Bread Mold May Unlock Secret To Eliminating Disease-causing Genes
Scientist have examined a new mechanism in the reproductive cycle of a certain species of mold. This mechanism protects the organism from genetic abnormalities by "silencing" unmatched genes during meiosis (sexual reproduction). The finding could have implications for higher organisms and may lead to precise "targeting" of unwanted genes, such as those from the HIV virus.

New Study Shows How Genes Control Blood Proteins Important To Health
A new study shows how genes control levels of many blood proteins implicated in disease. Newly published determine how many of the key proteins within our blood are under genetic control, showing that diet and lifestyle are not the only factors influencing its makeup.

Major Shift In HIV Prevention Priorities Needed, Analysts Urge
According to a new policy analysis the most common HIV prevention strategies -- condom promotion, HIV testing, treatment of other sexually transmitted infections, vaccine and microbicide research, and abstinence -- are having a limited impact on the predominantly heterosexual epidemics found in Africa.

Molecular Espionage Shows A Single HIV Enzyme's Many Tasks
Using ingenious molecular espionage, scientists have found how a single key enzyme, seemingly the Swiss army knife in HIV's toolbox, differentiates and dynamically binds both DNA and RNA as part of the virus' fierce attack on host cells.

Do Antidepressants Enhance Immune Function?
Infection with human immunodeficiency virus, which leads to acquired immunodeficiency syndrome, is an epidemic of global concern. The functioning of natural killer (NK) cells, which are a major element of the innate immunity system and are involved in the body's first line of defense against infections such as HIV, is decreased in both HIV and depression. A group of researchers who have previously found that stress and depression impair NK cell function and accelerate the course of HIV/AIDS are now publishing a new report in Biological Psychiatry.
