Type I (H1, Lewis a, Lewis b, and sialyl Lewis a) and type II (H2, Lewis x, Lewis y, and sialyl Lewis x) Lewis antigens are terminal fucosylated carbohydrate motifs decorating cell surface glycoproteins or glycolipids.In the case of glycoproteins, N- and O-linked glycans containing Lewis … WebThe sialyl-Lewis A (sLeA) glycan forms the basis of the CA19-9 assay and is the current best biomarker for pancreatic cancer, but because it is not elevated in ∼25% of pancreatic cancers, it is not useful for early diagnosis. We hypothesized that sLeA-low tumors secrete glycans that are related to sLeA but not detectable by CA19-9 antibodies.

WebJun 22, 2005 · The expression of sulfated sialyl Lewis X glycans was reported to increase in endothelium of bronchial asthma, but not that of other chronic inflammatory diseases (Toppila et al., 2000). Adhesion molecules expressed on eosinophils such as Siglec-F might mediate eosinophil adhesion and infiltration into the airway. WebJun 8, 2010 · For example, sialyl-Lewis x (sLe x) antigens are the ligands for selectins and are involved in the recruitment of leukocytes to lymphoid tissues and inflammation sites . Glycan structures depend on the cell type, developmental stage and cell differentiation, and are modified in many pathologic states including cancers.
