Background : Exercise training induces beneficial effects on neurodegenerative diseases, and specifically multiple sclerosis (MS) it’s model experimental autoimmune encephalomyelitis (EAE). However, it is unclear whether exercise exerts direct protective the central nervous system (CNS), nor are mechanisms of neuroprotection fully understood. In this study, we investigated neuroprotective high-...

objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...

introduction: antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. these peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. therefore, the modulatory effects of brevinin-2r, an antimicrobial peptide extracted from the skin of the frog (rana ridibunda), w...

BACKGROUND Multiple microarray analyses of multiple sclerosis (MS) and its experimental models have been published in the last years. OBJECTIVE Meta-analyses integrate the information from multiple studies and are suggested to be a powerful approach in detecting highly relevant and commonly affected pathways. DATA SOURCES ArrayExpress, Gene Expression Omnibus and PubMed databases were scree...

The production of a characteristic intestinal histopathology called attaching and effacing (A/E) lesions by enteropathogenic Escherichia coli (EPEC) is a major characteristic of EPEC pathogenesis. We previously identified a chromosomal gene (eae) of EPEC necessary for the production of A/E lesions on human tissue culture cells. Using antiserum raised to an Eae-PhoA fusion protein, we found that...

Experimental allergic encephalomyelitis (EAE) is an autoimmune disease of the central nervous system with many similarities to multiple sclerosis. The main effector cells involved are CD4+ T cells, recognizing encephalitogenic epitopes within the central nervous system, and macrophages, both of which secrete proinflammatory cytokines, such as IFN-gamma and TNF. Studies have shown that immunomod...

background: ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. this study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (figla), growth differentiation factor-9 (gdf-9), follicle-stimulating hormone receptor (fshr), and kit ligand after v...

T cells infiltrating the iris/ciliary body of Lewis rats with anterior uveitis (AU) that had been induced by myelin basic protein (MBP) immunization were previously found to share surface markers common to the T cells that cause experimental autoimmune encephalomyelitis (EAE). To determine whether these AU-associated T cells are in fact the same as those that infiltrate the central nervous syst...
