Resumo: In this report we review current information on the phenotypic and functional properties of gammadelta T cells in demyelinating disorders. The results support the conclusion that although gammadelta T cells show evidence of activation in patients with either multiple sclerosis (MS) or Guillain Barrè syndrome (GBS), differences exist in the phenotypic and functional properties of these cells between the two diseases. In particular, our data indicate that in patients with MS the Vdelta2 subset is activated and that these cells can be induced to secrete high levels of proinflammatory cytokines. In contrast, in patients with GBS, the Vdelta1 subset is expanded and can be induced to secrete cytokines more associated with a humoral response.
