Psoriasis SCID-mouse model

Psoriasis is characterized by a complex phenotype and pathogenesis along with polygenic determination. Several psoriasis animal models have only been able to incompletely reproduce the disease. A xenogeneic transplantation approach, grafting skin from psoriatic patients onto mice with a severe combined immunodeficiency (SCID), was the first to meet the criteria for a psoriasis model. During the last 10 years, this psoriasis SCID-mouse model not only allowed telling experiments focusing on pathogenetic aspects, but also proved being a powerful tool for drug discovery with a good predictive value.
