To understand more fully how this alternative splicing event correlates with the cellular innate immune response during RVFV infection, WT HEK 293 cells were infected with RVFV MP12 and harvested at 6, 12, 18, 24, and 30 h.p.i. Relative normalized expression of IFNβ, IL-8, and TNFα throughout infection were measured in parallel with assessment of alternative splicing at each timepoint. This evidence concerns the gene TNF and infection.
