It was long thought that the immune system does not have much of an effect on Alzheimer’s disease.However, a new study revealed key immune cells located outside of the brain actually help rid the brain of the plaques that build up and trigger the disease.A team of scientists from the University of California, Irvine genetically modified a group of mice with Alzheimer’s to lack those immune cells – B-cells, T-cells and NK-cells.
They were found to have a far larger accumulation of Alzheimer’s plaque than mice whose immune systems were intact.
This finding paves the way for new techniques to identify or treat individuals at risk of the disease.
