Project description:The aim of this study is to understand how NMV can affect the vascular integrity of the blood-brain barrier using a cell line- hCMEC/D3. Recent studies have reported that NMV can affect other endothelial barriers in the body contributing to inflammation and pathogenesis of diseases such as atherosclerosis. The transcriptomic profile of NMV-treated hCMEC/D3 cells was compared to that of cells without treatment to understand whether functional groupings and pathways are differentially expressed, which can contribute to changes in blood-brain barrier.

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.

Project description:Functional and structural dysfunction of the blood brain barrier (BBB) leads to severe alterations in brain physiology and is believed to trigger neurodegeneration. To investigate the molecular mechanisms driving the BBB dysfunction, very few human BBB cell culture models are available; of which, the human microvascular endothelial cell line (hCMEC/D3) is the most widely used. Thus far, array-based approaches or targeted seqeuncing based approaches have been employed to characterize the gene expression of the hCMEC/D3 model. However,The goal of this study is to perform deep transcriptomic sequencing of the BBB cell line and obtain features like gene expression, expressed single nucleotide variants, alternate splice forms, circular RNAs, long non-coding RNAs and micro RNAs. We have developed blood brain barriers transcriptomics landscape using RNA sequencing and micro RNA seqeuncing data obtained from replicates of hCMEC/D3 BBB cell line.

Project description:Background: Radiation therapy is the standard of care for central nervous system tumours. Despite the success of radiation therapy in reducing tumour mass, irradiation (IR)-induced vasculopathies and neuroinflammation contribute to late-delayed complications, neurodegeneration, andpremature ageing in long-term cancer survivors. Mesenchymal stromal cells (MSCs) are adult stem cells that facilitate tissue integrity, homeostasis, and repair. Here, we investigated the potential of the iPSC-derived MSC(iMSC) secretome in immunomodulation and vasculature repair in response to radiation injury utilizing human cell lines. Methods: We generated iPSC-derived iMSC lines and evaluated the potential of their conditioned media (iMSC CM) to treat IR-induced injuries in human monocytes (THP1) and brain vascular endothelial cells (hCMEC/D3). We further assessed factors in the iMSC secretome, their modulation, and the molecular pathways they elicit. Results: Increasing doses of IR disturbed endothelial tube and spheroid formation in hCMEC/D3. When IR-injured hCMEC/D3 (IR ≤ 5 Gy) were treated with iMSC CM, endothelial cell viability, adherence, spheroid compactness, and proangiogenic sprout formation were significantly ameliorated, and IR-induced ROS levels were reduced. iMSC CM augmented tube formation in cocultures of hCMEC/D3 and iMSCs. Consistently, iMSC CM facilitated angiogenesis in a zebrafish model in vivo. Furthermore, iMSC CM suppressed IR-induced NFκB activation, TNF-α release, and ROS production in THP1 cells. Additionally, iMSC CM diminished NF-kB activation in THP1 cells cocultured with irradiated hCMEC/D3, iMSCs, or HMC3 microglial lines. The cytokine array revealed that iMSC CM contains the proangiogenic and immunosuppressive factors MCP1/CCL2, IL6, IL8/CXCL8, ANG (Angiogenin), GROα/CXCL1, and RANTES/CCL5. Common promoter regulatory elements were enriched in TF-binding motifs such as androgen receptor (ANDR) and GATA2. hCMEC/D3 phosphokinome profiling revealed increased expression of pro-survival factors, the PI3K/AKT/mTOR modulator PRAS40 and β-catenin in response to CM. The transcriptome analysis revealed increased expression of GATA2 in iMSCs and the enrichment of pathways involved in RNA metabolism, translation, mitochondrial respiration, DNA damage repair, and neurodevelopment. Conclusions: The iMSC secretome is a comodulated composite of proangiogenic and immunosuppressive factors that has the potential to alleviate radiation-induced vascular endothelial cell damage and immune activation.
