Time course experiments show different kinetics of cytokine secretion due to IL-1β stimulation. (A) Secretion of pro inflammatory cytokines was significantly increased in the supernatant of IL-1β stimulated astrocytes by ELISA experiments. Data are shown as mean ± SEM of three independent experiments in duplicate assay. ANOVA Repeated Measures, followed by Tukey’s pairwise comparison, p < 0.05 versus control group. (B) Representative immunoblots of IL-6, GM-CSF, and CCL5 expression in the supernatans of astrocyte cultures. In the cytosol of astrocyte cultures GFAP expression also shows gradual time-dependent enhancement.
