copyright Illustration Induction des cellules myélinisantes dans le cerveau de souris déficient en myéline après un traitement par l'hormone thyroïdienne T3. Les oligodendrocytes (producteurs de myéline) sont visualisés par une fluorescence verte grâce à un gène marqueur GFP (Green Fluorescent Protein). Des chercheurs ont montré que, dans un modèle animal de la sclérose en plaques (SEP), la remyélinisation des axones est favorisée par un traitement par T3. Cette réparation des gaines de myéline détruites pourrait contribuer au ralentissement ou à la prévention de la sclérose en plaques.
