EAE Induction by Passive Transfer of MOG-specific CD4+ T Cells.

Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis (MS), which is a chronic inflammatory disease of the central nervous system (CNS). It is characterized by focal demyelination and inflammatory responses mediated by myelin-specific autoreactive CD4+ T cells. Using a passive transfer model of EAE in mice, we have demonstrated that regional specific neural signals by sensory-sympathetic communications create gateways for immune cells at specific blood vessels of the CNS, a phenomenon known as the gateway reflex ( Arima et al., 2012 ; Tracey, 2012; Arima et al., 2013 ; Sabharwal et al., 2014 ; Arima et al., 2015b ). Here we describe protocols for passive transfer model of EAE using freshly isolated (MOG)-specific CD4+ T cells or periodically restimulated MOG-specific CD4+ T cell lines, which are suitable for tracking pathogenic CD4+ T cells in vivo, particularly in the CNS ( Ogura et al., 2008 ; Arima et al., 2012 and 2015b).
