title: Predicting drug hypersensitivity by in vitro tests.
abstract: Recently it was found that drugs causing drug hypersensitivities do not only rely on the formation of hapten-carrier conjugates but can stimulate T cells directly via their T cell receptors for antigen. This new mechanism was termed pharmacological interaction of drugs with immune receptors (p-i concept). It is frequent in systemic drug hypersensitivity reactions and has major implications for predicting them. First experiments to identify such drugs able to interact with T cells are presented.
