Astrocytes from Cx3cr1-/-mice do not shown any alterations in the transcription factor NRF2 signalling. Primary cultures of astrocytes from Cx3cr1+/+ and Cx3cr1−/− mice were incubated with SFN (15 μM, 6 h). Quantitative real-time PCR determination of messenger RNA levels of NRF2-regulated genes coding Nfe2l2, Nqo1, Gclc and Osgin1, respectively, normalized by Actb (β-Actin) messenger RNA levels. Two-way ANOVA followed by Bonferroni post-test was used to assess significant differences among groups. Asterisks denote significant differences ***p < 0.001 respect to the basal Cx3cr1+/+ group.
