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 ...
Pemphigoid is a group of rare autoimmune blistering diseases of the skin and mucous membranes.As its name indicates, pemphigoid is similar in general appearance to pemphigus, [1] however unlike pemphigus, pemphigoid does not feature acantholysis, a loss of connections between skin cells.
Circulating auto-antibodies in the human body can target normal parts of the skin leading to disease. This is a list of antigens in the skin that may become targets of circulating auto-antibodies leading to the various types of pemphigoid .
In some cases, these blisters can cover a large area of the skin. [3] Originally, the cause of this disease was unknown, and "pemphigus" was used to refer to any blistering disease of the skin and mucosa. In 1964, researchers found that the blood of patients with pemphigus contained antibodies to the layers of skin that separate to form the ...

Linear IgA bullous dermatosis is a rare immune-mediated blistering skin disease frequently associated with medication exposure, especially vancomycin, with men and women being equally affected. [ 2 ] : 135 It was first described by Tadeusz Chorzelski in 1979 and may be divided into two types: [ 3 ] : 587
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 .
Bullous pemphigoid. Bullous pemphigoid is an autoimmune bullous disease that mainly affects older individuals. Individuals typically present with itchy rashes that transform into fluid filled bullous lesions on the skin. Although these blisters usually appear on the arms, legs, and trunk of the body, they can also be found in the mouth as sores.
