This article details the materials and methods required for both active induction and adoptive transfer of experimental autoimmune encephalomyelitis (EAE) in the SJL mouse strain using intact proteins or peptides from the two major myelin proteins: proteolipid protein (PLP) and myelin basic protein (MBP). Additionally, active induction of EAE in the C57BL/6 strain using myelin oligodendrocyte glycoprotein (MOG) peptide is also discussed. Detailed materials and methods required for the purification of both PLP and MBP are described, and a protocol for isolating CNS-infiltrating lymphocytes in EAE mice is included.

Experimental autoimmune encephalomyelitis is a CD4 T cell-mediated demyelinating disease of the CNS that serves as a model for multiple sclerosis. Cytokines and chemokines shape Th1 and Th17 effector responses as well as regulate migration of leukocytes to the CNS during disease. The CNS cellular infiltrate consists of Ag-specific and nonspecific CD4 and CD8 T cells, neutrophils, B cells, monocytes, macrophages, and dendritic cells.

Article Synopsis
  • There are no typical lymphatic vessels in the central nervous system (CNS), but nearby lymphatics might help with fluid balance and immune monitoring.
  • During neuroinflammation, specifically in experimental autoimmune encephalomyelitis (EAE), lymphatic vessels near the cribriform plate show growth (lymphangiogenesis) that relies on VEGFC and VEGFR3 and help drain cerebrospinal fluid (CSF) and cells from the CNS.
  • This lymphangiogenesis aids in the removal of CNS-derived antigens, leading to T cell activation in nearby lymph nodes, while meningeal lymphatics show no such growth, indicating a difference in lymphatic responses within the CNS.

Experimental autoimmune encephalomyelitis (EAE) is a CD4 T cell-mediated demyelinating disease of the central nervous system (CNS) where macrophages are the end-stage effector cell. EAE serves as a model for multiple sclerosis where it has been instructive in delineating the autoimmune cellular response in the CNS for the purpose of developing more effective therapies. Understanding the nature of how cytokine and chemokine networks regulate the migration of leukocytes to the CNS requires the ability to track subpopulations of those cells in vivo.
