Summary
Early communication problems between mitochondria and endoplasmic reticulum (ER) are linked to Alzheimer's disease (AD) hallmarks. Understanding these disruptions may reveal new therapeutic targets for this common neurodegenerative disorder.
Area of Science:
- Neuroscience
- Cell Biology
- Biochemistry
Background:
- Alzheimer's disease (AD) is a prevalent neurodegenerative disorder affecting the elderly, with no current cure.
- The precise mechanisms driving neuronal damage and cognitive decline in AD remain largely unknown.
- Emerging evidence suggests early disruptions in mitochondria-endoplasmic reticulum (ER) communication are implicated in AD pathogenesis.
Purpose of the Study:
- To review recent findings on the role of ER-mitochondria coupling alterations in Alzheimer's disease.
- To connect changes in organelle communication with established hallmarks of AD.
Main Methods:
- Literature review of recent studies focusing on ER-mitochondria crosstalk in AD models.
- Analysis of findings linking specific alterations in ER-mitochondria coupling to AD pathology.
Main Results:
- Accumulating evidence points to early perturbations in the communication between mitochondria and the ER in AD.
- Alterations in ER-mitochondria coupling are associated with key pathological features characteristic of Alzheimer's disease.
Conclusions:
- Dysfunctional ER-mitochondria communication represents a significant factor in the development of Alzheimer's disease.
- Further research into these early cellular disruptions may uncover novel therapeutic strategies for AD.

01:19Translocation of Proteins into the Mitochondria
3.3K
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

01:26Alzheimer's Disease: Overview
669
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

01:28The Inner Mitochondrial Membrane
3.7K
The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria. In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

01:37Mitochondria
15.0K
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,...

262
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...

12.4K
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,...
