For more than two decades, scientists of Center for Scripps Research, in the United States, they work with an ambitious look in mind: to create a HIV vaccine. And while the goal has not been completed, there are developments that make them believe they are close to delivery.
The most recent is to develop a experimental vaccine who have had a great response in chimpanzees whose organism is very similar to humans. This vaccine sprays special antibodies that do not neutralize HIV stress that is most commonly infected by people, known as Tier 2 Virus.
"We found that this type of neutralization antibody, which is presented to the body with a vaccine, can protect animals from viruses that look very similar to HIV in the real world," he said. doctor. Dennis Burton, head of the Center's Immunology and Microbiology Department.
Discovering these antibodies is in line with the work that the Scripps Research Center has done since 1990: identify those vulnerable areas that HIV has and help the immune system to create specific antibodies to attack in those areas.
"Since the emergence of HIV, this is the first scientific test that antibodies based defense against Tier 2 stress stressed HIV," said one of the study's authors. "The question is the restHow can we achieve these same results in chimpansein and other animals? "
At present, the vaccine will continue in a period of experimentation with animals and its creatures hope that they will have an authorization to begin soon testing with people
