Alzheimer disease

Host immune defence, amyloid-β peptide and Alzheimer disease

Nature Reviews Neurology volume 12, pages 433434 (2016) | Download Citation

A recent study demonstrates that amyloid-β (Aβ) can function as an antimicrobial peptide, and additional data show that bacteria and yeast can seed Aβ deposition into amyloid. These data suggest a complex interplay between the normal function of Aβ, its accumulation in the brain, and host immune defence.
