MBP and myeloid sarcoma: However, it is plausible that environmental exposure to pathogens which contain molecular mimics to MBP – such as to Herpesviruses – could prime or skew responses to different epitopes with higher potential to cause CNS inflammation leading to MS development; so far there is only sero-epidemiological evidence supporting for a role for EBV in MS and to some extent HHV-6A.
