Description

The skin serves as a physical barrier and an immunological interface that protects the body from the external environment1-3. The aberrant activation of immune cell activity can provoke common skin autoimmune diseases such as psoriasis and vitiligo, which are often characterized by bilateral symmetric lesions at preferred anatomic regions of the body4-9. Understanding what orchestrates patterned cutaneous immune cell activities is necessary for developing effective treatments for these diseases. Here, we identify subsets of dermal fibroblasts responsible for driving patterned autoimmune activity in skin using a robust vitiligo mouse model based on activation of endogenous auto-reactive CD8+ T cells targeting epidermal melanocytes. Through a combination of single-cell transcriptome analysis of patient skin samples, genetic analysis of cell-type-specific knockouts, and engraftment experiments, we find that among multiple IFN-γ-responsive cell types in vitiligo skin, dermal fibroblasts are required to recruit and activate CD8+ cytotoxic T cells through secreted chemokines. Anatomically distinct human dermal fibroblasts exhibit intrinsic differences in chemokine expression in response to IFN-γ. In the mouse model, regional IFN-γ-resistant fibroblasts determine the autoimmune depigmentation pattern in skin. Our study identifies anatomically distinct fibroblasts with permissive or repressive IFN-γ responses as the key driving force that defines body level lesion patterns in vitiligo, and pinpoints mesenchymal subpopulations as novel therapeutic targets for treating autoimmune diseases.
