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...

Olfactory Receptors: Location and Structure

13.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Anatomy of the Eyeball

11.1K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Regenerative Medicine

Background:

  • Traumatic optic nerve injury leads to irreversible blindness and vision loss due to retinal ganglion cell (RGC) death.
  • Current treatments fail to halt or reverse vision loss after optic nerve injury.
  • RGC axon regeneration is essential for vision recovery but is poorly understood.

Purpose of the Study:

  • To review molecular mechanisms underlying RGC axon regeneration after optic nerve injury.
  • To explore strategies for promoting optic nerve repair and vision restoration.

Main Methods:

  • A comprehensive review of existing research on molecular mechanisms of axon regeneration.
  • Focus on cytokines, signaling pathways, intrinsic growth programs, and inhibitory environments.

Main Results:

  • Identified key roles of cytokines and downstream signaling in RGC intrinsic growth.
  • Highlighted the importance of overcoming inhibitory factors and utilizing axon guidance cues.
  • Findings suggest potential for clinically meaningful optic nerve regeneration.

Conclusions:

  • A combination approach is crucial for promoting axon regeneration and functional vision recovery.
  • Strategies must address growth inhibition, enhance intrinsic growth capacity, and ensure correct axon guidance.
