Researchers Exploring New Strategies To Fight Viruses, Including HIV, New York Times

Article Date: 29 Mar 2007 - 4:00 PDT
Some researchers are exploring new strategies to fight viruses, including HIV, that aim to "wipe them out by luring them to their destruction," the New York Times reports. According to the Times, viruses such as HIV invade a cell by latching onto certain proteins on the cell's surface.

Once inside a cell, viruses manipulate the cell into making new copies of themselves. Viruses cannot infect red blood cells because as these cells develop into bone marrow, they lose their DNA. If a virus enters a red blood cell, there are no genes it can use to replicate itself, the Times reports.

In one strategy, Paul Turner, an evolutionary biologist at Yale University, and colleagues created a mathematical model to predict how a virus called phi-6 -- which normally infects a species of bacteria called Pseudomonas phaseolica -- would survive if they added a mutant form of P. phaseolica that attracts viruses but does not allow it to enter and replicate. The researchers found that after introducing three rounds of mutant colonies, the virus disappeared. According to the Times, Turner is using the results to study the effects on HIV. He is adding CD4+ T cells to the surface of red blood cells with the aim of developing an HIV trap, the Times reports. "Once we have [an HIV trap], we can test whether they truly attract HIV," Turner said, adding, "And then we can set up experiments like the ones we've done with" P. phaseolica. According to the Times, the next step in Turner's research is to mix engineered red blood cells with normal CD4 cells in the laboratory and determine if they can trap HIV.

Turner said that it might be possible to provide HIV-positive people with transfusions of engineered red blood cells, which would lure the virus away from CD4 cells and allow their immune systems to recover. Dominik Wodarz -- an expert on virus ecology at the University of California-Irvine who was not involved in the research -- said that although it is a "very exciting concept," the ultimate success of such a strategy would depend on the details of HIV infection. According to Wodarz, one milliliter of blood can contain as many as 10 million copies of HIV at some stages of infection. "I don't know if it would be possible to put enough traps in," he added. Turner said that the "data are exciting, but there are all these other intricacies that you have to address." He added that even if the virus is not completely destroyed, reducing viral loads would have significant benefits (Zimmer, New York Times, 3/27).

Aspirin may cut Staph risk in dialysis patients

Last Updated: 2007-03-28 13:32:38 -0400 (Reuters Health)

NEW YORK (Reuters Health) - Aspirin therapy may protect people on dialysis from infection with the potentially life-threatening bug Staphylococcus aureus.

Based on lab studies showing that aspirin has direct anti-Staph effects, Dr. Martin Sedlacek, from Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, and colleagues theorized that long-term aspirin therapy might reduce the risk of Staph infections in at-risk dialysis patients.

A look at more than 4,700 blood cultures obtained from 872 patients confirmed their theory. Staph infections occurred significantly less often in patients taking aspirin daily to prevent blood clots compared with those not taking aspirin.

The anti-Staph benefit of aspirin therapy was primarily seen with a regular dose of asprin rather than a baby aspirin, the authors note.

In the final analysis, aspirin use lowered the risk of Staph infection by 54 percent. Aspirin therapy was also linked to a reduced risk of a infection with methicillin-resistant Staph aureus, or MRSA, the hard-to-treat version of the bug.

Aspirin therapy, however, seemed to have no effect on the occurrence of infections by other microbes.

The findings, Sedlacek and colleagues conclude, "strongly support" the need for a forward-looking study of aspirin treatment in dialysis patients and other populations at increased risk of Staph infections.
