Immortalized human choroid plexus endothelial cells enable an advanced endothelial-epithelial two-cell type in vitro model of the choroid plexus

ABSTRACT: We describe here the generation and characterization of immortalized HCPEnC (iHCPEnC) by ectopic expression of hTERT in primary cells using a lentiviral vector system without additional support by a viral oncogene. RNA sequencing (RNA-seq) analysis revealed that iHCPEnC retained an RNA expression profile very similar to the primary HCPEnC and different from that of other endothelial cell types as Human Brain Microvascular Endothelial Cells (HBMEC) and Human Umbilical Vein Endothelial Cells (HUVEC).

Immortalized human choroid plexus endothelial cells enable an advanced endothelial-epithelial two-cell type <i>in vitro</i> model of the choroid plexus.

Project description:The choroid plexus (CP) is a highly vascularized structure containing endothelial and epithelial cells located in the ventricular system of the central nervous system (CNS). The role of the fenestrated CP endothelium is under-researched and requires the generation of an immortalized CP endothelial cell line with preserved features. Transduction of primary human CP endothelial cells (HCPEnC) with the human telomerase reverse transcriptase (hTERT) resulted in immortalized HCPEnC (iHCPEnC), which grew as monolayer with contact inhibition, formed capillary-like tubes in Matrigel, and showed no colony growth in soft agar. iHCPEnC expressed pan-endothelial markers and presented characteristic plasmalemma vesicle-associated protein-containing structures. Cultivation of iHCPEnC and human epithelial CP papilloma (HIBCPP) cells on opposite sides of cell culture filter inserts generated an in vitro model with a consistently enhanced barrier function specifically by iHCPEnC. Overall, iHCPEnC present a tool that will contribute to the understanding of CP organ functions, especially endothelial-epithelial interplay.

Effects of Smoldering Eucalyptus Wood Smoke Extract on Primary Human Brain Microvascular Endothelial Cells (HBMEC) and Immortalized Human Cerebral Microvascular Endothelial Cell Line (hCMEC/D3)

Project description:Increase in frequency and size of wildfire raises a significant public health concern due to rapid climate change. Epidemiological studies have shown that wildfire smoke exposure can increase the risk of neurological disorders. Our study aims to understand how wildfire smoke particles affect brain endothelial cells using both primary human brain microvascular endothelial cells (HBMEC) and an immortalized human cerebral microvascular endothelial cell line (hCMEC/D3). HBMEC and hCMEC/D3 were exposed to different levels of smoldering eucalyptus smoke particles (10, 30, 50 ug/mL) for 24 hr. Supernatants were collected for LDH and ELISA array, cell lysates were collected for RNAseq, and cells were fixed and stained for tight junction marker (Zonula Occludens-1, ZO-1) via ICC. Our study found that treatment to smoldering eucalyptus particles can increase inflammatory cytokine production dose-dependently in HBMECs and hCMEC/D3. Moreover, RNAseq analyses resulted in dose-dependent changes in HBMEC and hCMEC/D3 from wood smoke treatment that could be mediated via AhR and Nrf2 pathways.

Marinobufagenin regulates gene expression in human brain microvascular endothelial cells in vitro.

Project description:To understand the mechanism by which MBG increases permeability of human brain microvascular endothelial cell (HBMEC) monolayers, the primary cultures were treated with 10nM MBG for 12 h. RNA was isolated and analysed for gene expression on Agilent one color microarrays. Triplicate wells of HBMEC were treated with 10 nM MBG in DMSO or with just the drug vehicle for 12 h. RNA was isolated from each well and used to reverse transcribe and generate Cy3-labelled cRNA. Microarrays were hybridized, washed and scanned. Data were normalized and assessed for differential gene expression between MBG treated and control HBMEC.

RNA expression profiling in primary and immortalized human mesothelial cells, and in human vein and microvascular endothelial cells

Project description:Mesothelial cells, which interact with endothelial cells, are widely used in research including cancer and drug development, have not been comprehensively profiled. We therefore performed RNA sequencing of polarized, primary peritoneal (HPMC) and immortalized pleural mesothelial cells (MeT-5A), and compared it to endothelial cells from umbilical vein (HUVEC) and cardiac capillaries (HCMEC).

Comparison of primary vs immortalized HUVEC

Project description:Fundamental research and drug development for personalized medicine necessitates cell cultures from defined genetic backgrounds. However, providing sufficient numbers of authentic cells from individuals poses a challenge. Here, we present a new strategy for rapid cell expansion that overcomes current limitations. Using a small gene library, we expanded primary cells from different tissues, donors and species. Cell type specific regimens that allow the reproducible creation of cell lines were identified. In depth characterization of a series of endothelial and hepatocytic cell lines confirmed phenotypic stability and functionality. Applying this technology enables rapid, efficient and reliable production of unlimited numbers of personalized cells. As such, these cell systems support mechanistic studies, epidemiological research and tailored drug development. In these experiments primary HUVEC were compared to immortalized HUVEC with respect to their global gene expression pattern.

Plasmodium falciparum and TNF-a Differentially Regulate Inflammatory and Barrier Integrity Pathways in Human Brain Endothelial Cells

Project description:Cerebral malaria is a severe complication of Plasmodium falciparum infection characterized by the loss of blood-brain barrier (BBB) integrity, which is associated with brain swelling and mortality in patients. P. falciparum-infected red blood cells and in!ammatory cytokines, like tumor necrosis factor alpha (TNF-a), have been implicated in the development of cerebral malaria, but it is still unclear how they contribute to the loss of BBB integrity. Here, a combination of transcriptomic analysis and cellular assays detecting changes in barrier integrity and endothelial activation were used to distinguish between the effects of P. falciparum and TNF-a on a human brain microvascular endothelial cell (HBMEC) line and in primary human brain microvascular endothelial cells. We observed that while TNF-a induced high levels of endothelial activation, it only caused a small increase in HBMEC permeability. Conversely, P. falciparum-infected red blood cells (iRBCLs) led to a strong increase in HBMEC permeability that was not mediated by cell death. Distinct transcriptomic pro"les of TNF-a and P. falciparum in HBMECs con"rm the differential effects of these stimuli, with the parasite preferentially inducing an endoplasmic reticulum stress response. Our results establish that there are fundamental differences in the responses induced by TNF-a and P. falciparum on brain endothelial cells and suggest that parasite-induced signaling is a major component driving the disruption of the BBB during cerebral malaria, proposing a potential target for much needed therapeutics.
