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 ...
PF in animals produces clusters of small vesicles that quickly evolve into pustules. Pustules may rupture, forming erosions or become crusted. Left untreated, PF in animals is life-threatening, leading to not only loss of condition, but also secondary infection. PV is a very rare disorder described in pet dogs and cats.
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.
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

The number of target antigens varies on a case by case basis. The variability is likely what accounts for the different presentations of PNP. Through immunoprecipitation, target antigens have been found to include desmoglein-3, desmoglein-1, envoplakin, periplakin, desmoplakin 1, desmoplakin 2, and bullous pemphigoid antigen I.

Pemphigus foliaceus is an autoimmune blistering disease of the skin. [1] Pemphigus foliaceus causes a characteristic inflammatory attack at the subcorneal layer of epidermis, which results in skin lesions that are scaly or crusted erosions with an erythematous (red) base. [2]
