The origins of plasmacytoid dendritic cells have long been controversial and progenitors exclusively committed to this lineage have not been described. We show here that the fate of hematopoietic progenitors is determined in part by their surface levels of 9-O-acetyl sialic acid. Pro-plasmacytoid dendritic cells were identified as lineage negative 9-O-acetyl sialic acid low progenitors that lack myeloid and lymphoid potential but differentiate into pre-plasmacytoid dendritic cells. The latter cells are also lineage negative, 9-O-acetyl sialic acid low cells but are exclusively committed to the plasmacytoid dendritic cell lineage. Levels of 9-O-acetyl sialic acid provide a distinct way to define progenitors and thus facilitate the study of hematopoietic differentiation.

Sialic acid is a family of N- and O-substitutions of neuraminic acid. Plasma or serum sialic acid has been established as a potential disease marker. For example, the presence of 9-O-acetyl on the sia...
To compare the sialic acid (SA) levels in saliva among periodontitis-affected, gingivitis and control patients.
A species barrier for the influenza A virus is the differential expression of sialic acid, which can either be α2,3-linked for avians or α2,6-linked for human viruses. The influenza A virus hosts al...
Sialic acids cap the glycans of cell surface glycoproteins and glycolipids. They are involved in a multitude of biological processes and aberrant sialic acid expression is associated with several path...
Sialylation of glycoproteins and glycolipids is important for biological processes such as cellular communication, cell migration and protein function. Biosynthesis of CMP-sialic acid, the essential s...
This study is aimed at assessing the impact of short-term (3 days) exogenous sialic acid supplementation on endogenous biomarkers of sialic acid metabolism in NANS deficient patients.
Sialic acid (SA) is the generic term given to a family of acetylated derivatives of neuraminic acid. SA is a 9 carbon monosaccharide. An important function of host SA is to regulate innate...

An open label pilot study will determine the effect of the amino acid nutritional supplement acetyl-L-carnitine (ALC) on pain, quality of life, well-being, and serum pro-inflammatory media...
Autosomal recessive neurodegenerative disorders caused by lysosomal membrane transport defects that result in accumulation of free sialic acid (N-ACETYLNEURAMINIC ACID) within the lysosomes. The two main clinical phenotypes, which are allelic variants of the SLC17A5 gene, are ISSD, a severe infantile form, or Salla disease, a slowly progressive adult form, named for the geographic area in Finland where the kindred first studied resided.
A family of SIALIC ACID binding proteins found in vertebrate species. They are transmembrane proteins which act as cell surface receptors for a variety of sialylated GLYCOCONJUGATES. While a subset of siglec protein subtypes are evolutionarily conserved between mammalian species, there are many others that are species specific.
Enzyme that catalyzes the final step of fatty acid oxidation in which ACETYL COA is released and the CoA ester of a fatty acid two carbons shorter is formed.
A sialic acid binding lectin that was originally identified as an adhesion molecule for inflammatory MACROPHAGES and activated MONOCYTES. This protein is the largest known siglec subtype and contains 16 immunoglobulin C2-set domains. It plays a role in cell to cell interactions and interactions with BACTERIA.
A lectin and cell adhesion molecule found in B-LYMPHOCYTES. It interacts with SIALIC ACIDS and mediates signaling from B-CELL ANTIGEN RECEPTORS.
