Bullous Pemphigoid is characterized by autoantibodies targeting two hemidesmosomal proteins: BP180 (also known as Type XVII collagen) and BP230 (a plakin family protein, plectin). Desmoglein 1 and 3 are the target antigens in Pemphigus Vulgaris. Collagen VII is the target antigen in Epidermolysis Bullosa Acquisita. Transglutaminase (specifically tissue transglutaminase) is the autoantigen in Dermatitis Herpetiformis and Celiac Disease.
