Alzheimer's Protein tagged posts

Of all the known genetic risk factors for late-onset Alzheimer’s disease, the strongest is a gene for the protein called ApoE4. People with one copy of this gene are 3.5 times more likely, on average, to develop Alzheimer’s than others, and those with two copies face a 12-fold increased risk. However, exactly how ApoE4 boosts the risk of Alzheimer’s remains unclear.

Multiple types of cells in the brain make ApoE4—some of it is produced by neurons, but other brain cells called glia make it in higher quantities. For that reason, most prior research on this protein has focused on ApoE4 from glia.

Now, researchers at G...
