Several studies have tried to determine the relationship between autoantibodies against the acetylcholine receptor and the development of pemphigus vulgaris. In this study, we observed that antibody levels against the acetylcholine receptor are mildly elevated in pemphigus vulgaris (PV), and significantly correlate with disease severity on the initial diagnosis and during follow up. However, it is not clear if these antibodies are just an epiphenomenon or a potential trigger of the known pathogenic process in PV.

The specific pathogeneses of schizophrenia (SCZ) remain an enigma despite extensive research that has implicated both genetic and environmental factors. Recent revelations that dysregulated immune system caused by glial cell overactivation result in neuroinflammation, a key player in neurodegenerative as well as neuropsychiatric disorders including SCZ are providing novel clues on potential therapeutic interventions. Here, we review the roles of glial cells (Dr.

Cinnamomum, a genus within the Lauraceae family, has gained global recognition due to its wide-ranging utility. Extensive research has been dedicated to exploring its phytochemical composition and pharmacological effects. Notably, the uniqueness of Cinnamomum lies in its terpenoid content, characterized by distinctive structures and significant biological implications.

Autoimmune autonomic ganglionopathy (AAG) is a rare and acquired immune-mediated disease that leads to wide autonomic failure, mainly characterized by orthostatic hypotension, gastrointestinal dysfunction, anhidrosis and poorly reactive pupils. This disorder is usually associated with autoantibodies to the ganglionic nicotinic acetylcholine receptor (gAChR-Ab). In this study, we describe a case of a gAChR-Ab-positive AAG patient with two therapeutic stages.

Background And Objectives: There is paucity of studies on long-term remission of autoimmune generalized myasthenia gravis (MG) from Southeast Asia. We report the outcome predictors of generalized MG and also evaluate the influence of high- versus low-dose prednisolone and prednisolone with or without azathioprine (AZA).
Methods: Fifty-seven patients with generalized MG were included, who completed 2 years of follow-up.
