Figure 4.

Gp120 exposure did not induce cell proliferation, necrosis or TUNEL within 24 hours of exposure. Gp120 exposure time series data for Ki-67 (a), LDH (b) showing no significant differences at timepoints between 0 and 72 hours for proliferation or necrosis. TUNEL (c) data suggest a small increase in apoptosis over baseline at 72 hours after gp120 exposure in comparison to all timepoints except 2 hours. Error bars: +/- 1 standard error.
