This story just appeared but the real import of the article was hidden. Despite the billions and the best efforts of many of the world's best scientists, why don't we have a vaccine? Why has it been it so hard to get a vaccine that works against AIDS? The reason is because AIDS viruses incorporate themselves into the genetic code and can pass from cell to cell without having to transmute back into a virus (Source (http://www.aegis.com/news/ct/1987/CT870501.html)).

The particular approach reported in the following article is a Zinc finger DNA-binding protein nucleases (ZFN) designed to disrupt the CCR5 gene, coding for the receptor that allows HIV entrance into cells. Developed by Sangamo Biosciences, this is a new approach to treating AIDS by targetting the molecular receptor needed for HIV entry into cells (Source (http://phx.corporate-ir.net/phoenix.zhtml?c=120938&p=irol-newsArticle&t=Regular&id=796820&)).
They initiated the phase 1 trial of this treatment in December 2005.

U.S. experiment uses AIDS to fight AIDS

WASHINGTON (Reuters) - An AIDS virus genetically engineered to fight other AIDS viruses worked better than expected, suppressing the virus and renewing the immune systems of a few patients, researchers reported on Monday.

The study involved just five people, and such an approach needs years more study, they cautioned -- but the surprising results offer new hope both for the field of gene therapy and for treating the fatal and incurable AIDS virus.

"The goal of this phase I trial was safety and feasibility and the results established that," said Dr. Carl June of the University of Pennsylvania School of Medicine, who led the study.

"But the results also hint at something much more," he added.

"It seemed to have a vaccine-like effect in that the immune system was better in most of the patients than when they enrolled. We are trying to study the mechanism."

the scientist are doing their job ,but without enough support from the goverment they cannot cure diseases.god bless them and lets hope for better politicians all over around the world.

It also hints at wider applications:



It is hoped the approach could be adapted to tackle other diseases.
The researchers believe the use of viruses like HIV, lentiviruses, may prove particularly effective in gene therapy. Lentiviruses are especially effective at infecting T cells, and also infect non-dividing or slowly dividing cells, raising the prospect that they could be used to target neurons or stem cells.

There has been a great deal of fear concerning gene therapies. What most people don't realize is that viruses have perfected gene therapy and that is what they are doing to us. The most successful viruses, such as the AIDS virus, are doing gene therapy on millions of people, every day. The only way to fight back will be gene therapy.

Agreed, retroviruses are probably the most effective tool in the biotechnologist's box. They have been used for some time to genetically modify bacterial cells to produce non-bacterial proteins so I guess it stands to reason that they should be useful to modify eukaryotic cells in the fight against conditions caused by other viruses or gnetic defects.

Looks like this is the only way to go :(

It's like fighting fire with fire when it's to severe to fight with water.

The virologists are getting closer and closer. A good thing. And will be needed with who knows what in the future of viruses. They only get meaner and tougher as time goes by.
