Failure to destroy toxic protein -- not buildup of protein itself -- contributes to Huntington's disease Posted: 21 Jul 2013 01:17 PM PDT Recycling is not only good for the environment, it's good for the brain. A study using rat cells indicates that quickly clearing out defective proteins in the brain may prevent loss of brain cells.

Multiple sclerosis research could help repair damage affecting nerves Posted: 21 Jul 2013 01:17 PM PDT Multiple sclerosis treatments that repair damage to the brain could be developed thanks to new research. A study has shed light on how cells are able to regenerate protective sheaths around nerve fibers in the brain.

A first in front-line immunity research Posted: 21 Jul 2013 01:17 PM PDT Researchers have gained new insight into the early stages of our immune response, providing novel pathways to develop treatments for diseases from multiple sclerosis to cancer.

Common stem cell in heart and lung development explains adaption for life on land Posted: 21 Jul 2013 01:17 PM PDT Biologists have known that the co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to life outside of water. Researchers show that the pulmonary vasculature develops even in the absence of the lung. Mice in which lung development is inhibited still have pulmonary blood vessels, which revealed to the researchers that cardiac progenitors, or stem cells, are essential for cardiopulmonary co-development.

A bad alliance: Rare immune cells promote food-induced allergic inflammation in the esophagus Posted: 21 Jul 2013 01:17 PM PDT Until recently, how EoE, a food allergy-associated disease, developed was unclear, but a new study shows that a type of rare immune cell and specific reactions to allergenic foods team up -- in a bad way. This association does point to new ways to possibly treat inflammation associated with EoE.

Flip of mitotic spindle has disastrous consequences for epithelial cells Posted: 21 Jul 2013 01:14 PM PDT Investigators have used genetics and live cell imaging to illuminate molecular mechanisms that position the cell division machinery in growing tissues.

Sex chromosome shocker: The 'female' X a key contributor to sperm production Posted: 21 Jul 2013 01:13 PM PDT Painstaking new analysis of the genetic sequence of the X chromosome -— long perceived as the "female" counterpart to the male-associated Y chromosome -— reveals that large portions of the X have evolved to play a specialized role in sperm production.

Drug research: New technique shows if drugs have reached intended target Posted: 18 Jul 2013 07:14 AM PDT The search for new drugs, including those for cancer, is set to speed up thanks to a new research technique which could tell if drugs had reached their intended target.
