Abstract

Analysis of gene expression from cutaneous lupus erythematosus, psoriasis, atopic dermatitis, and systemic sclerosis using gene set variation analysis (GSVA) revealed that lesional samples from each condition had unique features, but all four diseases displayed common enrichment in multiple inflammatory signatures. These findings were confirmed by both classification and regression tree analysis and machine learning (ML) models. Nonlesional samples from each disease also differed from normal samples and each other by ML. Notably, the features used in classification of nonlesional disease were more distinct than their lesional counterparts, and GSVA confirmed unique features of nonlesional disease. These data show that lesional and nonlesional skin samples from inflammatory skin diseases have unique profiles of gene expression abnormalities, especially in nonlesional skin, and suggest a model in which disease-specific abnormalities in “prelesional” skin may permit environmental stimuli to trigger inflammatory responses leading to both the unique and shared manifestations of each disease.

  • Analysis of lesional and nonlesional skin samples from CLE, psoriasis, AD, and SSc revealed shared inflammatory profiles (eg, IFN, IL-12 complex) that distinguish from control skin as well as disease-specific features (eg, lack of IL-21 complex signature and increased TGFβ fibroblast signature in SSc).

    “Martínez et al (2022) analyzed lesional and nonlesional skin samples from various inflammatory skin diseases (CLE, psoriasis, AD, and SSc), revealing shared inflammatory profiles (eg, IFN, IL-12 complex) that distinguish from control skin as well as distinguishing features specific for each disease (eg, lack of IL-21 complex signature and increased TGFβ fibroblast signature in SSc).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
