A U.S. research team says it may have broken the stubborn impasse that has frustrated the invention of an effective human immunodeficiency virus vaccine. The scientists from the Children's Hospital of Philadelphia and the Nationwide Children's Hospital in Columbus, Ohio, said they used an approach that bypasses the usual path followed by vaccine developers. By using gene transfer technology that produces molecules that block infection, the scientists said they successfully protected rhesus...

The ancestors of the simian immunodeficiency viruses (SIVs) that jumped from chimpanzees and monkeys, and ignited the HIV/AIDS pandemic in humans, have been dated to just a few centuries ago. These ages are substantially younger than previous estimates, according to a new study from The University of Arizona in Tucson, published May 1st in the open-access journal PLoS Computational Biology. SIV has crossed over from chimpanzees and sooty mangabeys to humans at least eleven times, giving rise...

A potential treatment for HIV may one day help people who are not responding to Anti-Retroviral Therapy, suggests new research published tomorrow in The Journal of Immunology. Scientists looking at monkeys with the simian form of HIV were able to reduce the virus levels in the blood to undetectable levels, by treating the monkeys with a molecule called D-1mT alongside Anti-Retroviral Therapy (ART).Simian Immunodeficiency Virus (SIV) is very similar to Human Immunodeficiency Virus (HIV) and it...

The relentless search for a vaginal gel to avert the AIDS virus got some good news on Wednesday, when scientists reported that a low-cost, common compound protected monkeys from a lethal variation of HIV. However, the scientists caution that plenty of work lies ahead before the microbicide can be verified as safe and effective for humans. Nevertheless, the outcome was embraced as an encouraging sign. A cream that blocks or kills the human immunodeficiency virus (HIV) is a large part of...

BioReliance announces the introduction of its new protein array platform that offers greater sensitivity, reduced testing time and reliable results. The platform, brand-named ReliArray(TM), can simultaneously screen for four non-human pathogens in animal serum. "It is essential to researchers that they can depend on the results of serological screenings. These tests ensure that their research animals are healthy and will keep their research results uncompromised. Until ReliArray was...

U.S. scientists say a paradoxical discovery might help explain why some species can live with immunodeficiency viruses that never progress to AIDS. A team of scientists from Yerkes National Primate Research Center and the Emory Vaccine Center report the simian immunodeficiency virus -- the AIDS virus found in apes and monkeys -- does not lead to a strong immune response in sooty mangabeys, one of numerous African primate species that harbor SIVs, but remain healthy despite their infection....

U.S. scientists say they have found evidence that a component of the cell walls of intestinal bacteria help the human immunodeficiency virus enter the brain. The Albert Einstein College of Medicine researchers said in up to 20 percent of people infected with HIV, the virus manages to escape from the bloodstream and cross into the brain, resulting in HIV-associated dementia and other cognitive disorders. The Yeshiva University scientists said their findings might lead to the development of...

Energex Systems, Inc. announced today that it has been granted approval from the Federal Food and Drug Administration (FDA) to utilize its experimental HemoModulation(TM) therapy in a clinical trial of HIV infected patients. The purpose of the study will be to demonstrate safety and monitor viral load changes in patients who are not yet eligible for antiviral drug therapy. HIV is a retrovirus that attacks the immune system, destroying or impairing its function. As the disease progresses,...

Sooty Mangabey, Cercocebus atys
2012-06-28 20:49:18

The sooty mangabey (Cercocebus atys) is an Old World Monkey that can be found throughout the area stretching from Senegal to eastern Ghana. Its other common names include the white-naped mangabey, the white-crowned mangabey, and the white-collared mangabey, which causes some confusion with the collared mangabey. There are currently two recognized subspecies of this mangabey, although they can be considered distinct species. The sooty mangabey resides in forests within its range, preferring...

Simian immunodeficiency virus (SIV), also known as African Green Monkey virus, is a retrovirus able to infect at least 33 species of African primates. SIV has been present in monkeys and apes for at least 32,000 years, probably longer. Strains from two of these primate species have crossed the barriers into humans resulting in HIV-2 and HIV-1. Contraction involves contact with the blood of chimps that are often hunted for bushmeat in Africa. SIV infections appear in many cases to be...
