Association of herpesvirus with lung disorder questioned

Contrary to the results of a recent U.S. study, investigators in Japan found no association between a herpesvirus infection and a potentially life-threatening form of high blood pressure, as reported in the March 1 issue of The Journal of Infectious Diseases, now available online. The researchers reported that they were not able to detect human herpesvirus 8 (HHV-8), also known as the Kap...

Topical treatment shown to inhibit HIV and herpes simplex virus infection

Mount Sinai School of Medicine researchers demonstrated that a gel applied in the vagina provides protection from both the human immunodeficiency virus (HIV) and the herpes simplex Virus. The study, presented at the 12th Conference on Retroviruses and Opportunistic Infections, is the first to show that a gel can retain anti-viral activity within the human vagina. The study, which was fund...

Elusive HIV shape change revealed; Key clue to how virus infects cells

Structural biologists at Children's Hospital Boston and Harvard Medical School have shown how a key part of the human immunodeficiency virus (HIV) changes shape, triggering other changes that allow the AIDS virus to enter and infect cells. Their findings, published in the Feb. 24 issue of the journal Nature, offer clues that will help guide vaccine and treatment approaches. Researchers led...

Scientists Replicate Hepatitis C Virus in Laboratory

For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV. Scientists at the National Institute of Diabetes...

Virus classification

can be classified in several ways, such as by their geometry, by whether they have envelopes, by the identity of the host organism they can infect, by mode of transmission, or by the type of disease they cause. The most useful classification is probably by the type of nucleic acid the virus contains and its mode of expression. Th...
