Histological and immunocytochemical studies of human psoriatic lesions transplanted onto SCID mice.
To investigate the pathology of psoriasis, we developed an animal model for this disease using severe combined immunodeficiency (SCID) mice. These mice possess neither B nor T Lymphocytes so that both cellular and humoral immunities are impaired. For the in vivo study of psoriasis, human psoriatic skin was grafted on SCID mice. Long-term morphological and immunohistochemical changes in the grafted skin ware examined for up to 22 weeks after transplantation. The human skin graft were generally well maintained during this period, but the histological and immunohistochemical findings characteristic of psoriasis, except for acanthosis and hyperkeratosis, gradually disappeared as lymphocytic infiltration of the psoriatic lesions declined.
