Scientists have mapped the spread of the HIV virus around the globe after it reached the United States in the early 1970s. Their study finds that HIV travelled from the US to Western Europe on a number of occasions, whereas Central and Eastern Europe remained isolated for the most part of the early epidemic. The study describes the global spread of HIV-1 subtype B, but not of other subtypes.

HIV spreads much more rapidly through the body after initial infection than previously believed, apparently causing immediate immune reactions that enable its replication. Publishing their findings in the journal Cell, researchers vaginally exposed 44 rhesus monkeys to SIV, HIV’s simian cousin, and analyzed the animals during the first few days post-infection.

Across our bodies colonies of microorganisms flourish. The largest microbiome colony lives in our gastrointestinal tract—our gut—and in healthy people, helps us do things like digest carbohydrates, produce vitamins and prevent harmful pathogens from flourishing. When there’s a disruption to our gut microbiome, problems can arise. Now, researchers are investigating how HIV and the microbiome are linked.

In addition to possibly being a component of the HIV reservoir, fat tissue may also be a source of harmful chronic inflammation among those living with the virus. Publishing their findings in PLOS Pathogens, researchers studied adipose (fat) tissue in both macaque monkeys infected with SIV, HIV’s simian cousin, as well as HIV-positive humans who underwent elective abdominal surgery.

HIV-1 infection with multiple founder variants points to poorer clinical outcomes than infection with a single variant, according to a paper published today in Nature Medicine. In the study researchers analyzed large sample sets from two important HIV vaccine efficacy trials -- the Step HIV vaccine clinical trial (HVTN 502) and RV144, the landmark vaccine clinical trial conducted in Thailand -- to evaluate whether genetic characteristics of the founder viral populations could influence markers of clinical outcomes.

A study published on Aug. 20th in PLOS Pathogens of antiviral gene sequences in African monkeys suggests that lentiviruses closely related to HIV have infected primates in Africa as far back as 16 million years.

When Peter Parham’s postdoc first showed him data suggesting a gene in some wild chimpanzees infected with the AIDS virus closely resembled one that protects humans from HIV, he was skeptical.

As HIV investigators work to control and eradicate the virus worldwide, certain myths or misconceptions about the disease have been embraced, whereas other concepts with merit have been left relatively unexplored, argues American HIV/AIDS researcher Jay Levy, M.D., in a Trends in Molecular Medicine commentary. He calls on fellow researchers to continue questioning and not to lose sight of alternative strategies that could ultimately lead to a sustainable, long-term solution to HIV infection.
