A bioinformatics study conducted in our laboratory, showed that the chaperonin may trigger myasthenia gravis, a diseases of the neuromuscular junction, due the sequence similarity between Hsp60 from two common pathogens, Chlamydia trachomatis and Chlamydia pneumoniae, and the acetylcholine receptor α1 subunit (AChRα1) [109]. This evidence concerns the gene HSPD1 and myasthenia gravis.
