In this study, we investigated the therapeutic potential of GM1 ganglioside and its oligosaccharide portion (OligoGM1) in a cellular model of GBA-associated Parkinson's disease, using SH-SY5Y neuroblastoma cells carrying the L444P GBA mutation. We observed that both GM1 and OligoGM1 reduced α-synuclein accumulation and improved cell viability. Notably, only OligoGM1 attenuated lysosomal overload and restored mitophagy. Additionally, OligoGM1 significantly prevented 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced toxicity, including lysosomal dysfunction, reactive oxidative species-overproduction, and mitochondrial energy failure, whereas GM1 failed to provide protection. These findings highlight the selective and multifaceted neuroprotective actions of OligoGM1 under both genetic conditions and environmental stress. Due to its small, hydrophilic nature and capacity to cross the blood-brain barrier, OligoGM1 emerges as a promising therapeutic candidate for GBA-related and potentially idiopathic forms of Parkinson's Disease.","PeriodicalId":12762,"journal":{"name":"Glycoconjugate Journal","volume":" ","pages":"159-171"},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144215652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the enormous economic and social impact, vaccines and reliable diagnostic measures are still lacking for these diseases. The main obstacle to developing accurate diagnostic methods and an active vaccine is the parasite’s ability for antigenic variation, impairment of B cell maturation, and loss of B cell memory which collectively prevent the development of a long-lasting, effective immune response. The antigenic variation is sustained by random gene switching, segmental gene conversion, and altered glycosylation states of solvent-exposed regions of the corresponding variant surface glycoproteins (VSGs). These glycoproteins use a glycosylphosphatidylinositol (GPI) anchor for attachment to the membrane. GPIs of T. brucei have specific branched structures that are further heterogeneously galactosylated. Here, we synthesized a glycan fragment library containing T. brucei GPIs’ most prominent structural features and performed an epitope mapping using mice and human sera of infected specimens using glycan microarrays. The studies indicate that in contrast to VSGs, T. brucei GPIs are recognized by infection-induced short-lived Immunoglobulin M (IgM) and long-lasting Immunoglobulin G (IgG), suggesting a specific immune response against GPI structures.

The most common mutation, F508del, causes CFTR misfolding, premature degradation, and impaired mucociliary clearance, leading to recurrent respiratory infections and inflammation. The triple combination therapy with Elexacaftor, Tezacaftor, and Ivacaftor (ETI) has revolutionized CF management by partially restoring mutated CFTR function. However, enhancing CFTR rescue and stabilizing host immune responses remain critical challenges. In airway epithelial cells, CFTR interacts with proteins and lipids in macromolecular complexes that influence its stability. Among these, the ganglioside GM1 plays a key role in modulating plasma membrane protein dynamics, including CFTR. This study investigates the effects of exogenous GM1 supplementation as an adjuvant to ETI treatment. Our results demonstrate that GM1 enhances F508del-CFTR maturation and stability, even under Pseudomonas aeruginosa infection, which typically suppresses CFTR expression and function. Furthermore, GM1 restores xenophagic activity in bronchial epithelial cells, improving host defence mechanisms against the bacteria. These findings underscore the therapeutic potential of GM1 and its analogues in optimizing the plasma membrane environment for CFTR correction, suggesting that by enhancing the efficacy of CFTR modulators, GM1 could pave the way for innovative approaches to improve CF management.","PeriodicalId":12762,"journal":{"name":"Glycoconjugate Journal","volume":" ","pages":"173-186"},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144636797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we discuss the pathophysiological mechanisms of salivary gland dysfunctions in diabetes, focusing on the role of AGEs.

Structural and ultrastructural alterations have been described in the three major salivary glands, and hypo-salivation development has been linked to early autonomic neuropathy. Poor metabolic control aggravates the salivary flow rate via injury to the autonomic nerve fiber bundles or direct damage to the secretory acinar cells of the glands. Chronic hyperglycemia, the most crucial feature of diabetes, leads to the generation and accumulation of advanced glycation end products (AGEs). The interest in the role of AGEs in the pathogenesis of diabetic complications has grown exponentially, and AGEs have been implicated as a primary culprit in the pathophysiology of diabetes and its various complications, including neuropathy, nephropathy, retinopathy, vasculopathy, and cardiomyopathy.","PeriodicalId":12762,"journal":{"name":"Glycoconjugate Journal","volume":" ","pages":"97-106"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143709557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implicit Ca2+ ions are crucial to CRD function. Increment of the ionic concentration explicitly affects the CPS recognition by CRD many-fold. DC-SIGN is one such CLR that acts for the differential recognition of the microbial CPS. The CPS mannotriose had the lowest binding energy (ΔG -4.7 kcal/mol) and the maximum affinity for DC-SIGN with implicit Ca2+ ion. In the present investigation the ligand affinity increases with the rise of Ca2+ concentration up to 1.5 M. Again, within the CRD the residues viz; Glutamate (347), Proline (348), and Asparagine (349) (EPN) were reported previously as essential for CPS unit coordination. Our analysis demonstrated that besides the EPN residues, CPS unit interacts with the neighboring Asparagine (350), Glutamate (354) and Asparagine (355) residues. Thus, these residues were replaced one at a time with Alanine (a charge neutral residue) to test their effect on the contact event. The CRD loses its affinity for recognition on the N350A, E354A, and D355A substitutions. Thus, this heterogeneity of CRD recognition towards Carbohydrate provides fresh information about the immune system's theragnostic function. This new understanding of Ca2+-induced recognition may help design new theragnostic applications that boost our immune defenses against pathogenic evasion.","PeriodicalId":12762,"journal":{"name":"Glycoconjugate Journal","volume":" ","pages":"61-76"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143448914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence and function of relevant enzymes has been suggested by gene knockout or mutation and corresponding aberrant phosphorylcholine metabolism. In the current study, the Mycoplasma fermentans phosphorylcholine transferase mf1, with previously confirmed in-vitro activity synthesizing phosphorylcholine-α-glucosyl-1,2-dipalmitoyl glycerol, is demonstrated to not only transfer phosphorylcholine but also phosphoethanolamine from CDP-ethanolamine. Moreover, mf1 is capable of using the β-configuration of the presumed natural substrate but transfers neither to simpler substrates with glucose moieties such as β-D-octyl-glucopyranoside nor to an extended lipid substrate with an additional galactose residue. These findings suggest a certain, but limited, substrate flexibility for bacterial PC-transferases. Mf1 activity is inhibited by β-glycerophosphate, an isomer of part of CDP-glycerol which is known to compete with CDP-ribitol in enzymatic reactions catalyzed by fukutin, a human protein sharing structural homology with mf1.

Especially, the therapeutic glycosides can be classified into many compounds based on the sugar moiety, chains/ saccharide units, glycosidic linkages, and aglycones. Among many classes, the widely used pharmacological classification is based on the aglycones linked to the glycoside molecule. Based on these non-sugar moiety (aglycones), plant glycosides are further classified into twelve different types of glycosides along with the recent discovery of novel (cannabinoid) glycosides. They are called alcoholic, anthraquinone, coumarin, chromone, cyanogenic, flavonoid, phenolic, cardiac, saponin, thio, steviol, iridoid, and cannabinoid glycosides. Each of the plant glycosides has been discussed in this paper with, origin, structure, and abundant presence in a specific family of plants. Besides, the therapeutic roles of these plant glycosides are further described in detail to validate their efficacies in the human health care system. On the other hand, glycosides are inactive until enzymatic hydrolysis releases their active aglycone, enabling targeted drug delivery. This process enhances aglycone solubility and stability, improving bioavailability and therapeutic efficacy. They target specific receptors or enzymes, minimizing off-target effects and enhancing pharmacological outcomes. Derived from plants, glycosides offer diverse chemical structures for drug development. They are integral to traditional medicine and modern pharmaceuticals, utilized in therapies ranging from cardiology to antimicrobial treatments.","PeriodicalId":12762,"journal":{"name":"Glycoconjugate Journal","volume":" ","pages":"107-124"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143482972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the CSs from cartilaginous fish showed concentration-dependent cell proliferative activity of 3T3-L1 cells within the retrieved concentration range (0-1,000 μg/mL), while under induction of adipocyte differentiation, they inhibited lipid accumulation. In particular, Ms-CS and Sp-CS were highly active in inhibiting lipid accumulation in the cells. The present study revealed that cartilaginous fish-derived CS has inhibitory activity on 3T3-L1 adipocyte differentiation by suppressing lipid droplet accumulation, although the degree of suppression varied depending on the composition of the CS and its origin. In addition, a significant increase in chondroitin sulfate N-acetylgalactosaminyltransferase 2 (Csgalnact2) expression of the Sp-CS group at the concentration of 500 µg/mL was observed. Csgalnact2 expression is associated with chondroitin N-acetylgalactosaminyltransferase-2 (ChGn-2), one of the glycosyltransferases that catalyzes the chain initiation and elongation of the CS backbone in its biosynthesis. Exogenous CS from cartilaginous fishes increased Csgalnact2 expression, although further studies are needed to confirm changes in CS biosynthesis. We observed reduced lipid accumulation in differentiated 3T3-L1 cells. Our findings highlight the role of CS polysaccharides, in inhibiting adipogenesis, even though further investigation is required to understand the underlying mechanism.","PeriodicalId":12762,"journal":{"name":"Glycoconjugate Journal","volume":" ","pages":"77-86"},"PeriodicalIF":3.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143596748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
