Project description:

Role of Regulatory T cells in B cell-mediated Autoimmune Skin Disease
Autoimmune bullous dermatoses (AIBD) are severe autoantibody-mediated diseases of skin and mucous membranes. Present autoantibodies against structural proteins of desmosomes and hemidesmosomes lead to the recruitment and activation of immune cells which results in the formation of blisters between epidermis and dermis. Regarding the specificity of each autoantibody we can distinguish between different subforms of AIBDs, like bullous pemphigoid and pemphigus. So far, the exact pathomechanism of certain autoantibodies in AIBDs is not well understood.
We work in our group with a mouse model called Scurfy, where the affected mice spontaneously develop skin blistered caused by different autoantibodies with different specificities. The aim of this project is the investigation of the pathomechanism of different autoreactive autoantibodies in the setting of AIBD. Furthermore, the role of T follicular helper cells (Tfh) and follicular regulatory T cells (Tfr) for the induction of autoantibodies will be investigated by using different established mouse models.
