Dysfunction of the neurovascular unit in brain aging
Journal of Biomedical Research
|May 17, 2023
Summary
Aging impairs the neurovascular unit (NVU), increasing susceptibility to neurodegenerative diseases like Alzheimer's and Parkinson's. Maintaining NVU health may delay aging and disease progression.
Area of Science:
- Neuroscience
- Gerontology
- Vascular Biology
Background:
- The neurovascular unit (NVU) is crucial for neurovascular coupling.
- NVU impairment is linked to neurodegenerative diseases, including Alzheimer's and Parkinson's disease.
- Aging is characterized by functional decline and increased disease susceptibility.
Purpose of the Study:
- To review the fundamentals of the NVU.
- To discuss the impact of aging on the NVU.
- To explore mechanisms linking NVU dysfunction to neurodegeneration and potential therapeutic strategies.
Main Methods:
- Literature review of studies on the neurovascular unit.
- Analysis of aging effects on NVU components and function.
- Synthesis of current research on neurodegenerative disease mechanisms related to NVU.
Main Results:
- Aging negatively affects the structural and functional integrity of the NVU.
- Specific mechanisms contributing to NVU susceptibility in aging are identified.
- The review highlights the connection between NVU health and age-related neurodegenerative diseases.
Conclusions:
- The NVU plays a critical role in brain health during aging.
- Understanding NVU aging is key to developing interventions for neurodegenerative diseases.
- Strategies to maintain NVU integrity may offer therapeutic benefits for aging and related disorders.

01:19The Effect of Aging on Tissues
2.2K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:15Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

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.
