Caltech researchers find antibody that can detect, neutralize HIV viruses in infected patients

Proteins called broadly neutralizing antibodies (bNAbs) are a promising key to the prevention of infection by HIV, the virus that causes AIDS. bNAbs have been found in blood samples from some HIV patients whose immune systems can naturally control the infection.

Genetic mutations in deadly Ebola virus appear to block antibody-based treatments

Genetic mutations called "escape variants" in the deadly Ebola virus appear to block the ability of antibody-based treatments to ward off infection, according to a team of U.S. Army scientists and collaborators. Their findings, published online this week in the journal Cell Reports, have implications for the continued development of therapeutics to treat Ebola virus disease, which has claimed the lives of over 11,000 people in West Africa since last year.

New UCLA study finds novel approach that may help delay declines in health

Why do some people remain healthy into their 80s and beyond, while others age faster and suffer serious diseases decades earlier? New research led by UCLA life scientists may produce a new way to answer that question -- and an approach that could help delay declines in health.

Researchers identify new epigenetic markers for colorectal cancer

Researchers at Nanjing University, China, found new epigenetic markers for colorectal cancer which may offer a new approach for treatment.

New study reveals link between cardiorespiratory fitness, brain activation and executive function in older adults

The aging process is associated with declines in brain function, including memory and how fast our brain processes information, yet previous research has found that higher levels of cardiorespiratory fitness in older adults leads to better executive function in the brain, which helps with reasoning and problem solving. Higher cardiorespiratory fitness levels have also been found to increase brain volume in key brain regions.

New technique could improve selectivity of cancer drugs, decrease unwanted side effects in future

A class of therapeutic drugs known as protein kinase inhibitors has in the past decade become a powerful weapon in the fight against various life-threatening diseases, including certain types of leukemia, lung cancer, kidney cancer and squamous cell cancer of the head and neck.

Online course offered in October on zoonotic disease

Recent outbreaks of plague, tularemia and increasing incidents of rabies exposure highlight the importance of zoonotic disease education for physicians and public health professionals.

Penn Medicine researchers show that DNA editing errors can lead to cancer

Sometimes when the immune system makes small mistakes, the body amplifies its response in a big way: Editing errors in the DNA of developing T and B cells can cause blood cancers. Now, researchers from the Perelman School of Medicine, University of Pennsylvania have shown that when the enzyme key to cutting and pasting segments of DNA hits so-called "off-target" spots on a chromosome, the development of immune cells can lead to cancer in animal models.

New collaboration may allow researchers to develop potential gene therapies for pediatric diseases

A new collaboration between Seattle Children's Research Institute and bluebird bio, Inc., a biotechnology company based in Cambridge, Mass. and Seattle, will allow researchers to develop potentially transformative gene therapies for severe genetic and rare pediatric diseases. The collaboration supports pediatric researchers in Seattle who will work with bluebird bio scientists and the company's gene editing technology to research potential cures for genetic pediatric diseases.

Targeting exhausted immune cells may change prognosis for leukemia relapse patients after transplant

Targeting exhausted immune cells may change the prognosis for patients with acute myeloid leukemia (AML) relapse after a stem cell transplant, according to Penn State College of Medicine researchers.

Researchers find key cellular enzyme that could be effective drug target for urologic cancer cells

Researchers at the SUNY Upstate Medical University have found that a key cellular enzyme, c-Abl, could be an effective drug target in cancer cells for urologic cancers, such as prostate and kidney.

NYU's Jin Kim Montclare develops dual-delivery system to potentially treat multi-drug resistant cancer cells

The National Science Foundation recently funded research aimed at developing an engineered protein-lipid system that simultaneously delivers genes and drugs for the potential treatment of multi-drug resistant cancer cells. The dual-delivery system could also apply to diabetes and other conditions requiring a variety of therapeutic approaches.

Luteolin may reduce risk of breast cancer in some women, find MU researchers

More than 100 women die from breast cancer every day in the United States. The odds increase in postmenopausal women who have taken a combined estrogen and progestin hormone replacement therapy; these women also have an increased risk of developing progestin-accelerated breast tumors.

Scientists elucidate genetic interaction that may prove key to development, progression of glaucoma

Scientists at the University of California, San Diego School of Medicine have elucidated a genetic interaction that may prove key to the development and progression of glaucoma, a blinding neurodegenerative disease that affects tens of millions of people worldwide and is a leading cause of irreversible blindness.

New research shows direct evidence of greater mitochondrial damage in Gulf War veterans

One in four Gulf War veterans suffers from Gulf War Illness (GWI). The condition is characterized by unexplainable chronic fatigue, muscle pain and cognitive dysfunction and may be associated with exposure to chemicals, many identified as genotoxins, during deployment.

Hastings Center receives NSF grant for ethical analysis of next-generation prenatal genetic tests

Prenatal testing is changing dramatically. With greatly expanded low-cost genetic tests - some as simple as a maternal blood test - prospective parents will soon be able to learn far more, far earlier, than ever before about their fetuses' medical conditions and risks, and some nonmedical traits.

Inhibition of Tyk2 enzyme promotes anti-cancer activity

Tyrosine kinase 2 (Tyk2) is an enzyme involved in intracellular signalling and has an important role in activating the immune system.

Professor Hawking to open inaugural Cambridge Rare Disease Summit on 14 September, 2015

Professor Hawking was famously diagnosed with the rare motor neuron disease at 21, and was told science had no answers. He has of course gone on to live a long and productive life, and the Cambridge Rare Disease Summit will discuss how to make this a reality for the 3.5 million other Britons who live with a rare disease.

Chronic alcohol consumption disrupts liver molecular circadian clock, leads to alcoholic liver disease

The activity of an organ in the body changes through the day and is governed by its internal clock, also known as a circadian clock. Staying on a circadian schedule is important for health, and disruptions lead to disease.

Intake of cocoa flavanols improves cardiovascular function, lowers blood pressure

Two recently published studies in the journals Age and the British Journal of Nutrition (BJN) demonstrate that consuming cocoa flavanols improves cardiovascular function and lessens the burden on the heart that comes with the ageing and stiffening of arteries.
