Summary

Highly active antiretroviral therapy suppresses HIV-1, but drug-resistant mutants emerge. Research is developing novel inhibitors to overcome resistance caused by over 200 mutations in reverse transcriptase inhibitors and protease inhibitors.

Area of Science:

  • Virology
  • Molecular Biology
  • Pharmacology

Context:

  • Highly active antiretroviral therapy (HAART) with reverse transcriptase inhibitors (RTIs) and protease inhibitors (PIs) is standard for HIV-1 treatment.
  • Emergence of drug-resistant HIV-1 mutants leads to treatment failure despite viral load suppression.

Purpose:

  • To review the challenges posed by drug-resistant HIV-1 mutants.
  • To highlight research efforts in understanding and overcoming antiviral drug resistance.

Summary:

  • Over 200 amino acid mutations conferring resistance to anti-HIV-1 drugs have been identified.
  • Molecular mechanisms underlying resistance to specific RTIs and PIs are increasingly understood.
  • Novel inhibitors targeting resistant HIV-1 strains are under clinical investigation.

Impact:

  • Advances in understanding HIV-1 drug resistance mechanisms.
  • Development of next-generation antiretroviral therapies effective against resistant strains.
  • Potential for improved treatment outcomes in patients with multidrug-resistant HIV-1 infections.
