Fighting mosquito-borne diseases: Scientists pinpoint drug target for dengue, zika & other viruses

economictimes.indiatimes.com:

mosquito-transmitted viruses, including dengue and Zika, hijack host cells to promote their own reproduction. The research, published recently in the journal Cell Host and Microbe, paves the way for developing new therapeutics for these infections with no or very limited treatments. «Our findings bring us one step closer to understanding and treating currently untreatable mosquito-transmitted pathogens, which are an ever-increasing threat to global human populations,» said Michaela Gack, Scientific Director of Cleveland Clinic's Florida Research & Innovation Center. «Our commitment to studying viral pathogens and host enzymes in novel ways may ultimately help us develop new, effective treatments to prevent future threats to human health,» Gack said in a statement. Viruses cannot survive on their own. While they contain their own genetic material, they don't carry all the genes or factors they need to live and reproduce. That is why viruses infect hosts — they hijack mammalian cells to turn them into virus-making factories. To take control of the infected host cell, the Zika virus, for example, hijacks several proteins inside the cell for its efficient replication.
