Melanocyte regeneration in vitiligo requires WNT beneath their wings
Melanocytes in patients with vitiligo possess intrinsic abnormalities that contribute to its pathogenesis. Regazzetti et al. report that CXCL10 expression reflects subtle inflammation in normal-appearing skin but not in stable depigmented lesions, supporting the hypothesis that melanocytes themselves initiate autoimmune inflammation prior to clinically evident disease. In addition, they find th...
متن کاملInterleukin 1-α: A Modulator of Melanocyte Homeostasis in Vitiligo
Background: Vitiligo is a hypomelanotic autoimmune skin disorder arising from a breakdown in immunological self-tolerance, which leads to aberrant immune responses against melanocytes leading to selective destruction of melanocytes. High levels of Interleukin 1(IL1) have been reported in various autoimmune disorders including vitiligo. The aim of present study was to explore the effect of IL1-α...
متن کاملCD4 T cell-dependent autoimmunity against a melanocyte neoantigen induces spontaneous vitiligo and depends upon Fas-Fas ligand interactions.
Better understanding of tolerance and autoimmunity toward melanocyte-specific Ags is needed to develop effective treatment for vitiligo and malignant melanoma; yet, a systematic assessment of these mechanisms has been hampered by the difficulty in tracking autoreactive T cells. To address this issue, we have generated transgenic mice that express hen egg lysozyme as a melanocyte-specific neoant...
متن کاملInteractions between growth hormone, insulin-like growth factor I, and basic fibroblast growth factor in melanocyte growth.
Melanocytes, highly differentiated neural crest-derived cells, are located in the basal layer of the epidermis, where they play a role in protecting against UV damage in the skin. Previous studies suggest that both growth hormone (GH) and the insulin-like growth factor I (GH/IGF-I) system may be important for melanocyte growth and function. We have therefore characterized the role of the GH/IGF...
متن کاملTenascin is overexpressed in vitiligo lesional skin and inhibits melanocyte adhesion.
The aetiology of vitiligo remains obscure. In this study, the role of integrins in the observed inability of melanocytes to repopulate lesional skin was investigated. Antibodies directed to alpha 2, alpha 3, alpha 5, alpha v, alpha 6, beta 1 and beta 3 integrin subunits were used. Immunohistology revealed no marked differences in the overall levels of expression of integrins between control, no...
