Processionary moths with larvae that carry noxious hairs (setae) are present worldwide. A population of Thaumetopea pinivora (TP) is present at the southern part of Gotland. This larvae has increased in size and become a major concern among people living in or visiting the area. Among persons who stayed in the area during the summer 2005, 20% reported symptoms after contacts with larvae, one third of whom with severe symptoms. The TP larvae carry setae of microscopic size, which can be transferred to humans via air or by direct contact. The skin affected become itching and swelling with redness and blister formation. Inhaled setae may cause asthmatic reactions and oral or nasal contacts may give rhinitis and local inflammation. Severe gastrointestinal distress has been noted after ingestion. On rare occasions, anaphylactic reactions may develop. The mechanisms behind symptoms are only partly known. Acute allergic reactions towards setae associated proteins have been described. These observations suggest that other mechanisms than rapid allergic reactions contribute to the symptoms. Our studies are aimed to elucidate the specific T-cell-mediated immune response, inflammatory reactions and clinical consequences following exposure. The hypothesis that setae and purified setae molecules activate cell-mediated immune and inflammatory reactions is studied.
