The main objectives of the study are: To determine if RNA recovery from tape harvesting allows for the identification of a disease gene signature (e.g., interferon \[IFN\] signature for lupus) or other biomarkers that may differentiate affected from normal or unaffected skin; To determine if the lupus gene signature is differentially expressed in the epidermis from active discoid lupus erythematosus (DLE) or subacute cutaneous lupus erythematosus (SCLE) lesions when compared with unaffected skin from the same participants and from the skin of healthy volunteers (HVs); To determine if the atopic dermatitis (AD) gene signature is differentially expressed in the epidermis from active AD lesions when compared with unaffected skin from the same participants and from the skin of HVs; and To correlate the levels of transcripts of targeted genes in the skin by tape harvesting with those obtained from the blood.
