MOG-induced EAE Efficacy Model for MS Research
Experimental autoimmune encephalomyelitis (EAE) is primarily used as a non-clinical model of autoimmune inflammatory diseases of the CNS, and resembles many aspects of human Multiple Sclerosis (MS). The myelin oligodendrocyte glycoprotein (MOG)-induced EAE model is ideal for exploring this immune-mediated mechanism of neuroinflammation and demyelination. Our MOG-induced EAE model is well-characterized and commonly used in the development of a variety of MS therapeutics. MDB also provides OECD GLP-certified clinical batch release testing services for Copaxone® generics (Glatiramer Acetate).
At MD Biosciences, the Multiple Sclerosis efficacy model contains immunization with Myelin Oligodendrocyte Glycoprotein (MOG35-55), which induces a chronic form of EAE in mice.
-
Characteristics of the MOG-EAE model
- Mononuclear inflammatory infiltration (macrophages, CD4+ T cells)
- Demyelination in the peripheral white matter of the spinal cord, which leads to gradual loss of motor function
- Meningitis and perivascular inflammatory cuffing in the cerebellum and hindbrain white matter
- This model has a reduced tendency to resolve inflammation and demyelination after the peak of disease, making it a good model of chronic inflammatory demyelination.

Assessments
Inflammatory biomarkers provide information related to mechanisms contributing to inflammatory pain and how well compounds modulate the inflammatory and/or pain response.
Behavior
Pain behavior tests assess the response to various pain stimuli.
Biomarkers
Evaluate pro-inflammatory and anti-inflammatory biomarkers from samples.
Histology
IHC and histological staining to evaluate inflammatory markers in tissue samples.
Electrophysiology
Evaluate spontaneous nerve firing using in vivo electrophysiology.
Scientific Data
Cytokines by multiplex analysis. Two markers from a cytokine profile in MOG-induced animals that were treated with vehicle or positive control. Day 15 was compared to day 26.
