expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...

chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (pufas) are required for both animal and human health. the n-3 pufas, especially, eicosapentaenoic acid (epa) and docosahexaenoic ...

background: this study aimed to compare the cytochrome p450 1a1 (cyp1a1) gene expression in the cord blood of infants born from mothers living in low- and high-air polluted areas. materials and methods: te study was conducted in spring 2012 in isfahan, the second large and air-polluted city in iran. the study comprised 60 neonates, consisting of 30 infants born from mothers residing in areas wi...

Abstract B cell Maturation Antigen (BCMA) is a receptor that engages the cytokines BAFF and APRIL. BCMA known to play critical role in regulating proliferation, survival, differentiation into plasma cells. However, effect of on non-B cells has been understudied. We have previously shown regulates EAE, where −/−mice exacerbated disease compared +/+mice. The increased was associated with infiltra...

The exact role of adult thymus in autoimmune disease state is poorly understood. We show here that thymus regulated experimental autoimmune encephalomyelitis (EAE), an animal model for multiple sclerosis, as evidenced by loss of spontaneous recovery in thymectomized EAE mice. There was progressive enrichment for CD4 single-positive Foxp3(+) regulatory T cells in thymocytes during the course of ...

CD44 is expressed by a variety of cells, including glial and T cells. Furthermore, in the demyelinating lesions of multiple sclerosis, CD44 expression is chronically elevated. In this study, we demonstrate that targeted deletion of CD44 attenuated myelin oligodendrocyte glycoprotein peptide-induced experimental autoimmune encephalitomyelitis (EAE) through novel regulatory mechanisms affecting T...

OBJECTIVE To assess the immunomodulatory activity of methylthioadenosine (MTA) in rodent experimental autoimmune encephalomyelitis (EAE) and in patients with multiple sclerosis. METHODS We studied the effect of intraperitoneal MTA in the acute and chronic EAE model by quantifying clinical and histological scores and by performing immunohistochemistry stains of the brain. We studied the immuno...

Chemokines are essential for homeostasis and activation of the immune system. The chemokine ligand/receptor pairing CCL20/CCR6 is interesting because these molecules display characteristics of both homeostatic and activation functions. These dual characteristics suggest a role for CCR6 in the priming and effector phases of the immune response. However, while CCR6 has been implicated in the effe...

background and objectives: phosphlipases are a group of enzymes that breakdown phosphatidylcholine (phospholipids) molecules producing second products. these produced products have a divers role in the cell like signal transduction and digestion in humans. in this research the effect of phosphatidylcholine on the expression of plc genes of a. fumigatus was studied. the plc genes of this fungus ...

Abstract Monocyte recruitment into the central nervous system (CNS) is critical for driving pathology in neuroinflammatory diseases such as MS. The monocytic influx well activation of resident myeloid cells contribute to and subsequent re-activation autoreactive T cells, ultimately leading demyelinating lesions, axonal damage, progressive paralysis. Using murine model MS, experimental autoimmun...
