Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis 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...
Nociception01:44

Nociception

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Cellular Injury I: Introduction01:00

Cellular Injury I: Introduction

Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...

This summary is machine-generated.

Central nervous system (CNS) neurons lack regeneration ability unlike peripheral nervous system (PNS) neurons. Injury signals, transported retrogradely, are crucial for stimulating CNS neuron intrinsic growth capacity for repair.

Area of Science:

  • Neuroscience
  • Cellular Biology
  • Regenerative Medicine

Background:

  • Peripheral nervous system (PNS) neurons exhibit robust self-repair post-injury.
  • Central nervous system (CNS) neurons lack spontaneous regeneration, a long-standing challenge.
  • Axonal regeneration is governed by environmental inhibitory cues and intrinsic neuronal growth capacity.

Purpose of the Study:

  • To investigate mechanisms stimulating intrinsic growth capacity in injured neurons.
  • To understand how CNS neurons receive injury information for regeneration.
  • To dissect injury-signaling pathways involved in neuronal repair.

Main Methods:

  • Review of recent studies on neuronal injury response.
  • Analysis of retrograde signaling pathways.
  • Examination of regeneration-associated gene expression.

Main Results:

  • Retrograde transport of injury signals informs the neuron's cell body about axonal damage.
  • This signaling cascade activates regeneration-associated genes.
  • Enhanced intrinsic growth capacity is observed in injured neurons following signal transduction.

Conclusions:

  • Retrograde injury signaling is a key mechanism for stimulating neuronal regeneration.
  • Understanding these pathways is vital for developing therapies for CNS injuries.
  • Targeting intrinsic growth capacity offers a promising avenue for CNS repair.
