Cellular and humoral immunity to acetylcholine receptor in myasthenia gravis.
At the same time in 21 myasthenic patients we measured a. the cellular immune response against acetylcholine receptor (AChR) of peripheral lymphocytes, T lymphocytes and non rosette forming lymphocytes (50% B lymphocytes); b. the antibodies to AChR and c. the antigenic modulation activity of their sera on rat myotube AChR. At least one of these parameters was positive in each patient and this further supports the relevance of the immune response to acetylcholine receptor in myasthenia gravis. Strict correlations between the response of lymphocytes, antigenic modulation, antibody titer and disease severity were not evident.
