PIOL supernatant counteracts in vitro antiproliferative effect of CpG-ODNs on A20.IIA malignant B cells. 10⁴ cells were stimulated for 72 hours with various concentrations of CpG or control ODNs in concentrations ranging from 0.003 to 60 μg/mL or with medium alone and with the presence of supernatant from (A) PBS 1X injected eyes (PIE), (B) SCL, (C) PCL, or (D) PIOL. The incorporation of the [³H] thymidine was measured by a scintillation counter. *P < 0.05; **P < 0.01. The data shown are representative results from 1 of 3 experiments.
