Semen ingredient 'drastically' enhances HIV infection

A plentiful ingredient found in human semen drastically enhances the ability of the human immunodeficiency virus (HIV) to cause infection, according to a report in the Dec. 14, 2007, issue of the journal Cell, a publication of Cell Press. The findings help to understand the sexual transmission of HIV and suggest a potential new target for preventing the spread of AIDS, the researchers said.

1. Jefferson scientists find rabies-based vaccine could be effective against HIV
   04-03-2007 · EurekAlert!
   Rabies, a relentless, ancient scourge, may hold a key to defeating another implacable foe: HIV. Scientists have used a drastically weakened rabies virus to ferry HIV-related proteins into animals, in essence, vaccinating them against an AIDS-like disease. Early evidence indicates that the vaccine -- which doesn’t protect against infection -- prevents development of disease. Two years after the initial vaccination, four non-human primates were protected from disease, even after being "challenged" with a dangerous animal-human virus.

   Researchers have demonstrated HIV replication within resident immune cells of the testis, providing an explanation for the persistence of virus in semen even after effective highly active antiretroviral therapy. The related report by Roulet et al., "Susceptibility of human testis to human immunodeficiency virus-1 infection in situ and in vitro," appears in the December issue of the American Journal of Pathology.

   A novel combination therapy drastically reduces the infection rate of three prevalent viruses -- and risk of death -- in transplant patients with compromised immune systems. Trivirus-specific cytotoxic T lymphocytes (CTLs), the first multivirus killer of its kind, called, controlled infections caused by three commonplace viruses -- cytomegalovirus (CMV), Epstein-Barr virus (EBV), and adenovirus -- with no toxicity in a phase 1 trial.

   A new study suggests the effects of long-standing, undiagnosed HIV infection are hanging over a generation of adolescents in Zimbabwe, causing organ damage, chronic ill health, stunted growth, and other problems. The research demonstrates the need to reduce barriers to early testing and admission to care for these adolescents. It appears in the March 15 issue of Clinical Infectious Diseases, currently available online.

   Three related papers published in the Sept. 1 edition of the Journal of Immunology provide key new insights into the complexity of HIV/AIDS. Don Sodora, Ph.D., a principal investigator in SBRI's Viral Vaccines Program who recently joined SBRI from the University of Texas, Southwestern Medical Center, is senior author on one of three papers that collectively show CD4 T-cell depletion, a critical symptom of AIDS, is likely a part of a multifaceted scenario that triggers disease rather than the only cause.

   An international team of experts has published the first comprehensive review of evidence on pneumococcal conjugate vaccination for children with HIV infection. Now available in the online edition of the journal Lancet Infectious Diseases, the review shows that HIV increases the risk of pneumococcal infection by up to 40 fold, that the disease is usually due to serotypes in the PCV, and that the vaccine can protect HIV-infected infants.
