Amino acid transporters expressed in isolated choroid plexuses. aTtr, Gfap, Cd31 and Syp mRNAs in isolated choroid plexuses (closed bars) and cerebrums (open bars) in 3 independent experiments. Data are indicated (mean ± SEM, n = 10). Statistical analysis was performed by unpaired t-test and statistically significant changes are indicated as ***p < 0.001, **p < 0.01. b Presence of 14 selected Slc genes, which products involved in AA transport, was tested on mRNA level in 3 independent experiments; data presented as mean ± SEM, n = 10. Statistical analysis was performed by ANOVA followed by Dunnet’s post-test and statistically significant differences relative to Lat2 (Slc7a8) mRNA are indicated as ***p < 0.001, **p < 0.01
