El estudio muestra que el sistema de limpieza cerebral se activa y facilita que esos anticuerpos entren y salgan. Para alguien de acá, implica que el cerebro tiene mecanismos de drenaje que podrían ser un blanco de tratamiento, aunque todo se probó en ratones y con un modelo inducido.

How pathogenic autoantibodies enter and are cleared from the brain parenchyma remains poorly understood. The glymphatic system (GS) mediates cerebrospinal fluid (CSF)-interstitial fluid (ISF) exchange and waste removal, yet its role in anti-NMDAR encephalitis is undefined. Methods: We used polypeptides GluN1356-385 induced active-immunization anti-NMDAR encephalitis mouse model. Glymphatic influx and efflux were evaluated via fluorescent tracer delivery combined with real-time imaging and ex-vivo quantification.
