Acetylcholine receptor epitope in proteins of myasthenia gravis-associated thymomas and non-thymic tissues.


Immunohistochemical studies have shown that almost all thymomas of myasthenia gravis (MG) patients contain proteins which share antigenic determinants with the nicotinic acetylcholine receptor (AChR) of human muscle. Here we describe one of the proteins (p153) which (1) is not part of a compound structure, (2) has a MW of 153 kd, (3) has an isoelectric… (More)
