Identification of a novel non-desmoglein autoantigen in Pemphigus Vulgaris

Di Lullo, Giulia ; Calabresi, Valentina ; Mariotti, Feliciana ; Zambruno, Giovanna ; Lanzavecchia, Antonio ; Di Zenzo, Giovanni

In: Frontiers in immunology, 2019, vol. 10, p. 1391

Pemphigus vulgaris (PV) is an autoimmune bullous disease of the skin and mucous membranes characterized by the presence of circulating and tissue-bound autoantibodies against keratinocyte cell surface antigens, specifically desmoglein (Dsg) 1 and 3. The pathogenic role of anti-Dsg antibodies is well-established, while the mechanism of blister formation is only partly defined. We have applied...

Pemphigus autoantibodies generated through somatic mutations target the desmoglein-3 cis-interface

Di Zenzo, Giovanni ; Di Lullo, Giulia ; Corti, Davide ; Calabresi, Valentina ; Sinistro, Anna ; Vanzetta, Fabrizia ; Didona, Biagio ; Cianchini, Giuseppe ; Hertl, Michael ; Eming, Rudiger ; Amagai, Masayuki ; Ohyama, Bungo ; Hashimoto, Takashi ; Sloostra, Jerry ; Sallusto, Federica ; Zambruno, Giovanna ; Lanzavecchia, Antonio

Pemphigus vulgaris (PV) is an autoimmune blistering disease of skin and mucous membranes caused by autoantibodies to the desmoglein (DSG) family proteins DSG3 and DSG1, leading to loss of keratinocyte cell adhesion. To learn more about pathogenic PV autoantibodies, we isolated 15 IgG antibodies specific for DSG3 from 2 PV patients. Three antibodies disrupted keratinocyte monolayers in vitro,...
