Nervous Tissue: Glial Cells

6.4K
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial...

Neurogenesis and Regeneration of Nervous Tissue

1.5K
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...

Neural Regulation

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.

Chemical Synapses01:26

Chemical Synapses

11.1K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Area of Science:

  • Neuroscience
  • Genetics
  • Cell Biology

Background:

  • Motor neuron disorders, including Amyotrophic Lateral Sclerosis (ALS) and Spinal Muscular Atrophy (SMA), are severe, often fatal conditions with limited treatment options.
  • While motor neuron loss is a hallmark, pathological changes in surrounding glial cells are increasingly recognized as significant contributors to neurodegeneration.
  • Understanding the precise mechanisms driving motor neuron degeneration is crucial for developing effective therapies.

Purpose of the Study:

  • To explore the role of astrocytes in the pathogenesis of ALS and SMA.
  • To highlight the contribution of glial dysfunction to the toxic central nervous system environment in these diseases.
  • To evaluate glial cells as a potential therapeutic target for motor neuron disorders.

Main Methods:

  • Review and synthesis of existing research on ALS and SMA pathogenesis.
  • Focused discussion on the specific involvement of astrocytes in disease mechanisms.
  • Analysis of findings related to glial-neuronal interactions and their perturbation.

Main Results:

  • Both ALS and SMA involve pathological lesions in neighboring glia, not just motor neurons.
  • Astrocyte dysfunction contributes to a toxic environment within the central nervous system.
  • Perturbations in glial-neuronal interplay are evident in these motor neuron diseases.

Conclusions:

  • Astrocytes are key players in the pathogenesis of ALS and SMA.
  • The glial contribution to motor neuron disorders necessitates a re-evaluation of therapeutic strategies.
  • Targeting astrocytes presents a novel and promising therapeutic avenue for treating debilitating motor neuron diseases.
