1 Jun 1990 | Journal: | Science, 248 (4959), 1122-4 | Abstract: | The amyloid beta peptide (A beta P) is a small fragment of the much larger, broadly distributed amyloid precursor protein (APP). Abundant A beta P deposition in the brains of patients with Alzheimer’s disease suggests that altered APP processing may represent a key pathogenic event. Direct protein structural analyses showed that constitutive processing in human embryonic kidney 293 cells cleaves APP in the interior of the A beta P, thus preventing A beta P deposition. A deficiency of this processing event may ultimately prove to be the etiological event in Alzheimer’s disease that gives rise to senile plaque formation. | Source: | PubMed, pmid2111583 | Services: | Forum | Review | Favorites |
