Three recent experiments conducted by medical experts have developed new anti-HIV vaccine that might prevent this disease from affecting healthy human cells. Results turned out good in the tests that were carried out on lab mice, but researchers hope they could broaden the effects of the vaccine in the future.
The National Institute of Allergy and Infectious Diseases, one of the many departments working for the National Institutes of Health funded a new medical research for the improvement of the HIV treatment. The three studies that were carried out simultaneously all showed that a new anti-HIV vaccine might be developed to prevent the progression of the disease into the human body.
According to the description provided by researchers in the medical journals of Cell and Science, the experiment was conducted through a two-stage process. The first stage presupposed the artificial stimulation of lab rabbits and mice to produce antibodies against a powerful HIV strain.
John P. Moore of Cornell University and his colleague, Roger W. Sanders from the Academic Medical Center in Amsterdam told the press that they have injected the lab animals with the vaccine and observed their physical and anatomical reactions for a given period of time.
Results have shown that the animals began neutralizing the HIV strain as soon as they came across it. They further explained that the anti-HIV vaccine relies on the ability of the HIV strain to bind to cells and this method is a rater new practice.
The second research focused primarily on the abilities that the vaccine needs to have in order to neutralize HIV cells. Based on tests, physicians concluded that the vaccine has to render the immune system vulnerable at first and then, to protect it through a coax protein.
Finally, the last experiment that was conducted started from the premises of the first study, namely that HIV strains can be neutralized. This time, however, scientists wanted to make sure that this particular ability is also possible in humans, not just in lab mice.
As a consequence, the tests that were carried out during the third experiment led to the identification of the VRC01-class of antibodies which has successfully neutralized HIV strains in mice. Scientists have reasons to believe that the same class of antibodies might be formed by humans, as well.
