CCL5 is an important chemokine for modulation of inflammatory responses, but how CCL5 expression is regulated is still unclear. Here the authors show that the CCL5 locus contains two enhancers, with the proximal enhancer being responsible for homeostatic expression and the distal enhancer enforcing inducibility, while both enhancers are modulated by RUNX3.
