چکیده

Histo-blood group antigens (HBGAs) are important binding factors for norovirus infections. We show that two human milk oligosaccharides, 2'-fucosyllactose (2'FL) and 3-fucosyllactose (3FL), could block norovirus from binding to surrogate HBGA samples. We found that 2'FL and 3FL bound at the equivalent HBGA pockets on the norovirus capsid using X-ray crystallography. Our data revealed that 2'FL and 3FL structurally mimic HBGAs. These results suggest that 2'FL and 3FL might act as naturally occurring decoys in humans.

Oligosaccharides and glycoconjugates of human milk could protect breast-fed infants against norovirus intestinal infections

Background: Noroviruses are, after rotaviruses, the most common cause of nonbacterial intestinal infections in children. It has been observed a lower incidence of norovirus gastroenteritis in breast-fed compared to formula-fed infants. Effective vaccines against noroviruses are not yet available, enhancing the interest of the protective mechanisms elicited by human milk. Human milk contains a w...

Human Norovirus Interactions with Histo-Blood Group Antigens and Human Milk Oligosaccharides.

Human noroviruses interact with both human histo-blood group antigens (HBGAs) and human milk oligosaccharides (HMOs). The former are believed to be important for a virus infection, while the latter might act as natural decoys in the host during an infection. However, certain noroviruses are known to bind poorly to HBGAs and yet still cause infections; some interact with numerous HBGA types but ...

Bovine milk as a source of functional oligosaccharides for improving human health.

Human milk oligosaccharides are complex sugars that function as selective growth substrates for specific beneficial bacteria in the gastrointestinal system. Bovine milk is a potentially excellent source of commercially viable analogs of these unique molecules. However, bovine milk has a much lower concentration of these oligosaccharides than human milk, and the majority of the molecules are sim...

Protection from Viral Infections by Human Milk Oligosaccharides: Direct Blockade and Indirect Modulation of Intestinal Ecology and Immune Reactions

Sugar-lectin interactions play an important role in viral infections. Many viruses, such as human immunodeficiency virus (HIV), Ebola, dengue, cytomegalovirus, and hepatitis C, possess glycans that recognize C-type lectins, especially CD209 (DC-SIGN), for infection. Other viruses possess lectins on their surfaces that recognize glycan epitopes on human epithelial cells for infection. Human and ...

Structural basis for the interaction between human milk oligosaccharides and the bacterial lectin PA-IIL of Pseudomonas aeruginosa.

One of the mechanisms contributing to the protection by breast-feeding of the newborn against enteric diseases is related to the ability of human milk oligosaccharides to prevent the attachment of pathogenic bacteria to the duodenual epithelium. Indeed, a variety of fucosylated oligosaccharides, specific to human milk, form part of the innate immune system. In the present study, we demonstrate ...
