Targeting ARF4-mediated intracellular transport as broad-spectrum antivirals
Abstract Host factors that regulate cellular vesicular trafficking also contribute to progeny virions’ destination, thus representing as potential antiviral drug targets. Here we demonstrate that genetic deletion of ARF4, a regulator in vesicle transport, repressed multiple pathogenic RNA viral infections including Zika virus (ZIKV), influenza A virus (IAV), SARS-CoV-2 and Vesicular Stomatitis virus (VSV). ARF4 activation was stimulated upon viral infection, and viral production was rescued when reconstituted with the activated ARF4, but not the inactivated mutants. Mechanically, ARF4 deletion obstructed viral normal translocation into Golgi complex, but led to mis-sorting for lysosomal degradation, consequently caused the blockage of final release. More importantly, ARF4 targeting peptides achieved significant therapeutic efficacy against ZIKV and IAV challenge in mice by blocking ARF4 activation. Hence, we clarify the critical role of ARF4 during viral infection, providing a broad-spectrum antiviral target and the basis for further pharmaceutical development..
