Die Myasthenia gravis ist eine relativ seltene Erkrankung. Seronegative myasthenia gravis is a form of MG where autoantibodies (anti-AChR and anti-MuSK autoantibodies) are not detectable in the blood.

The sensitivity of the assay has a marked effect on the proportion of patients in whom antibodies are detected. Epub 2014 Dec 6. Jon Lindstrom, ‘Seronegative’ myasthenia gravis is no longer seronegative, High-affinity IgG autoantibodies to muscle nicotinic acetylcholine receptors (AChRs) were discovered to cause myasthenia gravis (MG) and its animal model more than 30 years ago (Patrick and Lindstrom, Angela Vincent and her co-workers discovered that about half of the putative seronegative MG patients actually had autoantibodies to muscle-specific kinase (MuSK) (Hoch In classical seropositive MG, autoantibodies bound to the AChRs impair neuromuscular transmission by three mechanisms (Lindstrom, fixation of complement that causes focal lysis of the post-synaptic membrane that reduces the number of AChRs and disrupts their localization next to sites of ACh release;cross-linking of AChRs by antibodies increases their rate of endocytosis, which causes loss of AChRs by the process of antigenic modulation; andrarely, autoantibodies directly impair AChR function either competitively or non-competitively.The discovery of autoantibodies to MuSK still left ∼12% of MG patients as seronegative, yet clinically and by thymic and endplate pathology appearing much like seropositive MG patients (Vincent and Leite, Problems with the assay are that it provides subjective qualitative results evaluated by microscopy rather than objective quantitative assay values in moles of toxin-labelled AChRs bound per litre of serum obtained by γ counting in the conventional assay for high-affinity autoantibodies; and the transient transfection and evaluation of binding are very laborious compared to an immunoprecipitation assay. 2015 Jun;72(6):642-9. doi: 10.1001/jamaneurol.2015.0203.J Huazhong Univ Sci Technolog Med Sci.

A less sensitive assay identifies fewer seropositive patients and the proportion of SN-MG is therefore greater. 2009 Jan;9(1):1-8. doi: 10.1517/14712590802588831.Evoli A, Tonali PA, Padua L, Monaco ML, Scuderi F, Batocchi AP, Marino M, Bartoccioni E.Brain.

High-affinity IgG autoantibodies to muscle nicotinic acetylcholine receptors (AChRs) were discovered to cause myasthenia gravis (MG) and its animal model more than 30 years ago (Patrick and Lindstrom, 1973; Lindstrom et al., 1976a, b; Vincent et al., 2006), and the antigenic structure of muscle AChRs is still being actively investigated (Kalamida et al., 2007; Lindstrom et al., 2008). 2015;2015:197893. doi: 10.1155/2015/197893.
