S-Nitrosylation in Alzheimer's disease

Area of Science:

• Biochemistry
• Neuroscience
• Cell Biology

Background:

• S-nitrosylation is a redox-mediated posttranslational modification involving nitric oxide (NO) binding to cysteine residues, forming nitrosothiols (SNOs).
• This reversible process normally functions in cellular signaling, similar to protein phosphorylation.
• Aberrant S-nitrosylation is implicated in protein misfolding, mitochondrial dysfunction, synaptic damage, and apoptosis, key features in Alzheimer's disease (AD) pathogenesis.

Purpose of the Study:

• To review recent findings on key S-nitrosylated proteins in Alzheimer's disease (AD) pathogenesis.
• To discuss the impact of SNO proteins on AD progression.
• To explore therapeutic strategies targeting S-nitrosylated proteins for AD treatment.

Main Methods:

• Literature review of recent findings on S-nitrosylation in Alzheimer's disease.
• Analysis of the role of SNO proteins in AD progression.
• Examination of therapeutic approaches targeting S-nitrosylated proteins.

Main Results:

• Aberrant S-nitrosylation is linked to critical pathological events in AD, including mitochondrial dysfunction and synaptic loss.
• Specific S-nitrosylated proteins play crucial roles in the progression of Alzheimer's disease.
• Interference with S-nitrosylation has shown protective effects in AD animal models.

Conclusions:

• S-nitrosylation is a significant factor in Alzheimer's disease pathogenesis.
• Targeting S-nitrosylated proteins offers a promising therapeutic avenue for AD.
• Further research is needed to overcome challenges in developing S-nitrosylation-based therapies for AD.
