Groups of wild type C57BL/6, B6.CCR5−/− and B6.CD8−/−CCR5−/− mice (n = 4) received renal allografts from A/J donors and a group of wild type C57BL/6 mice received isografts (n = 4). Grafts were harvested on days 3, 7, and 14 post-transplant and at the time of the rejection. On the indicated day post-transplant, kidneys were harvested and whole cell RNA was prepared and analyzed by qRT/PCR for expression of the indicated neutrophil chemoattractant CXCL1 and CXCL2, T cell chemoattractant RANTES, and inflammatory mediator genes. Data indicate the mean expression levels for each group on the indicated day ± SEM. All significant differences are indicated by *P<0.05.
