Infection has long been suspected as a trigger of autoimmune diseases, and
molecular mimicry mechanism was hypothesized in this study. Microbe originated
peptides were searched from the Uniprot database based on a previous defined
critical amino acid motif within ?3129-150, isoleucine137, tryptophan140,
glycine142, phenylalanine 143 and phenylalanine 145. 23826 microbial peptides
were identified using our searching strategy, among which seven were related with
human infections. Circulating IgG and IgM antibodies against the seven microbial
peptides were detected using ELISA in 76 patients with anti-GBM disease. Four
peptides were recognized by both IgG and IgM antibodies, and one peptide was
recognized by IgG antibodies only. Peptides from Bacteroides, Saccharomyces
cerevisiae, and Bifidobacterium thermophilum possessed the highest recognition
frequency with the prevalence of 73.7%, 61.8% and 67.1% for IgG, 56.6%, 44.7% and
67.1% for IgM in anti-GBM patients. Patients with antibodies against these
microbial peptides showed more severe kidney injury, including higher serum
creatinine and higher percentage of crescent formation. In conclusion, antibodies
against microbial peptides were identified in the circulation of anti-GBM
patients, implying its etiological role in eliciting autoimmune response against
?3(IV)NC1 through molecular mimicry.
