Figure 5

Bar graphs demonstrate the effect of 3-isobutyl-1-methylxanthine (IBMX, 1 mmol/L; broad spectrum phosphodiesterase inhibitor) and 1,3-dipropyl-8-p-sulfophenylxanthine (DPSPX, 1 mmol/L; ecto-phosphodiesterase inhibitor) on the conversion of extracellular 2′,3′-cAMP to 2′-AMP and 3′-AMP by CNPase +/+ or CNPase -/- oligodendrocytes (A - D) and neurons (E -H). “a” indicates significance difference versus No Inhibitor group (same group as in Figure 2). Significance is defined as P<0.05. Values represent means ± SEM for 6 experiments.
