Researchers Discover Gene That Blocks HIV

stemceller writes to tell us that a team of researchers at the University of Alberta claims to have discovered a gene capable of blocking HIV thereby preventing the onset of full blown AIDS. "Stephen Barr, a molecular virologist in the Department of Medical Microbiology and Immunology, says his team has identified a gene called TRIM22 that can block HIV infection in a cell culture by preventing the assembly of the virus. 'When we put this gene in cells, it prevents the assembly of the HIV virus," said Barr, a postdoctoral fellow. "This means the virus cannot get out of the cells to infect other cells, thereby blocking the spread of the virus.'"

    That research lab at Alberta is know for releasing under-researched findings before complete testing is applied. I also want to point out that it would be near impossible to make anything but a vaccine out of this discovery. So people already having aids with be out of luck, regardless of what TFA says.

    There are a lot of things that block HIV in cell culture.

    Yet after literally hundreds of millions in financing, there isn't yet any real curative treatment. Why? Because HIV is a retrovirus with one of the worst polymerases known. It's just so bad at copying itself, that any treatment applied in-vivo acts only as a selective pressure.

    Same is the case for HIV vaccines - even though there ARE conserved regions of the virus, they aren't very good targets, and the ones that are good targets are too antigenically fluid to be targeted.

    In the end, my opinion as a virologist is that stopping the spread of HIV, and continuing to develop a larger palette of inhibitors are the proper solutions to the HIV problem. If we treat the people who have been infected, and don't infect any more... HIV will not be a problem after 2 generations.

      It's possible... but ironically it's likely to happen if Africa continues to receive inadequate quantities of drugs. You see, evolution only works this way, when the mutations you're looking for provide a reproductive advantage. If we can treat HIV-infected patients in such a way that allows them to successfully reproduce (and modern medications taken appropriately already do), then there is no selective pressure for such a resistance to develop. Even if a minor selective pressure does exist, it's not significant enough to cause a shift in dominant genes rapidly enough to provide us with natural immunity before our knowledge of biology will surpass the ability of HIV to fight back.

  3. Delta 32 gene marker is a natural immunity already by retech · · Score: 5, Informative

    People who survived the Plague in Europe either did not encounter it or almost universally had a genetic anomaly commonly referred to as the delta-32 marker. Their ancestors survive other diseases because of this causing what amounts to an odd protein binding issue on the cellular level. Those people are also naturally immune to HIV.

  4. Re:How to filter low impact science by Rhabarber · · Score: 5, Informative

    PLoS Pathogens currently has an ISI Impact Factor of 6.1.
    This is not comparable to to Nature, Science or PLoS Biology but for a specialized journal it's quite high.

    The good thing about the PLoS Journals is that they rank quite high _and_ the articles are open accessible by day one. This means that an ordinary slashdot user (not sitting in a rich lab or library that has spent truckloads of money to access the most important journals in its field) has the chance to _read_ the f#@*ing primary resarch article.

    As said, the paper is here although the site is down for maintenance at the moment ;).
