AbstractAlzheimer's disease (AD) is characterized by memory loss, intracellular neurofibrillary tangles, and extracellular plaque deposits composed of beta-amyloid (A beta). Previous reports showed that naturally occurring autoantibodies, such as intravenous immunoglobulin (IVIG), benefited patients with moderate-stage AD who carried an APOE-epsilon 4 allele. However, the mechanism underlying the role of IVIG remains unclear. In this study, we identified naturally occurring autoantibodies against A beta oligomers (NAbs-A beta o), which were purified by A beta 42 oligomer or Cibacron Blue affinity chromatography from IVIG and termed as Oli-NAbs and Blue-NAbs, respectively. Oli-NAbs and Blue-NAbs recognized A beta 42 oligomers or both A beta 40 and 42 oligomers, differently. Both antibodies inhibited A beta 42 aggregation and attenuated A beta 42-induced cytotoxicity. Compared with vehicles, Oli-NAbs, Blue-NAbs and IVIG significantly improved the memory and cognition, and reduced the soluble and oligomeric A beta levels in APPswe/PS1dE9 transgenic mice. Further investigation showed that Blue-NAbs at increased doses effectively decreased plaque burden and insoluble A beta levels, whereas Oli-NAbs significantly declined the microgliosis and astrogliosis, as well as the production of proinflammatory cytokines in vivo. Therefore, high levels of these antibodies against oligomeric A beta 40 or A beta 42 were required, correspondingly, to achieve the optimal effect. NAbs-A beta o could be condensed to a high concentration by affinity chromatography and its isolation from IVIG may not interfere with the normal function of conventional IVIG as its concentration is very low. Thus, the isolated NAbs-A beta o as an extra product of plasma required low cost and the enriched NAbs-A beta o may be more feasible than IVIG for the treatment of AD. (C) 2016 Elsevier Ltd.
