Abstract:
The first line of defense against viral infections is mediated by interferons (IFN)s, which are produced rapidly by the infected host. Type I IFNs (IFN-alpha/beta) are known to combat viruses both directly by inhibiting viral replication in the cells and indirectly by stimulating the innate and adaptive immune responses. Recently, a novel class of cytokines was discovered and named IFN-lambda (alternatively type III IFN or interleukin-28/29 [IL- 28/29]), based on IFN-like antiviral activity and induction of typical IFN-inducible genes. Here, we review the literature on IFN-lambda and discuss the current knowledge of the functions and mechanisms of action of IFN-lambda.

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...
