An increase in the release of monocytes from bone marrow into the bloodstream predicts how rapidly AIDS develops in monkeys and the magnitude of monocyte turnover correlates with the severity of brain disease in AIDS, Boston College researchers report in the current edition of the online journal PLoS Pathogens. The researchers report the first observation within AIDS of a marker in blood or plasma exclusive to monocytes, which underscores the relationship between innate immune response and...

How the Vpu protein of HIV-1 interferes with the antiviral activity of Tetherin and contributes to the spread of HIV-1 in humans The discovery by Dr. Ó°ric A. Cohen's team at the Institut de recherches cliniques de Montr©al, could potentially lead to the development of new strategies to combat the human immunodeficiency virus (HIV-1), the causal agent of acquired immunodeficiency syndrome (AIDS). In their article published in the open-access journal PLoS...

ATLANTA, Feb. 18 /PRNewswire-FirstCall/ -- GeoVax Labs, Inc. (OTC Bulletin Board: GOVX) (the "Company"), an Atlanta-based, biopharmaceutical company developing vaccines for diseases caused by HIV-1 (Human Immunodeficiency Virus), today announced that it presented the results of a preclinical study on a prototype HIV/AIDS vaccine at the Conference on Retroviruses and Opportunistic Infections (CROI) in San Francisco. The oral presentation, "Preclinical Studies on DNA/MVA Vaccines:...

U.S. researchers reported on Sunday that an HIV genetic stowaway that may have come from a related cat virus could help the AIDS virus transmit and replicate in people, Reuters reported. Experts said the finding has implications for designing new drugs or a vaccine against the fatal and incurable virus. They said it might also shed light on how other viruses, such as swine flu, spread from animals to people. Additionally, the recent discoveries could help explain how an ancient virus came to...

SIV is a virus related to HIV that can infect monkeys. In some strains of monkey (which are known as natural hosts) SIV does not cause disease, whereas it does in others (which are known as susceptible hosts). It is hoped that understanding why SIV does not cause disease in natural hosts will provide insight into how to control HIV infection of humans. Two independent research teams, one led by Michaela C. Mller-Trutwin, and the other led by Guido Silvestri, Ashley Haase, and David Kelvin,...

Researchers at the Yerkes National Primate Research Center, Emory University, believe conventional vaccine strategies should not be the only avenue explored in the development of an effective AIDS vaccine. Based on studying simian immunodeficiency viruses (SIVs) in African nonhuman primates, they propose an additional new approach to the AIDS vaccine research agenda in a commentary featured in the August issue of Nature Medicine. Their recommendations outline specific research priorities and...

Researchers found a gorilla strain of HIV in a Cameroonian woman, they reported in Paris Sunday. This demonstrates that HIV evolution is an ongoing process, Dr. David Robertson, an AIDS researcher and frequent contributor to Nature Medicine, told the magazine. The HIV-1 strain, which is the main source of human infections, with 33 million cases worldwide, came from a chimpanzee virus. It was discovered in the 1980s, but is believed to have jumped to humans who came into contact with infected...

Wild chimpanzees infected with Simian Immunodeficiency Viruses can contract AIDS-like symptoms and die, U.S. researchers said Wednesday. SIV has many forms and was thought to be harmless to apes, researchers from the University of Illinois who participated in the global study said in a news release. SIV is the precursor virus for AIDS and HIV-1, which first entered human populations after transmission from chimpanzees. Chimpanzees and humans are very similar genetically, so perhaps we should...

It appears that an AIDS-like disease that was considered to be harmless to chimpanzees can infect the apes and kill them as well, researchers reported on Wednesday. The simian immunodeficiency virus (SIV) is considered to be a precursor virus to the AIDS virus, HIV-1. SIV comes in various forms, most of which are capable of infecting a variety of monkey species in Africa. Scientists had previously considered SIV was unable to infect and kill apes in similar fashion to HIV in humans. However,...

Researchers at Yerkes National Primate Research Center, Emory University, contributed key comparative data for a landmark study showing African wild chimpanzees infected with simian immunodeficiency virus (SIV), an HIV-1-like virus, die prematurely and develop hallmarks of HIV-1 infection and AIDS.This surprising discovery by scientists at the University of Alabama at Birmingham (UAB), and reported in the July 23 issue of Nature, alters the current view of AIDS virus infections in African...

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...
