Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

1.9K
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...

Extracellular Matrix01:26

Extracellular Matrix

6.2K
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

5.7K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

2.9K
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.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

3.7K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. 
Anchoring junctions mechanically attach a cell to the...

Area of Science:

  • Cell biology
  • Biophysics
  • Pathology

Background:

  • Cells constantly sense and respond to mechanical and biochemical signals from their environment.
  • Mechanotransduction, the conversion of mechanical force into biochemical signals, is crucial for cell functions like differentiation and migration.
  • Aberrant mechanical cues or cellular misinterpretation can lead to various diseases.

Purpose of the Study:

  • To discuss the significant impact of cell and tissue mechanics on maintaining tissue homeostasis.
  • To explore the role of mechanical forces in the development and progression of diseases.
  • To highlight the involvement of mechanotransduction in brain development, homeostasis, neural degeneration, and brain cancer.

Main Methods:

  • This commentary synthesizes current research on mechanotransduction and its role in health and disease.
  • It reviews how changes in cell and tissue mechanics influence biological processes.
  • Focuses on examples within the brain, including development, degeneration, and cancer.

Main Results:

  • Altered mechanical cues, such as increased interstitial pressure or matrix stiffening, can disrupt normal cellular functions.
  • Dysregulation of cellular contractility and mechanosignaling contributes to disease states like cardiovascular disease, fibrosis, and cancer.
  • Cell and tissue mechanics play a critical role in brain development, maintaining neural homeostasis, and driving neurodegeneration and brain cancer.

Conclusions:

  • Cell and tissue mechanics are fundamental to maintaining organismal health and orchestrating development.
  • Disruptions in mechanotransduction and abnormal mechanical forces are implicated in the pathogenesis and progression of numerous diseases.
  • Understanding these mechanical principles is vital for developing new therapeutic strategies for conditions affecting the brain and other tissues.
