In vivo enzymatic modulation of IgG glycosylation inhibits autoimmune disease in an IgG subclass-dependent manner.
IgG antibodies are potent inducers of proinflammatory responses. During autoimmune diseases such as arthritis and systemic lupus erythematosus, IgG autoantibodies are responsible for the chronic inflammation and destruction of healthy tissues by cross-linking Fc receptors on innate immune effector cells. The sugar moiety attached to the asparagine-297 residue in the constant domain of the antib...
متن کاملChanges in glycosylation of IgG during fasting in patients with rheumatoid arthritis.
Patients with rheumatoid arthritis (RA) have a higher proportion of agalactosyl IgG than healthy individuals. Glycosylation status was examined in 26 RA patients who fasted for 7-10 days and afterwards followed a vegetarian diet for 3.5 months. The decrease in the proportion of agalactosyl IgG correlated significantly with the clinical improvement after the fasting period, but not after the veg...
متن کاملThe N-Glycosylation of Mouse Immunoglobulin G (IgG)-Fragment Crystallizable Differs Between IgG Subclasses and Strains
N-linked glycosylation of the fragment crystallizable (Fc)-region of immunoglobulin G (IgG) is known to have a large influence on the activity of the antibody, an effect reported to be IgG subclass specific. This situation applies both to humans and mice. The mouse is often used as experimental animal model to study the effects of Fc-glycosylation on IgG effector functions, and results are not ...
متن کاملGlycosylation of plasma IgG in colorectal cancer prognosis
In this study we demonstrate the potential value of Immunoglobulin G (IgG) glycosylation as a novel prognostic biomarker of colorectal cancer (CRC). We analysed plasma IgG glycans in 1229 CRC patients and correlated with survival outcomes. We assessed the predictive value of clinical algorithms and compared this to algorithms that also included glycan predictors. Decreased galactosylation, decr...
متن کاملEstrogens regulate glycosylation of IgG in women and men.
The immunologic potency of IgG is modulated by glycosylation, but mechanisms regulating this process are undefined. A role for sex hormones is suggested by differences in IgG glycans between women and men, most prominently with respect to galactose. We therefore assessed IgG galactosylation in 713 healthy adults from 2 cohorts as well as in 159 subjects from 4 randomized controlled studies of e...
