Researchers are hunting for clues to why one person develops the disease while others merely harbor the virus. Some investigators suspect that additional viral infections may play a role as accomplices or triggers. The main suspects: Epstein-Barr virus and cytomegalovirus (both members of the herpes family) and the virus that causes hepatitis B. The difficulty, says Lange, comes in determining whether such viruses are in fact co-agents of AIDS or merely tagalong infections...
...Kanki $107 million to fight AIDS in Africa as part of the President’s Emergency Plan For AIDS Relief (PEPFAR), the government program entrusted with disbursing $15 billion to help eradicate AIDS in Africa. The grant commits Harvard to treating thousands of patients a year with anti-viral drugs and implementing clinical drug delivery mechanisms in three African countries—Botswana, Nigeria, and Tanzania...
...serious disorder that afflicted half of Schwartz and Kagan's shy subjects. In addition, a 2003 study of HIV-positive men at UCLA showed that patients who scored high on a social-inhibition and irritability scale may have a worse overall prognosis than their easier-going peers, with a viral load fully eight times as high. While it's not easy to generalize those findings to the HIV-negative population, the study does suggest that shyness may take a toll on the immune system...
...that's exactly what Dr. Stephen Russell was hoping for. A cancer specialist at the Mayo Clinic, Russell does everything he can to aid and abet those viral bandits. He arms them with detailed instructions for finding their target cells and outfits them with specially designed protein keys to speed up entry. As far as he's concerned, those viruses are the good guys, since the cells they are attacking and destroying are cancer cells in a fast-growing tumor...
...Epstein-Barr virus (EBV). More than 95% of the population is infected with EBV, a usually benign microbe that sequesters itself in the immune system's B cells. Like any other cellbound virus, EBV doesn't remain dormant for long, dividing furiously and emerging in runaway viral mobs. But unlike most other viruses, EBV is quickly eliminated by the vigilant immune system's killer T cells...
