Leucocyte expression of the chemokine scavenger D6

Selective sequestration of inflammatory chemokines is critical for the successful resolution of inflammatory responses in vivo. D6 is an atypical chemokine receptor that scavenges inflammatory chemokines and is pivotal in resolving models of chemokine-driven cutaneous inflammation. We provide evidence that expression of D6 is not limited to the lymphatic endothelium at sites of inflammation as previously believed. Instead we postulate that D6 expression in leucocytes may have a significant impact upon chemokine bioavailability during the resolution phase of inflammation. D6 expressed on the lymphatic endothelia may instead have complementary roles in preventing inappropriate leucocyte migration to the lymph node by keeping the endothelium free from inflammatory chemokines.
