IL6 and Alzheimer disease: Both the healthy control and AD-derived astrocytes basally secreted small amounts of IL-6 (26.9 pg/mL ± 29.4 SD and 74.1 pg/mL ± 83.5 SD, respectively) (Fig. 6A) and showed increased secretion of IL-6 from basal upon stimulation with 10 μg/mL LPS (454.5 pg/mL ± 589.3 SD and 398.3 pg/mL ± 387.7 SD, respectively) and 50 μg/mL LPS (460.6 pg/mL ± 552.3 SD and 478.0 pg/mL ± 447.4 SD, respectively), albeit no significant differences being found between healthy controls and AD-derived astrocytes (Fig. 6A).
