Scientists step closer to finding cause of multiple sclerosis

As they find out more about the cell biology of multiple sclerosis, scientists are gradually unraveling the mysteries of the disease, although the exact causes are still unclear. Now, a new study continues this progress with a significant discovery about a new cellular mechanism. It suggests that high levels of the protein Rab32 disrupt key communications involving mitochondria. The disruption causes these "cellular batteries" to misbehave, leading to the toxic effects seen in the brain cells of people with multiple sclerosis. MS researchers are becoming increasingly interested in mitochondria, which…
