Finally, considering the correlation between neuroinflammation, oxidative stress, and AD [34,35], after UFP exposure, we analyzed proteins involved in amyloidogenic processing (amyloid precursor protein (APP), phosphorylated APP on threonine 668 (p-APP Thr668), and beta-secretase 1 (BACE1)) as markers of neurodegeneration. The gene discussed is BACE1; the disease is Alzheimer disease.
