Lilach Moyal, PhD, Tel Aviv University, Tel Aviv, Israel, explains how inhibition of the CXCR4/CXCL12 axis leads to tumor cell death. CXCR4 antagonists bind to the CXCR4 receptor and prevent CXCL12 from inducing signaling cascades resulting in chemotaxis and survival of malignant cells, which eventually results in their apoptosis. This interview took place at the EORTC Cutaneous Lymphoma Group 20-21 meeting in Marseille.
