زمینه و هدف: افزایش مشارکت سلول های بنیادی عصبی در ترمیم اندوژن آسیب های میلینی یکی از مهم ترین استراتژی ها برای درمان های نوین بیماری ام اس است. افزایش cAMP با فعال کردن PKA و همچنین مستقل از آن، ظرفیت ترمیمی مغز را افزایش می دهد. در مطالعه حاضر، اثر تزریق داخل صفاقی آنالوگ فعال آن (dbcAMP) بر مهاجرت سلول های بنیادی عصبی در مدل EAE بیماری ام اس بررسی شد. مواد و روش ها: در این مطالعه تجربی برای...
In this study, we have evaluated our recently developed method for antigen-cell coupling using sulfosuccinimidyl-4-[N-maleimidomethyl]cyclohexane-1-carboxylate (sulfo-SMCC) heterobifunctional crosslinker in prevention and reversal of experimental autoimmune encephalomyelitis (EAE). We demonstrate that infusion of MOG35-55-coupled spleen cells (MOG-SP) significantly prevents and reverses EAE. Fu...
BACKGROUND Regulatory T (Treg) cells can be induced with DNA vaccinations and protect mice from the development of experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis (MS). Tacrolimus (FK506) has been shown to have functions on inducing immunosuppression and augmenting apoptosis of pathologic T cells in autoimmune disease. Here we examined the therapeutic effect...
Experimental autoimmune encephalomyelitis (EAE) was induced in Lewis rats either by active immunization with myelin basic protein (MBP) or by adoptive transfer using anti-MBP specific CD4(+)T cells. Treatment with human polyclonal immunoglobulins (IgG) effectively suppressed active EAE. Time-dependent experiments demonstrated that the effect of IgG was manifested only when treatment was given i...
EAE, an animal model for MS, is a Th17 and Th1-cell-mediated autoimmune disease, but the mechanisms leading to priming of encephalitogenic T cells in autoimmune neuroinflammation are poorly understood. To investigate the role of plasmacytoid DC (pDC) in the initiation of autoimmune Th17- and Th1-cell responses and EAE, we depleted pDC with anti-pDC Ag-1 (anti-PDCA1) mAb prior to immunization of...
Dendritic cells (DCs) are pivotal for the development of experimental autoimmune encephalomyelitis (EAE). However, the mechanisms by which they control disease remain to be determined. This study demonstrates that expression of CC chemokine receptor 4 (CCR4) by DCs is required for EAE induction. CCR4(-/-) mice presented enhanced resistance to EAE associated with a reduction in IL-23 and GM-CSF ...
Experimental Autoimmune Encephalomyelitis (EAE) can be induced in mice of the C57BL/6 strain by subcutaneous immunization with myelin/oligodendrocyte glycoprotein (MOG) peptide p35-55 in CFA, administered twice at an interval of one week and supplemented with Bordetella pertussis toxin given IV. Here, we studied the effect on the induction of EAE of depleting antibodies to CD4, CD8, or CD25 adm...
Estrogens can signal through either estrogen receptor α (ERα) or β (ERβ) to ameliorate experimental autoimmune encephalomyelitis (EAE), the most widely used mouse model of multiple sclerosis (MS). Cellular targets of estrogen-mediated neuroprotection are still being elucidated. Previously, we demonstrated that ERα on astrocytes, but not neurons, was critical for ERα ligand-mediated neuroprotect...
Abstract Multiple Sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. Latent infection with Epstein-Barr virus (EBV) has been identified as necessary yet insufficient factor in development disease. Several groups have demonstrated that murine EBV analogue, MHV-68, exacerbates severity experimental encephalomyelitis (EAE). However, induction EAE requires immunizat...
Fingolimod (FTY720) is an oral therapy for relapsing remitting multiple sclerosis (MS) and targets sphingosine 1-phosphate receptors (S1PRs). FTY720 also rescues animals from experimental autoimmune encephalomyelitis (EAE), an animal model of MS. The protective effects of FTY720 in EAE are primarily scored manually by examining weight loss and limb paralysis that begins around 10-12 days after ...
