Gene drives are genetic tools created to spread specific modifications through populations, and a new approach has been developed for herpesviruses that uses co-infection of engineered and wild-type viruses.*
-
This research focused on a gene drive targeting human herpes simplex virus 1 (HSV-1), demonstrating its ability to propagate in cell cultures and during infections in mice, particularly affecting neuronal tissues.*
-
The study revealed significant co-infection and recombination rates in HSV-1, suggesting that these gene drives could serve as potential therapies by effectively spreading genetic modifications during viral infections.*
