Obesity, a major global health problem, is associated with increased cardiometabolic morbidity and mortality. Protein glycosylation frequent posttranslational modification, highly responsive to inflammation ageing. The prospect of biological age reduction, by changing patterns through metabolic intervention, opens many possibilities. We have investigated whether weight loss interventions affect inflammation- ageing-associated IgG changes, in longitudinal cohort bariatric surgery patients. To...

Gonadal hormones affect immunoglobulin G (IgG) glycosylation, and the more proinflammatory IgG glycome composition might be one of molecular mechanisms behind increased phenotype in perimenopause. Using ultra-high-performance liquid chromatography, we analyzed 5,080 samples from 1940 pre-, peri-, postmenopausal women. Statistically significant decrease galactosylation sialylation was observed Furthermore, during transition pre- to period, rate increase agalactosylated structures (0.051/yr;...

Nuclear magnetic resonance (NMR) spectra of blood serum and plasma show signals arising from metabolites, lipoproteins, N-acetyl methyl groups N-glycans covalently linked to acute-phase proteins. These glycan often called glycoprotein A (GlycA) B (GlycB) arise have been proposed as biomarkers, initially for cardiovascular diseases, but also other inflammatory conditions. For the detection resonances, J-edited, diffusion, relaxation filtered NMR spectroscopy (JEDI) has suppress lipoprotein...

Crohn’s disease (CD) is a chronic inflammation of the digestive tract that significantly impairs patients’ quality life and well-being. Anti-TNF biologicals revolutionised treatment CD, yet many patients do not adequately respond to such therapy. Previous studies have demonstrated pro-inflammatory pattern in composition CD immunoglobulin G (IgG) N-glycome compared healthy individuals. Here, we utilised high-throughput UHPLC method for N-glycan analysis explore longitudinal effect anti-TNF...

Objectives: Glycosylation of immunoglobulin G (IgG) is an important regulator the immune system and has been implicated in prevalent hypertension. The aim this study to investigate whether IgG glycome begins change prior hypertension diagnosis by analysing composition a large population-based female cohort with two independent replication samples. Methods: We included 989 unrelated cases incident 1628 controls from TwinsUK (mean follow-up time 6.3 years) measured at baseline...

Obesity-induced inflammation activates the adaptive immune system by altering immunoglobulin G (IgG) glycosylation in a way to produce more proinflammatory antibodies. The IgG glycome has already been well studied, and its alterations are correlated with high body mass index (BMI) central adiposity. Still, N-glycome susceptibility different dietary regimes for weight control after initial loss not studied. To explore changes induced subsequent weight-maintenance diets, we analyzed 1,850...

Abstract Background Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of melanoma and other cancers. However, no reliable biomarker survival or response has entered clinic to identify those patients with who are most likely benefit from ICIs. Glycosylation affects proteins lipids’ structure functions. Tumours characterized by aberrant glycosylation which may contribute their progression hinder an effective antitumour immune response. Methods We aim at identifying novel...

Regular exercise improves health, modulating the immune system and impacting inflammatory status. Immunoglobulin G (IgG) N-glycosylation reflects changes in status; thus, we investigated impact of regular on overall status by monitoring IgG a previously inactive, middle-aged, overweight obese population (50.30 ± 9.23 years, BMI 30.57 4.81). Study participants (N = 397) underwent one three different programs lasting months with blood samples collected at baseline end intervention. After...

Abstract Protein glycosylation is the attachment of a carbohydrate moiety to protein backbone affecting both structure and function protein. Abnormal associated with various diseases, some changes in are detectable even before symptom development. As such, glycans have emerged as compelling new biomarker candidates. A wide range analytical methods exist for small-scale glycan analyses. However, there growing need highly robust reproducible high-throughput techniques that allow large-scale...
