Abstract
- Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the central nervous system (CNS) that can be induced in susceptible mice by the transfer of autoreactive T cells that recognize myelin basic protein (MBP). The onset and subsequent recovery from disease are associated with distinct patterns of cytokine and chemokine expression within the inflammatory lesions of the CNS. Given the likely importance of the local cytokine milieu in regulating the disease process, it would be preferable to administer cytokines locally to the CNS and reduce systemic delivery in order to evaluate their immunoregulatory roles in EAE. For this purpose, we have used retrovirally transduced T cells from MBP-specific T cell receptor transgenic mice in an attempt to target cytokine delivery to the CNS where MBP is primarily expressed. We have found that T cells expressing granulocyte macrophage colony-stimulating factor (GM-CSF) induce severe, chronic EAE from which mice fail to recover. Our results indicate that increased local GM-CSF expression could play an important role in inducing chronic EAE. [Copyright &y& Elsevier]
