Under normal conditions (left), melanocytes adhere to laminin-211 in the basement membrane through dystroglycan, maintaining their mature pigment-producing state. In vitiligo (right), remodeling of the basement membrane increases laminin-332 and promotes integrin α3β1-mediated adhesion, activating signalling pathways, including c-Jun, that drive melanocyte dedifferentiation and loss of pigment production.
