Blockade of the CXC chemokine receptor 3 (CXCR3) attenuates inflammation and improves survival in a murine model of near lethal polymicrobial sepsis. However, given the multitude of cellular responses and inflammatory mediators that orchestrate sepsis syndrome, more detailed investigations will be required before a complete understanding of the mechanism(s) of CXCR3 blockade and its therapeutic potential are revealed.
