Molecular Structural Analysis of Porcine CMAH–Native Ligand Complex and High Throughput Virtual Screening to Identify Novel Inhibitors

Pathogens, 2023
Porcine meat is the most consumed red meat worldwide. Pigs are also vital tools in biological and medical research. However, xenoreactivity between porcine’s N-glycolylneuraminic acid (Neu5Gc) and human anti-Neu5Gc antibodies poses a significant ...

N-glycolylneuraminic acid binding of avian H7 influenza A viruses [PDF]

, 2020
Abstract Influenza A viruses initiate infection by binding to glycans with terminal sialic acids present on the cell surface. Hosts of influenza A viruses variably express two major forms of sialic acid, N-acetylneuraminic acid (NeuAc) and N-glycolylneuraminic acid (NeuGc).

Specificity and utility of SubB2M, a new N-glycolylneuraminic acid lectin

Biochemical and Biophysical Research Communications, 2018
The B subunit of the subtilase cytotoxin (SubB) recognises N-glycolylneuraminic acid (Neu5Gc) containing glycans, the most prominent form of aberrant glycosylation in human cancers. We have previously engineered SubB by construction of a SubBΔS106/ΔT107 mutant (SubB2M) for greater specificity and enhanced recognition of Neu5Gc containing glycans.

Sperm and Egg Jelly Coat from Sea Urchin Lytechinus variegatus Collected in Rio de Janeiro Contain Distinct Sialic Acid-Rich Polysaccharides

Brazilian Archives of Biology and Technology, 2015
This work found the occurrence of a distinct sialic acid-rich polysaccharide in the sperm surface of the sea urchin Lytechinus variegatus, which differed significantly from a similar molecule found in the egg jelly.

Fucosylation limits ADCC in clinically used anti‐RhD monoclonal antibodies

Transfusion, EarlyView.
Abstract Background Haemolytic disease of the fetus and newborn (HDFN) is caused by maternal alloantibodies, often targeting the D antigen on fetal red blood cells. Maternal immunization is preventable with timely administration of anti‐D polyclonal antibodies (pAbs).

Sensitive and specific detection of the non-human sialic Acid N-glycolylneuraminic acid in human tissues and biotherapeutic products.

PLoS ONE, 2009
BackgroundHumans are genetically defective in synthesizing the common mammalian sialic acid N-glycolylneuraminic acid (Neu5Gc), but can metabolically incorporate it from dietary sources (particularly red meat and milk) into glycoproteins and glycolipids ...

Mechanism of Uptake and Incorporation of the Non-human Sialic Acid N-Glycolylneuraminic Acid into Human Cells* [PDF]

Journal of Biological Chemistry, 2005
N-Glycolylneuraminic acid (Neu5Gc) is a widely expressed sialic acid in mammalian cells. Although humans are genetically deficient in producing Neu5Gc, small amounts are present in human cells in vivo. A dietary origin was suggested by human volunteer studies and by observing that free Neu5Gc is metabolically incorporated into cultured human carcinoma ...

Reduced Complement and Granulocyte Activation by α‐Gal Knockout Porcine Pericardium for Bioprosthetic Heart Valves: A Pilot Hemocompatibility Study

Journal of Biomedical Materials Research Part A, Volume 114, Issue 7, July 2026.
Genetically modified, α‐Gal‐depleted porcine pericardium and wild type tissues are investigated for hemocompatibility and material properties such as mechanobiology and ECM profile to carve out the suitability of the gene‐modified tissue as material for biological heart valve prostheses. ABSTRACT Xenogeneic pericardium is the main source for biological

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 829-850, July/August 2026.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...
