New approach to destroy HIV reservoirs

Current HIV treatments need to be taken for life by those infected as antiretroviral therapy is unable to eliminate viral reservoirs lurking in immune cells. Institut Pasteur scientists have identified the characteristics of CD4 T lymphocytes that are preferentially infected by the virus - it is their metabolic (or energy-producing) activity1 that enables the virus to multiply.

Liver immune cells contain inert HIV and are unlikely to reproduce infection, study reveals

In a proof-of-principle study, researchers at Johns Hopkins revealed that certain immune system cells found in the human liver, called liver macrophages, contain only inert HIV and aren't likely to reproduce infection on their own in HIV-infected people on long-term antiretroviral therapy.

ECDC and WHO release latest data on HIV epidemic in the European Region

The European Centre for Disease Prevention and Control and the WHO Regional Office for Europe release the latest data on the HIV epidemic in the European Region, marking the 30th anniversary of World AIDS Day.

Reducing cellular proliferation could help deplete HIV reservoir and lead to a functional cure

A majority of the HIV-infected cells that persist in HIV-infected individuals even during suppressive antiretroviral therapy originated from cellular proliferation, not viral replication, according to new research published in Nature Communications.

Mechanisms that govern HIV latency differ in the gut and blood, finds study

Mechanisms that govern HIV transcription and latency differ in the gut and blood, according to a study published November 15 in the open-access journal PLOS Pathogens by Steven Yukl of San Francisco Veterans Affairs Medical Center and the University of California, San Francisco, and colleagues.

Treating children with 'bubble baby disease'

An international study published in the journal Blood by researchers led by Dr. Elie Haddad, a pediatric immunologist and researcher at CHU Sainte-Justine and professor at Université de Montréal, highlights the urgent need to develop better treatment strategies for patients suffering from severe combined immune deficiency.

Small populations of normal T cells could modify disease severity in patients with XLP1

Human SH2D1A mutations resulting in X-linked lymphoproliferative syndrome type 1 are associated with a unique susceptibility to the Epstein-Barr virus, which may lead to fatal infectious mononucleosis.

Researchers identify pathway to resolve allergic asthma

A group of Brazilian researchers succeeded in preventing allergic asthma from progressing in experimental models by increasing the amount of a protein. This increase, in turn, blocked the CD4+ T lymphocytes responsible for producing a cytokine that triggers a cascade of events resulting in the onset and progression of the disease.

New approach may lead to protective vaccines for immunocompromised patients

A study led by Som Nanjappa at the University of Illinois College of Veterinary Medicine identifies a cellular target that may improve efficacy in vaccines designed to protect immunocompromised individuals from potentially deadly opportunistic infections.

Gut microbiota could play greater role in pathogenesis of MS than previously thought

In multiple sclerosis, a defective response of the body’s own immune system leads to brain tissue damage. Gastrointestinal microbiota could play a far greater role in the pathogenesis of the disease than previously assumed, researchers at the University of Zurich have now found.

NCCN adds COPIKTRA capsules to NCCN Guidelines for follicular lymphoma

Verastem, Inc., focused on developing and commercializing medicines to improve the survival and quality of life of cancer patients, today announced that the National Comprehensive Cancer Network added COPIKTRA (duvelisib) capsules to the Clinical Practice Guidelines in Oncology (NCCN Guidelines) for follicular lymphoma.

Study shows possibility of using PET imaging to manage chronic liver diseases

While liver biopsies are powerful and reliable, they are also invasive, painful, limited and subject to complications. These effects may soon be a thing of the past for some patients thanks to new research showing PET imaging with the 18F-FAC radiotracer can be used as a non-invasive substitute. The study is featured in the October issue of The Journal of Nuclear Medicine.

Discovery opens door to new therapies for type 1 diabetes

Researchers at St Vincent’s Institute in Melbourne have identified a key target of the immune response that causes type 1 diabetes.

Overlooked immune cells could play a key role in cancer immunotherapy, claims new study

Cancer immunotherapy is a relatively new method of treating cancer and has succeeded with some refractory tumors. However, it doesn’t always work, why not?

New research finds that MHC-II molecules have more influence on tumors than MHC-I

Cancer immunotherapy -- efforts to boost a patient's own immune system, allowing it to better fight cancer cells on its own -- has shown great promise for some previously intractable cancers.

NIH launches clinical trial to test infusions of combination antibodies in people with HIV

A clinical trial testing infusions of combination antibodies in people living with HIV has begun at the National Institutes of Health.

QIAGEN and DiaSorin launch automated, CE-marked workflow for high-throughput TB screening

QIAGEN N.V. and DiaSorin today announced the introduction of an automated, CE-marked workflow for QIAGEN’s QuantiFERON-TB Gold Plus Blood Collection Tubes (QFT-Plus BCT) and a novel DiaSorin LIAISON Test on widely used immunodiagnostic instruments from DiaSorin.

New program combines basic science and social benefits to address HIV risk among young women

A program established by investigators from the Ragon Institute of Massachusetts General Hospital, MIT and Harvard is addressing the persistently elevated risk of HIV infection among young women in South Africa from two angles - first, investigating biological factors that modulate infection risk along with the early immunologic events following viral exposure, and second, alleviating the socioeconomic factors that limit opportunities for young women, the group at greatest risk of infection in the region of the world hardest hit by the HIV epidemic.

Researchers describe mechanism that sets stage for fate decision of T cells

After a pathogen infects the body, the immune system responds with a remarkable -- and remarkably complicated -- cascade of events.

Mouse study suggests new therapeutic approach to treat heart failure

A heart attack triggers an acute inflammatory response, followed by resolution of inflammation and wound healing. A severe heart attack, however, can cause chronic and sustained inflammation that leads to heart failure and death.
