The development of autoimmune disease is accompanied by the acquired recognition of new self-determinants, a process commonly referred to as determinant spreading. In this study, we addressed the question of whether determinant spreading is pathogenic for progression of chronic-relapsing experimental autoimmune encephalomyelitis (EAE), a disease with many similarities to multiple sclerosis (MS)...

The lipid specificities of two related integral membrane proteins of central nervous system myelin, the proteolipid (PLP) and DM-20 proteins, which differ only by the deletion of a polar stretch of 35 contiguous amino acid residues, were studied with spin-labeled lipids after reconstitution into dimyristoyl-phosphatidylcholine. The selectivity in populating lipid association sites at the protei...

Introduction: Multiple sclerosis (MS) is a common neurodegenerative disease leading to the movement disorder and destruction of myelin. Physical exercise delays the onset of neurodegenerative processes by preventing the destruction of myelin and oligodendrocytes. Therefore, the purpose of this study was to investigate the effect of high-intensity exercise preconditioning on gene expression asso...

Monosymptomatic unilateral optic neuritis is a common first manifestation of multiple sclerosis. Abnormal T cell responses to myelin components including myelin basic protein (MBP), proteolipid protein (PLP), and myelin-associated glycoprotein (MAG) have been implicated in the pathogenesis of multiple sclerosis. Antigen-reactive T helper type 1 (Th1)-like cells that responded by interferon gamm...

Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelinating disease of the central nervous system (CNS) and can be induced by inoculation of animals with homogenized CNS tissue or highly purified myelin proteins such as myelin basic protein (MBP) or proteolipid protein (PLP). It is widely studied as a possible animal model of multiple sclerosis. We performed the present neu...

multiple sclerosis (ms) is an autoimmune disease in which auto-reactive t cells react with self-antigens expressed in the central nervous system (cns). the main cause of ms is unknown. nonetheless, the most probable theory is based on molecular mimicry, which suggests that some infections can activate t cells against brain auto-antigens like myelin proteolipid protein (plp) and initiate the dis...

Oral administration of antigen is a long recognized method of inducing systemic immune tolerance. In animals with experimental autoimmune disease, a major mechanism of oral tolerance triggered by oral administration of antigen involves the induction of regulatory T cells that mediate active suppression by secreting the cytokine TGF-beta 1. Multiple sclerosis (MS) is a presumed T cell-mediated T...

Myelin is a highly specialized membrane unique to the nervous system that ensheaths axons to permit the rapid saltatory conduction of impulses. The elaboration of a compact myelin sheath is disrupted in a diverse spectrum of human disorders, many of which are of unknown etiology. The X chromosome-linked human disorder Pelizaeus-Merzbacher disease is a clinically and pathologically heterogeneous...

Experimental allergic encephalomyelitis (EAE) is an autoimmune disease that can be induced in laboratory animals by immunization with the major myelin proteins, myelin basic protein (MBP) and proteolipid protein (PLP). We analyzed the role of the T cell receptor (TCR) repertoire in susceptibility to EAE induced by these two autoantigens. Autoreactive T cells induced after immunization with MBP ...
