Both Brain And Muscle Require Having The Protein LRP4 For Strong Communication
2012-07-11 20:39:24

Communication between the brain and muscle must be strong for us to eat, breathe or walk. Now scientists have found that a protein known to be on the surface of muscle cells must be present in both tissues to ensure the conversation is robust. Scientists at the Medical College of Georgia at Georgia Health Sciences University have shown that without LRP4 in muscle cells and neurons, communication between the two cells types is inefficient and short-lived. Problems with the protein appear...

Some unusual alliances are necessary for you to wiggle your fingers, researchers report. Understanding those relationships should enable better treatment of neuromuscular diseases, such as myasthenia gravis, which prevent muscles from taking orders from your brain, said Dr. Lin Mei, Director of the Institute of Molecular Medicine and Genetics at Georgia Health Sciences University. During development, neurons in the spinal cord reach out to muscle fibers to form a direct line of...

Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, until now no one knew which purpose nestin serves in a cell. In a study published in the Jan. 30, 2011, advance online edition of Nature Neuroscience, Salk Institute of Biological Studies investigators led by Kuo-Fen Lee, PhD., show that nestin has reason for being in a completely...


Word of the Day
endocarp
