Experimental allergic encephalomyelitis (EAE) serves as a model for autoimmune diseases mediated by T lymphocytes. Following sensitization to rat, mouse or guinea pig myelin basic protein (MBP) in complete Freund's adjuvant, inbred mouse strains PL/J (H-2u), SJL/J (H-2s) and (PL/J X SJL/J)F1((PLSJ)F1) develop EAE. Whereas sensitization to the N-terminal 37(More)
Laquinimod is a novel oral drug that is currently being evaluated for the treatment of relapsing-remitting (RR) multiple sclerosis (MS). Using the animal model for multiple sclerosis, experimental autoimmune encephalomyelitis (EAE), we examined how laquinimod promotes immune modulation. Oral laquinimod treatment reversed established RR-EAE and was(More)
In contrast to typical neuroleptic drugs, which have high affinities for dopamine D2 receptors, clozapine binds to multiple neurotransmitter receptors. The mechanisms responsible for its superior clinical efficacy over typical neuroleptics remain unknown. Using an automated genomics approach, total gene expression analysis (TOGA), we found an approximately(More)
The microheterogeneity of myelin basic protein, expressed as the ratio between the least cationic (C-8) charge isomer and the most cationic (C-1), was examined in experimental allergic encephalomyelitis (EAE) cases. These included acute EAE of 2 months' duration induced with bovine proteolipid protein in complete Freund's adjuvant (CFA), chronic EAE induced(More)
OBJECTIVE Aquaporin 4 (AQP4)-specific autoantibodies in neuromyelitis optica (NMO) are immunoglobulin (Ig)G1, a T cell-dependent Ig subclass, indicating that AQP4-specific T cells participate in NMO pathogenesis. Our goal was to identify and characterize AQP4-specific T cells in NMO patients and healthy controls (HC). METHODS Peripheral blood T cells from(More)
Using an automated PCR-based genomics approach, TOtal Gene expression Analysis (TOGA), we have examined gene expression profiles of mouse striatum and frontal cortex in response to clozapine and haloperidol drug treatment. Of 17 315 mRNAs observed, TOGA identified several groups of related molecules that were regulated by drug treatment. The expression of(More)
Memory impairment is a common feature of conditions that involve changes in inflammatory signaling in the brain, including traumatic brain injury, infection, neurodegenerative disorders, and normal aging. However, the causal importance of inflammatory mediators in cognitive impairments in these conditions remains unclear. Here we show that specific immune(More)
Autoantibodies that target the water channel aquaporin-4 (AQP4) in neuromyelitis optica (NMO) are IgG1, a T cell-dependent Ig subclass. However, a role for AQP4-specific T cells in this CNS inflammatory disease is not known. To evaluate their potential role in CNS autoimmunity, we have identified and characterized T cells that respond to AQP4 in C57BL/6 and(More)
Class II-restricted T cell clones specific for myelin basic protein (MBP) have been generated from PL/J and (PL/J X SJL/J)F1 [((PLSJ)F1] mice following sensitization to rat MBP. Of 17 T cell clones generated from (PLSJ)F1 mice, 5 are I-Au(A alpha uA beta u) restricted, one is restricted to I-As(A alpha sA beta s), 10 are restricted to hybrid I-A(u X s)F1 (A(More)
