Alzheimer's disease: How amyloid aggregates alter neuronal function

While the harmful effects of amyloid peptide aggregates observed in Alzheimer's disease are well established, the mechanism through which they act on brain cells remains ill-defined. Researchers from CNRS and universite de ...

Stem cells may be the key to staying strong in old age

University of Rochester Medical Center researchers have discovered that loss of muscle stem cells is the main driving force behind muscle decline in old age in mice. Their finding challenges the current prevailing theory ...

Ophthalmology

New insight into eye diseases

Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, ...

New clues to halting nerve degeneration

A discovery into the mechanisms which lead to degeneration and loss of communication among neuron cells - the cells controlling function in the brain and nervous system - could potentially lead to future therapies for neurodegenerative ...
