FIG. 2.

Th1/Th2 cytokine mRNA expression at time zero, 3 h, and 24 h after pneumococcal CCS stimulation (1 μg/ml). (a) PCR product for each cytokine on a 1.5% agarose gel. (b) Expression of mRNA of each cytokine relative to GAPDH expression. The data are means and standard deviations of six experiments. One asterisk indicates that the P value is <0.05 compared to the data for time zero (before stimulation), and two asterisks indicate that the P value is <0.01 compared to the data for time zero (before stimulation).
