Webtrinsic mechanism of virally induced apoptosis, it has been noted that FasL and TRAIL are auto- and paracrine inducers by activating their respective receptor signaling system [23–26]. For a long time, apoptosis was regarded mainly as a host cell defense mechanism, as many viruses express antiapoptotic pro-teins to prevent this cellular response. WebAntiviral transcriptional responses and regulated cell death are crucial components of the host response to virus infection. However, in contrast to the signaling pathways that … WebIn recent years, it has become clear that in an attempt to prevent viral replication, viral dissemination or persistent viral infection of the cell, many of these protective measures actually involve the induction of programmed cell death, or apoptosis. david rayner insurance
