However, conventional analytical approaches have failed to elucidate their activation mechanisms from a global perspective. In this study, we isolated a highly branched glycogen (GCEP2a) from eggs of the sea urchin <em>Glyptocidaris crenularis</em>. Structural characterization revealed that GCEP2a possesses a backbone composed of →4)-α-D-Glc<em>p</em>-(1 → residues, with one C6-branch per five residues, and a molecular weight of 8.06 × 10<sup>3</sup> kDa. Employing nascent-proteome bioorthogonal non-canonical amino acid tagging (BONCAT) enrichment followed by DIA-FAIMS, we unraveled the global immunostimulatory mechanisms of GCEP2a in RAW264.7 macrophages. This advanced approach enabled dynamic profiling of nascent protein synthesis, uncovering a multi-receptor and multi-pathway regulatory network. Specifically, GCEP2a activates signaling consistent with engagement of the toll-like receptors (TLRs), C-type lectin receptors (CLRs), and RIG-I-like receptors (RLRs), thereby triggering downstream signaling cascades including the NF-κB, MAPK, and PI3K-AKT pathways. Additionally, GCEP2a downregulates the biosynthesis of lacto- and neolacto-series glycosphingolipids, indicating metabolic reprogramming associated with M1 polarization. These findings not only suggest that GCEP2a exhibits potential as an immune adjuvant, but also provide initial insights into the application of BONCAT-based nascent proteomics for investigating the multi-modal immunostimulatory mechanisms of marine polysaccharides.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"370 ","pages":"Article 124473"},"PeriodicalIF":12.5,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145217606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spinning solutions in NMMO can be made from cellulose with a high concentration of impurities (lignin, hemicellulose, etc.). Metals that affect solvent and polymer stability are an exception; their content should not exceed the acceptable levels. Conditioning fibers in baths of diverse compositions is one of the most important stages of structure formation. Keeping fibers made from paper-grade pulp in conditioning baths causes changes in not only the size of crystallites and the degree of crystallinity, but also in mechanical characteristics. Thus, after completely removing the solvent and immersing the fibers in alcohol, the crystallinity rises as compared to fibers that have just received water baths.

Edible and medicinal mushroom polysaccharides (EMMPs), as naturally derived “biological response modifiers”, are essential for maintaining host health owing to their unique chemical structures and diverse biological functions. However, current structural analysis techniques still face challenges in characterizing the highly heterogeneous polysaccharides. Meanwhile, the multi-target and multi-pathway interaction effects between polysaccharides and organisms remain incompletely elucidated, which severely restricts the development and application of EMMPs. In light of these challenges, this paper reviews the latest advances concerning the structural features and bioactivities of EMMPs. The structure-function relationships of EMMPs are elucidated through synthesizing structural analysis strategies and integrating target molecules and signaling pathways related to health benefits.
