Chemerin Does Not Inhibit Inflammatory Responses Figure 2. Mouse peritoneal macrophages express a functional ChemR23 receptor. (A) Peritoneal macrophages from WT or ChemR232/2 mice, collected following i.p. Bio-Gel injection, were stimulated for 15 h by 100 ng/ml LPS or left unstimulated. Cells were harvested, and expression of ChemR23 was determined by quantitative RT-PCR. Data are expressed as mean 6 SEM for 3 independent experiments performed in duplicate.
