Photo: Pink lump of cartilage [28/01/2016] In an effort to develop a method for cartilage tissue engineering, researchers at Umeå University in Sweden successfully used cartilage cells from cow knee joints. By creating a successful method with conditions conducive to growing healthy cartilage tissue, the findings could help lead to a new treatment cure for osteoarthritis using stem cell-based tissue engineering.Cells from cow knee joints to grow new cartilage tissue - Read more

Graphic: Polymerase [22/01/2016] Scientists at the Helmholtz Zentrum München, working with colleagues from the Ludwig-Maximilians-Universität München, have developed a method for the thorough analysis of protein modifications. They mapped the phosphorylation sites of the RNA polymerase II enzyme, which is responsible for expressing our genes. The results have now been published in the "Molecular Cell" scientific journal.Exact pol(e) position - Read more

Graphic: Kinesin Mutants [21/01/2016] Researchers at the RIKEN Brain Science Institute in Japan have discovered how to reverse the abnormal axonal development characteristic of CFEOM3, a congenital disease that affects the muscles that control eye movements. Published in "Nature Communications", the work shows how creating a specific mutation rescued abnormal axonal growth in the developing mouse brain.Thwarting abnormal neural development with a new mutation - Read more

Biophysicists measure "wriggle" of red blood cells

Graphic: Brown monitoring grid with directional arrows [20/01/2016] For the first time and using physical methods, scientists have demonstrated how red blood cells move. They recognized that fast molecules in the vicinity make the cell membrane in the blood cells wriggle but that the cells themselves also become active when they have enough reaction time. The study was published in "Nature Physics".Biophysicists measure "wriggle" of red blood cells - Read more

Important Regulator of Immune System Decoded

Graphic: Cross section through a plasma cell [20/01/2016] Plasma cells play a key role in our immune system. Now scientists at the Research Institute of Molecular Pathology (IMP) in Vienna, Austria, and at the Walter and Eliza Hall Institute (WEHI) in Melbourne, Australia, succeeded in characterizing a central regulator of plasma cell function. The results of both teams are published in two back-to-back papers in "Nature Immunology" today.Important Regulator of Immune System Decoded - Read more

Atrial fibrillation ablation: Gap-AF trial published

Photo: electrocardiogram [18/01/2016] Using catheter ablation to create complete linear lesions around pulmonary veins, proved more effective than the creation of incomplete lesions in preventing recurrence of atrial fibrillation (AF). This is the result of Gap-AF – AFNET 1, the first controlled clinical trial that compared directly the two ablation strategies in patients with paroxysmal atrial fibrillation.Atrial fibrillation ablation: Gap-AF trial published - Read more

Lung cell acting as sensor

Photo: pulmonary neuroendocrine cells in red [14/01/2016] An uncommon and little-studied type of cell in the lungs has been found to act like a sensor, linking the pulmonary and central nervous systems to regulate immune response in reaction to environmental cues.Lung cell acting as sensor - Read more

The cellular trash bag

Photo: Atg9-vesicles [14/01/2016] In autophagy, the process responsible for recycling waste in cells, molecular waste bags are produced. As now reported scientists have identified a molecular glue that sticks small lipid vesicles, the building blocks for the waste bags, together. Autophagy helps cancer cells survive chemotherapy treatment. The cellular trash bag - Read more

Why nerve cells die

( Source: MEDICA.de )

Photo: protein aggregates under the microscope [13/01/2016] For many years researchers have observed protein deposits, also called aggregates, in the brains of patients with Alzheimer’s or Huntington’s disease. These aggregates are suspected to contribute to the death of nerve cells. Researchers from the Max Planck Institute of Biochemistry in Martinsried have now shown that the location of aggregates influences the survival of cells. Why nerve cells die - Read more
