SDF-1β mRNA levels in the mouse brain after peripheral LPS administration

	3 hr saline	0.5 hr LPS	1 hr LPS	3 hr LPS	6 hr LPS	24 hr LPS
SDF-1β mRNA	381 ± 36	289 ± 26	275 ± 44	133 ± 82* (34%)	138 ± 92* (36%)	203 ± 57*(53%)

SDF-1β mRNA levels of whole-brain sections expressed in nanoCuries per gram ± SD (mean values of four animals in the group 3 hr after saline injection and three animals per LPS-treated group). Bold values express measurements as percentage of the group 3 hr after saline injection. *p < 0.05 versus the saline-injected group. One-way ANOVA followed by Dunnett's multiple comparison test.
