Impact of PrPC depletion on cell sensitivity to sTNFα in 1C11 precursor cells, 1C115-HT neuronal cells and primary CGNs.
LD50 TNFα (ng ml−1) | ||
---|---|---|
WT | PrPnull/PrP0/0 | |
1C11 | 70 ± 10 | 8.1 ± 1.5 |
1C115-HT | 8.1 ± 1.2 | 1.5 ± 0.3 |
CGN | 100 ± 20 | 5.2 ± 3.1 |
LD50 TNFα values correspond to the concentration of sTNFα inducing a 50% cell death in 1C11 and 1C115-HT cells or inducing dendritic fragmentation for 50% of neuronal cells in CGNs. Data are the mean ± SEM of three independent experiments performed in triplicate.
