title: Differences in acetylcholine receptor-antibody interactions between extraocular and extremity muscle fibers.
abstract: There are two types of motor nerve innervation patterns and AChR distributions in human EOM: single and multiple. The latter is further divided into two subgroups that are restricted to EOM and are not found in limb muscles. Epitopes that are unique to EOM end-plates exist. Some OMG patients have antibodies that are specifically targeted to those epitopes. These antibodies are functionally active and can cause AChR loss in EOM end-plates. In addition to AChRs, specific components constructing the microenvironment surrounding them may also be involved in the susceptibility of EOM in myasthenia gravis.
