UTSW Makes Breakthrough In HIV Prevention

DALLAS (CBS 11 / TXA 21) ― Every day, an estimated 7,000 women around the world are infected with HIV.

But researchers at UT Southwestern hope to change that statistic with a breakthrough in the prevention of HIV transmission.

Humanized mice, which have the same immune systems and infection fighting cells as humans, were given antiretroviral drugs and then infected vaginally with HIV. The study was a 100 percent effective, and the mice did not get infected.

Currently, antiretroviral pills are taken by HIV and AIDS patients to prevent the virus from duplicating.

The possibility of not having to create a new drug to prevent a deadly disease is what really excites Dr. Victor Garcia, the senor author of the study.

"The drugs are already approved. Patients use them everyday. We can go from treatment to prevention," said Dr. Garcia.

Even though the testing was 100 percent effective in humanized mice, it will be another year before knowing the results from the clinical trails on humans.
