Antigenic difference of acetylcholine receptor between single and multiple form endplates of human extraocular muscle.
The acetylcholine receptor (AChR) of human extraocular muscle (EOM) has been studied by the immunological method using anti-AChR antibodies obtained from the sera of patients with myasthenia gravis (MG) of ocular type, whose symptoms have been restricted to EOM. Those antibodies could distinguish the AChR of multiple (en grappe) form endplates from that of single (en plaque) form endplates. This result indicates the antigenic difference of AChR between those two forms of endplates of human EOM.
