[PMID: 39280626 PMCID: PMC11401205 DOI: 10.1016/j.isci.2024.110766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 07/13/2024] [Accepted: 08/15/2024] [Indexed: 09/18/2024] Open
Abstract
Recently, increasing evidence has shown the association between liver abnormal inflammation and cognition impairment, yet their age-related pathogenesis remains obscure. Here, our study provides a potential mechanistic link between liver macrophage excessive activation and neuroinflammation in aging progression. In aged and LPS-injected C57BL/6J mice, systemic administration of β-chitosan ameliorates hepatic macrophage-driven inflammation and reduces peripheral accumulations of TNF-α and IL-1β. Downregulation of circulatory pro-inflammatory cytokines then decreases vascular VCAM1 expression and neuroinflammation in the hippocampus, leading to cognitive improvement in aged/LPS-stimulated mice. Interestingly, β-chitosan treatment also exhibits the beneficial effects on the behavioral recovery of aged/LPS-stimulated zebrafish and Caenorhabditis elegans. In our cell culture and molecular docking experiments, we found that β-chitosan prefers shielding the MD-2 pocket, thus blocking the activation of TLR4-MD-2 complex to suppress NF-κB signaling pathway activation. Together, our findings highlight the extensive therapeutic potential of β-chitosan in reversing aged-related/LPS-induced cognitive impairment via the liver-brain axis.

Abstract
Chitosan is a polymeric polysaccharide with widely application. At present, commercialized chitosan obtained by deacetylating chitin with acid-alkali method. The homogeneity of the molecular weight of chitosan is difficult to adjust due to the low homogeneity of chitosan itself and the degradation effect of the extraction process. And the single source of raw material has limited the further development of chitosan. In this study, diatoms were used as the source of chitosan extraction through alkalization freeze-thaw method, and response surface methodology was also used to optimize the best preparation conditions of diatom chitosan. The extracted chitosan from diatom was β-type chitosan with low molecular weight, great homogeneity. Diatom chitosan was able to reduce blood loss and clotting time >30 % in vivo experiment compared to control. The hemolysis rate of diatom chitosan was lower than 1 %, and the survival rate was higher than 95 % when co-cultured with L929 cells. Diatom chitosan with 0.005 % could inhibit E. coli and S. aureus by >90 %. Considering the large-scale cultivation properties of diatom, the extraction of diatom chitosan based on alkalization freeze-thaw method will provide a viable solution for obtaining β-chitosan with homogeneity on a large scale.

Abstract
The fisheries and aquaculture industry are known for generating substantial waste or by-products, often underutilized, or relegated to low-value purposes. However, this overlooked segment harbors a rich repository of valuable bioactive materials of which have a broad-spectrum of high-value applications. As the blue economy gains momentum and fisheries expand, sustainable exploitation of these aquatic resources is increasingly prioritized. In this review, we present a comprehensive overview of technology-enabled methods for extracting and transforming aquatic waste into valuable biomaterials and their recent advances in regenerative medicine applications, focusing on marine collagen, chitin/chitosan, calcium phosphate and bioactive-peptides. We discuss the inherent bioactive qualities of these "waste-to-resource" aquatic biomaterials and identify opportunities for their use in regenerative medicine to advance healthcare while achieving the Sustainable Development Goals.

Sulphated glycosaminoglycan isolated from the edible slipper oyster Magallana bilineata (Röding, 1798) attenuates inflammatory cytokines on lipopolysaccharide-prompted macrophages. Nat Prod Res 2024:1-12. [PMID: 39001863 DOI: 10.1080/14786419.2024.2377311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 07/03/2024] [Indexed: 07/15/2024]
Abstract
The slipper oyster Magallana bilineata (Ostreidae) is considered as culinary delicacy among marine bivalves, and a sulphated glycosaminoglycan, 4,6-O-SO3-β-(1→3)-GalNAcp (unit A) and β-(1→4)-GlcAp (unit B) as principle structural motif containing laterally branched 4-O-SO3-β-glucopyranose (unit C) (MBP-3) was isolated from this species. Nuclear magnetic resonance (NMR), Fourier transform infra-red (FTIR), and mass spectroscopy techniques were used to characterise MBP-3. MBP-3 exhibited anti-inflammatory activities against inflammatory 5-lipoxygenase (IC50 0.11 mg mL-1) and cyclooxygenase-2 (IC50 0.12 mg mL-1) enzymes. MBP-3 (at 100 μg mL-1) showed effective downregulation against pro-inflammatory cytokines generation, namely interleukins-6, 1β, (IL-6, 1β) (1-1.7 pg mL-1) and tumour necrosis factor-α (TNF-α) (4 pg mL-1) along with substantial downregulation of ROS production in lipopolysaccharide (LPS)-inflamed cells. MBP-3 blocked the mRNA of NF-κB, cyclooxygenase-2 (COX-2), and other cytokines, in lipopolysaccharide-induced macrophages. The potential to constrain inflammatory cytokine production revealed its application to develop functional food to attenuate inflammation-associated disorders.

Abstract
Dipeptidyl peptidase is a crucial enzyme that regulates glucose metabolism by degrading incretins, such as glucagon-like-peptide-1, thereby reducing insulin secretion from the pancreatic β-cells. Consequently, dipeptidyl peptidase-IV inhibitors are an important remedial approach to moderate the hyperglycemic pathophysiology. A pyruvylated polysaccharide characterized as [→3)-4,6-O-(1-carboxyethylidene)-β-D-galp-(2SO3-)-(1→4)-3,6-α-L-AnGalp-(2OMe)-(1→], isolated from the marine macroalga Hydropuntia edulis, showed attenuation potential against dipeptidyl peptidase-IV (IC50 4.44 μM). The structure was elucidated using mass and one/two-dimensional nuclear magnetic resonance spectroscopic analyses of hydrolyzed polysaccharide besides glycosidic linkages obtained from partially methylated alditol acetate derivative. The isolated polysaccharide also revealed potential anti-carbolytic properties against α-amylase/α-glucosidase (IC50 45-47 μM). The results proved the candidacy of pyruvylated polysaccharide isolated from H. edulis as a potential therapeutic lead against hyperglycemia.

Abstract
Inflammation is one of the most significant causes of several chronic diseases, which includes the expression of cytokines activating immune cells to up-regulate the inflammatory cascade. Polysaccharides from marine macroalgae are promising anti-inflammatory agents because of their potential to attenuate inflammatory cytokines. The triangular sea bell Turbinaria decurrens (Sargassaceae) among marine macroalgae is ubiquitous in oceanic waters, and a sulfated polygalactofucan SPTd-2 [→3-(α-L-fucp-(2-OSO3-)-(1 → 4)-α-L-fucp-(3-OAc)-(1 → 4)-β-D-galp-(1→] was purified from the species. The studied polygalactofucan SPTd-2 exhibited anti-inflammatory activities against cyclooxygenase-2 (IC50 10.56 μM) and 5-lipoxygenase (IC50 3.36 μM) with a greater selectivity index (2.35) than ibuprofen (0.44), besides attenuating pro-inflammatory cytokine production, including tumor necrosis factor-α, transforming growth factor-β, interleukin-2, 1β, and interferon-γ. Quantitative real-time polymerase chain reaction displayed that SPTd-2 blocked the mRNA of interferon-γ and interleukin-2, in the human monocytic cell line THP-1. The results showed the potential of SPTd-2 to attenuate inflammation-associated disorders.
