Transgenic mice to visualize metastasis and inflammation

One of the major routes of tumor cell dissemination to form metastasis at distant organs in the body is the lymphatic system. To study this process, still poorly understood, and to gain information on which tumors prefer this route for dissemination and how to block it, researchers of the Spanish National Cancer Research Center, led by researcher Sagrario Ortega, have created transgenic mice in which, for the first time, the growth of the lymphatic vessels can be visualized in the whole animal, by a light-emitting reaction, as tumor progresses and forms metastasis.

Rare T follicular helper cells essential for developing antibody responses to infectious agents

The characterisation of a rare immune cell's involvement in antibody production and ability to 'remember' infectious agents could help to improve vaccination and lead to new treatments for immune disorders, say researchers from the Walter and Eliza Hall Institute.

Rare immune cells found to play a major role in lasting immunity

According to the latest research from the Walter and Eliza Hall Institute the characterization of a rare immune cell’s involvement in antibody production and ability to ‘remember’ infectious agents could help to improve vaccination and lead to new treatments for immune disorders.

Scientists use novel system to discover sequential firing of neurons

Princeton University researchers have used a novel virtual reality and brain imaging system to detect a form of neural activity underlying how the brain forms short-term memories that are used in making decisions.

Researchers observe membrane repair in real-time in a living organism

Every cell is enclosed by a thin double layer of lipids that separates the distinct internal environment of the cell from the extracellular space. Damage to this lipid bilayer, also referred to as plasma membrane, disturbs the cellular functions and may lead to the death of the cell. For example, downhill walking tears many little holes into the plasma membranes of the muscle cells in our legs.

CLR01 blocks toxic aggregations of proteins in mouse model of Parkinson's

Millions of people suffer from Parkinson's disease, a disorder of the nervous system that affects movement and worsens over time. As the world's population ages, it's estimated that the number of people with the disease will rise sharply. Yet despite several effective therapies that treat Parkinson's symptoms, nothing slows its progression.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Researchers track structural changes during formation of new memories

New connections between brain cells emerge in clusters in the brain as animals learn to perform a new task, according to a study published in Nature on February 19 (advance online publication). Led by researchers at the University of California, Santa Cruz, the study reveals details of how brain circuits are rewired during the formation of new motor memories.

Scientists observe maturation of immune cells in live zebrafish embryos

T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded for the first time in observing the maturation of immune cells in live zebrafish embryos.

Scientists discover how sense of touch is wired in skin and nervous system

Neuroscientists at the Johns Hopkins University School of Medicine have discovered how the sense of touch is wired in the skin and nervous system. The new findings, published Dec. 22 in Cell, open new doors for understanding how the brain collects and processes information from hairy skin.

ORMOSIL nanoparticles show promise as potential drug delivery vehicle

In the images of fruit flies, clusters of neurons are all lit up, forming a brightly glowing network of highways within the brain. It's exactly what University at Buffalo researcher Shermali Gunawardena was hoping to see: It meant that ORMOSIL, a novel class of nanoparticles, had successfully penetrated the insects' brains. And even after long-term exposure, the cells and the flies themselves remained unharmed.

Biologists develop radar to track ADAR's RNA editing activity in neurons

To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a "radar" for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.

Researchers reveal contribution of telomerase in controlling genetic code integrity

Researchers have revealed how a molecule called telomerase contributes to the control of the integrity of our genetic code, and when it is involved in the deregulation of the code, its important role in the development of cancer.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.

Transplantation of new neurons into damaged area of the brain could restore brain functions

Without neurons reacting to the blood leptin level, the brain does not control the feeling of hunger and fullness. This type of genetic defects results in severe obesity in humans and animals.

NIH grant to support Cedars-Sinai's Department of Neurology research

The National Institutes of Health has awarded a four-year, $1.4 million grant to Cedars-Sinai's Department of Neurology to study an unexpected recent discovery: After ischemic stroke - the type caused by a clogged artery but with no bleeding into the brain - a normal protein that plays a positive role in blood clotting escapes intact arteries and damages healthy brain cells.

Simple roundworm may serve as ideal skin wound healing lab model

The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly.
