Hypothesis

Can a topical microbicide gel formulation of the CCR5 antagonist maraviroc prevent HIV-1 vaginal transmission in humanized mice?

Conclusion

The maraviroc gel fully protects humanized mice against vaginal HIV-1 challenge.

Supporting Evidence

  • Maraviroc gel treated mice were fully protected against vaginal HIV-1 challenge.
  • Placebo gel treated mice all became infected by the fifth week post challenge.
  • No evidence of infection was seen in maraviroc treated mice throughout the 16-week observation period.

Takeaway

A special gel made from a medicine called maraviroc can stop mice from getting HIV when it's put in their vagina before they are exposed to the virus.

Methodology

Female RAG-hu mice were treated with maraviroc gel or placebo gel before being challenged with HIV-1 vaginally, and their infection status was monitored.

Limitations

The study is limited to a small animal model and may not fully represent human responses.

Participant Demographics

Female RAG-hu mice were used in the study.
