1 Perfluorooctane sulfonate mediates microglial activation and secretion of TNF-alpha through Ca2+-dependent PKC-NF-kB signaling. perfluorooctane sulfonic acid tumor necrosis factor Homo sapiens
2 In our research, we found that HAPI microglia secreted tumor necrosis factor-alpha (TNF-alpha) after PFOS exposure in time-dependent and dose-dependent way. perfluorooctane sulfonic acid tumor necrosis factor Homo sapiens
3 In our research, we found that HAPI microglia secreted tumor necrosis factor-alpha (TNF-alpha) after PFOS exposure in time-dependent and dose-dependent way. perfluorooctane sulfonic acid tumor necrosis factor Homo sapiens
4 It was noteworthy here the secretion of TNF-alpha mediated by PFOS was blocked by Ca(2+) inhibitor and protein kinase C (PKC) inhibitor. perfluorooctane sulfonic acid tumor necrosis factor Homo sapiens
5 Finally, through treating SH-SY5Y cells with PFOS-treated microglial conditioned medium, we demonstrated that TNF-alpha mediated neuronal apoptosis. perfluorooctane sulfonic acid tumor necrosis factor Homo sapiens
6 To sum up, our research had shown, for the first time, that the distinct TNF-alpha secretion brought by PFOS in HAPI microglia, was achieved through the Ca(2+)-dependent PKC-NF-kB signaling, subsequently participating in neuronal loss. perfluorooctane sulfonic acid tumor necrosis factor Homo sapiens
