Article Abstract
The aim of this study was to assess the relationship between the expression of the CD23 molecule on B-cells and the levels of specific IgE against allergens and molecular components of storage mites (Gly d 2, Lep d 2), dog (Can f 1, Can f 2), cat (Fel d 1), shrimp (Pen m 2), molds (Asp f 6, Mala s 11, Alt a 6, Alt a 1, Mala s 6, Cla h), and German cockroach (Bla g 9) in atopic dermatitis (AD) patients (with and without dupilumab therapy). Here, 46 patients with AD were included (26 without dupilumab treatment, 20 with dupilumab treatment). Serum levels of specific IgE were measured using the component-resolved diagnostic microarray ALEX2 Allergy Xplorer, and the expression of the CD23 molecule on B-cells was evaluated using flow cytometry. For statistical analysis, a Spearman's rank correlation was used. The data indicated there was a higher correlation between CD23 expression on B-cells and specific IgE against molecular components of storage mites Bla g 9 (up to 27%), cat Fel d 1 (22.7%), and allergen extract Cla h () up to 38.9% in AD patients treated with dupilumab. These results regarding the higher association suggested a significant role in the non-inflammatory clearance and uptake of these specific IgE antibodies.

Objective: Aim: To evaluate clinical applicability of immune mediator's interleukin-16, immunoglobulin E along with eosinophil count in diagnosing COVID-19 and determining its severity.
Patients And Methods: Materials and Methods: Cross-sectional case-control study was conducted at Al-Najaf General Hospital, Najaf, Iraq between March and August 2024. 120 participants: 60 confirmed COVID-19 cases and 60 healthy controls which matched cases in terms of age and sex.

Prcis: Analysis of 1,175 Korean adults in the 2019 KNHANES study found that sensitization to house dust mites and birch pollen significantly increased glaucoma risk, while oak pollen sensitization showed a protective effect.
Background: The relationship between allergen sensitization and glaucoma remains poorly understood. This study investigated the association between specific allergen sensitization patterns and glaucoma risk using data from the 2019 Korea National Health and Nutrition Examination Survey.

NSG-SGM3 humanized mouse models are well-suited for studying human immune physiology but are technically challenging and expensive. We previously characterized a simplified NSG-SGM3 mouse, engrafted with human donor CD34 hematopoietic stem cells without receiving prior bone marrow ablation or human secondary lymphoid tissue implantation, that still retains human mast cell- and basophil-dependent passive anaphylaxis responses. Its capacities for human antibody production and human B cell maturation, however, remain unknown.

Mast cells (MCs) rapidly adapt to the microenvironment due to the plethora of cytokine receptors expressed. Understanding microenvironment-primed immune responses is essential to elucidate the phenotypic/functional changes MCs undergo, and thus understand their contribution to diseases and predict the most effective therapeutic strategies. We exposed primary human MCs to cytokines mimicking a T1/pro-inflammatory (IFNγ), T2/allergic (IL-4 + IL-13), alarmin-rich (IL-33) and pro-fibrotic/pro-tolerogenic (TGFβ) microenvironment.

Objective: To investigate whether sublingual immunotherapy (SLIT) with house dust mite (HDM) extract suppresses new sensitization to Japanese cedar pollen(JCP) in children with HDM-positive allergic rhinitis.
Methods: This retrospective study was conducted at our center and included pediatric patients aged 5-15 years who visited between January 2018 and December 2020. Eligible patients tested positive for HDM-specific immunoglobulin E (IgE), negative for JCP-specific IgE, and had no history of SLIT for cedar pollen.
