Current Antiviral Strategies and Emerging Gene-Editing Approaches for Treating Herpes Simplex Virus Infections
The standard antiviral agents work by being converted into active compounds that interfere with the viral DNA polymerase, thereby halting the replication process. They are highly effective during the lytic phase when the virus is actively replicating and causing symptoms. However, the viral genome, known as the **latency-associated transcript (LAT)**, remains dormant within the nerve cells, ready to reactivate under conditions of stress or immunosuppression.
Emerging research is now focused on molecular mechanisms to permanently address this latency. One of the most promising avenues is the use of **gene-editing technologies**, such as CRISPR-Cas9, to precisely locate and excise the large, circularized latent viral DNA from the host cell’s nucleus. Preclinical studies have demonstrated success in eliminating substantial portions of the latent viral load in animal models, representing a significant scientific breakthrough. Other novel approaches include **therapeutic vaccines** aimed at generating a robust T-cell mediated immune response to continuously keep the…
