| regulation of cell survival and death during flavivirus infections. | flaviviruses, ss(+) rna viruses, include many of mankind's most important pathogens. their pathogenicity derives from their ability to infect many types of cells including neurons, to replicate, and eventually to kill the cells. flaviviruses can activate tumor necrosis factor α and both intrinsic (bax-mediated) and extrinsic pathways to apoptosis. thus they can use many approaches for activating these pathways. infection can lead to necrosis if viral load is extremely high or to other types of c ... | 0 | 24921001 |
