Galactose starvation in a bloodstream form Trypanosoma brucei UDP-glucose 4'-epimerase conditional null mutant [PDF]

, 2006
Galactose metabolism is essential for the survival of Trypanosoma brucei, the etiological agent of African sleeping sickness. T. brucei hexose transporters are unable to transport galactose, which is instead obtained through the epimerization of UDP ...

Fluorescent Staining of Glycoproteins on Polyvinylidene Difluoride Membrane with 8-Aminonaphthalene-1,3,6-Trisulfonate

BioTechniques, 2001
Here, we describe a simple and sensitive method that allows fluorescent detection of glycoproteins on polyvinylidene difluoride (PVDF) membrane. We used periodic acid oxidation of carbohydrate chains of glycoproteins and fluorescent labeling with 8 ...

Tomato spotted wilt virus glycoproteins induce the formation of endoplasmic reticulum- and Golgi-derived pleomorphic membrane structures in plant cells [PDF]

, 2008
Tomato spotted wilt virus (TSWV) particles are spherical and enveloped, an uncommon feature among plant infecting viruses. Previous studies have shown that virus particle formation involves the enwrapment of ribonucleoproteins with viral glycoprotein ...

Lipidomimetic Compounds Act as HIV-1 Entry Inhibitors by Altering Viral Membrane Structure

Frontiers in Immunology, 2018
The envelope of Human Immunodeficiency Virus type 1 (HIV-1) consists of a liquid-ordered membrane enriched in raft lipids and containing the viral glycoproteins.

Human galectin-1 and galectin-3 promote Tropheryma whipplei infection

Gut Microbes, 2021
Tropheryma whipplei, is an actinobacterium that causes different infections in humans, including Whipple’s disease. The bacterium infects and replicates in macrophages, leading to a Th2-biased immune response. Previous studies have shown that T. whipplei

Herpesvirus glycoproteins undergo multiple antigenic changes before membrane fusion.

PLoS ONE, 2012
Herpesvirus entry is a complicated process involving multiple virion glycoproteins and culminating in membrane fusion. Glycoprotein conformation changes are likely to play key roles.

Host antiviral factors hijack furin to block SARS-CoV-2, ebola virus, and HIV-1 glycoproteins cleavage

Emerging Microbes and Infections, 2023
Viral envelope glycoproteins are crucial for viral infections. In the process of enveloped viruses budding and release from the producer cells, viral envelope glycoproteins are presented on the viral membrane surface as spikes, promoting the virus's next-

Fusion of secretory vesicles isolated from rat liver [PDF]

, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.
