Brown University scientists say they've genetically modified some of the 'friendly bacteria' found in yogurt to release a drug that blocks HIV infection.
Although the bacteria have only been tested in the lab, the scientists are optimistic their technique could provide a cheaper and more effective way of delivering drugs to fight the spread of AIDS, nature.com reported.
The researchers, led by Bharat Ramratnam, an HIV specialist at the university, altered the genetic makeup of L. lactis, so it generates cyanovirin, a drug that has prevented HIV infection in monkeys and human cells and which will be involved in human trials next year.
The researchers report their findings in the Journal of Acquired Immune Deficiency Syndrome.

Scientists identify gene that may make humans more vulnerable to pulmonary tuberculosis
Researchers from the Genome Institute of Singapore (GIS) and its collaborators have now identified for the first time a new gene that may confer susceptibility to pulmonary tuberculosis. Their findings, published October 10 in the open access journal
PLoS Genetics, reported that a gene named Toll-like receptor 8 (TLR8), previously shown only to recognize some factors from viruses such as the human immunodeficiency virus (HIV), has a probable role in human susceptibility to
Mycobacterium tuberculosis infections. The results from the study also found that males are more susceptible than females.

What HIV needs: Identification of human factors may yield novel therapeutic targets for HIV
The Salk Institute for Biological Studies and Burnham Institute for Medical Research today announced 295 host cell factors that are involved in human immunodeficiency virus (HIV) infection. The study, published in the Oct. 3 issue of
Cell, could lead to the development of a new class of HIV therapeutics aimed at disrupting the human-HIV interactions that lead to viral infection.
HIV drug maraviroc effective for drug-resistant patients
As many as one quarter of HIV patients have drug resistance, limiting their treatment options and raising their risk for AIDS and death. Now, maraviroc, the first of a new class of HIV drugs called CCR5 receptor antagonists, has been shown to be effective over 48 weeks for drug-resistant patients with R5 HIV-1, a variation of the virus found in more than half of HIV-infected patients.
Existing anti-obesity drugs may be effective against flu, hepatitis and HIV
Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection, according to a study published today in the journal
Nature Biotechnology.
Scientists unmask key HIV protein, open door for more powerful AIDS drugs
University of Michigan scientists have provided the most detailed picture yet of a key HIV accessory protein that foils the body's normal immune response. Based on the findings, which appear online in the journal
PLoS Pathogens, the team is searching for new drugs that may someday allow infected people to be cured and no longer need today's AIDS drugs for a lifetime.
Why some primates, but not humans, can live with immunodeficiency viruses and not progress to AIDS
Key differences in immune system signaling and the production of specific immune regulatory molecules may explain why some primates are able to live with an immunodeficiency virus infection without progressing to AIDS-like illness, unlike other primate species, including rhesus macaques and humans, that succumb to disease.
