AbstractThe blood–brain barrier (BBB) has a vital role in maintaining the homeostasis of the central nervous system (CNS). Changes in the structure and function of BBB can accelerate Alzheimer’s disease (AD) development. β-Amyloid (Aβ) deposition is the major pathological event of AD. We elucidated the function and possible molecular mechanisms of the effect of pseudogene ACTBP2 on the permeability of BBB in Aβ1–42 microenvironment. BBB model treated with Aβ1–42 for 48 h were used to simulate Aβ-mediated BBB dysfunction in AD. We proved that pseudogene ACTBP2, RNA-binding protein KHDRBS2, and transcription factor HEY2 are highly expressed in ECs that were obtained in a BBB model in vitro in Aβ1–42 microenvironment. In Aβ1–42-incubated ECs, ACTBP2 recruits methyltransferases KMT2D and WDR5, binds to KHDRBS2 promoter, and promotes KHDRBS2 transcription. The interaction of KHDRBS2 with the 3′UTR of HEY2 mRNA increases the stability of HEY2 and promotes its expression. HEY2 increases BBB permeability in Aβ1–42 microenvironment by transcriptionally inhibiting the expression of ZO-1, occludin, and claudin-5. We confirmed that knocking down of Khdrbs2 or Hey2 increased the expression levels of ZO-1, occludin, and claudin-5 in APP/PS1 mice brain microvessels. ACTBP2/KHDRBS2/HEY2 axis has a crucial role in the regulation of BBB permeability in Aβ1–42 microenvironment, which may provide a novel target for the therapy of AD.

The vertebrate vasculature displays high organotypic specialization, with the structure and function of blood vessels catering to the specific needs of each tissue. A unique feature of the central nervous system (CNS) vasculature is the blood-brain barrier (BBB). The BBB regulates substance influx and efflux to maintain a homeostatic environment for proper brain function. Here, we review the development and cell biology of the BBB, focusing on the cellular and molecular regulation of barrier formation and the maintenance of the BBB through adulthood. We summarize unique features of CNS endothelial cells and highlight recent progress in and general principles of barrier regulation. Finally, we illustrate why a mechanistic understanding of the development and maintenance of the BBB could provide novel therapeutic opportunities for CNS drug delivery.

AbstractGlia play key roles in regulating multiple aspects of neuronal development and function from invertebrates to humans. We recently found microdomain Ca2+ signaling in Drosophila cortex glia and astrocytes regulate extracellular K+ buffering and neurotransmitter uptake, respectively. Here we identify a role for ER store-operated Ca2+ entry (SOCE) in perineurial glia (PG), a distinct population that contributes to the blood-brain barrier (BBB). PG show a diverse range of Ca2+ oscillatory activity that varies based on their locale within the brain. Unlike cortex glia and astrocytes, PG Ca2+ oscillations do not require extracellular Ca2+ and are blocked by inhibition of SOCE or gap junctions. Disruption of these components triggers heat shock and mechanical-induced seizure-like episodes without effecting PG morphology or large molecule BBB permeability. These findings indicate SOCE-mediated Ca2+ oscillations in PG increase the susceptibility of seizure-like episodes in Drosophila, providing an additional link between glial Ca2+ signaling and neuronal activity.
