Abstract
Background Asparaginase (ASNase) is a crucial part of acute leukemia treatment, but immune responses to the agent can reduce its effectiveness and increase the risk of relapse. Currently, no reliable and validated biomarker predicts ASNase-induced hypersensitivity reactions during therapy. We aimed to identify predictive biomarkers and determine immune cells responsible for anaphylaxis using a murine model of ASNase hypersensitivity. Methods Our preclinical study uses a murine model to investigate predictive biomarkers of ASNase anaphylaxis, including anti-ASNase antibody responses, immune complex (IC) levels, ASNase-specific binding to leukocytes or basophils, and basophil activation. Results Our results indicate that mice immunized to ASNase exhibited dynamic IgM, IgG, and IgE antibody responses. The severity of ASNase-induced anaphylaxis was found to be correlated with levels of IgG and IgE, but not IgM. Basophils from immunized mice were able to recognize and activate in response to ASNase ex vivo, and the extent of recognition and activation also correlated with the severity of anaphylaxis observed. Using a multivariable model that included all biomarkers significantly associated with anaphylaxis, independent predictors of ASNase-induced hypersensitivity reactions were found to be ASNase IC levels and ASNase-specific binding to leukocytes or basophils. Consistent with our multivariable analysis, we found that basophil depletion significantly protected mice from ASNase-induced hypersensitivity reactions, supporting that basophils are essential and can be used as a predictive marker of ASNase-induced anaphylaxis. Conclusions Our study demonstrates the need for using tools that can detect both IC- and IgE-mediated hypersensitivity reactions to mitigate the risk of ASNase-induced hypersensitivity reactions during treatment.

Abstract
BACKGROUND Studies of passive anaphylaxis, in which mouse immunoglobulin G (IgG) and its antigens are administered to mice, believe that platelet-activating factor (PAF) is more important than histamine and that basophils or macrophages are primarily involved. However, the full extent of IgG-dependent anaphylaxis is still unclear; that is, little agreement has been reached about the mechanism. METHODS First, we established the novel model of IgG1 anaphylaxis induced by the intravenous administration of two types of IgG1 and a fluorescent dye-labeled antigen, as IgG1 immune complex in HR-1 hairless mice. Subsequently, pharmacological analysis was used to investigate the underlying mechanisms of IgG1 anaphylaxis in this established model. RESULTS The novel IgG1 anaphylaxis model can induce the IgG-induced Anaphylaxis-dependent Spotted Distribution of fluorescently labeled Immune complexes in the Skin, named "G-ASDIS". Moreover, this model was triggered primarily by the FcγRIII-dependent histamine release, which is different from the conventional model in which PAF was involved in the development of IgG1 anaphylaxis. Basophils in the circulation and mast cells in the skin may participate in the development of IgG1 anaphylaxis and increased G-ASDIS. CONCLUSION Our results propose that the novel axis, namely the FcγRIII-basophils and/or mast cell-histamine pathway, is important for IgG1 anaphylaxis. Further analysis of our model in addition to other models will lead to a broader analysis and understanding of the IgG1 anaphylaxis mechanism.

Treatment of SARS-CoV-2-induced pneumonia with NAD + and NMN in two mouse models. Cell Discov 2022; 8:38.

Abstract
The global COVID-19 epidemic has spread rapidly around the world and caused the death of more than 5 million people. It is urgent to develop effective strategies to treat COVID-19 patients. Here, we revealed that SARS-CoV-2 infection resulted in the dysregulation of genes associated with NAD+ metabolism, immune response, and cell death in mice, similar to that in COVID-19 patients. We therefore investigated the effect of treatment with NAD+ and its intermediate (NMN) and found that the pneumonia phenotypes, including excessive inflammatory cell infiltration, hemolysis, and embolization in SARS-CoV-2-infected lungs were significantly rescued. Cell death was suppressed substantially by NAD+ and NMN supplementation. More strikingly, NMN supplementation can protect 30% of aged mice infected with the lethal mouse-adapted SARS-CoV-2 from death. Mechanically, we found that NAD+ or NMN supplementation partially rescued the disturbed gene expression and metabolism caused by SARS-CoV-2 infection. Thus, our in vivo mouse study supports trials for treating COVID-19 patients by targeting the NAD+ pathway.

Critical Signaling Events in the Mechanoactivation of Human Mast Cells through p.C492Y-ADGRE2. J Invest Dermatol 2020; 140:2210-2220.e5.

Abstract
A role for the adhesion G-protein coupled receptor ADGRE2 or EMR2 in mechanosensing was revealed by the finding of a missense substitution (p.C492Y) associated with familial vibratory urticaria. In these patients, friction of the skin induces mast cell hyper-degranulation through p.C492Y-ADGRE2, causing localized hives, flushing, and hypotension. We have now characterized the responses and intracellular signals elicited by mechanical activation in human mast cells expressing p.C492Y-ADGRE2 and attached to dermatan sulfate, a ligand for ADGRE2. The presence of p.C492Y-ADGRE2 reduced the threshold to activation and increased the extent of degranulation along with the percentage of mast cells responding. Vibration caused phospholipase C activation, transient increases in cytosolic calcium, and downstream activation of phosphoinositide 3-kinase and extracellular signal-regulated kinases 1 and 2 by Gβγ, Gαq/11, and Gαi/o-independent mechanisms. Degranulation induced by vibration was dependent on phospholipase C pathways, including calcium, protein kinase C, and phosphoinositide 3-kinase but not extracellular signal-regulated kinases 1/2 pathways, along with pertussis toxin-sensitive signals. In addition, mechanoactivation of mast cells stimulated the synthesis and release of prostaglandin D2, to our knowledge a previously unreported mediator in vibratory urticaria, and extracellular signal-regulated kinases 1/2 activation was required for this response together with calcium, protein kinase C, and to some extent, phosphoinositide 3-kinase. Our studies thus identified critical molecular events initiated by mechanical forces and potential therapeutic targets for patients with vibratory urticaria.

Abstract
Basophils are granulocytes involved in parasite immunity and allergic diseases, known for their potent secretion of type 2 cytokines. Identifying their functions has proven to be controversial due to their relative rarity and their complex lineage phenotype. Here, we show that the expression of basophils lineage markers CD200R3 and FcεRIα is highly variable in inflammatory settings and hinders basophils identification by flow cytometry across multiple disease states or tissues. Fluorophore-conjugated antibody staining of these lineage markers strongly activates basophil type 2 cytokine expression, and represents a potential bias for coculture or in vivo transfer experiments. The Basoph8 is a mouse model where basophils specifically express a strong fluorescent reporter and the Cre recombinase. Basophils can be identified and FACS sorted unambiguously by their expression of the enhanced yellow fluorescent protein (eYFP) in these mice. We show that the expression of the eYFP is robust in vivo during inflammation, and in vitro on living basophils for at least 72 h, including during the induction of anaphylactoid degranulation. We bred and characterized the Basoph8xiDTR mice, in which basophils specifically express eYFP and the simian diphtheria toxin receptor (DTR). This model enables basophils conditional depletion relatively specifically ex vivo and in vivo during allergic inflammation and their detection as eYFP+ cells. In conclusion, we report underappreciated benefits of the commercially available Basoph8 mice to study basophils function.

Abstract
Identifying the causes of anaphylaxis which is an acute, potentially fatal systemic reaction is very important in every community. Treatment strategies and pitfalls should also be determined. We sought to determine the most common triggers of anaphylaxis, clinical manifestations and treatment strategies in Mashhad, northeast of Iran. An observational cross-sectional study was conducted to evaluate all patients with a history of anaphylactic reaction who were referred to University Allergy Clinics between 2006 and 2016 in Mashhad Iran. We used a combination of patient’s clinical history and allergy diagnostic testing including radioallergosorbant test and skin prick test in order to determine the etiology of anaphylaxis. We identified 172 anaphylactic reactions in 70 patients. Median age was 15 years with a range from 6 months to 48 years. The triggers included: foods, 61.4%; drugs, 15.7%; hymenoptera venom, 8.6%; idiopathic, 5.7%; immunotherapy, 4.3% and other etiologies: 5.7%. Nuts and seeds were the most important triggers of food induced anaphylaxis, especially in school children, adolescents and young adults, followed by fruits. However, Cow’s milk and hen’s egg were the main triggers of anaphylaxis in children aged under 2 years. The most common symptoms were cutaneous and cardiovascular. Corticosteroids (94.3%) and/or antihistamines (85.7%) were used most frequently for treatment followed by intravenous fluids (54.3%), whereas epinephrine was only used in 17.1% of the cases. Food related anaphylaxis and other typical triggers of anaphylaxis are age dependent and the risks and triggers change with age. Epinephrine injection should be increased by improving the awareness of physician and medical teams. The study was approved by the Ethics Committee of the Faculty of Medicine of Mashhad University of Medical Sciences (approved number: IR.MUMS.REC.1393.960).
