Susceptibility of Enterovirus-D68 to RNAi-mediated antiviral knockdown.
Abstract Enterovirus D68 (EV-D68) represents an emerging pathogen which has demonstrated a capacity for causing epidemic illness in pediatric and immunocompromised patients. With no effective antiviral treatment available, therapeutic interventions are currently limited to supportive care. Utilizing available genomic sequences from the 2014 B3 Epidemic EV-D68 clade and the 1962 Fermon EV-D68 strains, we performed in silico comparative genomic analysis, identifying several islands of phylogenetic conservation within the viral RNA-dependent RNA polymerase gene. The effects of transfecting short-interfering double-st...

Antiviral screen identifies EV71 inhibitors and reveals camptothecin-target, DNA topoisomerase 1 as a novel EV71 host factor.
Abstract Enterovirus 71 (EV71) is one of the causative agents of hand, foot and mouth disease (HFMD) associated with severe neurological disease. EV71's pathogenesis remains poorly understood and the lack of approved antiviral has led to its emergence as a clinically important neurotropic virus. The goals of this study were to: (i) identify novel anti-EV71 compounds that may serve as lead molecules for therapeutics; and (ii) investigate their targets in downstream studies. We screened a 502-compound library of highly purified natural products for anti-EV71 activities in a cell-based immunofluorescence assay that w...
