Abstract
Glycosylation is one of the most important post-translational modification in protein biosynthesis. Immunoglobulin glycosylation can exert anti-inflammatory or pro-inflammatory activity by regulating antibody stability and affecting its interaction with different FcγRs. In recent years, a large number of studies have confirmed that abnormal glycosylation of immunoglobulin plays a key role in the pathogenesis of autoimmune diseases. Its products, such as sugar chain structure or/and glycosylated proteins, can be detected by lectin microarray and other technologies, are expected to become new serum markers of autoimmune diseases. It has a broad application prospect in disease diagnosis, condition monitoring, prognosis evaluation and treatment.
Key words:
Immunoglobulins; Glycosylation; Autoimmune diseases; Immunoglobulin G
