Cell-based gene therapy against HIV.

The ability to integrate inside the host genome lays a strong foundation for HIV to play hide and seek with the host's immune surveillance mechanisms. Present anti-viral therapies, although successful in suppressing the virus to a certain level, fail to wipe it out completely. However, recent approaches in modifying stem cells and enabling them to give rise to potent/resistant T-cells against HIV holds immense hope for eradication of the virus from the host. In this review, we will briefly discuss previous landmark studies on engineering stem cells or T-cells that have been explored for therapeutic efficacy against HIV. We will also analyze potential benefits and pitfalls of some studies done recently and will share our opinion on emerging trends.
