Autophagy, 2007•Taylor & FrancisSphingolipids are major constituents of biological membrane and some of them behave as
second messengers involved in the cell fate decision. Ceramide and sphingosine 1-
phosphate (S1P) constitute a rheostat system in which ceramide promotes cell death and
S1P increases cell survival. We have shown that both sphingolipids are able to trigger
autophagy with opposing outcomes on cell survival. Here we discuss and speculate on the
diverging functions of the autophagic pathways induced by ceramide and S1P, respectively …
