Our current study revealed that the levels of the chemokines CCL3 and CCL4 in the spleens and peritoneal exudates of mice with peritonitis were significantly reduced in the ATG group compared to the control group, suggesting that inflammation was alleviated, and this alleviation of inflammation also caused the significant reductions in the numbers of neutrophils and macrophages. Here, CCL4 is linked to peritonitis.
