Phoenix rising: Scientists resuscitate a 5 million-year-old retrovirus
A team of scientists has reconstructed the DNA sequence of a 5-million-year-old retrovirus and shown that it is able to produce infectious particles. view more (2006-10-31)
Bushmeat poses threat of simian retrovirus transmission to humans (pp 911, 932)
Epidemiological research from central Africa in this week's issue of THE LANCET highlights how a new form of retrovirus - simian foamy virus (SFV) - can be transferred from primates to humans as a result of hunting for bush meat. Although the effect of simian foamy viruses on human health is not yet known, authors of the research state that a... view more... (2004-03-17)
New evidence of battle between humans and ancient virus
For millennia, humans and viruses have been locked in an evolutionary back-and-forth -- one changes to outsmart the other, prompting the second to change and outsmart the first. view more (2008-07-22)
Researchers find first evidence of virus in malignant prostate cells
In a finding with potentially major implications for identifying a viral cause of prostate cancer, researchers at the University of Utah and Columbia University medical schools have reported that a type of virus known to cause leukemia and sarcomas in animals has been found for the first time in malignant human prostate cancer cells. view more (2009-09-08)
Yamanaka eliminates viral vector in stem cell reprogramming
Shinya Yamanaka MD, PhD, of Kyoto University and the Gladstone Institute of Cardiovascular Disease (GICD) has taken another step forward in improving the possibilities for the practical application of induced pluripotent stem (iPS) cell technology. view more (2008-10-13)
Performing monkeys in Asia carry viruses that could jump species to humans
Some urban performing monkeys in Indonesia are carrying several retroviruses that are capable of infecting people, according to a new study led by University of Washington researchers. view more (2005-12-08)
New highly active agents against leishmaniasis
Parasitic diseases, especially leishmaniases and trypanosomiases, kill hundreds of thousands of people every year in the world, mainly in the countries of the South. The most severe form of leishmaniosis (kala-azar, the visceral form), induced by Leishmania donovani and L. infantum, affects about 500 000 people per year and proves fatal if no... view more...

'Virus chip' detects new virus in prostate tumors
UCSF and Cleveland Clinic scientists have discovered a new virus in human prostate tumors. The type of virus, closely related to viruses typically found in mice, has never been detected in humans. view more (2006-02-27)
New research strategy for understanding drug resistance in leukemia
UCSF researchers have developed a new approach to identify specific genes that influence how cancer cells respond to drugs and how they become resistant. This strategy, which involves producing diverse genetic mutations that result in leukemia and associating specific mutations with treatment outcomes, will enable researchers to better understand... view more...

New human retrovirus originated in mice
Howard Hughes Medical Institute researchers and their colleagues have discovered a new retrovirus in humans that is closely related to a cancer-causing virus found in mice. view more (2006-03-31)
Spread of endogenous retrovirus K is similar in the DNA of humans and rhesus monkeys
According to paleontologic and molecular studies, the chimpanzee (Pan troglodytes) is the closer relative to the humans (Homo sapiens) and that both lineages had a common ancestor at 5 to 7 million years ago. view more (2007-10-10)
Body's anti-HIV drug explained
Humans have a built-in weapon against HIV, but until recently no one knew how to unlock its potential. view more (2008-10-13)
HIV-1 : RECOMBINATION BETWEEN TWO STRAINSFROM WIDELY DISTANT GROUPS
Scientists have known for a long time that the AIDS virus is genotypically highly variable. Two main types of the virus exist: HIV-1 and HIV-2. HIV-1, the most widespread throughout the world, can be divided into three groups (M, N and O) each of which has different genetic characteristics. Within group M, which gathers together the most frequent... view more... (2000-03-09)
Recipe for cell reprogramming adds protein
A drug-like molecule called Wnt can be substituted for the cancer gene c-Myc, one of four genes added to adult cells to reprogram them to an embryonic-stem-cell-like state. view more (2008-08-07)
Imitating monkey's 'jumping genes' could lead to new treatments for HIV
UCL (University College London) scientists have taken a significant step in understanding how retroviruses such as HIV can move between species and the biological mechanisms behind the 'jumping genes' which make some monkeys immune. They will now use this knowledge to develop a gene therapy treatment for HIV/AIDS in humans. view more (2008-02-19)
Viruses can jump between primates and humans, researchers warn
Viruses that jump the species barrier between monkeys and humans can harm both people and animals, and we should take steps to reduce the risk of virus transmission. view more (2006-08-24)
Penn Study Identifies How Ebola Virus Avoids the Immune System
Researchers at the University of Pennsylvania School of Medicine have likely found one reason why the Ebola virus is such a powerful, deadly, and effective virus. Using a cell culture model for Ebola virus infection, they have discovered that the virus disables a cellular protein called tetherin that normally can block the spread of virus from... view more...

Primate virus jumps species barrier to humans for first time in Asia
Scientists have identified the first reported case in Asia of primate-to-human transmission of simian foamy virus (SFV), a retrovirus found in macaques and other primates that so far has not been shown to cause disease in humans. The transmission of the virus from a monkey to a human took place at a monkey temple in Bali, Indonesia, the... view more... (2005-07-14)
T vs. B: Re-engineered human T cells effectively target and kill cancerous B cells
Human white blood cells, engineered to recognize other malignant immune cells, could provide a novel therapy for patients with highly lethal B cell cancers such as acute lymphoblastic leukemia (ALL), according to researchers at Memorial Sloan-Kettering Cancer Center (MSKCC). view more (2007-09-18)
Mayo Clinic researchers invent 'hitchhiking' viruses as cancer drug delivery system
A Mayo Clinic research team has devised a new virus-based gene therapy delivery system to help fight cancer. Researchers say their findings will help overcome hurdles that have hindered gene therapy cancer treatments. view more (2005-09-19)
