Myasthenia gravis associated with HTLV-I infection and atypical brain lesions.

abstract：INTRODUCTION:Myasthenia gravis (MG) is a B-cell-mediated autoimmune disease. B-cell-activating factor (BAFF) is a major factor in B-cell development and activation. In this study we investigated serum BAFF levels in MG patients. METHODS:We compared the serum BAFF levels of 20 MG patients with gender-matched healthy co...
