Molecular mimicry has been linked to a number of naturally occurring human diseases such as myasthenia gravis (the acetylcholine receptor AChRα-subunit amino acids 160–167 shows cross-reactivity with a shared homologous domain on herpes simplex virus glycoprotein D p286–293) [41] and multiple sclerosis (the myelin basic protein p85–99-specific T cell clones are activated by viral mimicry peptides) [42]. This evidence concerns the gene ACKR1 and myasthenia gravis.
