Fig. 6From: Intraventricular infusion of quinolinic acid impairs spatial learning and memory in young rats: a novel mechanism of lead-induced neurotoxicityExpression of CREB (a), pCREB (b), synaptophysin (c), and PSD-45 (d) in the control and QA-infused rats at PND45 and PND60. All protein expressions were normalized to actin signal. Representative blots are shown above each graph. Data presented as mean ± SD (n = 4); mean data were compared with Student’s t test. Note significantly decreased expression of PSD-45 at PND45 (*p < 0.05)Back to article page
