Ddx21 innate immunity

WebDec 22, 2024 · Innate immunity is the first line of the cellular host to defend against viral infection. Upon infection, viruses can be sensed by the cellular host’s pattern recognition receptors (PRRs), leading to the activation of the signaling cascade and the robust production of interferons (IFNs) to restrict the infection and replication of the viruses. … WebApr 29, 2016 · Successful DENV infection relies on its ability to evade the host innate immune system. By using iTRAQ labeling followed by LC-MS/MS analysis, DDX21 was identified as a new host RNA helicase involved in the DENV life cycle. In DENV infected cells, DDX21 translocates from nucleus to cytoplasm to active the innate immune …
