Synaptic Dysfunction in Alzheimer's Disease: Aβ, Tau, and Epigenetic Alterations

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Alzheimer's disease (AD) is a neurodegenerative disorder causing memory loss.
• Synaptic dysfunction strongly correlates with cognitive decline in AD.
• Abnormal amyloid-beta (Aβ) and Tau aggregation are hallmarks of AD, contributing to synaptic loss.

Purpose of the Study:

• To explore the roles of Aβ, Tau, and epigenetic alterations in AD synaptic dysfunction.
• To investigate the specific contribution of non-coding RNAs (ncRNAs) to synaptic deficits in AD.
• To summarize recent findings on ncRNAs and synaptic pathologies in Alzheimer's disease.

Main Methods:

• Literature review and synthesis of existing research.
• Analysis of studies linking Aβ and Tau to synaptic function.
• Examination of research on epigenetic modifications, focusing on ncRNAs in AD.

Main Results:

• Aβ and Tau oligomers are implicated in synaptic loss in AD.
• Emerging evidence connects epigenetic dysregulation, including ncRNAs, to synaptic pathologies.
• ncRNAs show potential as key players in AD-related synaptic deficits.

Conclusions:

• Aβ, Tau, and ncRNAs are critical factors in AD synaptic dysfunction.
• Epigenetic mechanisms, especially ncRNAs, represent a promising area for understanding AD pathogenesis.
• Further research into ncRNAs could reveal novel therapeutic targets for Alzheimer's disease.
