Inhibition of ApoE4-induced cell death by PTX or ApoE3

	Cell mortality (% dead cells of total cells)
ApoE3	10.2  ± 5.1
ApoE4	74.7  ± 2.2
ApoE4 + PTX	25.1  ± 6.6*
ApoE4 + inactivated PTX	73.5  ± 11.61-160
ApoE4 + ApoE3	30.4  ± 10.0*

F11 cells were treated with 30 μg/ml ApoE4 with or without several reagents for 72 hr. Cell mortality was measured by Trypan blue exclusion. PTX was used at 1 μg/ml; ApoE3, at 30 μg/ml. The values indicate means ± SE of four independent experiments.

^*p < 0.01 and

F1-160: not significant versus ApoE4 effect.
