Abstract:
Type I interferons (IFN-I) orchestrate numerous biological and cellular processes and are essential elements during host antiviral defense. After recognition of highly conserved virus signatures, a complex network of signaling events is rapidly initiated and leads to IFN-I synthesis. These cytokines directly induce a strong antiviral state and exert several immune-regulatory actions aimed at preventing virus spread. On the other hand, viruses evolved to evade or subvert the IFN-I system for their own benefit. In the present article, we review selective aspects of IFN-I induction and functions during several viral infections and discuss the beneficial and detrimental roles of IFN-I illustrated during lymphocytic choriomeningitis virus (LCMV) infection in its natural host, the mouse.

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...
