Abstract:
:Natural killer (NK) cells perform multiple biological functions including tumor cell lysis and eradicating virally infected cells. Here, we report for the first time that D-galactosyl-beta1-1' sphingosine and D-glucosyl-beta1- 1' sphingosine damage human NK cells. We show that these cells express T-cell-associated gene-8, the receptor for glycosphingolipids. D-galactosyl-beta1-1' sphingosine and D-glucosyl-beta1-1' sphingosine induce the in vitro chemotaxis of human NK cells. Both D-galactosyl-beta1-1' sphingosine and D-glucosyl-beta1-1' sphingosine inhibit the cytotoxicity and IFN-gamma secretion by these cells. Further analysis shows that the glycosphingolipids D-galactosyl-beta1-1' sphingosine and D-glucosyl-beta1-1' sphingosine but not any other lipid examined, which include D-lactosyl-beta1-1' sphingosine, sphingosine 1-phosphate, sphingosine, lysophosphatidic acid, and phosphatidic acid, induce the apoptosis, globoid-like formation, and multinucleation in human NK cells. These results may have important implications on diseases where glycosphingolipids accumulate.
