Anti-Galα1,3Galβ-R natural antibodies are responsible for hyperacute rejection in pig-to-primate xenotransplantation. Although the generation of pigs lacking the α1,3galactosyltransferase (GalT) has overcome hyperacute rejection, antibody-mediated rejection is still a problem. It is possible that other enzymes synthesize antigens similar to

Delayed immediate-type allergy to innards and red meat can be mediated by IgE antibodies to galactose-α-1, 3-galactose (α-Gal). Apart from humans and Old World apes, α-Gal is ubiquitously expressed in glycoproteins and glycolipids. Thus, as α-Gal is immunogenic for humans

As much as one percent of antibodies in human plasma are reported to be specific for the non-human disaccharide structure αGal. Various microbes express αGal. However, the implications of anti-αGal antibodies for the anti-microbial defenses are poorly established. With the
