SAN FRANCISCO (http://stphork.com/?go=san+francisco&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049) - Nearly 10 years after the development of antiviral drugs (http://josynet.com/?go=drugs&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049) to treat HIV and AIDS, scientists are poised to attack the deadly virus (http://timinthq.com/?go=virus&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049) with a new weapon: stem cells.
Researchers at UCLA are working on ways to arm blood stem cells in the bone marrow against the HIV virus (http://postfiking.com/?go=virus&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049). Though the strategy doesn't amount to a cure, it may be more effective than current antiviral treatments and some day might have the potential to immunize people against the virus (http://thefullm.com/?go=virus&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049).
The HIV virus (http://tumpank.com/?go=virus&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049) attacks several different types of blood cells that are part of the immune system. "If you can target the blood-forming stem cell, that cell gives rise to all blood cells," said virologist Jerome Zack of UCLA. "So, therefore, if you could protect that cell, then every other cell derived from that would be protected."
Zack presented his research Wednesday at a meeting of the Independent Citizen's Oversight Committee, the 27-member group created by Proposition 71 to direct the state of California's stem cell research program. The urgency to develop better treatments for HIV is particularly acute in San Francisco (http://josynet.com/?go=san+francisco&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049) where the disease has affected approximately 25 percent of the gay male population, said Robert Klein, chairman of the ICOC.
"Every day the situation gets worse," said Jeff Sheehy of the University of California San Francisco (http://krimbaset.com/?go=san+francisco&url1=http%3A%2F%2Fwww.fortwayne.com%2Fmld%2Ffortwa yne%2Fnews%2Fnation%2F13072746.htm&pin=37049) AIDS Research Institute and ICOC board member. "Every day 8,500 people in this world die of AIDS. Every day 14,000 new infections occur across the globe."
