Gene therapy strategies: can we eradicate HIV?

Area of Science:

• Molecular Biology
• Immunology
• Gene Therapy

Background:

• Antiretroviral combination therapy has advanced but cannot eradicate HIV.
• Lifelong HIV treatment poses risks of toxicity, adherence issues, and drug resistance.
• Gene therapy presents an attractive alternative strategy for achieving HIV eradication.

Purpose of the Study:

• To review gene therapy approaches for HIV eradication.
• To identify obstacles and potential solutions for effective gene therapy in HIV.
• To highlight recent advancements and future prospects in HIV gene therapy.

Main Methods:

• Review of current gene therapy strategies targeting HIV.
• Analysis of limitations including low transduction efficiency and genotoxicity.
• Exploration of novel vector systems, target cells, and transduction protocols.

Main Results:

• New transgenes offer in vivo selection advantages for transduced cells.
• Restoration of an HIV-resistant immune system is a key development.
• A case study of HIV eradication post-stem cell transplant with CCR5 delta 32 mutation shows proof of concept.

Conclusions:

• Gene therapy holds significant potential for HIV eradication.
• Overcoming current technical challenges is crucial for clinical success.
• Emerging strategies and understanding genetic resistance mechanisms offer hope for a functional cure.
