Classic examples are streptococcal antigens and rheumatic fever, or post-streptococcal glomerulonephritis, whereas Epstein-Barr virus (EBV) encoded protein, latent membrane protein 1 (LMP1) and the human protein, myelin basic protein (MBP), have high homology, and this mimicry has been postulated to the basis by which this viral infection can contribute to multiple sclerosis (Gabibov et al. 2011; Sospedra and Martin 2016). The gene discussed is MBP; the disease is rheumatic fever.
