Preventing the spread of HIV/AIDS with humanized BLT mice
Date:5/18/2011

BLT mice reproduced the CAPRISA experimental design with tenofovir. The researchers say they "observed "88 percent protection of vaginal HIV-1 transmission," which was further confirmed by lack of detectable virus anywhere in the animals.

The researchers then tested six additional microbicide drug candidates for their ability to prevent vaginal HIV transmission. These experimental compounds, not yet tested in people, interfere with the virus' ability to reproduce. Partial or complete protection was shown by all but one of these drug candidates. Based on these positive results, Denton said these inhibitor drugs warrant serious consideration for future testing in people.

"This animal model has great potential value for testing and predicting the HIV preventive benefits of the second generation of microbicide candidates that are aimed at preventing viral replication," Garcia said. "The results of these studies will help provide important information for current and future clinical trials."
