Scientists identify rare, paradoxical response to antiretroviral therapy

Antiretroviral therapy is usually very effective at suppressing HIV in the body, allowing a person's immune system to recover by preventing the virus from destroying CD4+ T cells.

Breakthrough antibody treatment suppresses HIV without antivirals

A new research paper describes how an antibody that prevents HIV binding to human immune cells was shown to be able to suppress levels of HIV for up to four months.

Sexual behavior could affect gut microbiome and immune system

A person's sexual behavior could affect their microbiome and immune system, potentially elevating their risk of HIV infection, according to a new study from researchers at the University of Colorado Anschutz Medical Campus.

Study finds no major epigenetic differences between space astronaut and his earthbound twin brother

In a landmark study, a group of U.S. scientists from Johns Hopkins, Stanford University and other institutions has found no long-lasting, major differences between the epigenomes of astronaut Scott Kelly, who spent a year in space aboard the International Space Station, and his twin brother, Mark, who remained on Earth.

Gut microbiome may drive HIV transmission risk in high-risk men

Gut microbes from high HIV-risk men who have sex with men drive immune activation in mice and HIV infection in cells, according to a study published April 4 in the open-access journal PLOS Pathogens by Brent Palmer and Catherine Lozupone of the University of Colorado Anschutz, and colleagues.

Common food preservative may influence effectiveness of flu vaccines

Michigan State University scientists have linked a common food preservative to an altered immune response that possibly hinders flu vaccines.

ETH researchers take major step towards personalized cancer immunotherapy

Cells belonging to the body's own immune system can help fight tumours. For several years now, this has allowed oncologists to use medications known as checkpoint inhibitors to encourage T cells to eliminate tumor cells.

World’s first HIV-to-HIV kidney transplant with living donor succeeds

The world's first kidney transplant from a living HIV-positive donor to another HIV-positive person was successfully performed Monday by doctors at a Johns Hopkins University hospital.

Exposure to HIV virus, antiretroviral therapy before birth linked to obesity and asthma-like symptoms

Teens and young adults who were exposed to HIV and antiretroviral therapy before birth but are HIV-negative themselves are at increased risk of obesity and asthma-like symptoms, according to research to be presented Saturday, March 23 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

Study offers new evidence that narcolepsy is an autoimmune condition

In a study of narcolepsy patients, researchers at the University of Copenhagen have made an important discovery that could help pave the way for improved treatment of the chronic condition.

HIV patients diagnosed with tuberculosis more likely to die within 10 years, study finds

Among people with HIV in Latin America, those diagnosed with tuberculosis at an initial clinic visit were about twice as likely to die within 10 years as people not initially diagnosed with TB, according to findings from a large observational study.

Study reveals how helper T cells support memory cells to function optimally

The immune system's killer T cells are crucial in fighting viral infections. A fraction of them, called 'memory cells', live on once infection is controlled in order to fight re-infection by the same virus. They are of great interest as the basis of T cell-based vaccination and immunotherapies.

Anti-cancer immunotherapy could be used to fight HIV

Researchers at the University of Montreal Hospital Research Centre have shown that immunotherapy treatments against cancer could reduce the amount of virus that persists in people on triple therapy.

Immune checkpoint molecule protects against future development of cancer

A research team at the University of Louisville has discovered that an immune checkpoint molecule they developed for cancer immunotherapy, also protects against future development of multiple types of cancer when administered by itself.

Study: CD4+ T cells could be important mediators of protection against Zika virus

Immune cells called CD4+ T cells could be important mediators of protection against the Zika virus, according to a study published January 24 in the open-access journal PLOS Pathogens by Sujan Shresta of the La Jolla Institute for Allergy and Immunology, and colleagues.

New resource-based approach to improve HIV care in low- and middle-income countries

A practical resource-based public health approach for the rapid initiation of antiretroviral therapy in HIV-infected individuals living in low- and middle-income countries could save thousands of lives, according to an Essay published January 15 in the open-access journal PLOS Medicine by Mark Tenforde of the University of Washington School of Medicine, and colleagues.
