Chondroitin sulfate proteoglycans prevent immune cell phenotypic conversion and inflammation resolution via TLR4 in rodent models of spinal cord injury

Inflammation resolution failure is a pathological hallmark of spinal cord injury. Here, the authors show in rodents that chondroitin sulfate proteoglycans contribute to failed resolution by preventing immune cells at the injury core from converting to a pro-resolution phenotype, and this is mediated by TLR4.
