthermore, venom-induced increases in serum levels of organ dysfunction markers (lactate deshydrogenase, aminotransferase ALT and AST, creatinine and urea) were also significantly suppressed by pre-treatment with TLR4 inhibitor, concordantly with a remarkable improvement in the histological features in lung and liver tissues. The results of the present study indicate the potential role of TLR4 in venom-induced immunopathology and show the in vivo requirement of TLR4 signaling in mediating venom-induced tissue damage.

Abstract
Elevated levels of endothelin-1 (ET-1) were recorded in sera of scorpion sting patients. However, no studies focused on the mechanism of ET-1 involvement in the pathogenesis of scorpion envenomation, particularly in the cardiovascular system which is seriously affected in severe cases of scorpion stings. Inflammation induced by Androctonus australis hector (Aah) scorpion venom in the heart together with the aorta was studied in mice pretreated with a specific endothelin A receptor (ETA-R) inhibitor. ETA-R inhibition resulted in the attenuation of the high amounts of cytokine (tumor necrosis factor alpha (TNF-α) and interleukin-17 (IL-17)) recorded in the sera of envenomed mice. The recovery of the oxidative stress marker balance and matrix metalloproteinase (MMP) expression were also observed, concomitantly with the reduction of tissular neutrophil infiltration. Additionally, the cardiac and the aortic tissue alterations, and the metabolic enzymes (creatine kinase (CK) and muscle–brain isoform creatine kinase (CK-MB)) overspread into sera were significantly attenuated. Obtained results suggest the implication of endothelin throughout its ETA receptors in the inflammatory response observed in the cardiovascular components during scorpion envenomation. Further knowledge is needed to better understand the implication of the endothelin axis and to improve the therapeutic management of severe scorpion sting cases.

Abstract
Because of their venom lethality towards mammals, scorpions of the Androctonus genus are considered a critical threat to human health in North Africa. Several decades of exploration have led to a comprehensive inventory of their venom components at chemical, pharmacological, and immunological levels. Typically, these venoms contain selective and high affinity ligands for the voltage-gated sodium (Nav) and potassium (Kv) channels that dictate cellular excitability. In the well-studied Androctonus australis and Androctonus mauretanicus venoms, almost all the lethality in mammals is due to the so-called α-toxins. These peptides commonly delay the fast inactivation process of Nav channels, which leads to increased sodium entry and a subsequent cell membrane depolarization. Markedly, their neutralization by specific antisera has been shown to completely inhibit the venom’s lethal activity, because they are not only the most abundant venom peptide but also the most fatal. However, the structural and antigenic polymorphisms in the α-toxin family pose challenges to the design of efficient serotherapies. In this review, we discuss past and present accomplishments to improve serotherapy against Androctonus scorpion stings.

Cerebrospinal inflammatory response following scorpion envenomation: role of histamine H1 and H3 receptors. Inflammopharmacology 2019; 27:589-601.

Abstract
BACKGROUND The mechanism of the inflammatory process induced by scorpion venom in the cerebrospinal tissues has not yet been completely elucidated. Therefore, we aimed to investigate the role of histamine through its H1 and H3 receptors in this process. METHODS Histamine H1 and H3 receptor antagonists, Hydroxyzine (10 mg/kg) and Betaserc (20 mg/kg), respectively, were administered by intraperitoneal route to mice 1 h before subcutaneous envenomation with a subletal dose (0.5 mg/kg) of Androctonus australis hector venom. Cerebrospinal inflammation response was assessed 24 h after envenomation by evaluating the vascular permeability changes, inflammatory cell infiltration, oxidative/nitrosative stress marker levels (hydrogen peroxide, nitric oxide, malondialdehyde, glutathione and catalase) and by histological examination of cerebrospinal tissue. RESULTS Envenomed mice displayed an installation of an inflammatory response marked by increased vascular permeability (76% and 68% in brain and spinal cord, respectively, in comparison to controls), inflammatory cell infiltration, increased pro-oxidant levels and decreased anti-oxidant markers (p < 0.05 to p < 0.001). Scorpion venom also induced structural changes in brain and spinal cord tissues. Hydroxyzine seemed to be more efficient than Betaserc in the prevention of the induced cerebrospinal inflammation response, as evidenced by the decreased vascular permeability, inflammatory cell infiltration, pro-oxidant levels, increased anti-oxidant defense (p < 0.05 to p < 0.001) and a reduction of the anatomo-pathological alterations. CONCLUSION The results showed that the histamine H1 receptor is more involved in the induced central nervous system inflammatory response during scorpion envenomation.

TNF-α antagonist improves oxidative stress and lipid disorders induced by scorpion venom in the intestinal tissue. Acta Trop 2018; 185:307-313.

Abstract
We previously reported that Androctonus australis hector (Aah) venom induces inflammation in several tissues, however limited information is available on its role in gastrointestinal tract. Here we evaluate the involvement of TNF-α in lipid metabolism in the small intestine after Aah envenomation. To address these issues, NMRI mice (3-month-old) were pre-treated with a TNF-α antagonist, 30 min prior to Aah venom injection. Redox status, cytotoxicity and histopathological changes were analyzed in small intestine 3 and 24 h after Aah injection. Lipid metabolism was evaluated through lipid tolerance test in sera. Lipid content in small intestine was also evaluated at different times after envenomation. Obtained results showed that Aah venom affects the intestinal integrity. This cytotoxicity could be associated with lipid peroxidation and altered or insufficient antioxidant system. These results also highlight the perturbation of lipid absorption in intestine tissue of envenomed mice. The use of TNF-α antagonist prior to Aah venom injection seems to be able to improve lipid profile, oxidative stress and antioxidant activity. These findings suggest that Aah venom induces lipid alterations in the intestinal tissue mechanisms involving of TNF- α.

Abstract
Tityus serrulatus is the scorpion associated with the most severe cases of scorpion envenoming in Brazil. However, there are no studies reporting the genotoxic effects of this venom in natural or experimental envenomations. It is well known that DNA-damage responses are providing opportunities for improving disease detection and management. In this study was evaluating the genotoxicity of the T. serrulatus venom in different organs (hippocampus, cortex, striatum, blood, heart, lung, liver and kidney) and periods in mice experimentally envenomed. ELISA and the Comet assays were used to quantification of venoms antigens and DNA damage, respectively. Forty-eight Swiss mice were divided into five groups and 0.5 DL50 of T. serrulatus venom (0.90 mg/kg) was administered intraperitoneally in each animal. Euthanasia was performed by cervical dislocation in the period of 0h (control group) 1h, 2h, 6h and 12h, where it the tissues were removed. The results showed high DNA damage in all structures analyzed, suggesting that T. serrulatus venom presented genotoxic activity or some secondary effect generated by venom injection. In the ELISA test, toxic circulant antigens were verified in practically all organs at the time intervals analyzed. Therefore, the distribution of the venom changes from organ to organ. We conclude that scorpion envenoming affects DNA in all organs analyzed even when the venom concentration is lower or no detectable, DNA damage persists.

Abstract
Scorpion envenomation injures a number of organs, including the kidney. Mechanisms proposed to explain the renal tubule injury include direct effects of venom on tubule epithelial cells, as well as indirect effects of the autonomic nervous system, and inflammation. Here, we report direct effects of Androctonus australis hector (Aah) scorpion venom on the viability of Renal Proximal Tubule (RPT) cells in vitro, unlike distal tubule and collecting duct cells. Extensive NucGreen nuclear staining was observed in immortalized rabbit RPT cells following treatment with Aah venom, consistent with cytotoxicity. The involvement of oxidative stress is supported by the observations that 1) anti-oxidants mitigated the Aah venom-induced decrease in the number of viable RPT cells, and 2) Aah venom-treated RPT cells were intensively stained with the CellROX(®) Deep Red reagent, an indicator of Reactive Oxygen Species (ROS). Relevance to normal RPT cells is supported by the red fluorescence observed in Aah venom treated primary rabbit RPT cell cultures following their incubation with the Flica reagent (indicative of caspase activation and apoptosis), and the green fluorescence of Sytox Green (indicative of dead cells).

Abstract
Bradykinins are released from kininogen by kallikrein. They increase capillary lung permeability after their binding to β1 and especially β2 receptors before being metabolized by kininase enzyme. This study was performed to evaluate cardiopulmonary damages and inflammatory response on injected rats with Aah I toxin of scorpion venom and the involvement of Kallikrein-Kinin system in this pathogenesis. Obtained results revealed that Aah I toxin induces inflammatory cell infiltration accompanied by cellular peroxidase activities, a release of cytokine levels, pulmonary and myocardial damage, with altered metabolic activities and imbalanced redox status. Administration of aprotinin (bradykinin inhibitor) and especially icatibant (bradykinin β2 receptor antagonist) seemed to be able to protect animals against the toxicity of Aah I; nevertheless, the use of captopril (kininase II inhibitor) reduced partially some cardiac disorders. These findings indicate that the kallikrein-kinin system may contribute to the physiopathological effect and lung edema formation induced by toxin, which suggests a potential use of drugs with significant anti-kinin properties.
