BACKGROUND Experimental autoimmune encephalomyelitis (EAE) is used as an animal model for human multiple sclerosis (MS), which is an inflammatory demyelinating autoimmune disease of the central nervous system characterized by activation of Th1 and/or Th17 cells. Human autoimmune diseases can be either exacerbated or suppressed by infectious agents. Recent studies have shown that regulatory T ce...

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...

IL-17-producing CD4+ T cells (Th17 cells) have well-described pathogenic roles in tissue inflammation and autoimmune diseases, such as experimental autoimmune encephalomyelitis (EAE); however, the involvement of IL-21 in these processes has remained controversial. While IL-21 is an essential autocrine amplification factor for differentiation of Th17 cells, the loss of IL-21 or IL-21 receptor (I...

Suppression of oxidative injury by viral-mediated transfer of the human catalase gene was tested in the optic nerves of animals with experimental allergic encephalomyelitis (EAE). EAE is an inflammatory autoimmune disorder of primary central nervous system demyelination that has been frequently used as an animal model for the human disease multiple sclerosis (MS). The optic nerve is a frequent ...

Monocyte chemoattractant protein (MCP)-1 plays a critical role in innate immunity by directing the migration of monocytes into inflammatory sites. Recent data indicated a function for this chemokine in adaptive immunity as a regulator of T cell commitment to T helper cell type 2 (Th2) effector function. Studies in a Th1-dependent animal model, experimental autoimmune encephalomyelitis (EAE), sh...

Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis (MS) in which activated T cell and neutrophil interactions lead to neuroinflammation. In this study the expression of CCR6, CXCR2, and CXCR6 in Th17 cells and neutrophils migrating to the brain during EAE was measured, alongside an evaluation of the production of IL-17, IL-23, CCL-20, and CXCL16 in the brai...

Multiple sclerosis (MS) is an inflammatory neurodegenerative disease of the CNS. Recent advances in whole-genome screening tools have enabled discovery of several MS risk genes, the majority of which have known immune-related functions. However, disease heterogeneity and low tissue accessibility hinder functional studies of established MS risk genes. For this reason, the MS model experimental a...

genetic epidemiological studies strongly suggest that additive and interactive genes, each with small effects, mediate the genetic vulnerability for schizophrenia. with the human genome working draft at hand, candidate gene (and ultimately large-scale genome-wide) association studies are gaining renewed interest in the effort to unravel the complex genetics of schizophrenia. linkage and fine ma...

background: several influential factors such as transcription factors and intracellular signaling components are involved in differentiation of stem cells into a specific lineage. p15 and p16 proteins are among these factors. accumulating evidences has introduced the epigenetic as a master regulator of these factors during lineage specification. the main objective of this study is to determine ...
