Mast Cells in Host Defense Against Cutaneous Staphylococcus aureus Infection

Immunology &Cell Biology, EarlyView.
Impact of S. aureus epicutaneous sensitization models on mast cell function in vivo. D. farinae and Staphylococcal enterotoxin B (SEB) activate Trpv1+ Tac1+ nociceptors to trigger the release of substance P (SP), which promotes mast cell degranulation through Mrgprb2. S.

Age at Onset of Asthma and Allergen Sensitization Early in Life

Allergology International, 2014
Background: Epidemiological evidence indicates that the age at onset of asthma and allergen sensitization in early life is decreasing in people from Western countries. To explore latent trends, we conducted a retrospective examination of the age at onset

Plant‐Based Production of Human Major Histocompatibility Complex Class II Molecules

Plant Biotechnology Journal, EarlyView.
ABSTRACT Major histocompatibility complex class II (MHC II) protein triggers adaptive immune responses by presenting antigens on antigen‐presenting cells (APCs) to be recognised by CD4+ T cells. Recombinant MHC II proteins are effective for the analysis of peptide‐binding interaction, detection of antigen‐specific T‐cells and clinical testing for donor‐

Edible Insect Allergens: An Emerging Food Safety Challenge

Sustainable Food Proteins, Volume 4, Issue 3, September 2026.
Allergic responses to edible insects arise via two main pathways: cross‐reactivity with homologous arthropod allergens and primary sensitization to edible insect proteins, both leading to IgE‐mediated immune activation. ABSTRACT Edible insects are increasingly promoted as sustainable protein sources; however, their allergenic potential remains a ...

Assessment of Allergenic Potential for Cross‐Reactivity of Olive (Olea europaea) Pit Xylo‐Oligosaccharide‐Rich Extract With Legislated Allergens in the European Union

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Spray‐dried xylo‐oligosaccharide‐rich extract derived from olive pit endocarps was assessed for potential cross‐reactivity using in vitro ELISA and in silico approaches. The ELISA tests indicated potential cross‐reactivities with nuts (hazelnut, almond, pistachio, peanut), gluten, and milk in certain batches.

Low Potency of Indian Dust Mite Allergen Skin Prick Test Extracts Compared to FDA-Approved Extracts: A Double-Blinded Randomized Control Trial

Allergy & Rhinology, 2018
Background Skin prick testing is the most important diagnostic tool to detect immunoglobulin E-mediated allergic diseases. With increase in the number of allergy tests performed in India, it is imperative to know the potency of indigenous extracts in ...

In vitro antigen-specific sulphidoleukotriene production in patients allergic to Dermatophagoides pteronyssinus

Revista de Medicina de la Universidad de Navarra, 1998
BackgroundSulphidoleukotrienes (slt) are important mediators in allergic diseases that are synthesized after allergen‐specific stimulation.ObjectivesThe aim of this study is to determine in vitro slt production after allergen‐specific (Dermatophagoides pteronyssinus) stimulus of peripheral blood leucocytes and to observe whether histamine release in ...

Longitudinal Analysis of Seasonal Variations in Intradermal Test Reactivity and Serum Allergen‐Specific Immunoglobulin E in Dogs With Atopic Dermatitis

Veterinary Dermatology, Volume 37, Issue 4, Page 511-521, August 2026.
Background: In dogs with atopic dermatitis (AD), allergen testing is often timed to pollen exposure. However, data on seasonal effects on intradermal testing (IDT) and allergen‐specific immunoglobulin (Ig)E serology (SAT) are limited. Objectives: To evaluate the seasonal effects on IDT and SAT results in dogs with AD by comparing aeroallergen test ...

Sema3E‐plexinD1 Axis Is a Modulator of Foxp3+ Regulatory T‐Cells in House Dust Mite Model of Asthma

The FASEB Journal, Volume 40, Issue 14, 31 July 2026.
Airway epithelial‐derived Sema3E enhances both the number and proliferation of Foxp3+ regulatory T (Treg) cells in an acute model of asthma. Mechanistically, deletion of PlexinD1, the receptor for Sema3E, specifically in Foxp3+ cells was associated with a breakdown in immune regulation in this model.
