Quantitative analysis of relative cytokine expression in rats treated with 1 mg/kg gp91ds-tat or scrambled peptide 15 minutes following moderate contusion SCI. Two groups of cytokines were found: (A) high-expressing proteins, with more than 15pg/ml concentrations, and (B) low-expressing proteins, with expression of less than 5pg/ml. Significant reductions in several cytokines were observed, particularly in the low expression group (B); overall 13 cytokines were found reduced with gp91ds-tat treatment. N = 4/group, *p < 0.05.
