Study reveals mechanism behind failed remyelination in MS

Researchers have discovered that in adult stem cells, the activation of a specific transcription factor induces pathological quiescence and that this is deactivated in MS.

Neuroscience-protein that creates borders inside the brain

Boundaries between different regions of the brain are essential for the brain to function. Research to-date has shown that molecular machineries located at the cell membrane such as cell adhesion molecules are responsible for regulating the boundary formation.

Weakened metabolism of immune T cells may account for serious complications in elderly

The elderly suffer more serious complications from infections and benefit less from vaccination than the general population.

Face masks may offer protection against staph bacteria for hog farm workers and their household members

Face masks appear to provide important protection against drug-resistant Staphylococcus aureus bacteria for hog farm workers and for household members to whom they might otherwise transmit the bacteria, according to a study led by scientists at Johns Hopkins Bloomberg School of Public Health.

Unraveling the complexity of cancer biology can prompt new avenues for drug development

Unraveling the complexity of cancer biology can lead to the identification of new molecules involved in breast cancer and prompt new avenues for drug development. And proteogenomics, an integrated, multipronged approach, seems to be a way to do it.

Research findings could lead to new targets for cancer-fighting therapeutics

A molecular pathway that's frequently mutated in many different forms of cancer becomes active when cells push parts of their membranes outward into bulging protrusions, Johns Hopkins researchers report in a new study.

Natural flavonoid is effective at treating leishmanisis infections, study shows

Current treatment options for the parasitic disease leishmaniasis are largely ineffective, expensive, and tend to be plagued by resistant parasites and side effects. Now, researchers reporting in PLOS Neglected Tropical Diseases have showed that a natural flavonoid is effective at treating Leishmania amazonensis infections.

Scientists discover cellular mechanism that triggers pneumonia in humans

The situation is relatively common, especially in winter. You come down with the flu, which lasts longer than usual. A few days later, you discover you have pneumonia.

Breast tumors recruit bone marrow cells to boost their growth, study reveals

Tel Aviv University researchers have discovered that breast cancer tumors boost their growth by recruiting stromal cells that originate in bone marrow.

Study evaluates placental mesenchymal stem cell sheets for myocardial repair and regeneration

The placenta offers an abundant source of placenta-derived mesenchymal stem cells (pMSCs), which a new study has shown can readily form cell sheets that could be implanted in children with congenital heart defects and offer benefits for heart repair and regeneration compared to commonly used synthetic material-based scaffolds. Congenital heart disease is the leading cause of birth-defect-related illness and death.

New technology for profiling genetic makeup of myeloma tumor cells developed

Cancer arises when cells lose control. Deciphering the "blueprint" of cancer cells - outlining how cancer cells hijack specific pathways for uncontrolled proliferation - will lead to more efficient ways to fight it.

New EU-funded project provides insight into how the brain develops

The human brain is comprised of billions of different types of cells. These cells are then organized into sophisticated networks, each of which determines a specific function of the brain. But how do the neurons, or nerve cells that form these networks, find the right network? And what happens when they don’t?

Scientists support original theory about pancreas regeneration

A contentious debate among diabetes researchers has surrounded the regeneration of pancreatic insulin-producing cells: not if these cells regenerate, but rather how.

New diagnostic tool enables speedy diagnosis of bacterial infections

Using a small and inexpensive biosensor, researchers at UBC Okanagan, in collaboration with the University of Calgary, have built a diagnostic tool that provides health care practitioners almost instant diagnosis of a bacterial infection.

Scientists visualize action of immune cells in response to cancer cell proliferation

As tumors develop, they evolve genetically. How does the immune system act when faced with tumor cells? How does it exert pressure on the genetic diversity of cancer cells? Scientists from the Institut Pasteur and Inserm used in vivo video techniques and cell-specific staining to visualize the action of immune cells in response to the proliferation of cancer cells.
