Stem cells from the bone marrow of adults may be as flexible as embryonic stem cells, according a study in the current issue of Cell. Researchers at Yale, New York University, and Johns Hopkins found that these cells...
Two reports in tomorrow's Science add to a growing body of evidence that glial cells play more than a "housekeeping" role and are essential for neuronal signalling...
In a prime example of what science can accomplish in the "post-genomic" era, researchers have pieced together the functions of a variety of genes involved in a yeast metabolism pathway...
A closer look at mitochondria in Alzheimer's disease
confirms that oxidative damage to these cellular power plants is a central feature of the disease, according to a report in the May 1 issue of the Journal of Neuroscience...
A major challenge for achieving nerve regeneration following an injury to the adult brain and spine is the presence of numerous proteins that block the growth of axons across the injury site...
Researchers from France reported success in synthesizing novel compounds that specifically target γ-secretase cleavage of amyloid-β (Aβ) peptide, without affecting the enzyme's cleavage of other substrates...
Stem cells from mouse bone marrow can help repair muscle killed in heart attacks, Piero Anversa and
his team at New York Medical College, New York, and colleagues, show in [the 5 April issue of] Nature...
A team at Dartmouth College, New Hampshire, has developed a brain-image repository that will make it possible for scientists to freely share fMRI data with colleagues worldwide...
The abnormal form of the protein huntingtin may exert
its toxic effects on neurons in Huntington's disease by interfering with a protein essential for gene transcription, according to a study published in this week's issue of Science...
It is now generally accepted that new neurons are generated in the adult mammalian brain,
but until now it has been unclear whether or not these neurons are essential for memory formation...
A British and German team has made the surprising discovery that the cell's mitochondria can export peptides into their surrounding environments. Much is known about how mitochondria import proteins, but the
role of this unexpected export mechanism...
Understanding the mechanisms regulating brain wiring has until now relied on biochemical purification approaches in vertebrates and genetic approaches in invertebrates to identify molecular clues. This week...
This week Peter Chien and Jonathan Weissman of the University of California, San Francisco, explain how they used two species of yeast (and an artificial yeast prion protein to investigate how prions jump the species barrier...
