Immunotherapeutic Approaches for Alzheimer’s Disease

Abstract

Alzheimer's disease (AD) is the most prevalent form of dementia worldwide and is an emerging global epidemic. It is characterized by an imbalance between production and clearance of amyloid β (Aβ) and tau proteins. Oligomeric forms of Aβ and tau are believed to be the most toxic. Dramatic results from AD animal models showed great promise for active and passive immune therapies targeting Aβ. However, there is very limited evidence in human studies of the clinical benefits from these approaches. Immunotherapies targeting only tau pathology have had some success but are limited so far to mouse models. The majority of current methods is based on immunological targeting of a self-protein; hence, benefits need to be balanced against risks of stimulating excessive autoimmune toxic inflammation. For greater efficacy the next generation of vaccines needs to focus more on concurrently targeting all the intermediate toxic conformers of oligomeric Aβ and tau species.

  • Humanized antibodies targeting misfolded proteins such as amyloid-beta have been developed and are being tested in clinical trials.

    “Humanized antibodies that target misfolded proteins, such as Aβ, have been developed and are currently being tested in clinical trials (188, 189).”
  • Passive and active immunization are the two key immunotherapeutic methods for promoting Aβ clearance that are presently under investigation in various phases of analyses.

    “Passive and active immunization are the 2 key immunotherapeutic methods for promoting Aβ clearance that are presently under investigation in various phases of analyses (Wisniewski et al., 2015).”

  • Immunotherapeutic approaches have dominated in the past 15 years with negative results until now.

    “Immunotherapeutic approaches have dominated in the past 15 years with negative results until now.”
  • Antigen-presenting cells present immunogens to B cells; use of Aβ or ptau peptides produces antibodies to Aβ or ptau epitopes, respectively; use of pBri produces antibodies to both Aβ and ptau epitopes.

    “Antigen-presenting cells present the immunogens to B cells. Use of Ab or ptau peptides will produce antibodies to Ab or ptau epitopes, respectively. Use of pBri will produce antibodies to both Aβ and ptau epitopes.56”
  • Stimulation of innate immunity either by active or passive immunization also ameliorates the pathology of Alzheimer disease by promoting microglia and macrophage function.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
