Electrophilicity is one of the most common features of skin contact sensitizers and is necessary for protein haptenation. The Keap1 (Kelch-like ECH-associated protein 1)/Nrf2 -signaling pathway is dedicated to the detection of electrophilic stress in cells leading to the upregulation

Hydroxycitronellal, an important ingredient in fragrances, was studied for its sensitizing potential in human skin. Fifteen human maximization tests were conducted with hydroxycitronellal obtained from four different sources at induction concentrations from 5 to 12%. No reactions were induced at

A multi-dose-response induction protocol for the guinea pig maximization test (GPMT), including a statistical computer program, has earlier been developed to improve the power of predictive tests for identification of contact allergens. This dose-response protocol, with 2 modifications (i.e., increased

The choice of vehicle for patch test materials is important for the bioavailability and stability of the allergens. Examples are given from the standardization of the TRUE Test and include caine mix, Kathon CG, and fragrance mix.

A critical step in the induction of allergic contact dermatitis is the interaction of haptens with immature dendritic cells (iDC) leading to their activation. Therefore iDC appear as suitable targets for the evaluation of the sensitizing properties of haptens with
