Common Cause Of All ALS Forms Identified - Seen As A Major ALS Breakthrough published
Mon, 22 Aug 2011 10:00:00 PST
All forms of ALS are caused by a protein recycling system in the neurons of the spinal cord and brain that breaks down. For neurons to function properly, they rely on the effective recycling of the protein building blocks in cells - they need to be removed and reprocessed. In ALS, when the recycling system is broken, the cells cannot repair themselves, resulting in serious damage...
