The amyloid hypothesis in Alzheimer disease (AD) considers amyloid β peptide (Aβ) deposition causative in triggering down-stream events like neurofibrillary tangles, cell loss, vascular damage and memory decline. In the past years N-truncated Aβ peptides especially N-truncated pyroglutamate AβpE3-42 have been extensively studied. Together with full-length Aβ1-42 and Aβ1-40, N-truncated AβpE3-42 and Aβ4-42 are major variants in AD brain. Although Aβ4-42 has been known for a much longer time, there is a lack of studies addressing the question whether AβpE3-42 or Aβ4-42 may precede the other in Alzheimer's disease pathology.
