T-cell acute lymphoblastic leukaemia (T-ALL) patients are at an increased risk of central nervous system (CNS) relapse, and yet, despite its clinical importance, little is known about the mechanism of leukaemic cell infiltration of the CNS. Here, using T-ALL animal modelling and gene-expression profiling, the chemokine receptor CCR7 is shown to be the essential adhesion signal required for the targeting of leukaemic T cells into the CNS.
