Abstract

To determine if whole-body irradiation with ultraviolet light can induce immune complex formation both in skin and in circulation, NZB W F1 mice with high serum titers of anti-nuclear antibodies (ANA) and anti-DNA antibodies were submitted to prolonged uv irradiation. Skin biopsies and serum samples collected at different times after uv exposure showed a high incidence of ANA binding to epidermal cell nuclei and decreased serum DNA binding activity, suggesting that circulating DNA-anti DNA immune complexes had formed. This interpretation was supported by the observation that treatment of the postirradiation sera with DNase partially restored their DNA binding activity.
