Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

Advanced NanoBiomed Research, EarlyView.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.

The Role of Sialidases in the Development of Bacterial Vaginosis and their Use as Potential Markers in the Diagnosis of Vaginal Infections

Postępy Mikrobiologii
Bacterial vaginosis (BV) is an inflammatory condition of the vagina with a polyetiological origin, most commonly associated with an overgrowth of anaerobic bacteria such as Gardnerella vaginalis or Prevotella spp.

Streamlined gram-scale natural N-glycan production using reversible tagging after oxidative release of natural glycans

Communications Chemistry
The study of natural glycans is fundamental to modern glycomics; however, the functional analysis of these glycans is limited by their low natural abundance, structural heterogeneity, and the absence of efficient preparative-scale isolation methods. Here,

Minor acidic glycans: Review of focused glycomics methods

BBA Advances
Glycans are modified by acidic molecules, including sialic acid, sulfates, phosphates, and glucuronic acid, forming acidic glycans. Among these, sialylated glycans form major components of deuterostome glycomes, and their structure and function have been

Allosteric modulation by the fatty acid site in the glycosylated SARS-CoV-2 spike

eLife
The spike protein is essential to the SARS-CoV-2 virus life cycle, facilitating virus entry and mediating viral-host membrane fusion. The spike contains a fatty acid (FA) binding site between every two neighbouring receptor-binding domains.

Glycosylated extracellular vesicles released by glioblastoma cells are decorated by CCL18 allowing for cellular uptake via chemokine receptor CCR8

Journal of Extracellular Vesicles, 2018
Cancer cells release extracellular vesicles (EVs) that contain functional biomolecules such as RNA and proteins. EVs are transferred to recipient cancer cells and can promote tumour progression and therapy resistance.

Role of N-glycosylation in oral cancer [PDF]

, 2017
Oral squamous cell carcinoma represents more than 90% head and neck cancers with high incidence rate and morbidity. To date, little is known about the molecular mechanisms responsible for OSCC initiation and progression to advanced disease.

A Synergistic Inhibitor Development Strategy Against Human UDP‐Galactose‐4‐Epimerase

Angewandte Chemie International Edition, EarlyView.
The epimerase GalE is crucial for the biosynthesis of cancer‐relevant O‐GalNAc glycans. Here, we employ orthogonal, structurally enabled small molecule fragment screens to yield both covalent and non‐covalent inhibitors against GalE within no more than 22 elaborated compounds.

The Role of Glycans in Human Immunity—A Sweet Code

Molecules
Glycans on the surface of all immune cells are the product of diverse post-translational modifications (glycosylation) that affect almost all proteins and possess enormous structural heterogeneity.
