ABCC1 and Alzheimer disease: Interestingly, we have not observed changes in protein expression of other investigated SLC transporters as well as ABC transporters in the NVU cells of 5xFAD mice, while altered expression of FATP1, Abcg2, and Abcc1 in the isolated brain microvessels of TgF344-AD rats compared to WT controls was reported in our previous study [28].
