Gene expression of IL-1β, IL-6, TNF-α, CD11B, MMP-9 and GFAP after 2 h of tMCAO 24 h post reperfusion. Gene expression of IL-1β, IL-6, TNF-α, CD11B, MMP-9 and GFAP of 3 consecutive coronal sections of TTC-stained hemispheres. The contralateral non-infarcted hemispheres of the vehicle-treated group acted as internal controls. Values of these hemispheres were therefore set to 100%. All other values (infarcted hemisphere vehicle-treated group, infarcted and non-infarcted hemisphere of the Solulin cohort) were expressed as percentages of the latter. RT-PCR values were normalized to the housekeeping genes HPRT and cyclophilin A. All mRNA levels are given as means ± SEM.
