University of Pittsburgh Schools of the Health Sciences The first direct proof of a long-suspected cause of multiple HIV-related health complications was recently obtained by a team led by the University of Pittsburgh Center for Vaccine Research (CVR). The finding supports complementary therapies to antiretroviral drugs to significantly slow HIV progression. The study, which will be published in the June issue of the Journal of Clinical Investigation and is available online, found that...

Scientists Testing AIDS Vaccine On Primates
2013-09-11 19:20:16

Brett Smith for redOrbit.com – Your Universe Online A promising new AIDS vaccine being developed at Oregon Health & Science University has demonstrated the capacity to effectively remove all traces of an AIDS-causing virus from non-human primates, according to a newly published report in the journal Nature. The vaccine is being tested on a primate form of HIV, called simian immunodeficiency virus (SIV), which causes AIDS in monkeys. After working further to refine the vaccine,...

Simian Foamy Viruses Readily Occur Between Humans And Macaques In Urban Bangladesh
2013-09-04 13:11:30

University of Washington Researchers hope to protect humans from another deadly outbreak like HIV Throughout Asia, humans and monkeys live side-by side in many urban areas. An international research team from the University of Washington, Fred Hutchinson Cancer Research Center and Jahangirnagar University has been examining transmission of a virus from monkeys to humans in Bangladesh, one of the world's most densely populated countries. The scientists have found that some people in...

HIV May Have Been Around Longer Than You Think

April Flowers for redOrbit.com - Your Universe Online A new study, led by Alfred Roca of the College of Agricultural, Consumer and Environmental Sciences (ACES) at the University of Illinois, reveals that human immunodeficiency virus (HIV) may have affected humans for much longer than is currently believed. Roca, an assistant professor, believes the genomes of an isolates West African population provides important clues about the evolution of the HIV virus. HIV is thought to have...

The findings of a new study in monkeys may help clarify why some people infected with HIV are better able to control the virus. They also may pinpoint a target for treatment during early HIV infection aimed at increasing the supply of certain immune cells in the gut, which the study shows could be an important factor in limiting HIV growth in cells throughout the body. The study was led by researchers at the University of California, San Francisco (UCSF) and included Kristina Abel, PhD, an...

After being infected with SIV, rhesus macaques that had more of a certain type of immune cell in their gut than others had much lower levels of the virus in their blood, and for 6 months after infection were better able to control the virus After being infected with simian immunodeficiency virus (SIV) in a laboratory study, rhesus macaques that had more of a certain type of immune cell in their gut than others had much lower levels of the virus in their blood, and for six months after...

An Atlanta research collaboration may be one step closer to finding a vaccine that will provide long-lasting protection against repeated exposures to human immunodeficiency virus (HIV). Scientists at Emory University and GeoVax Labs, Inc. developed a vaccine that has protected nonhuman primates against multiple exposures to simian immunodeficiency virus (SIV) given in three clusters over more than three years. SIV is the nonhuman primate version of HIV. Harriet L. Robinson, PhD, chief...

The Consequences Of Non-intervention For Infectious Disease In African Great Apes
2012-02-07 05:00:12

Infectious disease has joined poaching and habitat loss as a major threat to the survival of African great apes as they have become restricted to ever-smaller populations. Despite the work of dedicated conservationists, efforts to save our closest living relatives from ecological extinction are largely failing, and new scientific approaches are necessary to analyze major threats and find innovative solutions. In response to this crisis, researchers at UC Santa Barbara's National Center for...

Using a combination of evolutionary biology and virology, scientists at Fred Hutchinson Cancer Research Center have traced the birth of the ability of some HIV-related viruses to defeat a newly discovered cellular-defense system in primates. The research, led by Michael Emerman, Ph.D., a member of the Hutchinson Center's Human Biology and Basic Sciences Division, and Harmit Malik, Ph.D., a member of the Center's Basic Sciences Division, was published online Jan. 26 ahead of the Feb. 16...

Experimental Potential HIV Vaccine Proves Promising In Monkeys
2012-01-05 10:02:23

An experimental vaccine tested in rhesus monkeys helped protect them from getting infected with Simian Immunodeficiency Virus (SIV) -- the primate version of HIV and AIDS -- and appears to make the disease more manageable in those who aren´t protected, researchers reported on Wednesday. The vaccine reduced the risk of infection by 80 percent among the monkeys exposed to SIV, while monkeys that became infected had lower amounts of the virus in their blood, the research team reported in...

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...
