ST6GAL1‐Mediated Sialylation Stabilizes PD‐L1 and Drives Immunosuppressive Tumor Microenvironment in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
ST6GAL1 plays a critical role in tumor progression and immune regulation in colorectal cancer (CRC). Its depletion significantly suppresses the malignant phenotype of CRC cells and enhances the efficacy of anti‐PD‐L1 therapy. High ST6GAL1 expression promotes an immune‐activated tumor microenvironment (TME), characterized by increased infiltration of ...

Membrane glycomics reveal heterogeneity and quantitative distribution of cell surface sialylation. [PDF]

open access: yes, 2018
Given that unnatural sugar expression is metabolically achieved, the kinetics and disposition of incorporation can lend insight into the temporal and localization preferences of sialylation across the cell surface.

HERV‐K TM Subunit Elicits CD8+ T Cell Anergy and Tumor Immune Evasion via Targeting CD3 Coreceptor ε in AML and PDAC

open access: yesAdvanced Science, EarlyView.
Novel viral immune checkpoint K‐TM subunit is aberrantly expressed in CD8+ T cells and enriched in sera of cancer patients, inducing CD8+ T cell anergy and eliciting potent tumor immune escape in mouse model. Mechanistically, K‐TM directly targets and induces the phosphorylation of CD3ε receptor.

Calhm6 Governs Macrophage Polarization Through Chp1‐Camk4‐Creb1 Axis and Ectosomal Delivery in Inflammatory Responses

open access: yesAdvanced Science, EarlyView.
Calhm6 drives M2 macrophage polarization via the Chp1‐Camk4‐Creb1 axis, suppressing inflammation through calcium‐dependent ectosomal delivery. Calhm6 deficiency enhances M1 responses, boosting bactericidal activity but exacerbating tissue damage. LPS/IFNγ upregulate Calhm6 via Irf1, while IL‐4/Stat6 inhibits it, balancing immune outcomes.

The MX-Helix of Muscle nAChR Subunits Regulates Receptor Assembly and Surface Trafficking. [PDF]

open access: yes, 2020
Nicotinic acetylcholine receptors (AChRs) are pentameric channels that mediate fast transmission at the neuromuscular junction (NMJ) and defects in receptor expression underlie neuromuscular disorders such as myasthenia gravis and congenital myasthenic ...

Pathogenic Variants in Fucokinase Cause a Congenital Disorder of Glycosylation [PDF]

open access: yes, 2018
FUK encodes fucokinase, the only enzyme capable of converting L-fucose to fucose-1-phosphate, which will ultimately be used for synthesizing GDP-fucose, the donor substrate for all fucosyltransferases.
