Aetiopathogenesis of Vitiligo

Area of Science:

• Dermatology
• Immunology
• Autoimmune Diseases

Background:

• Vitiligo is a chronic autoimmune condition causing skin depigmentation via melanocyte loss.
• Research is actively clarifying the complex cellular interactions driving vitiligo pathogenesis.
• Recent findings emphasize the role of resident T memory cells in lesion development and recurrence.

Purpose of the Study:

• To review the mechanisms of melanocyte loss in vitiligo.
• To highlight the intercellular communication networks involved in vitiligo.
• To focus on the immune response activation in skin lesions.

Main Methods:

• This is a narrative review.
• It synthesizes current research on vitiligo pathophysiology.
• Focuses on cell-cell interactions and immune responses.

Main Results:

• Complex interactions between epidermal cells, fibroblasts, and immune cells contribute to melanocyte loss.
• Resident T memory cells are crucial in vitiligo lesion development and recurrence.
• Understanding these interactions opens new therapeutic avenues.

Conclusions:

• A deeper comprehension of the cellular crosstalk in vitiligo is advancing therapeutic strategies.
• Targeting the local skin immune response may offer new treatment options for vitiligo.
