Research Abstract |
This study revealed that IgG autoantibodies from bullous pemphigoid (BP) patients directly bind with collagen XVII (COL17) on the cell-surface, resulting in dynamic internalization of the complex into the cells. Furthermore, neoepitopes on the shed ectodomain of COL17 were found to be targeted by certain autoantibodies from BP patients. In addition, this study disclosed that migrating keratinocytes directly shed the COL17 which binds with other extracellular matrix proteins including laminin332 and collagen IV.
