Combining avidin with CD63 improves basophil activation test accuracy in classifying peanut allergy. Allergy 2024; 79:445-455. [PMID: 37916710 PMCID: PMC10842984 DOI: 10.1111/all.15930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 10/11/2023] [Accepted: 10/12/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND Conventional basophil activation tests (BATs) measure basophil activation by the increased expression of CD63. Previously, fluorophore-labeled avidin, a positively-charged molecule, was found to bind to activated basophils, which tend to expose negatively charged granule constituents during degranulation. This study further compares avidin versus CD63 as basophil activation biomarkers in classifying peanut allergy. METHODS Seventy subjects with either a peanut allergy (N = 47), a food allergy other than peanut (N = 6), or no food allergy (N = 17) were evaluated. We conducted BATs in response to seven peanut extract (PE) concentrations (0.01-10,000 ng/mL) and four control conditions (no stimulant, anti-IgE, fMLP (N-formylmethionine-leucyl-phenylalanine), and anti-FcεRI). We measured avidin binding and CD63 expression on basophils with flow cytometry. We evaluated logistic regression and XGBoost models for peanut allergy classification and feature identification. RESULTS Avidin binding was correlated with CD63 expression. Both markers discriminated between subjects with and without a peanut allergy. Although small by percentage, an avidin+ /CD63- cell subset was found in all allergic subjects tested, indicating that the combination of avidin and CD63 could allow a more comprehensive identification of activated basophils. Indeed, we obtained the best classification accuracy (97.8% sensitivity, 96.7% specificity) by combining avidin and CD63 across seven PE doses. Similar accuracy was obtained by combining PE dose of 10,000 ng/mL for avidin and PE doses of 10 and 100 ng/mL for CD63. CONCLUSIONS Avidin and CD63 are reliable BAT activation markers associated with degranulation. Their combination enhances the identification of activated basophils and improves the classification accuracy of peanut allergy.

Induction of the apoptosis, degranulation and IL-13 production of human basophils by butyrate and propionate via suppression of histone deacetylation. Immunology 2021; 164:292-304. [PMID: 33999409 PMCID: PMC8442238 DOI: 10.1111/imm.13370] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 04/16/2021] [Accepted: 04/30/2021] [Indexed: 11/29/2022] Open
Abstract
Allergic diseases are caused by dysregulated Th2 immune responses involving multiple effector cells including basophils. Short chain fatty acids (SCFAs), mainly acetate, propionate and butyrate, exert immunomodulatory functions via activation of its receptors GPR41 and GPR43, and inhibition of the histone deacetylases (HDACs) activity. In allergic diseases, SCFAs suppress the activity of mast cells, eosinophils and type 2 innate lymphoid cells (ILC2) but enhance the function of Th2 cells. Here, we aimed to elucidate the function of SCFAs on human basophils. Human basophils were purified from healthy donors by flow cytometric sorting. The surface proteins, apoptosis and degranulation of basophils were analyzed by flow cytometric analysis. The mRNA expression was assayed using real-time PCR. Interleukin 4 (IL-4) and IL-13 were measured by ELISA. Histone acetylation was examined by western blot. GPR41 was expressed by basophils and was enhanced by IL-3. Acetate induced intracellular calcium influx in basophils which was suppressed by blocking GPR41. Propionate and butyrate, but not acetate, induced the expression of CD69 and IL-13. In addition, propionate and butyrate enhanced IgE-mediated basophil degranulation but inhibited basophil survival and IL-4 secretion. Propionate and butyrate induced histone acetylation of basophils and suppression of HDACs activity mimicked the effects of propionate and butyrate on human basophils. Our findings demonstrate that propionate and butyrate may play a complex role in regulating basophil apoptosis, activation and degranulation via inhibiting HDACs activity. The in vivo effects of SCFAs on the regulation of basophil-associated allergic diseases need to be further explored.

Abstract
Interactions between malignant cells and neighboring stromal and immune cells profoundly shape cancer progression. New forms of therapies targeting these cells have revolutionized the treatment of cancer. However, in order to specifically address each population, it was essential to identify and understand their individual roles in interaction between malignant cells, and the formation of the tumor microenvironment (TME). In this review, we focus on the myeloid cell compartment, a prominent, and heterogeneous group populating TME, which can initially exert an anti-tumoral effect, but with time actively participate in disease progression. Macrophages, dendritic cells, neutrophils, myeloid-derived suppressor cells, mast cells, eosinophils, and basophils act alone or in concert to shape tumor cells resistance through cellular interaction and/or release of soluble factors favoring survival, proliferation, and migration of tumor cells, but also immune-escape and therapy resistance.

Abstract
BACKGROUND Mas-related G protein-coupled receptor X2 (MRGPRX2) is regarded as a mast cell-specific receptor mediating non-IgE-dependent activation. We aimed to investigate whether human basophils and eosinophils express functional MRGPRX2. METHODS Flow cytometry, immunocytochemistry, immunofluorescence, Western blot, and RT-PCR were performed in highly purified peripheral blood basophils and eosinophils of atopic and nonatopic donors. To assess functional activity, fluorescent avidin-based degranulation assay, calcium mobilization, cytokine production in supernatants, assessment of viability/apoptosis, and tricolor granulocyte activation test were used. RESULTS MRGPRX2 was significantly expressed by basophils and eosinophils but not neutrophils. Functional capacity was shown by anti-MRGPRX2 mAb-induced calcium influx and concentration-dependent induction of degranulation. Sequential stimulation in the calcium mobilization assay gave no evidence for desensitization or receptor internalization. Anti-MRGPRX2 mAb significantly promoted survival. Inhibition of apoptosis could be due to released IL-3, IL-5, and GM-CSF found in supernatants. Short-term incubation with IL-3 dose-dependently upregulated MRGPRX2 expression in both, stimulation for 24 hours with anti-IgE, C5a, fMLP, and IL-3 in basophils and by IL-3, IL-5, and IL-33 in eosinophils. Among known mast cell MRGPRX2 agonists ciprofloxacin but not PMX-53 was functional on basophils and eosinophils. In basophils of allergic subjects, tricolor granulocyte activation test using grass pollen demonstrated MRGPRX2 upregulation associated with degranulation and CD63 expression. CONCLUSION Unraveling the regulation and signaling mechanisms of MRGPRX2 on basophils and eosinophils might enable the development of new therapeutic strategies to prevent or inhibit allergic and nonallergic hypersensitivity. Moreover, addressing MRGPRX2 might have potential for diagnostic purposes in (drug) hypersensitivity.

Abstract
Food allergy has reached epidemic proportions and has become a significant source of healthcare burden. Oral food challenge, the gold standard for food allergy assessment, often is not performed because it places the patient at risk of developing anaphylaxis. However, conventional alternative food allergy tests lack a sufficient predictive value. Therefore, there is a critical need for better diagnostic tests that are both accurate and safe. Microfluidic methods have the potential of helping one to address such needs and to personalize the diagnostics. This article first reviews conventional diagnostic approaches used in food allergy. Second, it reviews recent efforts to develop novel biomarkers and in vitro diagnostics. Third, it summarizes the microfluidic methods developed thus far for food allergy diagnosis. The article concludes with a discussion of future opportunities for using microfluidic methods for achieving precision diagnostics in food allergy, including multiplexing the detection of multiple biomarkers, sampling of tissue-resident cytokines and immune cells, and multi-organ-on-a-chip technology.

Abstract
The basis of traditional flow cytometry allergy diagnosis is measurement of the expression of basophilic surface activation and/or degranulation markers. Basophils, upon encounter with a specific allergen that cross-links surface FcRI-bound IgE antibodies, not only secrete and release quantifiable bioactive mediators but also upregulate the expression of different markers (e.g., CD63, CD203c) which can be detected by multicolor flow cytometry using specific monoclonal antibodies. Here, we describe a novel technique that relies upon the staining of exteriorized anionic proteoglycans from a basophil granule matrix by cationic fluorescent avidin probes.

Abstract
BACKGROUND Correct diagnosis of immediate drug hypersensitivity reactions (IDHRs) can pose a significant challenge, mainly because of the absence of reliable in vitro tests, uncertainties associated with skin testing, and incomplete understanding of the underlying mechanisms. AIM To summarize and hypothesize on the potential of basophil activation test (BAT) as a safe aid to explore the mechanistic endotypes of IDHR, to identify antibody recognition sites, and to monitor drug desensitization. METHODS A literature search was conducted using the keywords "allergy, basophil activation, CD63, CD203c, diagnosis, drugs, hypersensitivity, flow cytometry"; this was complemented by the authors' own expertise. RESULTS At present BAT has mainly been employed as a diagnostic aid. However, evidence is emerging that the technique might also deepen our insights in immune (allergic) and nonimmune (nonallergic) mechanistic processes of IDHR. It is anticipated that BAT might also benefit the identification of antibody recognition sites and benefit our understandings of desensitization strategies. CONCLUSION Although the nondiagnostic application of BAT in IDHR is still in its infancy, with increasing employment, we can expect the technique to become a valuable asset to study many domains of IDHR that remain poorly understood.

Abstract
'Precision Medicine' embodies the analyses of extensive data collected from patients and their environments to identify and apply patient-specific prophylactic strategies and medical treatments to improve clinical outcomes and healthcare cost-effectiveness. Many new methods have been developed for evaluating the activity of the human immune system. Such 'immune monitoring' approaches are now being used in studies of allergy and asthma in the hope of identifying better correlates of disease status, predictors of therapeutic outcomes, and potential side-effects of treatment. Together with analyses of family histories, genetic and other biometric data, and measurements of exposures to environmental and other risk factors for developing or exacerbating disease, immune monitoring approaches promise to enable 'Precision Medicine' for allergic diseases and asthma.
