Article Abstract
Background: Little is known about exposure to mouse allergen (Mus m 1) and allergic rhinitis (AR).
Objective: To evaluate the association between mouse allergen exposure and AR in children.
Methods: We examined the relation between mouse allergen level in house dust and AR in 511 children aged 6 to 14 years in San Juan, Puerto Rico. Study participants were chosen from randomly selected households using a multistage probability sample design. The study protocol included questionnaires, allergy skin testing, and collection of blood and dust samples. AR was defined as current rhinitis symptoms and skin test reactivity to at least one allergen.
Results: In the multivariate analyses, mouse allergen level was associated with a 25% decreased odds of AR in participating children (95% confidence interval, 0.62-0.92). Although endotoxin and mouse allergen levels were significantly correlated (r = 0.184, P < .001), the observed inverse association between Mus m 1 and AR was not explained by levels of endotoxin or other markers of microbial or fungal exposure (peptidoglycan and glucan).
Conclusion: Mouse allergen exposure is associated with decreased odds of AR in Puerto Rican school-aged children.

Background And Aim: In animal husbandry, antibiotics are frequently used as growth promoters, as well as for illness prevention and treatment. They are considered important toxic and allergenic contaminants of food and a serious risk factor for the spread of antibiotic resistance. National and international regulatory authorities have established limits on the permissible residue of antibiotics in food.

Background: Midges are widely distributed globally. They can transmit numerous serious diseases as well as trigger an allergic reaction in the host. Their saliva contains a variety of proteins that act as sensitizers to stimulate the host's immune response, leading to IgE-mediated allergic symptoms.

Introduction: The spectrum of eosinophil functions has expanded from fighting helminths to multiple novel roles in malignancy, infection, cancer, and metabolism. In asthma, glucocorticoids, prostaglandins (PG), and cysteinyl-leukotrienes (LT) regulate eosinophil biology through separate signaling pathways. Here we've evaluated the complex interplay between Dexa, PGE2, and CysLTs in eosinopoiesis and eosinophil biology in an allergic asthma model.

Objected: Mal f 1, the first allergen cloned from Malassezia furfur, has been found to have positive IgE reactivity in sera from patients with skin inflammation. In vitro, it has also been shown to induce maturation of dendritic cells and release inflammatory factors. However, its role in skin lipid homeostasis remains largely unexplored.

Streptococcus pneumoniae (SPN) is a significant pathogen causing pneumonia and meningitis, particularly in vulnerable populations like children and the elderly. Available pneumonia vaccines have limitations since they only cover particular serotypes and have high production costs. The emergence of antibiotic-resistant SPN strains further underscores the need for a new, cost-effective, broad-spectrum vaccine.
