Quantitative analysis of spinal cord neuropathology in experimental autoimmune encephalomyelitis

Wuerch, E;Mishra, M;Melo, H;Ebacher, V;Yong, VW;

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.
