MOG and myeloid sarcoma: For example, C57BL/6 mice can be immunized with myelin OL glycoprotein peptide 35‐55 (MOG‐peptide35‐55) to elicit an acute neuroinflammatory infiltration followed by progressive neurodegeneration,[19] mimicking chronic progressive MS patients whereas SJL mice that are immunized with proteolipid protein peptide139‐151 (PLP‐peptide139‐151) elicit a course resembling relapsing‐remitting MS, the most common form of MS.
