描述
Lewis X trisaccharide is a common oligosaccharide involved in the terminal glycosylation of oligosaccharide chains of glycoconjugates and as such play a major role in the antigenic properties of cell surfaces and in the changing carbohydrates profiles that occur on cell maturation and in malignancy. Lewis X present in human milk can bind to DC-specific ICAM3-grabbing non-integrin and thereby prevent the capture and subsequent transfer of HIV-1 to CD4+ T lymphocytes. The presence of such a DC-specific ICAM3-grabbing non-integrin-binding molecule in human milk may both influence antigenic presentation and interfere with pathogen transfer in breastfed infants. Lewis X is a promising urine marker for bladder cancer surveillance in urothelial cell carcinoma patients.
