New treatment may destroy HIV's last refuge

UK scientists may have found a way to destroy HIV's last refuge. A study by Oxford University has confirmed that a treatment developed by a British company can remove the virus in its chosen hiding place, in laboratory conditions, offering hope of a viable treatment.

Key differences in immune response may explain young children’s proneness to infecion

Schools are commonly known as breeding grounds for viruses and bacteria, but this may not necessarily be linked to hygiene.

Researchers develop computer model for speed analysis of TB's complex life-cycle

Tuberculosis (TB), caused by the pathogen Mycobacterium tuberculosis, is a serious global health problem accounting for 1.3 million worldwide deaths annually.

Researchers find unexpected connection between two types of calming immune cells

Biologically speaking, we carry the outside world within us. The food we ingest each day and the trillions of microbes that inhabit our guts pose a constant risk of infection--and all that separates us from these foreign entities is a delicate boundary made of a single layer of cells.

Autologous stem cell transplant safe, effective for HIV-associated lymphoma patients

New research published online today in Blood Journal of the American Society of Hematology (ASH), challenges the generally held belief that individuals with HIV and aggressive lymphoma are not candidates for standard treatment.

Study captures interactions of HIV-infected immune cells in living animal

By watching brightly glowing HIV-infected immune cells move within mice, researchers at the Icahn School of Medicine at Mount Sinai have shown how infected immune cells latch onto an uninfected sister cell to directly transmit newly minted viral particles.

Improved research tool may open door to effective HIV vaccine designs

Vaccines are usually medicine's best defense against the world's deadliest microbes. However, HIV is so mutable that it has so far effectively evaded both the human immune system and scientists' attempts to make an effective vaccine to protect against it.

Gene dysregulation makes immune therapies less effective against metastatic melanoma

Patients who don't respond to treatments that use their own immune cells to destroy tumors, called tumor infiltrating lymphocytes, share changes in mechanisms that switch genes on or off in those cells, according to study results presented at the annual meeting of the American Society for Clinical Oncology on June 4 in Chicago.

Researchers discover ANKRD55 gene linked to multiple sclerosis

The Ikerbasque researcher Koen Vandenbroeck, who heads the Neurogenomiks laboratory which reports to the Achucarro centre and the UPV/EHU-University of the Basque Country, together with other national and international groups, has shown that a genetic variant in the 5q11 chromosome, which is associated with susceptibility to developing multiple sclerosis, greatly regulates a gene known as ANKRD55. ANKRD55 is a gene with an unknown function.

ART alone not sufficient to reduce arterial inflammation among HIV-infected patients, study finds

Initiating antiretroviral therapy (ART) soon after diagnosis of an HIV infection did not prevent the progression of significant arterial inflammation in a small group of previously untreated patients.

Gene editing technology helps excise segment of HIV-1 DNA from genomes of living animals

Using gene editing technology, researchers at the Lewis Katz School of Medicine at Temple University have, for the first time, successfully excised a segment of HIV-1 DNA - the virus responsible for AIDS - from the genomes of living animals.

New skin test for TB infection proves safe, effective in clinical trials

A new skin test for tuberculosis infection has proven safe, easy to administer and accurate in two Phase III clinical trials, according to research presented at the ATS 2016 International Conference.

Study shows expression of high-affinity TCRs linked with spontaneous control of HIV infection

A small number of patients infected by HIV spontaneously control viral replication without antiretroviral therapy, and do not develop the disease. The ability of these rare patients, known as "HIV controllers", to suppress HIV replication appears to be down to a highly effective immune response.

Scientists prove effectiveness of gene editing system in eliminating HIV from DNA of CD4+ T-cells

In 2014, a team of researchers in the Lewis Katz School of Medicine at Temple University became the first to successfully eliminate the HIV-1 virus from cultured human cells.

Point-of-care test could help detect TB in HIV-positive individuals

An international review team has prepared a Cochrane systematic review to assess the accuracy of a point-of-care urine test for diagnosing and screening tuberculosis (TB) in people living with human immunodeficiency virus (HIV).

UCLA, Danish research yields proof that treatment-as-prevention strategy could eliminate HIV

Worldwide, about 35 million people are living with HIV. The World Health Organization and the Joint United Nations Programme on HIV/AIDS plan to use an approach called "treatment as prevention" to eliminate the global pandemic, which the WHO says will have occurred when only one person out of 1,000 becomes infected each year.

New antibody-based therapy may provide better strategy for long-term control of HIV

The development of antiretroviral therapy, a combination of drugs that slows the replication of HIV in the body, has transformed the treatment of this infection. What was once a certain death sentence is now a chronic condition that people can live with for decades.

Oral administration of Jakinibs reduces Parkinson's disease pathogenesis in rat model

University of Alabama at Birmingham researchers report the first documentation that suppressing a key cell-signaling pathway in a rat model of Parkinson's disease reduces pathogenesis. Oral administration of AZD1480 — one of the JAK/STAT pathway inhibitors generally known as Jakinibs — lessened the destructive inflammation and nerve cell degradation in the area of the brain affected by Parkinson's.

Real risk of rebound syndrome following fingolimod cessation for MS

Rebound syndrome following cessation of fingolimod for multiple sclerosis occurs at a clinically relevant rate, shows research, prompting the need for further study on how best to sequence and discontinue such drugs.
