Alzheimer's Disease (AD) In Vitro Assay Services
The course of Alzheimer's disease (AD) is an irreversible process, and so far, there are no effective drugs and methods to treat it. Therefore, early diagnosis is crucial for AD treatment. At present, the main research focuses on the β-amyloid (Aβ) and tau protein markers in cerebrospinal fluid (CSF). After decades of accumulation, Creative Biolabs has established an advanced platform for Aβ and tau detection. We are committed to providing professional AD in vitro testing services to customers around the world.
Introduction to AD
AD is the most common disease among the elderly and is defined as a slowly progressive neurodegenerative disease. Clinical symptoms include progressive memory loss, language impairment, impaired executive function, and altered emotional behavior. AD is thought to be associated with a variety of risk factors, such as genetic factors, increasing age, poisoning, infection, head injury, pulmonary and circulatory abnormalities, and environmental factors.

AD Pathogenesis
The pathology of AD mainly involves two proteins: Aβ and tau. Aβ is the main component of senile plaques and tau is the main component of neurofibrillary tangles.
- Aβ and AD
Aβ peptide is a major component of senile plaques in AD pathogenesis. Aβ aggregates assemble from Aβ monomers into various unstable oligomers, which then further aggregate to form pliable fibrils and finally insoluble fibrillar assemblies. Aβ is closely associated with neuronal and synaptic dysfunction during AD progression. In addition, studies have shown that Aβ oligomers are neurotoxic.

- Tau and AD
There are diverse forms of post-translational modifications (PTMs) on tau, such as phosphorylation, methylation, and glycosylation. Alterations in tau PTM, as well as tau aggregate deposition, were observed in AD. Elevated levels of phosphorylated tau were detected in the CSF of potential AD patients and correlated with cognitive impairment, suggesting that Tau hyperphosphorylation acted as an early event in AD pathogenesis. Therefore, phosphorylated tau in CSF is considered as a potential biomarker in AD diagnosis.
