Outline of Final Research Achievements |
We found that patients with red meat allergy showed prolonged CD203c expression-based basophil activation even if they did not developed allergic reaction. The incidence of red meat allergy is high in Shimane prefecture, as is tick-transmitted Japanese spotted fever. Therefore, we speculated that tick bites may cause these meat allergies. The carbohydrate α-Gal was detected in the salivary gland protein of Haemaphysalis longicornis (H. longicornis), the vector for Japanese spotted fever, by immunoblotting using anti-α-Gal antibody. H. longicornis salivary gland protein-specific IgE was detected in the sera of 24 of 30 patients with red meat allergies. Sensitization to tick salivary gland protein containing α-Gal is possibly a major role in the prolonged CD203c expression-based basophil activation in the patients with red meat allergy.
