Experimental encephalomyelitis at age 90, still relevant and elucidating how viruses trigger disease, 2023, Lawrence Steinman

20 yr ago, a tribute appeared in this journal on the 70th anniversary of an animal model of disseminated encephalomyelitis, abbreviated EAE for experimental autoimmune encephalomyelitis. “Observations on Attempts to Produce Disseminated Encephalomyelitis in Monkeys” appeared in the Journal of Experimental Medicine on February 21, 1933. Rivers and colleagues were trying to understand what caused neurological reactions to viral infections like smallpox, vaccinia, and measles, and what triggered rare instances of encephalomyelitis to smallpox vaccines. The animal model known as EAE continues to display its remarkable utility.

Recent research, since the 70th-anniversary tribute, helps explain how Epstein–Barr virus triggers multiple sclerosis via molecular mimicry to a protein known as GlialCAM. Proteins with multiple domains similar to GlialCAM, tenascin, neuregulin, contactin, and protease kinase C inhibitors are present in the poxvirus family. These observations take us a full circle back to Rivers’ first paper on EAE, 90 yrs ago.

I think one could also make a case for EAE being inhumane and having not made much difference to the development of understanding of MS. I have never been sure what it told us if anything. It is pretty cruel.
