Abstract
Autoimmune autonomic ganglionopathy (AAG) is a rare acquired immune-mediated neurological disease that causes various autonomic symptoms. AAG is induced by autoantibodies for the α3 and β4 subunits of the ganglionic acetylcholine receptor (gAChR). gAChR antibodies mediate synaptic transmission in all autonomic ganglia, resulting in dysautonomia. Recent clinical and basic research topics in AAG include the following: 1)analysis of clinical features; 2)novel methods for gAChR antibody detection; 3)efficacy of combined immunotherapy; 4)novel experimental AAG; 5)COVID-19 and mRNA COVID-19 vaccination and its association with autonomic dysfunction; and 6)dysautonomia as an immune-related adverse event of immune checkpoint inhibitors in cancer therapy. The author and his collaborators have previously established "10 assignments" to understand the basic research and clinical issues of AAG. In this review, the author describes the current status of research on each of the "10 assignments," incorporating research trends over the last five years.
