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...

Nervous Tissue: Glial Cells

8.8K
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...

Nervous Tissue: Myelin

7.8K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

14.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Area of Science:

  • Neuroscience
  • Mitochondrial Biology
  • Cell Death Research

Background:

  • Cell death, often linked to mitochondrial dysfunction, is a key feature of central nervous system pathologies like stroke and neurodegenerative diseases.
  • Targeting mitochondrial events in cell death pathways presents a promising therapeutic avenue for limiting neuronal damage.

Purpose of the Study:

  • To discuss the biological and structural features of neuroglobin.
  • To explore the mitochondria-related mechanisms underlying neuroglobin-induced neuroprotection.
  • To highlight the potential of neuroglobin as a therapeutic agent for neurological disorders.

Main Methods:

  • Review of existing literature on neuroglobin's role in neuroprotection.
  • Analysis of experimental models demonstrating neuroglobin's effects on cell survival and mitochondrial function.
  • Examination of neuroglobin's impact on the intrinsic pathway of apoptosis.

Main Results:

  • High expression of neuroglobin is associated with preserved mitochondrial function and enhanced nerve cell survival.
  • Neuroglobin exhibits protective effects in various in vitro and in vivo experimental models of cell insult.
  • Inhibition of the intrinsic apoptosis pathway is a primary mechanism of neuroglobin-mediated neuroprotection.

Conclusions:

  • Neuroglobin demonstrates significant neuroprotective capabilities by maintaining mitochondrial integrity and preventing programmed cell death.
  • These findings support the development of neuroglobin-based therapeutic strategies for neurological conditions.
  • Targeting neuroglobin may offer a novel approach to minimize neuronal cell death in stroke and neurodegenerative diseases.
