Expression of keratins, epidermal proteins and inflammatory cells in superficial pemphigus dogs
Superficial pemphigus in dogs is an autoimmune skin disorder. The disease is characterised by the binding of auto-antibodies to desmosomal molecules including desmocollin-1, a major auto-antigen in dogs. However, data on the expression of epidermal proteins in dogs are still limited. Therefore, the...
