TABLE 1.

Amounts of TNF-α and IL-1β secreted from microglial cells cocultured with A. culbertsoni trophozoites or lysate for 6 h

Culture conditions	Amt (pg/ml) secreted
	TNF-α	IL-1β
Microglial cells:
In EMEM medium	32.5 ± 2.97a	131.4 ± 43.91
With PBS	40.5 ± 4.38	150.4 ± 13.44
Microglial cells with:
A. culbertsoni trophozoites (1:1)b	114.3 ± 7.99	129.6 ± 19.30
1 mg of lysate per ml	95.6 ± 0.71	18.2 ± 6.05
0.5 mg of lysate per ml	119.9 ± 1.41	20.6 ± 1.69

^aValues are means ± standard deviations. 

^bThe ratio is the number of microglial cells to the number of trophozoites.
