    Vitiligo is an autoimmune disorder characterized by CD8+ T cell-mediated destruction of melanocytes, leading to skin depigmentation.

  • 2

    Patients with vitiligo show reduced Treg frequency and impaired function in peripheral blood, contributing to autoimmune responses.

  • 3

    In lesional skin, Treg subsets are significantly decreased, and their function is compromised by a proinflammatory microenvironment.

  • 4

    Therapeutic strategies like NB-UVB, JAK inhibitors, and low-dose IL-2 may help restore Treg function and immune balance in vitiligo.

  • 5

    Understanding Treg dysregulation from blood to skin is crucial for developing effective immunosuppressive therapies for vitiligo.
