Mystery solved: New study reveals how DNA repair genes play a major role in Huntington's disease

A new UCLA Health study has discovered in mouse models that genes associated with repairing mismatched DNA are critical in eliciting damages to neurons that are most vulnerable in Huntington's disease and triggering downstream pathologies and motor impairment, shedding light on disease mechanisms and potential new ways to develop therapies. 

Huntington’s disease is one of the most common inherited neurodegenerative disorders that typically begins in adulthood and worsens over time. Patients begin to lose neurons in specific regions of the brain responsible for movement control, motor skill learning, language and cognitive function. Patients typically live 15 to 20 years after diagnosis with symptoms worsening over time. There is no known cure or therapy that alters the course of the disease.

The cause of Huntington's disease was discovered over three decades ago--a "genetic stutter" mutation involves repeats of three letters of the DNA, cytosine-adenine-guanine (CAG), in a gene called huntingtin. Healthy individuals usually have 35 or fewer CAG repeats, but people inherited with mutation of 40 or more repeats will develop the disease. The more CAG repeats a person inherits, the earlier the disease onset occurs. However, how the mutation causes the disease remains poorly understood.

A scholarly report in the journal Science Advances from researchers at the University of Kansas shows a new eco-friendly method for separating the chemicals found in common refrigerants for easier recycling at industrial scale.

“The motivation of this work is to enable separation of highly complex gaseous refrigerant mixtures,” said lead author Abby Harders, who performed the research as a KU doctoral student in the research group of co-author Mark Shiflett, Foundation Distinguished Professor of Chemical and Petroleum Engineering. “This effort has been driven by climate legislation phasing out certain hydrofluorocarbon (HFC) refrigerants.”

The paper's key innovation uses membranes — amorphous fluorinated polymers, to be specific — that efficiently isolate complex refrigerant mixtures. Other separation methods, like distillation, are less effective because of the complex composition of the mixtures. Harders said the membranes are fabricated to allow some gases to pass through while restricting others — resulting in effective purification.

To demonstrate the technology could scale to industrial viability, the team — including many associated with KU’s Wonderful Institute for Sustainable Engineering — developed a custom-coating process to create submicron coatings on the membrane’s porous supports, creating composite hollow fibers. The results show a functional prototype, proving the technology’s usefulness to firms engaged in refrigerant recovery and reuse. 

Innovative target design leads to surprising discovery in laser-plasma acceleration

Researchers studying laser-driven proton acceleration introduced an innovative, self-replenishing water sheet target to address the inefficiency of replacing targets after each laser pulse. The target had a surprising side effect, resulting in a naturally focused, more tightly aligned proton beam.

Scientists have developed a groundbreaking method for generating fast, bright proton beams using a high-repetition-rate laser-plasma accelerator. This work, published in Nature Communications, resolves several long-standing challenges and ushers this technology to the threshold of real-world applications – all thanks to a stream of water. 

“These exciting results pave the way for new applications of relativistic high-power lasers for applications in medicine, accelerator research, and inertial fusion,” said Siegfried Glenzer, professor of photon science and the director of the High Energy Density Science division at the Department of Energy's SLAC National Accelerator Laboratory.

It also marks 15 years since King Abdullah University of Science and Technology (KAUST) was established as the first mixed-gender university in Saudi Arabia. Since then, KAUST has been a pioneer in championing women and girls in science in the Kingdom and across the Middle East. Today we celebrate all KAUST’s female graduates and scientists, many of whom have achieved remarkable success in their careers, such as becoming professors at leading universities worldwide, taking leadership roles in Saudi ministries and giga-projects, and founding tech companies that drive investment and create jobs in the Kingdom.     

KAUST's world-class research and education, supported by initiatives and projects like the KAUST Gifted Student Program (KGSP), the Ibn Rushd fellowship program and the KAUST Entrepreneurship Center, have been instrumental in this success. These programs nurture talent, foster innovation and empower women to excel in science and technology.   

Opening for a new type of drug for Alzheimer’s Disease

A complementary drug to combat Alzheimer’s disease could target a specific part of the nerve cell protein tau. This is the finding of research from the University of Gothenburg, which also offers a better way to measure the effect of treatment among patients.

Researchers from the University of Gothenburg, together with colleagues from the University of Pittsburgh in the US, published their findings in the journal Nature Medicine.

The study provides insights into what happens during the earliest phase when the protein tau is transformed into thread-like strands (fibrils) in the nerve cells. This is one of the processes in Alzheimer’s disease and occurs alongside the formation of amyloid plaques. In healthy individuals, the protein tau stabilizes the tubular building blocks (microtubules) that make up the long projections of the nerve cells.

During the development of Alzheimer’s disease, tau undergoes pathological changes. First, tau forms small, soluble aggregates that are secreted from the nerve cells and are thought to be able to spread these changes to other nerve cells. The protein is then converted into larger, harmful, thread-like strands in the nerve cells.

How Botox enters our cells

Botulinum toxin A1, better known under the brand name Botox, is not only a popular cosmetic agent, but also a highly effective bacterial neurotoxin that – when carefully dosed – can be used as a drug. It blocks the transmission of signals from nerves to muscles: This can relax muscles under the skin, which in cosmetics is used to smooth facial features. It can also alleviate conditions that are caused by cramping muscles or faulty signals from nerves, such as spasticity, bladder weakness, or misalignment of the eyes. However, if the dose is too high, the use of Botox can be fatal due to paralysis of the respiratory muscles. This can happen as a result of bacterial meat poisoning and is called botulism.

To make the most effective use of botulinum toxin as a drug, to precisely control its action, and to expand the range of possible applications of the toxin, researchers want to better understand how the toxin enters nerve cells to exert its effect. Until now, little was known about this.  “This is mainly because we had no structural data on what the toxin looks like in its full-length form when binding to its nerve cell's receptor,” says Richard A. Kammerer of the PSI Center for Life Sciences. So far there had only been studies on the structure of individual domains of the toxin – that is, specific parts of its complex molecular structure – and on the structure of such domains in complex with the receptor or one of its domains. 

Collection of tiny antennas can amplify and control light polarized in any direction

Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cell phones and more. Researchers in the McKelvey School of Engineering at Washington University in St. Louis imagines a future where antennas reshape even more applications.

Their new metasurfaces, ultra-thin materials made of tiny nanoantennas that can both amplify and control light in very precise ways, could replace conventional refractive surfaces from eyeglasses to smartphone lenses and improve dynamic applications such as augmented reality/virtual reality and LiDAR.

While metasurfaces can manipulate light very precisely and efficiently, enabling powerful optical devices, they often suffer from a major limitation: Metasurfaces are highly sensitive to the polarization of light, meaning they can only interact with light that is oriented and traveling in a certain direction. While this is useful in polarized sunglasses that block glare and in other communications and imaging technologies, requiring a specific polarization dramatically reduces the flexibility and applicability of metasurfaces.

Influenza A virus particles strategically adapt their shape—to become either spheres or larger filaments—to favor their ability to infect cells depending on environmental conditions, according to a new study from National Institutes of Health (NIH) scientists. This previously unrecognized response could help explain how influenza A and other viruses persist in populations, evade immune responses, and acquire adaptive mutations, the researchers explain in a new study published in Nature Microbiology.

The study, led by intramural researchers at NIH’s National Institute of Allergy and Infectious Diseases (NIAID), was designed to determine why many influenza A virus particles exist as filaments. The filament shape requires more energy to form than a sphere, they state, and its abundance has been previously unexplained. To find the answer, they developed a way to observe and measure real-time influenza A virus structure during formation.

University of Queensland researchers discovered that nearly 70 per cent of suspected frontotemporal dementia patients ultimately did not have the disease, in a study aimed at identifying factors that contribute to misdiagnosis of this notoriously difficult to diagnose disorder.

Psychiatrist Dr Joshua Flavell, working with cognitive neurologist Professor Peter Nestor at the Mater Hospital Memory and Cognitive Disorders clinic and UQ’s Queensland Brain Institute, analyzed data from 100 patients suspected of having frontotemporal dementia who had been referred by specialist physicians like neurologists, psychiatrists or geriatricians.

“Of the 100 patients, 34 were true-positive, and 66 were false-positive for frontotemporal dementia,” Dr Flavell said.

“We found that misinterpretation of brain scans, particularly nuclear imaging, led to 32 patients being incorrectly diagnosed.
