eLife Assessment
This important study provides solid in-vivo evidence that CCR4 regulates the early inflammatory response during atherosclerotic plaque formation. The authors propose that altered T-cell response plays a role in this process, shedding light on mechanisms that may be of interest to medical biologists, biochemists, cell biologists, and immunologists. Further in vivo validation, mechanistic studies, and discussion of results in vitro suggested would be helpful to cement the significance and implications of these findings.
