Narrow-band UVB irradiation stimulates the migration and functional development of vitiligo-IgG antibodies-treated pigment cells

Abstract

Background  The pathogenesis of vitiligo remains unclear. Most authorities favoured the autoimmune cause for the strong associations of vitiligo with multiple autoimmune diseases and the presence of autoantibodies in vitiligo patients. Narrow-band UVB (NBUVB) irradiation has been considered to be an effective treatment for vitiligo with simple treatment procedure and decreased accumulated ultraviolet exposure doses.


Objectives  The aim this study was to investigate the effects of NBUVB irradiation on normal IgG antibodies (N-IgG) or vitiligo IgG antibodies (V-IgG)-treated NCCmelan5 cells in terms of proliferation, migration and melanin formation.


Methods  Cultured NCCmelan5 cells ...
