Disrupting IFIT1-STAT2 viral evasion synergy yields live-attenuated flavivirus with enhanced immune priming
Diverse human viruses deploy a common immune-evasion strategy: viral 2'-O-methylation coupled with STAT2 antagonism. Yet the importance of this coupling and whether targeting the coupled functions offers benefits in vaccine development, remains unknown. Using deep mutational scanning of the dengue NS5 protein, we discovered that the two immune-evasion functions work synergistically to cripple interferon signaling.
Immune context unmasks regulatory effects of Neanderthal and Denisovan introgression
Neanderthal and Denisovan introgression have left a pervasive footprint in the human genome, yet its regulatory consequences remain poorly understood. Here we use a massively parallel reporter assay to characterize the cis-regulatory activity of 4,161 high-frequency introgressed variants across respiratory (A549), hepatic (HepG2), and hematopoietic (K562) cells exposed to immune and infectious stimuli. We find that ~18% of variants show differential activity between archaic and modern...
