Summary
The proteostasis network maintains protein balance, but declines with age, leading to alpha-synuclein (aSyn) buildup in Parkinson's disease (PD). This chapter reviews aSyn's toxic effects and potential therapeutic targets for PD.
Area of Science:
- Neuroscience
- Molecular Biology
- Cellular Biology
Background:
- The proteostasis network regulates protein homeostasis, crucial for preventing aggregation.
- Misfolded alpha-synuclein (aSyn) accumulation drives Parkinson's disease (PD) and synucleinopathies.
- Aging impairs proteostasis, reducing clearance of damaged proteins like aSyn.
Purpose of the Study:
- To review findings on aSyn accumulation and degradation in PD.
- To discuss the impact of toxic aSyn on proteostasis.
- To identify potential therapeutic targets for PD.
Main Methods:
- Literature review of proteostasis and aSyn.
- Analysis of aSyn aggregation and clearance mechanisms.
- Identification of pathways affected by toxic aSyn.
Main Results:
- Aging-related decline in proteostasis exacerbates aSyn accumulation.
- Compromised aSyn clearance contributes significantly to PD progression.
- Toxic aSyn species disrupt cellular proteostasis networks.
Conclusions:
- Proteostasis decline is a key factor in PD pathogenesis.
- Targeting aSyn degradation pathways offers therapeutic potential for PD.
- Understanding aSyn-proteostasis interactions is vital for developing PD treatments.

1.6K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
