However, whether this favorable outcome observed in EAE is a consequence of an abrogated neuronal-specific patho- physiological mechanism, is yet to be defined. Here we show that, Cre-loxP-mediated neuron-specific deletion of ngr1 preserved axonal integrity, whereas its re-expression in ngr1؊/؊ female mice potentiated EAE-axonopathy.
