Sialic Acids as Receptors for Pathogens. [PDF]

open access: yesBiomolecules, 2021
Carbohydrates have long been known to mediate intracellular interactions, whether within one organism or between different organisms. Sialic acids (Sias) are carbohydrates that usually occupy the terminal positions in longer carbohydrate chains, which ...

Sialometabolism in Brain Health and Alzheimer’s Disease [PDF]

open access: yesFrontiers in Neuroscience, 2022
Sialic acids refer to a unique family of acidic sugars with a 9-carbon backbone that are mostly found as terminal residues in glycan structures of glycoconjugates including both glycoproteins and glycolipids.

Unraveling the impact of sialic acids on the immune landscape and immunotherapy efficacy in pancreatic cancer. [PDF]

open access: yesJ Immunother Cancer, 2023
Background Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers. Despite the successful application of immune checkpoint blockade in a range of human cancers, immunotherapy in PDAC remains unsuccessful.

The Sialic Acids [PDF]

open access: hybridJournal of Biological Chemistry, 1966
Sialic acid 9-phosphate synthetase, an enzyme that condenses phosphoenolpyruvate with N-acyl- d -mannosamine 6-phosphate to yield sialic acid 9-phosphate and inorganic phosphate, was purified approximately 800-fold from extracts of hog submaxillary gland. The enzyme was specific for the indicated substrates, and the available data suggest that a single
