Deletion of ASAH2 in intestinal epithelial cells induces the accumulation of ganglioside GD3 via regulating ST8SIA1. GD3 is identified as the glycolipid ligand for the inhibitory receptor Siglec‐E on macrophages. GD3/Siglec‐E ligation polarizes macrophages and promotes the proliferation of colonic ST2+ T regulatory cells via the induction of IL‐33. The

Atomic Resolution Structure of the Oncolytic Parvovirus LuIII by Electron Microscopy and 3D Image Reconstruction. [PDF]
LuIII, a protoparvovirus pathogenic to rodents, replicates in human mitotic cells, making it applicable for use to kill cancer cells. This virus group includes H-1 parvovirus (H-1PV) and minute virus of mice (MVM).

DNA Nanostructure‐Templated Multivalency Enables Broad‐Spectrum Virus Inhibition
A honeycomb‐shaped DNA nanostructure is introduced that organizes nanobodies or aptamers into trimeric clusters mirroring the native hemagglutinin arrangement on influenza viruses. This geometry‐matched multivalency enhances binding avidity by up to 1000‐fold, resulting in robust, broad‐spectrum viral neutralization and a 30–55% improvement in host ...

Synthesis of N-Glycolylneuraminic Acid (Neu5Gc) and Its Glycosides. [PDF]
Sialic acids constitute a family of negatively charged structurally diverse monosaccharides that are commonly presented on the termini of glycans in higher animals and some microorganisms.

A CD169+ macrophage‐targeted immunomodulator (G‐LNP@S‐D) is developed to co‐deliver a SHP2 inhibitor and STING agonist, thereby restoring phagocytic function, enhancing antigen presentation by CD169+ macrophages, and promoting T cell priming to eradicate lymphatic metastasis.

Possible Influences of Endogenous and Exogenous Ligands on the Evolution of Human Siglecs
Sialic acids, a group of acidic sugars abundantly expressed in the tissues of deuterostome animals but rarely found in microbes, serve as a “signature of self” for these animals. Cognate sensors for sialic acids include Siglecs, a family of transmembrane

Presence of N-acetylneuraminic acid in the lung during postnatal development
Sialic acids, particularly N-acetylneuraminic acid (Neu5Ac), are present as terminal components of rich and complex oligosaccharide chains, which are termed glycans, and are exhibited on the cell surfaces, especially on epithelial cells.

GlycoChat Uncovers Glycan–Lectin Circuits in the Tumor Microenvironment of Pancreatic Cancer
Aberrant glycosylation drives cancer progression, yet its role in the tumor microenvironment remains unclear. We developed GlycoChat to map glycan–lectin circuits at single‐cell resolution. We discovered that cancer cells induce immunosuppressive macrophage differentiation and impair phagocytosis through interactions with CLEC10A and SIGLEC3 ...
