Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Increased cerebrospinal fluid and plasma apoE glycosylation is associated with reduced levels of Alzheimer’s disease biomarkers

Alzheimer’s Research & Therapy
The apolipoprotein E (APOE) ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease (AD). ApoE is glycosylated with an O-linked Core-1 sialylated glycan at several sites; however, the impact and function of this glycosylation on

Palmitic Acid Promotes Antiviral Innate Immunity via ZDHHC20‐Mediated CMPK2 Palmitoylation

Advanced Science, EarlyView.
Metabolites have important functions in innate immune activation and regulation. Wang et al. uncover metabolic regulation of antiviral immunity through CMPK2 palmitoylation, which regulates CMPK2 mitochondrial localization and is promoted by ZDHHC20 but reversed by PPT1, inhibition of which antagonizes viral infection in mice.

Glycosylation in neuroinflammation: mechanisms, implications, and therapeutic strategies for neurodegenerative diseases

Translational Neurodegeneration
Neuroinflammation is a key pathological mechanism underlying neurodegenerative diseases, and intricately interacts with protein glycosylation. Emerging evidence suggests that aberrant glycosylation disrupts immune homeostasis, activates microglia, and ...

N-glycosylation of the protein disulfide isomerase Pdi1 ensures full Ustilago maydis virulence.

PLoS Pathogens, 2019
Fungal pathogenesis depends on accurate secretion and location of virulence factors which drive host colonization. Protein glycosylation is a common posttranslational modification of cell wall components and other secreted factors, typically required for

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Engineering Oncolytic Virus‐Armed Macrophages for Enhanced Cancer Immunotherapy

Advanced Science, EarlyView.
ZIFOA‐M is engineered by conjugating oncolytic adenovirus‐loaded ZIF‐8 nanoparticles onto macrophage surfaces via bioorthogonal chemistry. Upon tumor infiltration, the platform releases OA to downregulate CD47/CD24 on tumor cells, restoring macrophage phagocytosis.

Structural basis for coupling of protein transport and N-glycosylation at the mammalian endoplasmic reticulum

Science, 2018
A close-up view of oligosaccharyltransferase Many secretory and membrane proteins are modified through the attachment of sugar chains by N-glycosylation. Such modification is required for correct protein folding, targeting, and functionality.
