Abstract:
The innate nonspecific immunity is the first line of defense against viral infection. Toll-like receptors (TLRs) and retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are two main receptor families detecting viral nucleic acid. So far, three RLR family members were characterized: RIG-I, MDA5 and LGP2. RLR constitute a family of cytoplasmic helicases, which recognized intracellular single-stranded and double-stranded RNA that is introduced to cytosol during viral infection and replication. In this work we review the current knowledge about the mechanisms of viral recognition by RIG-I-like receptors and their signaling pathways for the activation of type I interferons and pro-inflammatory cytokines synthesis.

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...
