| Resumo: | Currently, there are no antiviral strategies to rapidly respond to novel emerging viruses or to mosquito borne viruses. On this thesis we have developed an innovative artificial circular RNA (circRNA) antiviral platform that targets highly conserved RNA structures within the genomes of positive-strand RNA viruses. We have generated highly efficient antiviral circRNA molecules tested in cell culture against HCV, DENV, WNV and SARS CoV-2 viruses. Moreover, we demonstrated the anti-SARS CoV-2 activity of circRNAs in infected hamsters. Besides virus-specific circRNAs, we also generated a broad-spectrum circRNA against both WNV and DENV viruses. Remarkably our platform circRNA platform was also effective in addressing genetic diseases associated with aberrant RNA structures, as demonstrated in a cell culture model of the Steinert Syndrome, the most common form of muscular dystrophy. Taking together these findings highlight the versatility and significant therapeutic potential of our circRNA platform, providing a promising avenue for addressing current and future viral threats as well as genetic diseases. |
