Abstract The Experimental autoimmune neuritis (EAN) is considered the experimental model of Guillain-Barré's syndrome. The EAN is an autoimmune disease characterized by the infiltration of mononuclear cells into the endoneural space. There is an activation of auto-reactive cells against peripheral myelin compounds. This response in characterized mainly by lymphocytes Th1 and/or Th17, which culminate with the myelin destruction. During the scientific initiation program we were able to demonstrate that the treatment with one hematopoietic factor, G-CSF, ameliorates the clinical signs of EAN. The group treated with G-CSF decreased the expression of proinflammatory cytokines (IFNg, IL-17a) and increased the expression of anti-inflammatory cytokines (IL-10, TGFb) and the percentage of regulatory T cells. However, our data do not explain completely the phenomena. The use of lower dosis did not present the changes of inflammatory profile observed for the optimal dose. Despite of that, the lower dosis ameliorates the clinical signs and decrease the number of cells infiltrated into the nerve. Therefore, is our objective to study the migratory pattern, using adoptive transfer of GFP transduced neuritogenic cells, during the evolution of EAN in the treated and untreated animals. | |
