Insights

Alzheimer's disease research needs new targets beyond amyloid. Exploring inflammation, tau, and microbiome may offer effective Alzheimer's therapeutics.

Area of Science:

  • Neuroscience
  • Pharmacology
  • Gerontology

Background:

  • Decades of Alzheimer's disease (AD) research centered on amyloid pathology.
  • Amyloid-targeting therapies have shown limited success in preventing cognitive decline.
  • The lack of approved disease-modifying agents necessitates exploring alternative therapeutic strategies for AD.

Framework:

  • The symposium highlighted the need for timely intervention targeting specific AD pathologies.
  • Focus shifted towards understanding AD as a complex disease with multiple contributing factors.
  • Exploration of novel therapeutic targets beyond amyloid is crucial for effective AD treatment.

Implementation:

  • Preclinical and early clinical studies are investigating targets such as neuroinflammation, tau protein, vascular health, and the gut microbiome.
  • Symposium discussions emphasized the importance of a multi-faceted approach to AD drug development.
  • Presentations covered emerging research on non-amyloid targets for Alzheimer's disease therapeutics.

Implications:

  • Identifying and validating alternative targets could lead to the first approved disease-modifying therapies for Alzheimer's.
  • A paradigm shift in AD research towards diverse pathologies may accelerate therapeutic breakthroughs.
  • Future AD treatments may involve combination therapies targeting multiple disease pathways.

Alzheimer's Disease: Treatment

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...
