Our Myelin Oligodendrocyte Glycoprotein (MOG)-Induced Experimental Autoimmune Encephalomyelitis (EAE) Model

  • Model Description

The MOG-induced EAE model is a pivotal animal model used to study MS. MOG, a member of the immunoglobulin superfamily, is specifically expressed in the CNS on the surface of myelin sheaths and oligodendrocyte processes. This model is induced in female C57BL/6 mice by immunizing them with MOG peptide, followed by pertussis toxin (PTX) injections. The MOG peptide stimulates the proliferation and differentiation of MOG-specific autoimmune T cells, while PTX enhances disease progression by modulating the immune response and aiding the migration of these T cells into the CNS. This model closely mimics the neuroinflammation and demyelination observed in MS, making it an invaluable tool for developing MS therapeutics and studying the immune-mediated mechanisms of the disease.

Characteristics of the MOG-Induced EAE Model in Creative Bioarray

  • Characterized by mononuclear inflammatory infiltration, including macrophages and CD4+ T cells.
  • MOG-induced EAE model is considered the gold standard model and is routinely used in the development of therapeutics for MS.
  • MOG-induced EAE model is a good model of chronic inflammatory demyelination.
  • Available Animal

C57BL/6 mouse (female)

  • Modeling Method

All animals, with the exception of those in the control group, are immunized to induce EAE by receiving a MOG35-55 emulsion through subcutaneous (s.c.) injection on Day 0, accompanied by PTX administered intraperitoneally (i.p.) on both Day 0 and Day 2.
