The bullae are formed by an immune reaction, initiated by the formation of IgG [citation needed] autoantibodies targeting dystonin, also called bullous pemphigoid antigen 1, [6] and/or type XVII collagen, also called bullous pemphigoid antigen 2, [7] which is a component of hemidesmosomes. A different form of dystonin is associated with ...

Amyotrophic lateral sclerosis: No consistent evidence of association with autoimmunity. Anti-tubular basement membrane nephritis
Bullous pemphigoid is primarily a disease of older adults and it rarely occurs in children. The vast majority of cases involved individuals between the ages of 60 and 80 years. Two European studies have also suggested the increased risk of bullous pemphigoid with advancing age. [28] [29]

Pemphigus is an autoimmune disease that involves antibodies targeting a protein called desmoglein in the top layer of the skin that holds skin cells together. The proteins are destroyed or disabled by the immune system, leading to the separation of the skin layers, which causes the blisters.
Pemphigoid nodularis is a cutaneous condition that is a variant of bullous pemphigoid that has skin lesions mimicking prurigo nodularis. [ 1 ] The antibody involved is IgG .
