LPS-induced MIP-2 production is inhibited by curcumin. Confluent astrocytes were cultured in medium alone or were stimulated with LPS (5 μg/ml) in the presence (LPS + Curcumin) or absence (LPS) of curcumin (10^-5 M). The supernatants were collected after 16 hours and MIP-2 protein (in picograms/ml) was measured by ELISA. Data are the mean ± standard deviation of 4 experiments. Mean MIP-2 production in the medium and LPS + curcumin groups differ significantly from that in the LPS group (p < 0.001 by Student's t test). Mean MIP-2 production does not differ significantly between the medium and LPS + curcumin groups (p > 0.2 by Student's t test).
