Abstract:
Host pattern recognition receptors (PRRs) recognize invading viral pathogens and initiate a series of signaling cascades that lead to the expression of type I interferons (IFNs) and inflammatory cytokines. During the past decade, significant progresses have been made to characterize PRRs such as Toll-like receptors (TLRs) and RIG-I-like receptors (RLRs) and elucidate the molecular mechanisms of TLR- and RLR-mediated signaling. To avoid excessive and harmful immune effects caused by over-activation of these signaling pathways, host cells adopt a number of strategies to regulate them. In addition, invading viruses also employ a variety of mechanisms to inhibit the production of type I IFNs, thereby evading the supervision and clearance by the host. In this review, we briefly summarize the TLR- and RLR-mediated type I IFN signaling and then focus on the mechanisms by which host cellular and viral components regulate the expression of type I IFNs.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
