Regional cerebral blood flow (rCBF), regional cerebral glucose metabolic rate (rCMR), and regional pH (r-pH) were measured simultaneously in fulminant acute experimental allergic encephalomyelitis (EAE) by the use of triple-label autoradiography. No changes were found in the absence of lesions (lymphocytic accumulations). In the lesions, rCBF was 79% increased and rCRM was 13% increased, wherea...

Histological and electrophysiological studies were performed on Lewis rats with acute experimental allergic encephalomyelitis (EAE) induced by inoculation with guinea-pig spinal cord and Freund's adjuvants, in order to determine the cause of the neurological signs. These studies demonstrated demyelination-induced nerve conduction block in the large and also the smaller diameter fibres at the ve...

Experimental allergic encephalomyelitis (EAE) was induced in adult Lewis rats with purified guinea pig CNS myelin and Freund's adjuvant. As soon as the very earliest clinical signs appeared the animals were perfused with fixatives and the spinal cord analyzed by electron microscopy, silver methods, and immunocytochemistry. Our findings suggest that in the early stages of EAE a sequence of event...

Experimental allergic encephalomyelitis (EAE) is an autoimmune disease of the central nervous system that serves as a model for the human disease multiple sclerosis. We evaluated rolipram, a type IV phosphodiesterase inhibitor, for its efficacy in preventing EAE in the common marmoset Callithrix jacchus. In a blinded experimental design, clinical signs of EAE developed within 17 days of immuniz...

CD4 T helper precursor cells mature along two alternative pathways, Th1 and Th2. Here we show that these pathways are differentially activated by two costimulatory molecules, B7-1 and B7-2. Using anti-B7 antibodies, this developmental step was manipulated both in vitro and in vivo in experimental allergic encephalomyelitis (EAE). Anti-B7-1 reduced the incidence of disease while anti-B7-2 increa...

An ascending impairment of tail nociception is a previously undescribed clinical sign of acute experimental allergic encephalomyelitis (EAE) in the rat. It occurs in EAE induced by inoculation with purified central nervous system (CNS) myelin basic protein (MBP) as well as with whole spinal cord. It is invariably present and consists of an absence of the vocalization response to noxious mechani...

Multiple sclerosis (MS) is the most common autoimmune demyelinating disease of the central nervous system (CNS). Here, we have explored a novel use of glyceryl tribenzoate (GTB), a flavoring ingredient, in ameliorating the disease process of experimental allergic encephalomyelitis (EAE), an animal model of MS, via TGF-β. Oral feeding of GTB suppressed clinical symptoms of adoptively-transferred...

A number of Ag-specific approaches have been developed that ameliorate experimental allergic encephalomyelitis (EAE), an animal model for the human autoimmune disease multiple sclerosis. Translation to humans, however, remains a consideration, justifying the search for more insight into the mechanism underlying restoration of self-tolerance. Ig-proteolipid protein (PLP) 1 and Ig-myelin oligoden...

Myelinated fibres are characterized by the aggregation of Nav1.6 sodium channels within the axon membrane at nodes of Ranvier, where their presence supports saltatory conduction. In this study, we used immunocytochemical methods to study the organization of sodium channels along axons in experimental allergic encephalomyelitis (EAE), a model of multiple sclerosis. We studied axons within the op...
