EAE: imperfect but useful models of multiple sclerosis

Area of Science:

• Neuroimmunology
• Translational Medicine
• Preclinical Research

Background:

• Immunotherapies for multiple sclerosis (MS) exhibit high failure rates in clinical trials.
• This failure is partly due to limitations in current preclinical models, including the use of genetically homogeneous rodents and the experimental autoimmune encephalomyelitis (EAE) model's focus on CD4+ T cells, unlike MS pathology.

Purpose of the Study:

• To discuss advanced preclinical models for multiple sclerosis (MS) research.
• To address the 'immunotherapy gap' by exploring models that better reflect MS pathology and patient genetics.

Main Methods:

• Discussion of preclinical models using humanized rodents and non-human primates.
• Analysis of models that replicate specific aspects of MS pathology.

Main Results:

• Current preclinical models inadequately represent MS, contributing to the immunotherapy gap.
• Humanized rodents and non-human primates offer improved genetic relevance for MS research.

Conclusions:

• Developing more accurate preclinical models is crucial for improving the success rate of MS immunotherapies.
• Utilizing models that better mimic MS pathology can enhance the preclinical selection of effective therapies.
