In research published in the Journal of Cell Biology, scientists from the RIKEN Brain Science Institute in Japan have made important steps toward understanding how dynein—a "molecular motor"—walks along tube-like structures ...
(Phys.org) —Even the mildest form of a traumatic brain injury, better known as a concussion, can deal permanent, irreparable damage. Now, an interdisciplinary team of researchers at the University of Pennsylvania is using ...
(Phys.org)—The plasma membranes that give cells their shapes are typically upheld by linear meshworks of the protein actin. In contrast, Howard Hughes Medical Institute scientists have now discovered that periodic ring-shaped ...
Over the past several years, Rong Li, Ph.D., at the Stowers Institute for Medical Research has been making crucial discoveries about the development of cell polarity—the process by which one side of a cell becomes different ...
Smithsonian researchers report that the brains of tiny spiders are so large that they fill their body cavities and overflow into their legs. As part of ongoing research to understand how miniaturization affects brain size ...
In what they are calling a new direction in the study of Alzheimer's disease, UC Santa Barbara scientists have made an important finding about what happens to brain cells that are destroyed in Alzheimer's disease and related ...
(PhysOrg.com) -- Scientists have long sought the ability to regenerate nerve cells, or neurons, which could offer a new way to treat spinal-cord damage as well as neurological diseases such as Alzheimer's or Parkinson's. ...
Tiny, toxic protein particles severely disrupt neurotransmission and inhibit delivery of key proteins in Alzheimer's disease, two separate studies by Marine Biological Laboratory (MBL) researchers have found.
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular ...
A discovery in a transparent roundworm has brought scientists one step closer to understanding nerve degeneration.
