Abstract: In myasthenia gravis (MG), the neuromuscular transmission is impaired mainly by auto-antibodies against the acetylcholine receptor (AChR) or MuSK. In about 5% of the MG patients, however, the auto-antigen is still unknown. We investigated whether these idiopathic MG patients (iMG) have auto-antibodies against ErbB proteins, which influence the AChR density at the NMJ. Our results show reduced mRNA expression levels of ErbB4 in thymus tissue of iMG patients compared to AChR-MG and non-MG patients, but we could not detect anti-ErbB antibodies in sera of iMG patients. Therefore, our results do not support a role for ErbB receptors as auto-antigens in iMG patients. (C) 2010 Elsevier B.V. All rights reserved.
