Introduction: The autoantibody-driven disease pemphigus vulgaris (PV) impairs desmosome adhesion in the epidermis. In desmosomes, the pemphigus autoantigens desmoglein 1 (Dsg1) and Dsg3 link adjacent cells. Dsgs are clustered by plaque proteins and linked to the keratin cytoskeleton by desmoplakin (Dp).

Autoimmune cerebellar ataxia (ACA) is a cerebellar syndrome induced by autoimmune reactions and its onset is induced by malignant tumors, prodromic infection, and gluten allergy. Its clinical symptoms include gait disorder, limb ataxia, dysarthria, and dysphagia. According to , the diagnosis of ACA is based on the following points: 1.

Introduction: Our aim was to investigate the insufficiently understood differences in the immune system between anti-citrullinated peptide antibody (ACPA)-positive (ACPA) and ACPA-negative (ACPA) early rheumatoid arthritis (eRA) patients.
Methods: We performed multiple cytokine assays using sera from drug-naïve ACPA and ACPA eRA patients. Additionally, we conducted single-cell RNA sequencing of CD45 cells from peripheral blood samples to analyze and compare the distribution and functional characteristics of the cell subsets based on the ACPA status.

Background: Autoimmune encephalitis (AE) is a rare and recently described neuroinflammatory disease associated with specific autoantibodies. Anti-leucine-rich glioma inactivated 1 (anti-LGI1) encephalitis is a rare but treatable type of AE discovered in recent years. Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia.

Background: Autoimmune bullous disorder (AIBD) is a diverse group of blistering dermatoses that affects the skin and mucous membrane, characterized by the formation of autoantibodies against the desmosomal glycoproteins and adhesion molecular components of the basement membrane zone. Various immunoassay techniques for serological diagnosis are Direct Immunofluorescence (DIF), Indirect Immunofluorescence (IIF), Enzyme Linked Immunosorbent Assay (ELISA) and immunoblotting. Quantitative ELISA titer can also be used to monitor the disease activity and response to treatment.
