    Alopecia areata is an autoimmune disorder characterized by hair loss, primarily driven by autoreactive CD8+ T cells.

  • 2

    Single-cell RNA sequencing revealed significant immune niche remodeling in alopecia areata lesions, involving fibroblasts and epithelial cells.

  • 3

    A novel fibroblast subset, FB3, was identified in alopecia areata, characterized by high MIF expression and inflammatory signatures.

  • 4

    The MIF-centered signaling axis was found to connect FB3 fibroblasts with dendritic cell subsets, indicating active immune regulation.

  • 5

    Targeting FB3 differentiation or inhibiting MIF signaling pathways may offer new therapeutic strategies for alopecia areata.
