Gangliosides, glycosphingolipids with one or more N-acetyl-neuraminic acid groups, play essential roles in various cellular and biological processes, among them are cell signaling, neuronal development, cell-cell recognition and the modulation of immune response. Based on their multiple biological roles, the pharmacological utilization of gangliosides for the therapy of several clinical conditions is currently widely being explored but hampered by its limited water solubility. To increase the bioavailability of poorly water-soluble therapeutic agents, pharmaceutical nanocarriers such as liposomes have been developed over the last fifty years.

The major hurdle of xenotransplantation is the immune response triggered by human natural antibodies interacting with carbohydrate antigens on the transplanted animal organ. Specifically, terminal glycoprotein motifs such as galactose-α1,3-galactose (α-Gal) and N-glycolylneuraminic acid (Neu5Gc) are significant obstacles. Little is known about the abundance and compositions of asparagine-linked complex carbohydrates (N-glycans) carrying these motifs in mammalian organs.

Hereditary fructose intolerance (HFI) is characterized by liver damage and a secondary defect in N-linked glycosylation due to impairment of mannose phosphate isomerase (MPI). Mannose treatment has been shown to be an effective treatment in a primary defect in MPI (i.e.

Recently, it was described that neutral glycans can be distinguished from those containing sialic acid at the mercury electrode after modification with osmium(VI) N,N,N',N'-tetramethylethylenediamine (Os(VI)tem). Our work shows the possibility of studying glycans and glycoproteins at pyrolytic graphite electrodes depending on thepresence of sialic acid. Short glycans, glycans released from glycoproteins, and glycoproteins themselves yielded similar voltammetric responses after their modification by Os(VI)tem.

Background: To discover effective drugs for treating Influenza (a disease with high annual mortality), large amounts of recombinant neuraminidase (NA) with suitable catalytic activity are needed. However, the functional activity of the full-length form of this enzyme in the bacterial host (as producing cells with a low cost) in a soluble form is limited. Thus, in the present study, a truncated form of the neuraminidase (derived from California H1N1 influenza strain) was designed, then biosynthesized in Escherichia coli BL21 (DE3), Shuffle T7, and SILEX systems.
