Dissecting trafficking and signaling of atypical chemokine receptors.

ABSTRACT

Atypical chemokine receptors are a distinct subset of chemokine receptors able to modulate immune responses by acting as chemokine decoy/scavengers or transporters. Intracellular trafficking properties sustained by Gαi-independent signaling have emerged as a major determinant of their biological properties, which support continuous uptake, transport, and/or concentration, of the ligands. Here, we are providing methods to study both trafficking and signaling of this class of chemokine receptors focusing on the atypical chemokine receptor D6 that degrades inflammatory CC chemokines.
