These data of Figure 1 and Figure 2 may potentially demonstrate that anti-MBP, anti-histones and anti-DNA IgGs of MS patients could possess a known phenomenon of partially unspecific complex formation (polyreactivity or polyspecificity) revealed earlier [46,47,48,49], and they recognize all these molecules and hydrolyze them. The gene discussed is MBP; the disease is myeloid sarcoma.
