Alzheimer's Disease Drug Screening Service

As a progressive neurodegenerative disease, Alzheimer's disease (AD) manifests itself as cognitive impairment, progressive memory loss, and neurodegeneration mainly affecting people over 65 years of age. AD is closely related to age, characterized by the prevalence of extracellular Aβ plaques and intracellular neurofibrillary tangles. After years of extensive research, the underlying pathological molecular mechanisms of AD remain unclear. C. elegans is an excellent model organism that can be used to study AD. CD BioSciences provides AD drug screening services to passionate researchers around the globe by utilizing a high throughput screening platform based on C. elegans.

C. elegans for Alzheimer's Disease Research

Alzheimer's disease (AD) is a chronic and irreversible neurodegenerative disorder whose pathology is clearly indicated by a large accumulation of amyloid-β (Aβ) in the brain. Currently, only the symptoms caused by AD can be treated, not cured. Although various in vitro and cell-based models have been proposed for high-throughput drug screening for potential therapeutic benefits in protein misfolding disorders. Due to the disease manifests on several scales, including molecular, cellular, and organismal, it is difficult within the organismal phenotype to replicate and exploit for screening in vitro. Additionally, while mammalian models can be used for in vivo screening of new compounds, the time and effort required when screening candidate compounds in large numbers is prohibitive. C. elegans provides a convenient in vivo system for AD drug screening, which can be used to check for toxicity outcomes of overexpression of proteins and peptides susceptible to pathologic misfolding, and for the discovery of proteins that can be protected against misfolding of protein compounds.
