G-protein-coupled receptors in control of natural killer cell migration.

Author information

Université de Lyon, France.


Natural killer (NK) cells are highly motile cells that patrol lymphoid and non-lymphoid organs, and are poised to react to infectious or other inflammatory situations. Several NK cell subsets equipped with different sets of chemotactic G-protein-coupled receptors, and which display distinct distribution across lymphoid and non-lymphoid organs, have been described. These receptors detect various guidance cues including sphingosine-1-phosphate and chemokines that orchestrate NK cell trafficking. Here, we highlight recent advances regarding the receptors involved in NK cell migration, with a focus on bone marrow egress, entry into activated lymph nodes, extravasation into inflamed tissues, and motility within lymph nodes or tumors. Understanding NK cell migration could provide a rational basis for the design of novel therapies in various clinical conditions.
