Capsular Sialyltransferase Specificity Mediates Different Phenotypes in Streptococcus suis and Group B Streptococcus

open access: yesFrontiers in Microbiology, 2018
The capsular polysaccharide (CPS) represents a key virulence factor for most encapsulated streptococci. Streptococcus suis and Group B Streptococcus (GBS) are both well-encapsulated pathogens of clinical importance in veterinary and/or human medicine and

Blood-Borne ST6GAL1 Regulates Immunoglobulin Production in B Cells

open access: yesFrontiers in Immunology, 2020
Humoral immunity is an effective but metabolically expensive defense mechanism. It is unclear whether systemic cues exist to communicate the dynamic need for antigen presentation and immunoglobulin production.

Synthesis of N-Glycolylneuraminic Acid (Neu5Gc) and Its Glycosides. [PDF]

open access: yes, 2019
Sialic acids constitute a family of negatively charged structurally diverse monosaccharides that are commonly presented on the termini of glycans in higher animals and some microorganisms.

Systemic ST6Gal-1 Is a Pro-survival Factor for Murine Transitional B Cells

open access: yesFrontiers in Immunology, 2018
Humoral immunity depends on intrinsic B cell developmental programs guided by systemic signals that convey physiologic needs. Aberrant cues or their improper interpretation can lead to immune insufficiency or a failure of tolerance and autoimmunity.

Sialylation of vasorin by ST3Gal1 facilitates TGF-β1-mediated tumor angiogenesis and progression. [PDF]

open access: yes, 2019
ST3Gal1 is a key sialyltransferase which adds α2,3-linked sialic acid to substrates and generates core 1 O-glycan structure. Upregulation of ST3Gal1 has been associated with worse prognosis of breast cancer patients.

Marine Bacterial Sialyltransferases

open access: yesMarine Drugs, 2010
Sialyltransferases transfer N-acetylneuraminic acid (Neu5Ac) from the common donor substrate of these enzymes, cytidine 5’-monophospho-N-acetylneuraminic acid (CMP-Neu5Ac), to acceptor substrates.

Glycosylation of glycolipids in cancer: basis for development of novel therapeutic approaches [PDF]

open access: yes, 2013
Altered networks of gene regulation underlie many pathologies, including cancer. There are several proteins in cancer cells that are turned either on or off, which dramatically alters the metabolism and the overall activity of the cell, with the complex ...

Glia-neuron coupling via a bipartite sialylation pathway promotes neural transmission and stress tolerance in Drosophila

open access: yeseLife, 2023
Modification by sialylated glycans can affect protein functions, underlying mechanisms that control animal development and physiology. Sialylation relies on a dedicated pathway involving evolutionarily conserved enzymes, including CMP-sialic acid ...

Distribution of glycan motifs at the surface of midgut cells in the cotton leafworm (Spodoptera littoralis) demonstrated by lectin binding [PDF]

open access: yes, 2017
Glycans are involved in many biological phenomena, including signal transduction, cell adhesion, immune response or differentiation. Although a few papers have reported on the role of glycans in the development and proper functioning of the insect midgut,

Free and bound forms of sialic acid in blood plasma of patients with chronic lymphocytic leukemia

open access: yesRegulatory Mechanisms in Biosystems, 2015
The level of free and bound forms of sialic acids (SА) was investigated in chronic lymphocytic leukemia (CLL) and at different stages of receiving chemotherapy.
