Investigation of N-Glycan Functions in Receptor for Advanced Glycation End Products V Domain through Chemical Glycoprotein Synthesis.

The receptor for advanced glycation end products (RAGE) plays a crucial role in inflammation-related pathways and various chronic diseases. Despite the recognized significance of N-glycosylation in the ligand-binding V domain (VD) of RAGE, a comprehensive understanding of the site-activity and structure-activity relationships is lacking due to the challenges in obtaining homogeneous glycoprotein samples through biological expression. Here, we combined chemical and chemoenzymatic approaches to synthesize RAGE-VD and its congeners with Asn3-glycosylation by incorporating precise N-glycan structures.

Ginsenoside compound K plays an anti-inflammatory effect without inducing glucose metabolism disorder in adjuvant-induced arthritis rats.

Ginsenoside compound K (GCK) possesses a glucocorticoid (GC)-like structure and functions as an agonist of the glucocorticoid receptor (GR), thereby exerting anti-inflammatory effects through GR activation. However, it remains unclear whether GCK leads to hyperglycemia, which is a known adverse reaction associated with classical GCs. In this study, we have successfully demonstrated that GCK exerts its anti-inflammatory effects in a rat model of adjuvant arthritis without impacting gluconeogenesis and pentose phosphate pathways, thus avoiding any glucose metabolism disorders.

Role of lactate and lactate metabolism in liver diseases (Review).

Lactate is a byproduct of glycolysis, and before the Warburg effect was revealed (in which glucose can be fermented in the presence of oxygen to produce lactate) it was considered a metabolic waste product. At present, lactate is not only recognized as a metabolic substrate that provides energy, but also as a signaling molecule that regulates cellular functions under pathophysiological conditions. Lactylation, a post‑translational modification, is involved in the development of various diseases, including inflammation and tumors.

Exploiting the advantages of cationic copolymers and AgBr nanoparticles to optimize the antibacterial activity of chitosan.

Composite adaptive fuzzy bipartite consensus of fractional-order multiagent systems with a switched event-triggered mechanism.

This paper focuses on online recorded-data-based composite adaptive fuzzy bipartite consensus control for uncertain fractional-order multiagent systems with interconnected terms and external disturbances by employing a switched-threshold-based event-triggered mechanism (ETM) under the backstepping structure. Fuzzy logic system is used as a universal function approximation to deal with function uncertainties that are not prone to model in the system. A new composite learning adaptive parameter design scheme that synthesizes both prediction error and tracking error is developed to enhance the tracking performance, where the prediction error is raised from the utilization of online recorded data and instantaneous data.

Tau truncation in the pathogenesis of Alzheimer's disease: a narrative review.

Alzheimer's disease is characterized by two major neuropathological hallmarks-the extracellular β-amyloid plaques and intracellular neurofibrillary tangles consisting of aggregated and hyperphosphorylated Tau protein. Recent studies suggest that dysregulation of the microtubule-associated protein Tau, especially specific proteolysis, could be a driving force for Alzheimer's disease neurodegeneration. Tau physiologically promotes the assembly and stabilization of microtubules, whereas specific truncated fragments are sufficient to induce abnormal hyperphosphorylation and aggregate into toxic oligomers, resulting in them gaining prion-like characteristics.

Ginsenoside compound K exerts anti-inflammatory effects through transcriptional activation and transcriptional inhibition of glucocorticoid receptor in rheumatoid arthritis fibroblast-like synoviocytes.

Ginsenoside compound K (GCK) has anti-inflammatory and immunoregulatory effects, and glucocorticoid receptor (GR) has been considered as its potential target. But the mechanism by which GCK exerts its anti-inflammatory effects after GR activation remains unclear. In this study, molecular docking, isothermal titration calorimetry, siRNA of GR and GRA458T mutation were used to confirm the anti-inflammatory mechanism of GCK targeting GR in fibroblast-like synoviocytes (FLS).
