Proteolipid Protein (PLP)-Induced Experimental Autoimmune Encephalomyelitis (EAE) Model

Creative Bioarray offers a robust and stable model of Experimental Autoimmune Encephalomyelitis (EAE) induced through Proteolipid Protein (PLP). This model is designed to closely mimic human multiple sclerosis (MS), providing a reliable platform for the evaluation of potential therapeutic interventions. We provide a comprehensive range of assessments and support various administration routes tailored to specific needs, ensuring flexibility and precision in preclinical testing.

Our Proteolipid Protein (PLP)-Induced Experimental Autoimmune Encephalomyelitis (EAE) Model

  • Model Description (Relapsing EAE)

PLP is a major protein component of CNS myelin. Sections of PLP, such as 139-151 peptide, are encephalitogenic to certain mouse strains. The PLP-induced EAE model is commonly used to study MS due to its similarity to the human disease. In this model, female SJL mice are immunized with the PLP139-151 peptide, followed by administration of pertussis toxin (PTX). This leads to a relapsing-remitting disease course characterized by ascending flaccid paralysis, starting from the tail and progressing to hind and forelimb paralysis. The disease involves CNS inflammation, demyelination, and axonal cell death, with autoreactive T cells migrating into and re-activating within the CNS. This model is valuable for studying the effects of potential treatments on disease relapses and overall disease progression.

  • Features of PLP-induced EAE Model in Creative Bioarray
  • Relapsing-Remitting Disease Course: This model is a relapsing-remitting demyelinating disease.
  • Therapeutic Treatment Evaluation: Ideal for studying the development and treatment of EAE relapses.
  • Available Animal

Swiss Jim Lambert (SJL) mouse (female)

  • Modeling Method

Relapsing EAE is induced in female SJL mice by immunization with PLP139-151 in CFA emulsion followed by two-time administration of PTX.

Example Data

Graphs showing the validation of the PLP-EAE model with neurological scores and weight changes over time for CBX-treated and PLP-EAE groups.Fig. 2 Validation of PLP-EAE model. (A) The neurological scores deteriorated quickly at day 8 and entered remission from day 12 to the end of the experiment for CBX-treated groups but increased gradually and were maximum on the last day of the investigation for the PLP-EAE group. (B) Weight gain followed a similar trend with the neurological scores, and the worst day (the maximum weight loss) was observed after the day with top neurological scores. (Ucar et al. 2024)
