Figure 6From: Interleukin-1β and anaphylatoxins exert a synergistic effect on NGF expression by astrocytesProduction of NGF by T98G cells analyzed by ELISA after incubation with C3a, C5a, MAP-C3a, MAP-C5a (10-8M) for 48 h. The concentration of NGF was measured in the supernatants and was expressed as pg/ml per 106 cells. Bars represent the mean ± SEM for three independent experiments.Back to article page
