While the word “mutation” may conjure up alarming notions, a mutation in brain immune cells serves a positive role in protecting people against Alzheimer’s disease. Now University of California, Irvine biologists have discovered the mechanisms behind this crucial process. Their paper appears in the journal Alzheimer’s and Dementia.
The investigation centered on a variant of the PLCG2 gene, which makes the instructions for producing an enzyme important to brain immune cells called microglia. “Recently the mutation, which is known as P522R, was shown to lower the risk of developing late-onset Alzheimer’s,” said Hayk Davtyan, Ph.D., senior…
