Researchers at Lund University in Sweden have discovered a new method to treat human herpes viruses. The new broad-spectrum method targets physical properties in the genome of the virus rather than viral proteins, which have previously been targeted. The treatment consists of new molecules that penetrate the protein shell of the virus and prevent genes from leaving the virus to infect the cell. It does not lead to resistance and acts independently of mutations in the genome of the virus. The results are published in the journal PLOS Pathogenes.
