The lymph node periphery is an important site for many immune functions, from pathogen containment to T helper differentiation, yet the cues that position cells in this region are largely undefined. Here, using a sphingosine 1-phosphate (S1P) reporter, we found that cells sensed higher concentrations of S1P in the medullary cords than in the T zone, and the S1P transporter SPNS2 on lymphatic endothelial cells generated this gradient. Natural killer (NK) cells are located at the periphery of the lymph node, predominantly in the medulla, and we found that expression of SPNS2, S1P receptor 5 on NK cells, and CXCR4 were all required for NK cell localization during homeostasis and rapid interferon-? production by NK cells after challenge. Our findings elucidate the spatial cues for NK cell organization, and reveal a novel role of S1P in positioning cells within the medulla.
