The wondrous and worrying diversity of the N-glycans of Chlorella food supplements

The paper analyzes N-glycan diversity in Chlorella supplements, finding mismatches between product labels and glycan patterns, highlighting concerns about product authenticity.

Tumor sialylation controls effective anti-cancer immunity in breast cancer

This study shows that tumor sialylation suppresses anti-cancer immunity in breast cancer by altering immune cell interactions and checkpoint ligands, and that inhibiting sialylation enhances immune response and therapy effectiveness.

Non-targeted isomer-sensitive N-glycome analysis reveals new layers of organ-specific diversity in mice.

The paper presents a method for analyzing N-glycome diversity in mice tissues, revealing tissue-specific glycosylation patterns and non-canonical structures.

Time grid-based isomer specific N-glycan analysis and detection of bisecting Lewis X in human brain

The paper introduces a method using stable isotope labeled reference N-glycans to resolve isomeric structures in complex mixtures, revealing new isomers in human brain N-glycans.
