Researchers Develop Key Brake For Immune Cells In Petri Dish -- Hope For Easier Organ Transplantation?
Scientists from the Helmholtz Center for Infection Research in Braunschweig, Germany and the Medical School Hannover, Germany have succeeded in treating immune cells in a way that enables them to inhibit unwanted immune reactions such as organ rejection. Their results have now been published in the current issue of the scientific journal Journal of Cellular and Molecular Medicine.

Are Environmental Contaminants Endangering The Fertility Of Future Generations?
We know that the environment can have long-term effects on our health, but what about the health of those who aren"t born yet? A recent study looking at the birth weights of more than 5 million children born in Canada between 1981 and 2003 showed an increase in the frequency of genital malformations in male newborns and a decrease in male fertility.

Study Examines Gender Differences In Immune System's Response To HIV

New research showing that "a receptor molecule involved in the recognition of HIV-1 responds to the virus differently in women than in men," might "explain why HIV infection progresses faster to AIDS in women than in men with similar viral loads," the HealthDay/Greenville Daily Reflector reports. The study was conducted by researchers at the Ragon Institute of Massachusetts General Hospital, Massachusetts Institute of Technology and Harvard University and will be published in an upcoming issue of the journal Nature Medicine. Study authors also note that during the early stages of infection, women tend to have a stronger immune response to HIV than men, but then progress to AIDS more quickly. The different immune system response "then leads to differences in chronic T-cell activation, a known activator of disease progression, according to the researchers," the article states (7/13). Researcher Marcus Altfeld said the findings raise new questions about how sex hormones affect HIV in the body. "Focusing on immune activation separately from viral replication might give us new therapeutic approaches" to treating HIV, he added (AFP/Google News, 7/13).
