Gene therapy reverses heart damage

"Long-term gene therapy has found to be effective in improving cardiac function and reversing heart damage in heart failure. During the study, the researchers treated the rats with a gene that generates a peptide called ARKct, which was administered to hearts in combination with recombinant-adeno-associated virus serotype 6 (rAAV6.) ARKct works by inhibiting the activation of G protein-coupled receptor kinase 2 (GRK2)." - Zeenews.com
