Abstract
Anisakis (Anisakidae) is one of the most important causes of helminth-induced allergic reactions and elicits clinical responses that include urticaria, rhinitis, bronco-constriction, cough, and/or gastrointestinal symptoms. More than 13 reactive allergens have been identified in the serum of Anisakis allergy patients, but the allergenicity of only a few of these have been evaluated in vivo using a mouse model. To evaluate the allergenicity of two important allergens, Ani s 1 and Ani s 9, we induced experimental allergic airway inflammation in a mouse model by repeated intranasal administration of the allergens. Both recombinant proteins (rAni s 1 and rAni s 9) elicited increased airway hyperresponsivity, airway infiltration by inflammatory cells (especially eosinophils), bronchial epithelial cell hyperplasia, all of which are characteristic of allergic airway inflammation. These allergens significantly increased the levels of Th2-related cytokines (IL-4, IL-5, IL-13, and IL-25) and Th17 related cytokines (IL-6 and IL-17) in both splenocytes and airway (except IL-17 in airway by rAni s 9). OVA-specific IgE and total IgE were increased in rAni s 1 and rAni s 9 treated mice as compared with controls treated with OVA alone. In addition, these two allergens induced gene expression of thymic stromal lymphopoietin (TSLP) and IL-25 (initiators of the Th2 response), as well as CXCL1 (initiator of the Th17 response) in mouse lung epithelial cells. In conclusion, repeated intranasal treatments with rAni s 1 and rAni s 9 induced airway inflammation in mice by elevating of Th2 and Th17 responses in the lung.
