Fyn, a potential target for Alzheimer's disease

Area of Science:

• Neuroscience
• Molecular Biology
• Biochemistry

Background:

• Alzheimer's disease (AD) is a neurodegenerative disorder marked by amyloid-beta (Aβ) plaques and neurofibrillary tangles.
• The precise molecular mechanisms underlying AD pathogenesis remain incompletely understood.
• Emerging evidence implicates Fyn, a Src family kinase, in AD development.

Purpose of the Study:

• To explore the role of Fyn kinase in Alzheimer's disease (AD) pathogenesis.
• To investigate Fyn's involvement in synaptic plasticity, Aβ production, and tau phosphorylation.
• To identify potential therapeutic strategies targeting Fyn for AD treatment.

Main Methods:

• Literature review of studies investigating Fyn kinase in relation to AD.
• Analysis of Fyn's known functions in synaptic plasticity, Aβ metabolism, and tau pathology.
• Synthesis of current evidence on Fyn's contribution to AD-related neurotoxicity.

Main Results:

• Fyn kinase is implicated in regulating synaptic plasticity, a key process for learning and memory.
• Fyn influences amyloid-beta (Aβ) production and mediates Aβ-induced synaptic deficits and neurotoxicity.
• Fyn promotes tyrosine phosphorylation of tau, a hallmark of AD.

Conclusions:

• Alterations in Fyn kinase activity are potentially significant contributors to Alzheimer's disease (AD) pathogenesis.
• Understanding Fyn's precise cellular and molecular roles in AD is crucial for advancing treatment strategies.
• Targeting Fyn kinase may offer novel pharmacological approaches for managing AD.
