Research Expertise
Professor Hörauf is internationally renowned for his work in Tropical Medicine, specifically, for pioneering a new drug treatment for filariasis (a group of neglected tropical diseases). The new treatment exploits an endosymbiosis between the worms and bacterial endosymbionts called Wolbachia, which are susceptible to some classes of antibiotic. Prof. Hörauf’s group was the first to characterize a TLR2 ligand from Wolbachia, and established that blindness brought about by filarial antigens as the worm larvae migrate into the eye in onchocerciasis (or “river blindness”) is dependent on Wolbachia, and again mediated by the innate immune system. Prof. Hörauf’s second focus is in the field of infection immunity, where his group were the first to detect regulatory T cells in humans in an infection. Education / Training

Iodine excess and hyperthyroidism

150 m g iodine are daily required for thyroid hormone synthesis. The thyroid gland has intrinsic mechanismsthat maintain normal thyroid function even in the presence of iodine excess. Large quantities of iodide are pres-ent in drugs, antiseptics, contrast media and food preservatives. Iodine induced hyperthyroidism is frequentlyobserved in patients affected by euthyroid iodine deficient goiter wh
