  • Title: Anti-AChR antibodies, thymic histology, and T cell subsets in myasthenia gravis.

    Journal: Neurology; 1984 Jan; 34(1):66-71. PubMed ID: 6228745.
    Abstract:
    The relationship between the titers of antibody against acetylcholine receptor (AChR) and T helper/suppressor balance (assessed by the OKT4/OKT8 ratio) were investigated in 74 patients with myasthenia gravis (MG). All patients with elevated AChR antibody titers (greater than 100 nM) had hyperplastic thymuses, while most patients with low or negative antibody titers (less than 1 nM) had involuted thymuses. All patients with thymoma had positive, though not very high, antibody titers. No correlation was found between anti-AChR antibody levels and OKT4/OKT8 ratios except for patients with thymoma. Thus, it appears that AChR antibody titers are more closely related to thymic pathology than to peripheral T cell imbalance. These results are consistent with the hypothesis giving a central role to thymic lymphocytes in the AChR antibody production, either as antibody producer B cells or helper T cells.
