Structure of a gly- colipid reacting with monoclonal IgM in neuropathy and with HNK-1. Biochem Biophys Res Commun 1985;128:383-8.Chou D. K. H., Ilyas A. A., Evans J. E., Quarles R. H. and Jungalwala F. B. (1985) Structure of a glycolipid reacting with monoclonal IgM in ...
Most Gram-negative bacteria are surrounded by a glycolipid called lipopolysaccharide (LPS), which forms a barrier to hydrophobic toxins and, in pathogenic bacteria, is a virulence factor. During LPS biosynthesis, a membrane-associated glycosyltransferase (LpxB) forms a tetra-acylated disaccharide that ...
The stratum basale is a single layer of cells primarily made of basal cells. Abasal cellis a cuboidal-shaped stem cell that is a precursor of the keratinocytes of the epidermis. All of the keratinocytes are produced from this single layer of cells, which are constantly going through mitosis ...
Outer membrane vesicles (OMVs), shed by Gram-negative bacteria, are spherical nanostructures that play a pivotal role in bacterial communication and host-pathogen interactions. Comprising an outer membrane envelope and encapsulating a variety of bioactive molecules from their progenitor bacteria, OMVs faci...
Capsular polysaccharides are important virulence factors in pathogenic bacteria. Characterizing the structural components and biosynthetic pathways for these polysaccharides is key to our ability to design vaccines and other preventative therapies that t
They are classified into two groups: wall teichoic acids (WTAs), which are covalently linked to the PG molecule, and lipoteichoic acids (LTAs), which are anchored in the cytoplasmic membrane with a glycolipid moiety. WTAs may constitute up to half of cell wall total dry weight in certain ...
这些糖链有时会与蛋白质连接形成糖蛋白(glycoprotein),有时与脂肪连接形成糖脂(glycolipid)。 胆固醇 Cholesterol 胆固醇在细胞膜中的作用是调节磷脂层的流动性(flexibility)。(help buffer the fluidity of the membrane) 使细胞膜更稳定 使细胞膜在胞吞胞吐(endocytosis,exocytosis)时可以pinch in and out 限制极性分子...

The myelin sheath is highly enriched in glycosphingolipids, with galactosylceramide (GalCer)2 and its sulfated derivative sulfatide representing the major glycolipid components. GalCer is generated from a ceramide-based precursor composed of a long chain base (LCB) moiety that is derived from ...
which are found in uropathogenicEscherichia coli, and enable those bacteria to adhere to endothelial cell surfaces22,23. Cell-surface attachment is mediated by specialised adhesins that cap the filaments’ distal termini and are selective to sugar residues in glycolipid receptors on the host’s cell...
