(A) Basal mRNA expression of chemokines CX3CL1, CCL2, CCL7, CXCL12, CXCL5 and CCL5 in mesenteric tissue (n=6 mice). (B) Chemokine receptor mRNA expression in resident peritoneal cells (n=4-6 mice). Levels of mRNA for each sample are normalized to corresponding mRNA levels of housekeeping gene for small 18S and calculated as fold expression relative to the mean value in males, except CX3CR1 (relative to female). All values are expressed as mean ± sem. *P<0.05 and **P<0.01 by Student’s t-test. ND denotes chemokine expression that was not detected within 35 PCR cycles.
