In adults, the consumer agency investigated the patients who visited the hospital with the immediate hypersensitivity. In this study, the participants were limited to patients who visited the hospital. This made the estimation of the overall prevalence of food allergy in Japan. For children, if we add the questionnaire to the existing study, which questions them regarding the symptoms of food allergy, the diagnosis by the physician, and the blood test, we can better investigate the prevalence of food allergies and changing pattern by the...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
