MOG is a fully relativistic modified theory of gravity based on an action principle. The MOG field equations are exactly solvable numerically in two important cases. In the spherically symmetric, static case of a gravitating mass, the equations also admit an approximate solution that closely resembles the Reissner-Nordström metric. Furthermore, for weak gravitational fields, a Yukawa-type modif...

Using adult male C57BL/6 mice that express a yellow fluorescent protein transgene in their motor neurons, we induced experimental autoimmune encephalomyelitis (EAE) by immunization with myelin oligodendrocyte glycoprotein peptide 35-55 (MOG peptide) in complete Freund's adjuvant (CFA). Control mice of the same transgenic strain received CFA without MOG peptide. Early in the course of their illn...

Tyrosine kinase 2 (Tyk2), a member of the JAK family, is involved in IL-12- and IL-23-mediated signaling. In the present study, we examined the roles of Tyk2 in the development of myelin oligodendrocyte glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE) by using Tyk2 knockout (KO) mice. In vitro differentiation of Th1 but not Th17 cells was severely impaired in Tyk2 KO C...

CD4+ Th17 cells are believed to play an important role in the development of a variety of autoimmune diseases including EAE, an animal model of MS. Previously, we and others demonstrated that LXR agonists suppressed the activation of primary glial cells and blocked the development of EAE. The present studies demonstrated that the LXR agonist T0901317 suppressed IL-17A expression from splenocyte...

Myelin oligodendrocyte glycoprotein (MOG)-associated disease is an autoimmune of the central nervous system, associated with presence immunoglobulin G serum antibodies against MOG. Recent data have allowed characterization clinical spectrum MOG-associated disease, which now considered a new entity, distinct from multiple sclerosis and neuromyelitis optica disorders. Optic neuritis most common p...

The role of processing in antigen (Ag) presentation and T cell activation in experimental allergic encephalomyelitis (EAE) was evaluated in wild-type mice, mice that selectively express either Ii p31 or p41, and mice completely deficient in Ii or H-2M. We demonstrate that processing of myelin oligodendrocyte glycoprotein (MOG) is required for presentation of the dominant encephalitogenic MOG ep...

While neuromyelitis optica (NMO) immunoglobulin (Ig) G is considered the hallmark serologic marker of NMO, its association is not absolute, as NMO IgG is not detected in approximately one-fourth of the patients diagnosed with NMO spectrum disorder (NMOSD). Thus, the recent discovery that antibodies to myelin oligodendrocyte glycoprotein (MOG) are detected in some NMO IgG-seronegative patients m...

Seed size is one of the most important traits in leguminous crops. We obtained a recessive mutant of blackgram that had greatly enlarged leaves, stems and seeds. The mutant produced 100% bigger leaves, 50% more biomass and 70% larger seeds though it produced 40% less number of seeds. We designated the mutant as multiple-organ-gigantism (mog) and found the mog phenotype was due to increase in ce...

Semliki Forest Virus (SFV) induces an encephalomyelitis followed by demyelination in the brains of C57Bl6/J (B6) mice. To investigate the role of molecular mimicry in the pathogenesis of postviral demyelination, alignment algorithms were used and amino acid homologies between immunogenic epitopes of SFV and myelin autoantigens, myelin basic protein (MBP), myelin proteolipid protein (PLP) and my...

Multiple sclerosis (MS) lesions are characterized by inflammatory demyelination and reactive gliosis, and although remyelination occurs in some lesions it is limited and incomplete. Leukemia inhibitory factor (LIF) is an important cytokine that stimulates oligodendrocyte proliferation and survival in vitro. Opalin is a unique molecular marker for mature oligodendrocytes. The aim of this study w...
