The Binding of Fibroblast Growth Factor 23 (FGF23) to FGF Receptor‐αKlotho Complex Increases Sinoatrial Electrical Activity

open access: yesActa Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim This study aims to investigate whether the Fibroblast Growth Factor 23 (FGF23) modulates the electrical activity of sinoatrial (SAN) cells. The canonical function of FGF23 is to regulate body phosphorus and calcium homeostasis by activating the FGF1 receptors (FGFR1)/α‐Klotho complex in the kidney and parathyroid glands.

Engineering Antibodies into Targeted Chimeras: From Recognition Modules to Programmable Degraders

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
Antibody can be engineered into diverse lysosome‐targeting chimeras that convert target recognition into active degradation. By coupling antibody binding with recruited receptors, encoded domains, conjugated ligands, or nanoparticle scaffolds, these antibody‐associated targeted chimeras (AbTACs) platforms direct extracellular and membrane proteins ...

Possible involvement of sialidase and sialyltransferase activities in a stage-dependent recycling of sialic acid in some organs of type 1 and type 2 diabetic rats

open access: yesFrontiers in Endocrinology
BackgroundType 1 (T1D) and type 2 (T2D) diabetes lead to an aberrant metabolism of sialoglycoconjugates and elevated free serum sialic acid (FSSA) level.

Analysis of the Role of N‐Linked Glycans on Human CD1d Molecules

open access: yesCell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT CD1d is a cell‐surface expressed glycoprotein that presents a variety of lipid and glycolipid antigens to invariant natural killer T‐cells (iNKT). We have examined the role of the N‐linked glycans on the human CD1d (hCD1d) in modulating the responses of iNKT cells using a combination of cell‐free, cell‐based assays and in silico analyses ...

Sialidase in rabbit blood [PDF]

open access: yesEuropean Journal of Biochemistry, 1994
Sialidase activities of rabbit blood cells and serum were measured. The leucocyte particulate fraction showed the highest specific activity of sialidase towards mixed gangliosides and sialyllactose, and the cytosolic fraction showed for fetuin. Predominant sialidase activity in the blood was detected in erythrocyte particulate fraction when mixed ...

Akkermansia muciniphila and Its Bioactive Derivatives: Emerging Regulators of Healthy Aging

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
The beneficial gut bacterium Akkermansia muciniphila (AKK) declines with age but is enriched in healthy centenarians. Supplementation of AKK extends healthspan and alleviates age‐related decline through direct host–microbe interactions and its bioactive derivatives, which collectively enhance gut barrier integrity, restore metabolic homeostasis ...

Different Transcriptomic Responses After Moderate and Severe Heat Shock in Trypanosoma cruzi Epimastigotes

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Trypanosoma cruzi undergoes heat stress during its life cycle. In this study, we performed a transcriptomic analysis of the heat shock response in epimastigotes from different T. cruzi strains. In both clone CL Brener and the Y strain, very few to no statistically significant variations were observed in the transcriptome at 37°C, whereas ...

Synthesis and Glycosidase Inhibition Studies of Novel Exoglycals Targeting GH3 Family Enzymes: Insights from Comparative Analysis with Macrolide Antibiotics

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
A series of structurally diverse exoglycals was synthesized using a modified Julia‐olefination approach from sugar‐derived precursors. These glycosidase transition‐state mimics were further diversified via CuAAC chemistry to yield triazole‐conjugated analogues.

New insights into the immunomodulatory potential of sialic acid on monocyte-derived dendritic cells

open access: yesCancer Immunology, Immunotherapy
Sialic acids at the cell surface of dendritic cells (DCs) play an important immunomodulatory role, and their manipulation enhances DC maturation, leading to heightened T cell activation.
