Summary
Neurodegenerative diseases impair mitochondrial function and energy metabolism. Therapies targeting these pathways show varied success, necessitating further research into underlying mechanisms for Alzheimer
Area of Science:
- Neuroscience
- Biochemistry
- Pharmacology
Background:
- Mitochondrial dysfunction and impaired energy metabolism are hallmarks of neurodegenerative diseases like Alzheimer's, Parkinson's, and ALS.
- These deficits are observed both within the central nervous system and systemically.
Purpose of the Study:
- To review therapies impacting mitochondrial energy metabolism for neurodegenerative diseases.
- Focus on pre-clinical and clinical studies published up to May 2016.
Main Methods:
- Literature review of therapeutic interventions.
- Analysis of studies targeting mitochondrial function and energy pathways.
Main Results:
- Mitochondrial dysfunction is a key driver of neurodegenerative disease progression.
- Therapeutic initiatives targeting these pathways have yielded mixed results.
Conclusions:
- Current treatments for neurodegenerative diseases affecting mitochondrial energy metabolism have shown variable efficacy.
- Further investigation into the fundamental mechanisms of mitochondrial dysfunction and bioenergetic failure is crucial for developing effective therapies.

Electron Transport Chain: Complex I and II
19.3K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.

Drugs Affecting Neurotransmitter Synthesis
2.4K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

Alzheimer's Disease: Treatment
1.1K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Mitochondria
21.1K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Mitochondrial Membranes
17.6K
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Parkinson's Disease: Overview
2.3K
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...
