Molecular ‘switch’ reverses chronic inflammation and aging

Chronic inflammation, which results when old age, stress or environmental toxins keep the body’s immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer’s and Parkinson’s to diabetes and cancer. Now, scientists at the University of California, Berkeley, have identified a molecular “switch” that controls the […]

iPS cells to regulate immune rejection upon transplantation

Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues. The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response […]

Adding Up

A merger of math and medicine may help to improve the efficacy of immunotherapies, potentially life-saving treatments that enhance the ability of the patient’s own immune system to attack cancerous tumors. By creating mathematical models that represent the complex interactions within the tumor microenvironment (TME), the nonmutated cells, connective tissues […]

Speeding Up Treatments for ALS

Therapeutic solutions for amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) could be on the horizon thanks to unexpected findings by University of Arizona researchers. Disease-prompting bundles of proteins found within cells are cleared by unexpected processes. ALS is the progressive degeneration of motor neurons that causes people to lose […]

Chromatin organizes into 3D 'forests' in single cells

A single cell contains the genetic instructions for an entire organism. This genomic information is managed and processed by the complex machinery of chromatin — a mix of DNA and protein in chromosomes whose function and role in disease are of increasing interest to scientists and engineers. Using mathematical modeling […]

Ultrasound Can Selectively Kill Cancer Cells

A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. Ultrasound waves—sound waves with frequencies higher than humans can hear—have been used as a cancer treatment before, albeit in a broad-brush approach: […]

Flickering Light Mobilizes Brain Chemistry That May Fight Alzheimer’s

For over a century, Alzheimer’s disease has confounded all attempts to treat it. But in recent years, perplexing experiments using flickering light have shown promise. Now, researchers have tapped into how the flicker may work. They discovered in the lab that the exposure to light pulsing at 40 hertz – […]

Tumbleweeds or fibrils: Tau proteins need to choose

New simulations by Rice University scientists tell a tale of two taus and how they relate to neurological disease. Their work suggests tau proteins take either of two paths to form aggregates suspected of promoting, and perhaps causing, Alzheimer’s and Pick’s (aka frontotemporal dementia) diseases. Precisely why remains a mystery, but figuring it out offers the […]

Loss of Lung Function Correlates with Epigenetic Age Acceleration

Epigenetic clocks are a topic of considerable interest in the research community. They are perhaps the most promising of the present techniques for assessing biological age, the closest to becoming a useful biomarker of aging. Epigenetic clocks are weighted algorithmic combinations of the DNA methylation status of various sites on the genome, reflecting changes that […]

Assessing ‘Stickiness’ of Tumor Cells Could Improve Cancer Prognosis

A team of researchers led by the University of California San Diego has created a device that measures how “sticky” cancer cells are, which could improve prognostic evaluation of patient tumors. The device is built with a microfluidic chamber that sorts cells by their physical ability to adhere to their […]

Diving Deep: Insights into Skeletal Features of Fish

From fragile ice fish deep in the Antarctic Ocean to flying fish gliding above the Caribbean Sea, fish have evolved a fascinating variety of skeletal traits. These traits not only help them adapt to their environments, but they also provide genetic insights into rare human skeletal disorders. Fish are not […]
