Sialyl LewisX (sLeX), also known as cluster of differentiation 15s (CD15s) or stage-specific embryonic antigen 1 (SSEA-1), is a tetrasaccharide carbohydrate which is usually attached to O-glycans on the surface of cells. It is known to play a vital role in cell-to-cell recognition processes. It is also the means by which an egg attracts sperm; first, to stick to it, then bond with it and eventually form a zygote. The discovery of the essential role that this tetrasaccharide plays in the fertilization process was reported in August 2011.

The discovery of the essential role that this tetrasaccharide plays in the fertilization process was reported in August 2011. Sialyl Lewis X is also one of the most important blood group antigens and is displayed on the terminus of glycolipids that are present on the cell surface. The sialyl Lewis X determinant, E-selectin ligand carbohydrate structure, is constitutively expressed on granulocytes and monocytes and mediates inflammatory extravasation of these cells. Resting T- and B-lymphocytes lack its expression and are induced to strongly express sialyl Lewis X upon activation. The sialyl Lewis X determinant is expressed preferentially on activated Th1 cells but not on Th2 cells. (en)
  • Il Sialil-LewisX, (o sialil LeX, o sLeX, o sLe*), è un tetrasaccaride tipicamente legato alla superficie cellulare, mediante legami O-glicosidici. SLeX svolge un ruolo nel riconoscimento cellula-cellula, è inoltre il mediatore dell'attrazione degli spermatozoi da parte della cellula uovo nelle fasi del legame, fusione e formazione dello zigote. La prima segnalazione di questa essenziale funzione svolta dal tetrasaccaride nel processo della fecondazione si è avuta nel 2011 Sialil-Lewis X è anche un importante antigene per la determinazione del gruppo sanguigno e viene rilevato all'estremità di glicolipidi presenti sulla superficie cellulare. Il determinante del sialil-Lewis X è la struttura carboidratica che lega l'E-selectina ed è costitutivamente espresso sui granulociti e sui monociti. Nella risposta infiammatoria media la fase di rotolamento (rolling) che precede la fuoriuscita di queste cellule dai vasi. I linfociti T e B a riposo non esprimono la molecola fino al momento dell'attivazione. Il sialil-Lewis X è espresso preferenzialmente su cellule Th1 attivate, ma non su cellule Th2. (it)
