Abstract
BACKGROUND AND OBJECTIVE Yeasts have the remarkable capability to transform and integrate inorganic selenium into their cellular structures, thereby enhancing its bioavailability and reducing its toxicity. In recent years, yeasts have attracted attention as potential alternative sources of protein. METHODS This study explores the selenium accumulation potential of two less explored yeast strains, namely the probiotic Saccharomyces boulardii CCDM 2020 and Pichia fermentas CCDM 2012, in comparison to the extensively studied Saccharomyces cerevisiae CCDM 272. Our investigation encompassed diverse stress conditions. Subsequently, the selenized yeasts were subjected to an INFOGEST gastrointestinal model. The adherence and hydrophobicity were determined with undigested cells RESULTS: Stress conditions had an important role in influencing the quantity and size of selenium nanoparticles (SeNPs) generated by the tested yeasts. Remarkably, SeMet synthesis was limited to Pichia fermentas CCDM 2012 and S. boulardii CCDM 2020, with S. cerevisiae CCDM 272 not displaying SeMet production at all. Throughout the simulated gastrointestinal digestion, the most substantial release of SeCys2, SeMet, and SeNPs from the selenized yeasts occurred during the intestinal phase. Notably, exception was found in strain CCDM 272, where the majority of particles were released during the oral phase. CONCLUSION The utilization of both traditional and non-traditional selenized yeast types, harnessed for their noted functional attributes, holds potential for expanding the range of products available while enhancing their nutritional value and health benefits.

Abstract
Glycosphingolipids (GSLs) are comprised of glycans (oligosaccharides) linked to a lipid containing a sphingosine moiety. They are major membrane components in cells of most animals, and importantly, they also occur in parasitic protozoans and worms that infect people. While the endogenous functions of the GSLs in most parasites are elusive, many of these GSLs are recognized by antibodies in infected human and animal hosts, and thus, their structures, biosynthesis, and functions are of great interest. Such knowledge of GSLs could lead to new drugs and diagnostics for treating infections, as well as novel vaccine strategies. The diversity of GSLs recently identified in such infectious organisms and aspects of their immune recognition are major topics of this review. It is not intended to be exhaustive but to highlight aspects of GSL glycans in human parasites.

[PMID: 36581306 DOI: 10.1016/j.micpath.2022.105961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 12/22/2022] [Accepted: 12/22/2022] [Indexed: 12/28/2022]
Abstract
Swine dysentery caused by Brachyspira hyodysenteriae is a disease present worldwide with an important economic impact on the farming business, resulting in an increased use of antibiotics. In the present study, we investigated the binding of B. hyodysenteriae to glycosphingolipids from porcine small intestinal epithelium in order to determine the glycosphingolipids involved in B. hyodysenteriae adhesion. Specific interactions between B. hyodysenteriae and two non-acid glycosphingolipids were obtained. These binding-active glycosphingolipids, were characterized by mass spectrometry as lactotetraosylceramide (Galβ3GlcNAcβ3Galβ4Glcβ1Cer) and the B5 glycosphingolipid (Galα3Galβ4GlcNAcβ3Galβ4Glcβ1Cer). Comparative binding studies using structurally related reference glycosphingolipids showed that B. hyodysenteriae binding to lactotetraosylceramide required an unsubstituted terminal Galβ3GlcNAc sequence, while for binding to the B5 pentaosylceramide the terminal Galα3Galβ4GlcNAc sequence is the minimum element recognized by the bacteria. Binding of Griffonia simplicifolia IB4 lectin to pig colon tissue sections from healthy control pig and B. hyodysenteriae infected pigs showed that in the healthy pigs the Galα3Gal epitope was mainly present in the lamina propria. In contrast, in four out of five pigs with swine dysentery there was an increased expression of Galα3Gal in the goblet cells and in the colonic crypts, where B. hyodysenteriae also was present. The one pig that had recovered by the time of necropsy had the Galα3Gal epitope only in the lamina propria. These data are consistent with a model where a transient increase in the carbohydrate sequence recognized by the bacteria occur in colonic mucins during B. hyodysenteriae infection, suggesting that the mucins may act as decoys contributing to clearance of the infection. These findings may lead to novel strategies for treatment of B. hyodysenteriae induced swine dysentery.
