CROI 2018: PCSK9 levels raised in asymptomatic HIV patients

Levels of proprotein convertase sutilisin/kexin 9 (PCSK9), the enzyme encoded on chromosome 1, are elevated in asymptomatic patients with HIV — possibly giving researchers another resource by which to diagnose…

Tweak to broadly neutralizing HIV antibody makes it last longer

Researchers are trying to harness the power of certain antibodies as long-acting injectable forms of HIV treatment or PrEP. Researchers have found that a slight modification to the broadly neutralizing…

Cannabis associated with immune cell frequency reduction in ART-treated HIV patients

A recent study found that cannabis use is associated with a potentially beneficial reduction in systemic inflammation and immune activation in the context of antiretroviral therapy (ART)-treated HIV-infected individuals. Findings…

Infection site affects how a virus spreads through the body

Different routes of sexual transmission affect the immune system’s response to a virus, shows new study San Francisco, CA—A person is more likely to get infected by HIV through anal…

Patent related to strain-independent amplification of HIV nucleic acid sequences DURHAM, N.C., Feb. 15, 2018 -- Argos Therapeutics Inc. (NASDAQ:ARGS), an immuno-oncology company focused on the development and commercialization of…

Promising drug target could restore immune system’s ability to fight HIV

Scientists in NCI’s Center for Cancer Research have identified a new target for drugs that could help people who are HIV-positive eliminate recalcitrant pools of the virus. The research findings…

How viruses disarm the immune system

Discovery of molecular mechanism could point toward new targets for treating patients How do viruses that cause chronic infections, such as HIV or hepatitis C virus, manage to outsmart their…

Recruiting natural killer cells to target HIV persistence

An important goal in HIV cure research is the identification of immune responses that might be induced or enhanced to promote clearance of virus-infected cells. The main focus of this…

Novel genomic tools provide new insight into human immune system

When the body is under attack from pathogens, the immune system marshals a diverse collection of immune cells to work together in a tightly orchestrated process and defend the host…

Antibodies show effectiveness for HIV prevention and promise for treatment and cure

The ability of HIV to mutate has been a major challenge to vaccine development. As the body produces antibodies to target the outer HIV envelope protein, this protein changes, thwarting…
