Studies have shown that about 10 per cent of men infected with human immunodeficiency virus (HIV) have an elevated resting energy expenditure (REE). Now a study has shown that REE is also higher in women with HIV, even when they are on HIV treatment.

Human cells have an intrinsic capacity to destroy HIV. However, the virus has evolved to contain a gene that blocks this ability. When this gene is removed from the virus, the innate human immune system destroys HIV by mutating it to the point where it can no longer survive.

New research has disocvered how the HIV virus targets memory T-cells or "veterans" instead of naive "virgin" T-cells. This could potentially change how drugs are used to halt the virus. This research finds that HIV exploits the fact that memory T-cells are more mobile; it uses the cytoskeleton, the internal structure of the cell, as a "conveyor belt" to carry it deep within the cell and to the nucleus. The researchers are now looking at whether drugs that reduce cancer cell motility could reduce the "attractiveness" of T-memory cells to HIV.

The cytomegalovirus (CMV) is a member of the herpesvirus family. Although most people carry CMV for life, it hardly ever makes them sick. Researchers from the Helmholtz Centre for Infection Research and from the USA have now unveiled long term consequences of the on-going presence of CMV: Later in life, more and more cells of the immune system concentrate on CMV, and as a result, the response against other viruses is weakened. These research results help to explain why the elderly are often more prone to infectious diseases than young people.
The viral immunologist Professor Luka Cicin-Sain, head of the junior research group "Immune Aging and Chronic Infections" at the HZI in Braunschweig, Germany, and his colleagues have now published their discovery in the open access journal PLoS Pathogens. In the article, they describe that even months after infection with CMV, mice still show weaker responses against other viruses such as the flu 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 infection were better able to control the virus.

Scientists have identified a new HIV-suppressing protein in the blood of people infected with the virus. In laboratory studies, the protein, called CXCL4 or PF-4, binds to HIV such that it cannot attach to or enter a human cell.

A new understanding of the initial interactions of human immunodeficiency virus type 1 (HIV-1) and dendritic cells is described by Boston University School of Medicine (BUSM) researchers in a study currently featured in the Proceedings of the National Academy of Sciences (PNAS).

Scientists have shown how some cells in the body can repel attacks from HIV by starving the virus of the building blocks of life. Viruses cannot replicate on their own; they must hijack other other cells and turn them into virus production factories.

People who started combination antiretroviral therapy (ART) within 6
months of HIV infection were less likely to experience large CD4 cell
decreases or AIDS-related illnesses during follow-up, although viral
load set point could not be evaluated, researchers reported.

Aethlon Medical, the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that researchers have discovered that the Aethlon Hemopurifier® is able to capture particles known as Nef protein exosomes, which contribute to the progression of human immunodeficiency virus (HIV) infection to acquired immunodeficiency syndrome (AIDS).
