On the cover: Mutant forms of HIV-1 IN reduce the therapeutic effectiveness of integrase strand transfer inhibitors (INSTIs). The cover figure shows the IN of prototype foamy virus complexed to a novel INSTI (gold) that retains potency against resistant mutants of HIV-1 IN. Overlain are the host and viral DNA substrates (blue and green, respectively), showing substrate mimicry by the inhibitor.
