Targeted therapies suppress T cell activity that could actually help fight tumors

In many cases, targeted therapies for cancer are preferred as treatments over chemotherapy and surgery because they attack and kill cancer cells with specific tumor-promoting mutations while sparing healthy, normal cells that do not express these mutations.

Mutations in cancerous lymphoma cells break through four protein locks

Protein chemists at Johns Hopkins report they are closer to explaining why certain blood cancers are able to crack a molecular security system and run rampant.

Findings could be final puzzle piece in developing effective dengue vaccine

In a small clinical trial led by the Johns Hopkins Bloomberg School of Public Health, researchers say that a promising single-dose dengue vaccine, developed by scientists at the National Institutes of Health, was 100 percent effective in preventing human volunteers from contracting the virus, the most prevalent mosquito-borne virus in the world.

Kanazawa University researchers identify molecular mechanism that links liver disease and obesity

Kanazawa University researchers find similarities in the impeded signalling between central insulin activity and glucose production in the liver for both obese mice and mice that have had the vagus nerve removed.

Neural stem cells from T cell-derived iPSCs provide neurological disease model

Researchers in Japan report that neural stem cells derived from readily available T cell-derived iPSCs provide a neurological disease model when cultured in a novel protocol developed by them. The findings are important for the treatment of Parkinson’s disease and are published in Stem Cell Reports, March 2016.

Scientists find surprising link between iPS cell reprogramming, blood cell formation and cancer

The ability to reprogram cells has revolutionized stem cell research with major implications for almost all fields of modern biology. A decade ago Shinya Yamanaka described a procedure that revolutionized stem cell biology. Using a genetic trick that introduces a cocktail of four genes into cultured cells from human biopsies, he was able to generate induced pluripotent stem cells (iPS) from mature skin or blood cells

New microfluidic biosensor can identify white blood cells quickly for AIDS diagnosis

Researchers from the University of Illinois at Urbana-Champaign have developed a highly sensitive biosensor based on a differential immuno-capture technology that can detect sub-populations of white blood cells. As part of a small, disposable biochip, the microfluidic biosensor can count CD4+/CD8+ T cells quickly and accurately for AIDS diagnosis in the field.

Synthetic nanoparticle can light up and treat atherosclerotic plaques

Atherosclerosis, a disease in which plaque builds up inside arteries, is a prolific and invisible killer, but it may soon lose its ability to hide in the body and wreak havoc. Scientists have now developed a nanoparticle that functionally mimics nature's own high-density lipoprotein (HDL). The nanoparticle can simultaneously light up and treat atherosclerotic plaques that clog arteries. Therapy with this approach could someday help prevent deadly heart attacks and strokes.

Research uncovers biological differences between male, female breast cancers

Male breast cancer (Male BC) has important biological differences that distinguish it from female breast cancer, but to date these have been little studied and Male BC patients have been excluded from many clinical trials in breast cancer.

Low bone mass higher in HIV-infected males than in females

Accumulating evidence suggests that rates of low bone mass are greater in HIV-infected males than in females. Researchers led by Grace Aldrovandi, MD, chief of the Division of Infectious Diseases at Children's Hospital Los Angeles, studied 11 biomarkers associated with inflammation, bone loss and/or bone formation in about 450 individuals - assessed by sex and HIV status - to try to determine causes of this differential bone loss.

New procedure allows kidney transplants from incompatible donors

Researchers have found a way to stop patients rejecting kidneys that have come from incompatible donors, potentially slashing the waiting time for thousands of people in desperate need of the procedure.

Vanderbilt investigators isolate human antibodies against H7 bird flu

Researchers at Vanderbilt University Medical Center have isolated human antibodies against a type of bird flu that has killed more than 200 people in China since 2012 and which may pose a worldwide pandemic threat.

Consuming green tea with dietary iron may lessen health benefits of green tea

Green tea is touted for its many health benefits as a powerful antioxidant, but experiments in a laboratory mouse model of inflammatory bowel disease suggest that consuming green tea along with dietary iron may actually lessen green tea's benefits.

Research highlights association of western diet with Alzheimer's disease

Recent research has established associations between certain environmental factors, including eating a western diet and being sedentary, with an increased susceptibility to Alzheimer's disease. In fact, it is estimated that a combination of diet and inactivity contributes to as many as 25% of Alzheimer's cases. Nonetheless, little is known about the exact disease mechanisms and how or why this increasingly common middle-age lifestyle can play such a big role in subsequent cognitive function.

Johns Hopkins Greenberg Bladder Cancer Institute awards grants for 10 bladder cancer research projects

A study of obesity and related metabolic changes on bladder cancer incidence and deaths, and a plan to use stem cells to grow novel urinary tubes are among 10 research projects awarded funding by the Johns Hopkins Greenberg Bladder Cancer Institute.

Researchers find Achilles' heel of acute lymphoblastic leukemia

Researchers at The Ottawa Hospital and the University of Ottawa have found the Achilles' heel of one of the most aggressive forms of leukemia that affects both children and adults. They have also identified a possible new treatment that exploits this fatal weakness.

Researchers find way to boost the body's natural cancer-killing cells

The immune cells, called natural killer cells, hunt and destroy foreign cells in the body, including cancer cells that spread and form tumours.
