After a mean of 80 months since the onset of disease, when evaluated serologically, they had antibodies typical of PV and pemphigoid (Pg). Similarly, 18 patients with bullous pemphigoid (BP) and mucous membrane pemphigoid (MMP) were diagnosed on the basis of histology and immunopathology.After a mean of 60 months since the onset of disease, when their sera were evaluated they were found to have Pg and PV autoantibodies. In both groups of patients the diseases were characterized by a chronic course, which included several relapses and recurrences and were non-responsive to conventional therapy. The major histocompatibility complex class II (MHC II) genes were studied in both groups of patients and phenotypes associated typically with them were observed. Hence, in 33 patients, two different pathogenic autoantibodies were detected simultaneously. The authors provide a computer model to show that each MHC II gene has relevant epitopes that recognize the antigens associated with both diseases. Using the databases in these computer models, the authors present the hypothesis that these two autoantibodies are produced simultaneously due to the phenomena of epitope spreading. eng Relationship between target antigens and major histocompatibility complex (MHC) class II genes in producing two pathogenic antibodies simultaneously journal article URL https://docta.ucm.es/bitstreams/5936d660-417a-4859-8ac1-f45568f53d17/download File MD5 2eef6dd9360332698f749f932ce3605d 456257 application/pdf 40.zakka_etal_CEI_2010.pdf URL https://docta.ucm.es/bitstreams/92403e53-58cf-4b18-8cd0-c8f4f1d8d364/download File MD5 522108377f394c3abc953b37b8122593 72402 text/plain 40.zakka_etal_CEI_2010.pdf.txt
