Cloning and expression of porcine β1,4 N-acetylgalactosaminyl transferase encoding a new xenoreactive antigen [PDF]
Xenograft rejection of pigs organs with an engineered mutation in the GGTA-1 gene (GTKO) remains a predominantly antibody mediated process which is directed to a variety of non-Gal protein and carbohydrate antigens.

N-Glycolylneuraminic Acid in Animal Models for Human Influenza A Virus
The first step in influenza virus infection is the binding of hemagglutinin to sialic acid-containing glycans present on the cell surface. Over 50 different sialic acid modifications are known, of which N-acetylneuraminic acid (Neu5Ac) and N ...

Mice lacking sialyltransferase ST3Gal-II develop late-onset obesity and insulin resistance [PDF]
Sialyltransferases are a family of 20 gene products in mice and humans that transfer sialic acid from its activated precursor, CMP-sialic acid, to the terminus of glycoprotein and glycolipid acceptors.

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 ...

Recognition of specific sialoglycan structures by oral streptococci impacts the severity of endocardial infection. [PDF]
Streptococcus gordonii and Streptococcus sanguinis are primary colonizers of the tooth surface. Although generally non-pathogenic in the oral environment, they are a frequent cause of infective endocarditis.

Potential deleterious role of anti‐Neu5Gc antibodies in xenotransplantation
AbstractHuman beings do not synthesize the glycolyl form of the sialic acid (Neu5Gc) and only express the acetylated form of the sugar, whereas a diet‐based intake of Neu5Gc provokes a natural immunization and production of anti‐Neu5Gc antibodies in human serum.

Membrane-enclosed multienzyme (MEME) synthesis of 2,7-anhydro-sialic acid derivatives [PDF]
Naturally occurring 2,7-anhydro-alpha-N-acetylneuraminic acid (2,7-anhydro-Neu5Ac) is a transglycosylation product of bacterial intramolecular trans-sialidases (IT-sialidases).

N-Glycolylneuraminic acid (Neu5Gc)-terminated glycans are present in all animal cells/tissues that are already used in the clinic such as bioprosthetic heart valves (BHV) as well as in those that potentially will be xenografted in the future to overcome ...

Comparison of sialic acid content in bovine and buffalo milk and meat
Animal-origin food, such as meat and milk, are important sources of sialic acids (SIAs) with relevant implications for human health. Two significant SIAs in mammals are N-acetyl-neuraminic acid (Neu5Ac) and N- glycolylneuraminic acid (Neu-5Gc).

Immune Response Modulation by Tumor-Secreted Glycosphingolipids [PDF]
Although originally considered merely structural components of cellular membranes, glycosphingolipids (GSL) arenow recognized as having critical effects on cellular physiology, including proliferation, differentiation, viraltransformation and ontogenesis.
