Are HIV Non-Progressors Really Very Slow Progressors?

HIV positive people traditionally classified as long-term non-progressors or viral controllers may in fact progress slowly over time, according to research reported in the February 20, 2012, edition of the open-access journal PLoS ONE. These findings suggest that so-called non-progressors may in fact benefit from antiretroviral therapy and could provide clues to aid in development of immune-based therapies.

Immune cells use 'starvation tactics' on HIV

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.

Immediate ART during Early HIV Infection May Delay Disease Progression

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 Announces HIV-AIDS Research Discovery

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).

'Pep talk' can revive immune cells exhausted by chronic viral infection

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion. Yet exhausted immune cells can be revived after the introduction of fresh cells that act like coaches giving a pep talk, researchers at Emory Vaccine Center have found.
