Toleranzinduktion gegen Nickel: Vom Tiermodell zum Menschen

Nickel is the most common contact allergen in humans. Until recently, many questions concerning tolerance mechanisms to nickel were unresolved. Besides human ex vivo, intervention and observation studies, the establishment of a reproducible mouse model has contributed to the analysis of these mechanisms. A more detailed understanding of the pathogenesis of nickel allergy and tolerance towards nickel by investigations in an animal model and in human studies is a prerequisite for developing specific prevention and therapy of nickel allergy. With this article, we provide a review of the investigations concerning nickel allergy and give perspectives towards oral tolerance induction to nickel in the animal model and in humans.
