multiple sclerosis (ms) is an inflammatory disease of the central nervous system (cns). inflammation caused by immune cells destroy the myelin and then axon. cns failure to complete repair results in permanent disabilities. some types of stem cells have special potentials to repair these injuries and even cure ms. neural crest stem cells with a mutual origin with cns and the ability of differen...

the peak age of onset of inflammatory bowel disease (ibd) is simultaneous with the peak reproductive years. patients have many concerns about the impact of ibd on fertility and pregnancy outcomes. the most important reason for voluntary childlessness is the fear of side effects from medications for ibd. decision making for medical therapy is a complex equation. it is important to summarize avai...

inflammatory bowel disease (ibd) is the term used for a group of diseases with yet unknown etiology, prevalence of which is increasing almost everywhere in the world. the disease was almost non-existent four decades ago in the east, including the middle-east, while now a days it is seen more and more. in addition to the increasing prevalence, our knowledge about its pathogenesis, clinical cours...

background: besides medical therapy, surgical interventions plays an important role in the treatment of inflammatory bowel disease (ibd), but they also involve complications and advantages. this study was undertaken to determine the characteristics and outcome of surgery in patients with ibd. â  methods: all the files of the patients admitted in nemazee and faghihi hospitals with the final diag...

ulcerative colitis and crohn's disease are chronic, relapsing, inflammatory conditions defined by their phenotypic features. family studies have identified a clear genetic influence on disease susceptibility and expression. molecular studies have identified specific genes that predispose individuals to the development of inflammatory bowel disease. some of these genes are specific to either ulc...

Multiple sclerosis is a demyelinating disease associated with an inflammatory immune response in the CNS. Theiler's murine encephalomyelitis virus (TMEV)-induced demyelinating disease is a relevant mouse model for the study of multiple sclerosis. TMEV infection of susceptible mice leads to a persistent virus infection of the CNS which contributes to development of demyelinating disease. We have...

Chronic neurodegenerative diseases such as prion disease and Alzheimer's disease (AD) are reported to be associated with microglial activation and increased brain and serum cytokines and acute-phase proteins (APPs). Unlike AD, prion disease is also associated with a peripheral component in that the presumed causative agent, PrPSc, also accumulates in the spleen and other lymphoreticular organs....

Experimental autoimmune encephalomyelitis (EAE) is a demyelinating disease of the central nervous system (CNS) that is a model for multiple sclerosis. Previously, we showed that depletion of gamma delta T cells significantly reduced clinical and pathological signs of disease, which was associated with reduced expression of IL-1 beta, IL-6, TNF-alpha, and lymphotoxin at disease onset and a more ...

Neuroinflammation is inflammation of the nervous tissue. It be initiated in response to infection, toxic metabolites, auto immunity, traumatic brain injury and variety of causes. Exercise is a promising mechanism of prevention and treatment for disease characterized by neuroinflammation. The benefits of exercise and physical activity (PA) are well known and have effects on function of the centr...

Lesions and neurologic disability in inflammatory CNS diseases such as multiple sclerosis (MS) result from the translocation of leukocytes and humoral factors from the vasculature, first across the endothelial blood-brain barrier (BBB) and then across the astrocytic glia limitans (GL). Factors secreted by reactive astrocytes open the BBB by disrupting endothelial tight junctions (TJs), but the ...
