Scientists develop a new HIV microbicide -- and a way to mass produce it in plants
New research in the FASEB Journal describes a one-two punch in the battle against HIV
In what could be a major pharmaceutical breakthrough, research published online in The FASEB Journal describes how scientists from St George's, University of London have devised a one-two punch to stop HIV. First the report describes a new protein that can kill the virus when used as a microbicide. Then the report shows how it might be possible to manufacture this protein in quantities large enough to make it affordable for people in developing countries.
Marijuana rivals mainstream drugs for HIV/AIDS symptoms
Those in the United States living with HIV/AIDS are more likely to use marijuana than those in Kenya, South Africa or Puerto Rica to alleviate their symptoms, according to a new study published in Clinical Nursing Research, published by SAGE.

Extensive HIV-1 Intra-Host Recombination Is Common in Tissues with Abnormal Histopathology
There is evidence that immune-activated macrophages infected with the Human Immunodeficiency Virus (HIV) are associated with tissue damage and serve as a long-lived viral reservoir during therapy. In this study, we analyzed 780 HIV genetic sequences generated from 53 tissues displaying normal and abnormal histopathology. We found up to 50% of the sequences from abnormal lymphoid and macrophage rich non-lymphoid tissues were intra-host viral recombinants. The presence of extensive recombination, especially in non-lymphoid tissues, implies that HIV-1 infected macrophages may significantly contribute to the generation of elusive viral genotypes in vivo. Because recombination has been implicated in immune evasion, the acquisition of drug-resistance mutations, and alterations of viral co-receptor usage, any attempt towards the successful eradication of HIV-1 requires therapeutic approaches targeting tissue macrophages.
