Copyright information:Taken from "The effect of aging and caloric restriction on murine CD8+ T cell chemokine receptor gene expression"http://www.immunityageing.com/content/4/1/8Immunity & ageing : I & A 2007;4():8-8.Published online 14 Nov 2007PMCID:PMC2200663. Autoradiographs of representative ribonuclease protection assay (RPA) showing the effect of aging and anti-CD3/anti-CD28 monoclonal antibody (mAb) stimulation on murine CD8+ T cell CCR1–5 (A) and CXCR2, 4 and 5 (B) gene expression. Lane 1 in Figure 2A and Lane 2 in Figure 2B = Young (3–4 months) unstimulated cells; Lane 2 in Figure 2A and Lane 3 in Figure 2B = Old (18–20 months) unstimulated cells; Lane 3 in Figure 2A and Lane 4 in Figure 2B = Young cells after 72 hours of anti-CD3/anti-CD28 mAb stimulation; Lane 4 in Figure 2A and Lane 5 in Figure 2B = Old cells after 72 hours of anti-CD3/anti-CD28 mAb stimulation; Lane 5 in Figure 2A and Lane 1 in Figure 2B = unprotected probe set. Composite histogram (C) of 3 RPAs using pooled RNA from a total of 15 animals in each age group is shown. Gel loading is corrected with L32 expression.
