IL1B and Alzheimer disease: EVs have also shown to play a role in neurodegenerative diseases, such as transportation of neurotoxic amyloid‐beta in Alzheimer's disease, increase in pro‐inflammatory cargoes such as interleukin 1 beta (IL‐1β) due to neuroinflammation and propagation of the disease‐associated prion protein, PrPSc which can be found on the surface of EVs derived from prion‐infected cells [40, 41, 42, 43, 44].
