Scientists have solved a mystery that has long baffled HIV researchers: How does HIV manage to enter the nucleus of immune system cells? The discovery could lead to effective new drugs to treat HIV/AIDS.

Adults and children with HIV who start antiretroviral therapy (ART) as early as possible reduce their risk of developing serious HIV-related infections, according to new findings published in the journal Clinical Infectious Diseases on 15 June 2016.

Infection with HIV may be associated with accelerated cellular aging, according to a new study in which researchers analyzed DNA methylation patterns of men with HIV infection. The study provides a possible explanation for why people with HIV who take antiretroviral medications often develop age-related conditions such as cardiovascular disease, hypertension, bone fractures, and renal failure years earlier than those who are uninfected.

Thanks to combination antiretroviral therapy, many people with HIV can be expected to live decades after being infected. Yet doctors have observed that these patients often show signs of premature aging. Now a study published April 21 in Molecular Cell has applied a highly accurate biomarker to measure just how much HIV infection ages people at the biological level -- an average of almost 5 years.

Scientists have identified a human (host) protein that weakens the immune response to HIV and other viruses. The findings have important implications for improving HIV antiviral therapies, creating effective viral vaccines, and advance a new approach to treat cancer.

A study published in PLOS Pathogens suggests that it is not a general weakening of the immune system by HIV that initially leads to loss of Mtb control, but rather that HIV is associated with a failure to prevent harmful immune responses. As HIV disease progresses, the weakening immune system's focus on antiviral responses leaves it largely defenseless against the Mtb pathogen.

HIV infection also can lead to diseases affecting the intestines, with increased gastrointestinal (GI) inflammation, diarrhea and problems with nutrient absorption. The role of gut microbes in such issues is not completely understood, but now, in two studies led by researchers at Washington University School of Medicine in St. Louis, scientists have identified intestinal bacteria and viruses as possible sources of such inflammation and disease.

HIV-1 infection with multiple founder variants points to poorer clinical outcomes than infection with a single variant, according to a paper published today in Nature Medicine. In the study researchers analyzed large sample sets from two important HIV vaccine efficacy trials -- the Step HIV vaccine clinical trial (HVTN 502) and RV144, the landmark vaccine clinical trial conducted in Thailand -- to evaluate whether genetic characteristics of the founder viral populations could influence markers of clinical outcomes.

Inflammation is the generic term for the body’s response to injury. During injury, the immune system—our body’s defense system—activates a complicated network of cells and chemical signals. Acute inflammation, immune activation that’s rapid and self-limited, is essential for healing. But chronic inflammation, immune activation that continues even after the initial injury is gone, is problematic. Chronic inflammation is like a volume control knob on a stereo being stuck—with the volume turned all the way up.
