Rotenone inhibits secretion of TNF-α from astrocytes. Except group blank, the cells of all groups were treated with 10 μg/ml LPS for 48 h along with respective treatments. The cells of group blank were cultured for 48 h without any treatment. Control LPS alone, rotenone 20 nM, apyrase 5 U/ml, BzATP 100 μM. *P_{rotenone vs. control} < 0.05. ^†P_{rotenone+BBG vs. rotenone} < 0.05. ^‡P_{BzATP vs. control} < 0.01. ^§P_{rotenone+BzATP vs. rotenone} < 0.05
