ALLERGIC CONTACT DERMATITIS AND ATOPIC DERMATITIS: HIGHLIGHTS OF THE OVERLAP SYNDROME

Клінічна та профілактична медицина
Introduction. The combination of atopic dermatitis (AD) with allergic contact dermatitis (ACD) or the occurrence of ACD on the background of atopic dermatitis is called the overlap syndrome.

Hapten synthesis and production of specific antibody against 3-amino-5-morpholinomethyl-2-oxazolidone for immunoassay without derivatisation

Food and Agricultural Immunology, 2018
Immunoassay direct for 3-amino-5-morpholinomethyl-2-oxazolidone (AMOZ), the metabolite of furaltadone, based on a specific antibody was usually unavailable due to its small molecule weight. In this work, a hapten with a double bond and an active carboxyl

Synthesis and Immunological Evaluation of Virus-Like Particle-Milbemycin A3/A4 Conjugates

Antibiotics, 2017
Milbemycins are macrolide antibiotics with a broad spectrum of nematocidal, insecticidal, and acaricidal activity. To obtain milbemycin A3/A4 derivatives suitable for chemical conjugation to protein carriers (milbemycin haptens), succinate linker and a ...

Dimerization kinetics of the IgE-class antibodies by divalent haptens. I. The Fab-hapten interactions [PDF]

, 1992
The binding of divalent haptens to IgE-class antibodies leads predominantly to their oligomerization into open and closed dimers. Kinetics of the open dimer formation was investigated by fluorescence titrations of Fab fragments of monoclonal DNP-specific

Successful Application of the Mast Cell Activation Test in Immediate Hypersensitivity to Amoxicillin

Allergy, EarlyView.
This study included 28 amoxicillin‐allergic patients and 11 healthy exposed controls. Mast cells were differentiated from CD34+ progenitors over 8 weeks using cytokine cocktails. The mast cell activation test involved sensitization with patient or control sera and stimulation with free amoxicillin or G4/G5‐AXO dendrimers with successfully activated ...

Hapten-Induced Contact Hypersensitivity, Autoimmune Reactions, and Tumor Regression: Plausibility of Mediating Antitumor Immunity

Journal of Immunology Research, 2014
Haptens are small molecule irritants that bind to proteins and elicit an immune response. Haptens have been commonly used to study allergic contact dermatitis (ACD) using animal contact hypersensitivity (CHS) models.

Identification and Application of Two Promising Peptide Ligands for the Immunodetection of Imidacloprid Residue

Foods, 2022
As the most widely used neonicotinoid insecticide, it is of great significance to explore the immunoreagents and immunoassays for imidacloprid (IMI) residue.

Skin Sensitisation and Dermatitis Among Epoxy-Exposed Workers in a Wind Turbine Plant: Influence of Occupational Factors. [PDF]

Contact Dermatitis
Epoxy resin sensitisation remains a relevant occupational risk in wind turbine blade manufacturing, confined to high‐exposure tasks and often presenting as hand dermatitis. Accurate diagnosis requires epoxy‐specific patch testing, and prevention must go beyond personal protective equipment.

T cell receptor (TCR) interaction with haptens: metal ions as non-classical haptens [PDF]

, 2005
Haptens are classified as low molecular chemicals with an intrinsic potential to covalently modify proteins, and many of them are strong inducers of contact hypersensitivity (CHS).

Emollient Formulations and Skin Barrier Practices in the Context of Eczema and Food Allergy Prevention

Allergy, EarlyView.
ABSTRACT The skin is far from a passive shield; it functions as a dynamic “living barrier” whose structural and immunological integrity is paramount in preventing atopic dermatitis (AD) and the subsequent progression of the atopic march toward food allergy (FA).
