Tissue type plasminogen activator (t-PA) has been implicated in the development of multiple sclerosis (MS) and in rodent models of experimental autoimmune encephalomyelitis (EAE). We show that levels of t-PA mRNA and activity are increased ~4 fold in the spinal cords of wild-type mice that are mice subjected to EAE. This was also accompanied with a significant increase in the levels of pro-matr...

multiple sclerosis (ms) is an autoimmune disease, which is characterized by demyelination and neuroinflammation. extracellular matrix (ecm) have important role in the central nervous system (cns). alterations are happening to the ecm after the cns disorder like ms, alzheimer and other neural injury. tenasin-c (tnc) is a glycoprotein that is highly expressed in inflammatory conditions of the cns...

Extracellular adenosine has an important role in regulating the severity of inflammation during an immune response. Although there are four adenosine receptor (AR) subtypes, the A2AAR is both highly expressed on lymphocytes and known as a prime mediator of adenosine's anti-inflammatory effects. To define the importance of A2AAR signaling during neuroinflammatory disease progression, we used the...

CD73 is a cell surface enzyme of the purine catabolic pathway that catalyzes the breakdown of AMP to adenosine. Because of the strong immunosuppressive and antiinflammatory properties of adenosine, we predicted that cd73(-/-) mice would develop severe experimental autoimmune encephalomyelitis (EAE), an animal model for the central nervous system (CNS) inflammatory disease, multiple sclerosis. S...

To elucidate the role of nitric oxide synthase (NOS) in the pathogenesis of experimental autoimmune encephalomyelitis (EAE), we analyzed the expression of constitutive neuronal NOS (nNOS), endothelial NOS (eNOS), and inducible NOS (iNOS) in the spinal cords of rats with EAE. We further examined the structural interaction between apoptotic cells and spinal cord cells including neurons and astroc...

Bakground: Multiple sclerosis (MS) is a CD4+ T cell-mediated autoimmune disease affecting the central nervous system (CNS). It was previously believed that Th1 cells were pathogenic T cells in experimental autoimmune encephalomyelitis (EAE). However, the functional role of Th1 cells in EAE has been reconsidered upon the discovery of IL-17- producing T cells which are consider as dominant effect...

The spinal cord is a target of progesterone (PROG), as demonstrated by the expression of intracellular and membrane PROG receptors and by its myelinating and neuroprotective effects in trauma and neurodegeneration. Here we studied PROG effects in mice with experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis characterized by demyelination and immune cell infiltration i...

The effect of intranasal (IN) administration of Semliki Forest virus (SFV) recombinant particles expressing interferon-β [IFN-β, a partially effective treatment for multiple sclerosis (MS)] on the progression of experimental autoimmune encephalomyelitis (EAE, a murine model for MS) was investigated. The murine IFN-β gene was cloned from SFV-infected mouse brain by RT-PCR into an SFV-enhanced ex...

The objective of this study was to detect interleukin-17 (IL-17), interferon-gamma (IFN-gamma), interleukin-4 (IL-4) and forkhead/winged helix transcription factor p3 (Foxp3) protein and gene expression of the optic nerve and to further explore the role of T helper cell subsets such as Th1, Th2, Th17 and Treg in the pathogenesis of optic neuritis in experimental autoimmune encephalomyelitis (EA...

Interleukin (IL)-16, a CD4+ immune cell specific chemoattractant cytokine, has been shown to be involved in the development of multiple sclerosis, an inflammatory demyelinating disease central nervous system (CNS). While cells such as T and macrophages are reported producers IL-16, cellular source IL-16 CNS is less clear. This study investigates correlation expression levels with severity neuro...
