Lee Rannals for redOrbit.com - Your Universe Online An AIDS Conference in Washington D.C. on Tuesday gave hope in the search for finding a cure for the disease that caused nearly 30 million deaths since the 1980s. With around 34 million people around the world living with HIV, experts say a cure is more crucial than ever before, because the rate of infections is outpacing the world's ability to medicate people. "For every person who starts antiretroviral therapy, two new individuals...

Timothy Ray Brown, an HIV-positive American, known as "the Berlin patient," has become an icon for the potential end of a disease that has claimed the lives of countless millions, and has also become a sign of hope for scientists who are trying to end the AIDS pandemic.Remarkable scientific advances since HIV was first discovered 30 years ago this week mean the virus is no longer a death sentence. Thanks to tests that detect HIV early on, new drugs that have been developed that can control...

(Ivanhoe Newswire) -- In the years since the AIDS epidemic began, it has become clear that there is substantial variation in the way that individuals respond to HIV infection. Although most progress quickly from initial infection to immunodeficiency, a small subset survive for long periods without developing symptoms. These patients, dubbed elite controllers, display undetectable levels of viral replication, but the mechanism that explains how their immune systems effectively control the...

Elevated p21 expression blocks key steps in viral life cycle Elevated levels of p21, a protein best known as a cancer fighter, may be involved in the ability of a few individuals to control HIV infection with their immune system alone. In a paper in the April edition of the Journal of Clinical Investigation, researchers from the Massachusetts General Hospital (MGH) Infectious Disease Division and the Ragon Institute of MGH, MIT and Harvard report that CD4 T cells from HIV controllers, while...

Although untreated HIV infection eventually results in immunodeficiency (AIDS), a small group of people infected with the virus, called elite suppressors (0.5 percent of all HIV-infected individuals), are naturally able to control infection in the absence of antiretroviral therapy, or HAART. Elite suppressors and HIV- infected individuals treated with HAART have similar levels of virus in the blood stream. However, levels of HIV integrated into immune cells are much lower in elite suppressors...

TUCSON, Ariz., June 2 /PRNewswire-USNewswire/ -- The idea of early detection and cure is appealing. But if the test is unreliable, and the treatment itself harmful, universal testing can do more harm than good. The availability of highly active antiretroviral treatment (HAART) for AIDS is leading to calls for universal testing for human immunodeficiency virus (HIV), which can progress to AIDS, and for early use of this expensive drug cocktail. While HIV testing is said to be highly...

Scientists at Duke University Medical Center have identified a set of naturally occurring antibodies that can block one of the key ways the AIDS virus gains entry into certain blood cells. They say the discovery, published online in the Journal of Experimental Medicine, expands traditional notions about how the immune system fights HIV and offers a potential new strategy for HIV vaccine design. Researchers have been puzzled and frustrated for years by antibody responses to HIV. In most...

HIV/AIDS remains one of the world's most significant public health challenges, particularly in developing countries. The Human Immunodeficiency Virus (HIV-1), the variant responsible for the pandemic, has the ability to infect different cell types such as T cells, macrophages and dendritic cells (DC). These latter cells are crucial in the defense against infectious agents and play a major role in viral pathogenesis. The present study, led by researchers from Hospital Clinic de...
