Currently, there is no FDA-approved therapy for food allergy. Several new potential treatments are under investigation, including food allergen immunotherapy via various routes of administration, such as oral immunotherapy, epicutaneous therapy, subcutaneous immunotherapy, and sublingual immunotherapy. The double-blind, placebo-controlled food challenge has traditionally been used for diagnostic purposes, but extrapolation of the specific terminology used in food allergy diagnosis to interpretation of efficacy in clinical trials is incongruent and difficult to apply.

Nickel is a component of several alloy types that are widely used in our environment, including several dental alloy types that cause intraoral metal contact allergy. However, metal-specific immune responses in the oral mucosa have not been elucidated because a suitable animal model has not been established. In this study, we established a novel murine model of nickel-induced intraoral metal contact allergy and aimed to elucidate the immune response in terms of T-cell receptor repertoire and cytokine profiles in inflamed oral mucosa.

Background: In previous studies, we suggested that Acanthamoeba is a new aero-allergen and that patients who showed positive results for the skin-prick test response to Acanthamoeba cross-reacted with several pollen allergens. Additionally, patients with common antibodies reacted to the 13-15 kDa Acanthamoeba unknown allergen.
Objective: We examined whether profilin of Acanthamoeba is a human airway allergic agent because of its molecular weight. Read More

Objective: To investigate the potential effect of miR-487b/IL-33-ST2 axis on the pathology of allergic rhinitis (AR) and the relevant mechanism.
Patients And Methods: The expression level of interleukin-33 (IL-33), a homolog of sulfotransferase (ST2), and miR-487b were detected in patients with or without allergic rhinitis. Luciferase assay was performed to evaluate the interaction between miR-487b and IL-33, and the effects of miR-487b/IL-33-ST2 axis on allergic rhinitis mice were determined by established allergic rhinitis model in mice by ovalbumin (OVA).

Vernal keratoconjunctivitis, a chronic, bilateral, seasonal allergic inflammatory disease of the eye, is an important cause of visual debilitation and impairment of quality of life in children and young adults in certain parts of the world such as the Mediterranean areas, Central and West Africa, the Middle East, Japan, the Indian subcontinent, and South America. It usually has a self-limiting course; however, in a few cases the disease is recurrent and leads to long-term visual disabling complications like keratoconus and limbal stem cell deficiency. The main pathogenic mechanism is IgE mediated; however, there may be non-IgE and certain non-specific hypersensitivity mechanisms. Read More

During the 2000s, Asian sand dust (ASD) was implicated in the increasing prevalence of respiratory disorders, including asthma. We previously demonstrated that a fungus from ASD aerosol exacerbated ovalbumin (OVA)-induced airways inflammation. Exposure to heat-inactivated ASD (H-ASD) and either Zymosan A (ZymA, containing β-glucan) or lipopolysaccharide (LPS) exacerbated allergic airways inflammation in a mouse model, but the effects of co-exposure of LPS and β-glucan are unclear.

Mast cells are key effector cells in inflammatory and allergic immune responses such as asthma, rhinitis, and atopic dermatitis. Activation of mast cells leads to immediate release of preformed mediators such as histamine and proteases, which can regulate vascular permeability and the function of a number of immune and nonimmune cells. Engineered nanomaterials (ENM) have been utilized for a wide range of applications and introduced into a number of consumer products; yet the consequent increase in human exposure and any potential adverse effects have not been fully evaluated.
