MDP-CFA-Induced EAE

Multiple Sclerosis Model 

Self-remitting myelin basic protein (MBP) induced EAE Efficacy Model for Multiple Sclerosis (MS)

When conducting MS research, it has been found that one dose of MPB in a Lewis rat leads to a single relapse that's characterized mainly by hind paw paralysis. And on the histology level, such a model can be characterized by infiltration of mononuclear cells to the cervical spinal cord and formation of foci. Unfortunately, this model can be self-limiting and does not show demyelination.

MDP-induced EAE Efficacy Model at MD Biosciences subjects Lewis rats to an MBP (emulsified with CFA) injection on day 0, where the disease develops between days 10-13, and fully disease recovery occurs between day 18-21. 

Model Assessments Include:

  • Clinical score
  • Biomarkers
  • Histology for cellular infiltration
  • Immunohistochemistry (IHC)
  • PK

Brain tissue - H&E Staining

MD Biosciences offers H&E staining of brain tissue for detection of inflammatory cells infiltrating into the spinal cord.
