title: Calcium signalling: sphingosine kinase versus phospholipase C?
abstract: A recent study shows that sphingosine kinase and its lipid product have an essential signalling function; they act in the mobilization of calcium ions in antigen-stimulated mast cells. This finding may have relevance to signalling in other cells of the immune system.
