Gene expression time-course in the human skin during elicitation of allergic contact dermatitis

Genes involved in the inflammatory response resulting in allergic contact dermatitis (ACD) are only partly known. In this study, we introduce the use of high density oligonucleotide arrays for gene expression profiling in human skin during the elicitation of ACD. Skin biopsies from normal and nickel-exposed skin were obtained from 7 nickel-allergic patients and 5 non-allergic controls at four different time points during elicitation of eczema: 0h, 7h, 48h and 96h. Each gene expression profile was analysed by hybridization to high density oligonucletide arrays.
