Breakthrough findings point to targets for Ebola virus drugs and vaccines

Described in the July 10, 2008 issue of the journal Nature, the research reveals the shape of the Ebola virus spike protein, which is necessary for viral entry into human cells, bound to an immune system antibody acting to neutralize the virus. The structure provides a major step forward in understanding how the deadly virus works, and may be useful in the development of potential Ebola virus vaccines, or treatments for those infected.

Enzyme may explain how hepatitis C infection causes fatty liver

A key enzyme may explain how hepatitis C infection causes fatty liver - a buildup of excess fat in the liver, which can lead to life-threatening diseases such as cirrhosis and liver cancer, report University of Pittsburgh Graduate School of Public Health and School of Medicine researchers.

Researchers to compare common ARV as a pill and vaginal gel in unique HIV prevention study

In battle with an epidemic that has outpaced nearly all efforts to contain it, researchers are turning to strategies centered on the same antiretroviral (ARV) drugs that have been used successfully to treat HIV in hopes they will be as effective a stronghold for preventing the virus.

The paradox of anti-HIV vaginal microbicides

With no HIV/AIDS vaccine or cure in sight, vaginal microbicides now in clinical trials are one of the most promising weapons that will protect women against HIV infection. Yet these microbicides could be of more benefit to men than to women, according to a new study co-authored by the University of New South Wales' National Centre in HIV Epidemiology and Clinical Research (NCHECR) and UCLA.
