摘要

Previous studies have shown that vascular endothelial growth factor (VEGF) expression is up-regulated in both multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), a model for MS, and may exacerbate the disease. However, it remains unknown whether anti-VEGF modalities could serve as a potential treatment for such central nervous system (CNS) autoimmune diseases. We constructed a recombinant adenoviral vector carrying FLAG-tagged sFlt-1(1-3) (the first three extracellular domains of Flt-1, the hVEGF receptor-1). Intramuscular transfection of the recombinant adenoviral vector suppressed VEGF-induced inflammatory cell infiltration in matrigel plugs. When given intracerebrally to EAE rats, recombinant sFlt-1(1-3) adenoviral vector significantly reduced disease severity compared to untreated rats. sFlt-1(1-3) gene transfer blocked VEGF and greatly reduced the number of cells that express VEGF and ED1-positive cells in CNS in EAE rats. This study demonstrates that sFlt-1(1-3) gene transfer into the brain ameliorates the severity of EAE by inhibiting monocyte recruitment in the CNS of dark Agouti rats.
