NLRP3 activation by Leishmania parasites is critical to the outcome of the disease. Here the authors show that LRV, a virus infecting Leishmania strains associated with more severe human disease, enables the parasite to suppress the inflammasome by activating type 1 interferon through TLR3, which leads to autophagy-mediated NLRP3 degradation.
