The latest edition of the Journal of Virology featured a study by Hector Aguilar-Carreno details how two highly lethal viruses, Nipah and Hendra, have greater pathogenic potential when their cell-sabotaging proteins are combined. Aguilar-Carreno’s lab is also working on related research that may lead to vaccine-free therapies or improved vaccines to treat enveloped viruses, which include infectious diseases such as HIV and influenza.
