| Outline of Final Research Achievements |
It was shown that desmosomal proteins are biochemically associated with lipid rafts on the human keratinocyte cell membrane. Furthermore, lipid rafts are considered to be an significant platform for both assembly and disassembly of desmosomes. It was also demonstrated that anti-desmoglein (Dsg) 3 autoantibodies in the sera of pemphigus vulgaris patients cause clustering of Dsg3 on the cell surface, and the clustered Dsg3 molecules are to be internalized in a both lipid raft-dependent and cellular signaling-dependent manner.
