Background: Neuromyelitis optica spectrum disorder (NMOSD) is a clinically defined, inflammatory central nervous system (CNS) disease of unknown cause, associated with humoral autoimmune findings such as anti-aquaporin 4 (AQP4)-IgG. Recent clinical trials showed benefit anti-B cell and anti-complement-antibodies in NMOSD, suggesting relevance anti-AQP4-IgG pathogenesis. Objective: AQP4-IgG NMOS...

non-enzymatic glycosylation of proteins is one of the key mechanisms in the pathogenesis of diabetic complications. glycation of igg is of special interest due to its possible influence on the functionality of immunoglobulins and overall immuno-competence. the aim of this study was to clarify more details of in vitro glycation of igg and to study the effect of this modification on its interatio...

Background/aim: In this study, we aimed to investigate different types of celiac antibodies in psoriasis patients and see if the presence was associated with other variables. Materials methods: We included plaque who were followed up our dermatology clinic between February 2019 2021 added a healthy control group for comparison. The studied serum antitissue transglutaminase (tTG)-IgA, tTG-IgG, a...

Background: BK virus, a human polyomavirus, causes nephropathy and allograft loss in renal transplant recipients. Although it was discovered 1971, understanding of the humoral immune response to BKV is limited.
 Objective: To serological detection level estimation anti-BK-IgG renal-transplanted recipients healthy blood donors as control.
 Patients Methods: Serum samples were collected...

The presence of IgG antibodies (Abs) to Aspergillus fumigatus (Af) is a crucial diagnostic criterion for allergic bronchopulmonary aspergillosis (ABPA). Although precipitation traditionally used document Abs, anti-Af serum levels can also be measured by enzyme immunoassay (EIA). However, there are insufficient data on the optimal cut-offs assess performance EIA method. This study aimed determin...
