描述 | Laquinimod is a potent immunomodulator which prevents neurodegeneration and inflammation in the central nervous system. In vivo laquinimod treatment inhibited donor myelin-specific T cells from transferring EAE (experimental autoimmune encephalomyelitis) to naive recipient mice. In vivo laquinimod treatment altered subpopulations of myeloid antigen presenting cells (APC) that included a decrease in CD11c(+)CD11b(+)CD4(+) dendritic cells (DC) and an elevation of CD11b(hi)Gr1(hi) monocytes[3]. Topical administration of laquinimod to the injured corneas dramatically inhibited alkali-induced corneal neovascularization and decreased inflammatory cell (such as macrophage) infiltration in a corneal injury mouse model. Laquinimod significantly downregulated the expression of chemokines (monocyte chemotactic protein-1 and macrophage inflammatory protein-1), pro-inflammatory cytokines (interleukin-1β and tumor necrosis factor-alpha), vascular endothelial growth factor, nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 and apoptosis-associated speck-like protein containing C-terminal caspase-recruitment domain adaptor protein in both injured corneas and RAW cells. In vitro, laquinimod also dramatically inhibited the proliferation, migration and tube formation of human umbilical vein endothelial cells[4]. Laquinimod had a significant protective impact against MPP+-induced neurotoxicity. Laquinimod prevented MPP+-induced reduction of cell proliferation, the release of lactate dehydrogenase (LDH), and apoptosis[5]. Laquinimod protects against glutamate excitotoxicity of the cerebellum of EAE mice by bursting the expression of glial glutamate transporters, independently of its anti-inflammatory effects[6]. |
