UNLABELLED The blood-brain barrier (BBB) limits entry of blood-derived products, pathogens, and cells into the brain that is essential for normal neuronal functioning and information processing. Post-mortem tissue analysis indicates BBB damage in Alzheimer's disease (AD). The timing of BBB breakdown remains, however, elusive. Using an advanced dynamic… (More)
Structural and functional brain connectivity, synaptic activity, and information processing require highly coordinated signal transduction between different cell types within the neurovascular unit and intact blood-brain barrier (BBB) functions. Here, we examine the mechanisms regulating the formation and maintenance of the BBB and functions of… (More)
Two recent papers in Nature, Ben-Zvi et al. (2014) and Nguyen et al. (2014), report a surprising dual role for the blood-brain barrier transporter MFSD2A in both establishing BBB integrity and in uptake of the fatty acid DHA.
