The presence of polybrominated diphenyl ethers (PBDEs) in the aquatic environment is an issue of major concern which may be a cause of increasing prevalence and severity of diseases in marine mammals. Although, cell culture model development and in vitro investigation approach is a prime need of time to progress immunotoxic research on aquatic mammals. In this study, we stablished fibroblast cell line (pantropic spotted dolphin) to assess the potential effects of PBDEs on cytokines response. Cells were grown in 6 well cell culture plate and complete media (DMEM and Ham's F12 nutrient mixture, fetal bovine serum, antibiotic and essential amino acids) was provided. The primary culture of (PSP-LWH) cells identification was achieved by vimentin (gene and protein) expressions. Karyotyping revealed pantropic spotted dolphin chromosomes 20 pairs with XX. Transfection was achieved by SV40 LT antigen and transfected cells were expended for passages. Stability of cell line was confirmed at various passages intervals using RT-PCR, western blotting and immunofluorescence methods. After confirmation, cell line was exposed to BDE-47 (250 ng/ml), BDE-100 (250 ng/ml) and BDE-209 (1000 ng/ml), with control group (PBS), positive control DMSO (0.1%) and negative control LPS (500 ng/ml) for 24 h. The ELISA results showed significant increase in IL-6 in BDE- 100 and BDE-209 while IL-1β and IL-8 were found higher in BDE-47 and BDE-100. TNFα and IL-10 secretion was noted higher in control and positive control groups. Altogether, these results emphasize importance of transfected (PSP-LWHT) cell line in aquatic research and potential effects of PBDEs on fibroblast provides evident to understand immune modulating effects of PBDEs in marine mammals. The impact of PBDEs on dolphin’s fibroblast cells immune response and altered cytokine response have been presented for the first time.

泛斑海豚(Stenella tensa)成纤维细胞系的建立及多溴联苯醚(PBDEs)对细胞因子应答的潜在影响

在水生环境中多溴二苯醚(PBDEs)的存在是一个主要关注的问题,这可能是海洋哺乳动物疾病的流行和严重程度增加的原因。虽然,细胞培养模型的开发和体外研究方法是进行水生哺乳动物免疫毒性研究的主要时间需求。在这项研究中,我们建立了成纤维细胞系(泛斑斑海豚)以评估PBDEs对细胞因子反应的潜在影响。细胞在6孔细胞培养板中生长,并提供完全培养基(DMEM和Ham's F12营养混合物,胎牛血清,抗生素和必需氨基酸)。(PSP-LWH)细胞鉴定的原代培养是通过波形蛋白(基因和蛋白质)表达来实现的。核型分析揭示了与20条XX呈对生的斑点状海豚染色体。通过SV40 LT抗原实现转染,并将转染的细胞用于传代。使用RT-PCR,蛋白质印迹和免疫荧光方法在不同传代间隔证实了细胞系的稳定性。确认后 将细胞系暴露于BDE-47(250 ng / ml),BDE-100(250 ng / ml)和BDE-209(1000 ng / ml),对照组(PBS),阳性对照DMSO(0.1%)和阴性对照LPS(500 ng / ml),持续24小时。ELISA结果显示BDE-100和BDE-209中IL-6明显增加,而BDE-47和BDE-100中IL-1β和IL-8较高。对照组和阳性对照组的TNFα和IL-10分泌较高。总之,这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。BDE-100(250 ng / ml)和BDE-209(1000 ng / ml),以及对照组(PBS),阳性对照DMSO(0.1%)和阴性对照LPS(500 ng / ml),持续24小时。ELISA结果显示BDE-100和BDE-209中IL-6明显增加,而BDE-47和BDE-100中IL-1β和IL-8较高。对照组和阳性对照组的TNFα和IL-10分泌较高。总之,这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。BDE-100(250 ng / ml)和BDE-209(1000 ng / ml),以及对照组(PBS),阳性对照DMSO(0.1%)和阴性对照LPS(500 ng / ml),持续24小时。ELISA结果显示BDE-100和BDE-209中IL-6明显增加,而BDE-47和BDE-100中IL-1β和IL-8较高。对照组和阳性对照组的TNFα和IL-10分泌较高。总之,这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。ELISA结果显示BDE-100和BDE-209中IL-6明显增加,而BDE-47和BDE-100中IL-1β和IL-8较高。对照组和阳性对照组的TNFα和IL-10分泌较高。总之,这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。ELISA结果显示BDE-100和BDE-209中IL-6明显增加,而BDE-47和BDE-100中IL-1β和IL-8较高。对照组和阳性对照组的TNFα和IL-10分泌较高。总之,这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。这些结果强调了转染的(PSP-LWHT)细胞系在水生研究中的重要性,而多溴二苯醚对成纤维细胞的潜在作用为了解多溴二苯醚在海洋哺乳动物中的免疫调节作用提供了明显证据。PBDEs对海豚成纤维细胞免疫应答和细胞因子应答改​​变的影响已首次报道。
