anti-human CD17 FITC-conjugated, Clone HIP10
Description
CD17, lactosylceramide, is an ubiquitous glycosphingolipid with uncharged disaccharide headgroup, highly enriched in lipid raftderived structures. Besides playing a pivotal role in the biosynthesis of complex glycosphingilipids, lactosylceramide is involved in cellcell and cellmatrix interactions and in signaling events linked to cell differentiation, development, apoptosis and oncogenesis. Lactosylceramide regulates integrin functions and production of nitric oxide. Its expression defines successive stages in the maturation of myeloid cells. Lactosylceramide (LaCer) is present on peripheral blood granulocytes including basophils, monocytes, platelets and a subset of B cells (40-80% CD19+). In tissues, CDw17 is found on tonsillar dendritic cells, epithelial cells, intestinal epithelium and endothelial. CDw17 antigen may play a role in phagocytosis.
Properties
The monoclonal antibody ADG5013/L (clone HIP10) is a murine monoclonal antibody, subclass IgM.
The antibody recognizes CDw17, a membrane lipid moiety lactosylceramide expressed on granulocytes, monocytes and platelets.
Conjugation
The purified antibody is conjugated with Fluoresceinisothiocyanate (FITC) under optimum conditions. The reagent is adjusted for direct use. No reconstitution is necessary

Lactosylceramide interacts with and activates cytosolic phospholipase A2α.

CD17 also known as lactosylceramide (LacCer) is a bioactive lipid in various cell physiological processes. The authors provided evidence that LacCer (CD17) is a direct activator of cytosolic phospholipase A2α (cPLA2α).

Sphingolipids in atherosclerosis and vascular biology.
Chatterjee S
In his review Chatterjee refers to the observation that sphingolipids and their metabolic products have second-messenger functions in a variety of cellular signaling pathways. Lactosylceramide (LacCer; CD17) mediates the tumor necrosis factor-alpha (TNF-alpha)-induced nuclear factor-kappaB expression and intercellular adhesion molecule (ICAM-1) expression in vascular endothelial cells. Moreover, LacCer (CD17) also stimulates the expression of CD11/CD8, or Mac-1, on the surface of human neutrophils. This may promote the adhesion of neutrophils or monocytes to the endothelial cell surface and initiate the process of atherosclerosis. Moreover, there is evidence that plaque stability may be negatively affected by LacCer (CD17). The author concludes that “The findings … indicate an important role for sphingolipids in vascular biology and provide an exciting opportunity for further research in vascular disease and atherosclerosis.”

Sphingolipid composition of human platelets.
Tao RV, Sweeley CC, Jamieson GA.
In this seminal publication Tao and colleagues identified lactosylceramide (CD17) as a major glycosphingolipid in platelets. They conclude that “the presence of a relatively high proportion of ceramide in platelets may be a unique characteristic of this cellular fraction of blood.”
