Механизмы расследования, лежащие в основе развития симптома паралича в модели MS.

Множественный склероз (MS) — аутоиммунное нейродегенеративное расстройство, при котором около 80% пациентов страдают от боли и 50% — от паралича. Используя модель грызунов для MS, экспериментальный аутоиммунный энцефаломиэлит (EAE), исследователи в основном изучают паралич/моторные заболевания как клинический симптом EAE с меньшим количеством изучения боли MS/EAE. Однако в EAE все мыши испытывают боль как фенотип и только подмножество прогрессирует к параличу. Несмотря на обширные исследования, характеризующие патологию заболеваний, этиология, которая способствует диапазону боли и симптомов мо
