Ectopic expression of adenovirus VA RNAI is sufficient to inhibit the release of pro-inflammatory cytokines. (A) Western blot analysis of NLRP3 inflammasome-activated (LPS + ATP treated) THP-1 cells infected with replication deficient AdEasyWT or AdEasyΔVAI demonstrating a VA RNAI-dependent decrease of caspase-1, Il-1ß, and HMGB1 release. (B) Western blot analysis demonstrating the inhibition of caspase-1, Il-1ß, and HMGB1 release in NLRP3 inflammasome-activated (LPS+ATP treated) THP-1 cells transfected with in vitro transcribed VA RNAI. Ctrl RNA; in vitro transcribed RNA of the same size as VA RNAI, but with an unrelated sequence.
