Combining Cryogenic Infrared Spectroscopy with Selective Enzymatic Cleavage for Determining Glycan Primary Structure

Thomas Rizzo, Robert Paul Pellegrinelli, Eduardo Carrascosa Casado

Given the biological relevance and intrinsic structural complexity of glycans, increasing efforts are being directed towards developing a general glycan database that includes information from different analytical methods. As recently demonstrated, cryogen ...

Initial Step of Virus Entry: Virion Binding to Cell-Surface Glycans

Laurent Gillet, Christian Sieben

Virus infection is an intricate process that requires the concerted action of both viral and host cell components. Entry of viruses into cells is initiated by interactions between viral proteins and cell-surface receptors. Various cell-surface glycans func ...

Folding and Endocytosis of Anthrax Toxin Receptors

Bacillus anthracis is the causative agent of the infectious disease anthrax. The disease is caused after taking up the spores by either inhalation, ingestion or through skin lesion. They then germinate inside the body and start secreting the tripartite ant ...

Differential dependence on N-glycosylation of anthrax toxin receptors CMG2 and TEM8

Françoise Gisou van der Goot Grunberg, Julie Deuquet Ariosa

ANTXR 1 and 2, also known as TEM8 and CMG2, are two type I membrane proteins, which have been extensively studied for their role as anthrax toxin receptors, but with a still elusive physiological function. Here we have analyzed the importance of N-glycosyl ...

Asparagine-linked glycans (N-glycans) are displayed on the majority of proteins synthesized in the endoplasmic reticulum (ER). Removal of the outermost glucose residue recruits the lectin chaperone malectin possibly involved in a first triage of defective ...

Optofluidic-tunable color filters and spectroscopy based on liquid-crystal microflows

Demetri Psaltis, Andreas Vasdekis, Julien Cuennet

The integration of color filters with microfluidics has attracted substantial attention in recent years, for on-chip absorption, fluorescence, or Raman analysis. We describe such tunable filters based on the micro-flow of liquid crystals. The filter operat ...

Serum antiglycan antibody detection of nonmucinous ovarian cancers by using a printed glycan array

Darlene Goldstein

Epithelial ovarian cancer has the highest mortality rate among gynecological cancers. Altered glycosylation is associated with oncogenic transformation producing tumor-associated carbohydrate antigens. We investigated the potential of natural occurring ant ...
