Cuproptosis In Neurodegeneration plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Cuproptosis is a recently identified form of regulated cell death driven by copper-dependent proteotoxic stress. Discovered in 2022, this copper-induced cell death mechanism has emerged as a potentially important pathway in neurodegenerative diseases, where copper dyshomeostasis is frequently observed.
Unlike apoptosis (which is caspase-dependent) or ferroptosis (which is iron-dependent), cuproptosis is characterized by direct copper binding to lipoylated TCA cycle proteins, leading to proteotoxic stress and cell death. This mechanism may contribute to the neuronal loss observed in Alzheimer's disease (AD), Parkinson's disease (PD), and other neurodegenerative conditions.
| Protein | Role in Cuproptosis |
|---|---|
| DLAT | Dihydrolipoamide S-acetyltransferase, primary copper target |
| DLST | Dihydrolipoamide S-succinyltransferase, TCA cycle enzyme |
| PDH Complex | Pyruvate dehydrogenase, lipoylated protein target |
| CTR1 | High-affinity copper transporter (SLC31A1) |
| ATP7A/ATP7B | Copper-transporting ATPases |
| MT3 | Metallothionein-3, copper buffering |
The brain maintains strict copper homeostasis through:
Alzheimer's Disease:
Parkinson's Disease:
