Figure Lengend Snippet: CCL5 regulates macrophage polarization mainly through CCR1- and CCR5-related MAPK/NF-κB pathways. a Mouse peritoneal macrophages (PMφ) were stimulated with 100 ng/ml rmCCL5 for 0–60 min, and the signaling activation of the MAPK and NF-κB pathways was detected by western blot analysis. b PMφ were pretreated with a CCR1/3/5 antagonist separately for 1 h and then stimulated with 100 ng/ml rmCCL5 for 30 min. The signaling activation of the MAPK and NF-κB pathways was detected by western blot analysis. c PMφ were pretreated with a CCR1/3/5 antagonist separately for 1 h and then stimulated with 100 ng/ml rmCCL5 for 6 h. qPCR analysis of M1 marker and M2 marker expression was performed (n = 4). d, e Raw 264.7 cells were pretreated with control, CCR1, or CCR5 siRNA separately for 48 h. d Western blot analysis detected the knockdown of CCR1 and CCR5. siRNA-treated cells were stimulated with 100 ng/ml rmCCL5 for 30 min, and the signaling activation of the MAPK and NF-κB pathways was detected by western blot analysis. e siRNA-treated cells were stimulated with 100 ng/ml rmCCL5 for 6 h, and qPCR analysis of M1 marker and M2 marker expression was performed (n = 4). The data are shown as means ± SEM, *P < 0.05. **P < 0.01, ***P < 0.001
Article Snippet: To evaluate the therapeutic potential of CCL5 inhibition, a CCL5-neutralizing antibody (anti-CCL5, AF478, R&D, USA); control IgG (AB-108-C, R&D, USA); or a CCL5 receptor antagonist (Met-CCL5, 335-RM/CF, R&D, USA) were reconstituted in sterile PBS and administered to WT mice (10 μg/injection, i.p) 6 and 24 h after APAP overdose.
