New breast cell types discovered by multidisciplinary research team

Tue, 21 Nov 17 00:06:40 -0800

A joint effort by breast cancer researchers and bioinformaticians has provided new insights into the molecular changes that drive breast development.

The main switch

Tue, 21 Nov 17 00:10:00 -0800

The three-dimensional folding of DNA provides important epigenetic mechanisms in the formation of cardiac muscle cells.

Good cells gone bad

Tue, 21 Nov 17 00:15:10 -0800

A new study from The Scripps Research Institute (TSRI) is the first to show precisely how a process in nerve cells, called the S-nitrosylation (SNO) reaction, may contribute to Parkinson's disease.

Diabetes: Immune system can regulate insulin

Tue, 21 Nov 17 00:00:10 -0800

Inflammation processes are responsible for the failure of insulin production in diabetes patients. The patients' own immune systems can contribute to treatment of this disease: researchers at the University of Basel and University Hospital Basel have found a feedback mechanism that could help maintain insulin production in overweight sufferers, as they report in the journal Immunity.

How rogue immune cells cross the blood-brain barrier to cause multiple sclerosis

Tue, 21 Nov 17 00:03:00 -0800

Drug designers working on therapeutics against multiple sclerosis should focus on blocking two distinct ways rogue immune cells attack healthy neurons, according to a new study in the journal Cell Reports.

Brain cell advance brings fresh hope for CJD therapies

Mon, 20 Nov 17 00:07:20 -0800

Scientists at the University of Edinburgh have developed a new system to study Creutzfeldt-Jakob disease in the laboratory, paving the way for research to find treatments for the fatal brain disorder.

Zika-related nerve damage caused by immune response to the virus

Mon, 20 Nov 17 00:09:30 -0800

The immune system's response to the Zika virus, rather than the virus itself, may be responsible for nerve-related complications of infection, according to a Yale study. This insight could lead to new ways of treating patients with Zika-related complications, such as Guillain-Barré syndrome, the researchers said.

UofL researchers discover key signaling protein for muscle growth

Mon, 20 Nov 17 00:10:00 -0800

Researchers at University of Louisville have discovered the importance of a well-known protein, myeloid differentiation primary response gene 88 (MyD88), in the development and regeneration of muscles. Ashok Kumar, Ph.D., professor and distinguished university scholar in UofL's Department of Anatomical Sciences and Neurobiology, led a team of researchers who have described the protein's critical role in the growth and repair of skeletal muscles, both in post-natal development and in the regeneration of injured adult muscles.

Nanoparticles could allow for faster, better medicine

Mon, 20 Nov 17 00:10:30 -0800

Gold nanoparticles could help make drugs act more quickly and effectively, according to new research conducted at Binghamton University, State University of New York.

Cell cycle proteins help immune cells trap microbes with nets made of DNA

Mon, 20 Nov 17 00:13:00 -0800

In your bloodstream, there are immune cells called neutrophils that, when faced with a pathogenic threat, will expel their DNA like a net to contain it. These DNA snares are called neutrophil extracellular traps or NETs. Researchers from Germany and the United States describe an important step in how these NETs are released and how they stop a fungus from establishing an infection in mice and human cells in the journal Developmental Cell.

PSU researchers design survey to tap students' motivation in STEM

Mon, 20 Nov 17 00:15:10 -0800

Researchers at Portland State University are learning more about undergraduates' experience in science, technology, engineering and math (STEM) classes and sharing a set of survey questions that will help researchers and educators at other universities do the same. This survey was developed by a team of researchers in PSU's STEM Equity and Education Institute with the help of instructors in chemistry, biology and physics.

UVA researchers discover a new target for 'triple-negative' breast cancer

Mon, 20 Nov 17 00:02:50 -0800

One of the most difficult to treat cancers - triple-negative breast cancer - may be vulnerable to a new approach, an early study indicates.

The future of cell culture: A new continuous bioprocess developed

Fri, 17 Nov 17 00:03:50 -0800

Scientists at Newcastle University, UK have developed a revolutionary technique to allow the continuous production and collection of cells.

University of Guelph professor identifies protein key to cancer cells ability to spread

Fri, 17 Nov 17 00:08:50 -0800

U of G scientists have made a discovery that could reduce the spread of cancer by hindering a protein that binds cancer cells together and allows them to invade tissues. The groundbreaking study identified a protein, known as cadherin-22, as a potential factor in cancer metastasis, or spread, and showed that hindering it decreased the adhesion and invasion rate of breast and brain cancer cells by up to 90 percent.

Brain astrocytes linked to Alzheimer's disease

Fri, 17 Nov 17 00:08:10 -0800

Astrocytes, the supporting cells of the brain, could play a significant role in the pathogenesis of Alzheimer's disease (AD), according to a new study from the University of Eastern Finland. This is the first time researchers discovered a direct association between astrocytes and AD. Published in Stem Cell Reports, the study investigated the brain cell function of familial AD patients by using stem cell technologies.

Investigating patterns of degeneration in Alzheimer's disease

Fri, 17 Nov 17 00:10:40 -0800

Alzheimer's disease (AD) is known to cause memory loss and cognitive decline, but other functions of the brain can remain intact. The reasons cells in some brain regions degenerate while others are protected is largely unknown. In a paper to be published in Stem Cell Reports, researchers from Brigham and Women's Hospital have found that factors encoded in the DNA of brain cells contribute to the patterns of degeneration, or vulnerability, in AD.

How a poorly explored immune cell may impact cancer immunity and immunotherapy

Fri, 17 Nov 17 00:13:20 -0800

The immune cells that are trained to fight off the body's invaders can become defective. It's what allows cancer to develop. So most research has targeted these co-called effector T-cells. But a new study takes a step back and considers: What if the problem isn't with the effector T-cells but starts higher up the cellular chain?

Deletion of a stem cell factor promotes TBI recovery in mice

Fri, 17 Nov 17 00:01:10 -0800

Researchers found that conditional deletion of Sox2 -- the gene encoding the SOX2 stem cell transcription factor -- and the associated dampening of astrocyte reactivity appear to promote functional recovery, including behavioral recovery, after traumatic brain injury, said Dr. Zhang, a W.W. Caruth, Jr. Scholar in Biomedical Research.
