Abstract:
Pro-inflammatory cytokines are important mediators in immune responses against invading pathogens, including viruses. Precursors of the pro-inflammatory cytokines interleukin (IL)-1β and IL-18 are processed by caspase-1. Caspase-1 is activated through autocleavage, but how this is regulated remained elusive for a long time. In 2002, an intracellular multimeric complex was discovered that facilitated caspase-1 cleavage and was termed 'inflammasome'. To date, different inflammasomes have been described, which recognize a variety of ligands and pathogens. In this review, we discuss the role of inflammasomes in sensing viral infection as well as the evasion strategies that viruses developed to circumvent inflammasome-dependent effects.

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...
