Published:November 17, 2021DOI:https://doi.org/10.1016/j.jneuroim.2021.577777

      Highlights

      • Existing methods for the analysis of EAE neuropathology are primarily qualitative.
      • We describe a method for quantitation of a large segment of the EAE spinal cord.
      • This method allows for determination of percent area for many markers of interest.
      • This method will facilitate discovery of medications that protect axons and myelin.

      Abstract

      Multiple sclerosis is an inflammatory and neurodegenerative condition that is frequently modeled using experimental autoimmune encephalomyelitis (EAE). Current methods of EAE histology include imprecise qualitative assessments and time-consuming analyses of selected regions. With increasing interest in neuroprotective or reparative therapies, it is important that potential therapeutics are evaluated in EAE through quantitative neuropathology. We describe a quantitative whole slide imaging immunofluorescence method that allows longitudinal sections of the entire EAE thoracic spinal cord to be investigated for the extent of neuroinflammation, axonal loss, and myelin density. This method should impact MS research by making histological comparisons of EAE increasingly robust.
