An animal model for chronic meningeal inflammation and inflammatory demyelination of the cerebral cortex

ABSTRACT: Modelling chronic cortical demyelination allows to study long-lasting pathological changes ob-served in multiple sclerosis such as failure of remyelination, chronically disturbed functions of oligodendrocytes, neurons and astrocytes, brain atrophy and cognitive impairments. We aimed at generating an animal model for studying the consequences of chronic cortical demyelination and meningeal inflammation. To induce long-lasting cortical demyelination and chronic meningeal inflammation, we immunized female Lewis rats against myelin oligodendrocyte glycoprotein (MOG) and injected lentiviruses for continuing overexpression of the cytokines TNFα and IFNγ in the cortical brain parenchyma. Immunization with MOG and overexpression of TNF and IFN led to widespread subpial demyelination and meningea
