Summary
Astrocytes, crucial for brain health, become reactive after injury, forming glial scars. This reactive astrogliosis can contribute to central nervous system (CNS) disorders.
Area of Science:
- Neuroscience
- Cell Biology
- Pathology
Background:
- Astrocytes are abundant glial cells in the central nervous system (CNS) with vital functions.
- Reactive astrogliosis, a response to CNS injury, is a hallmark of lesions.
- Recent advances illuminate astrocyte roles in CNS disorders.
Purpose of the Study:
- To review astrocyte functions in healthy CNS.
- To explore mechanisms and functions of reactive astrogliosis and glial scar formation.
- To define the role of reactive astrocytes in CNS disorders and lesions.
Main Methods:
- Review of current literature on astrocyte biology and pathology.
- Analysis of findings from transgenic mouse models of reactive astrocytosis.
- Integration of clinicopathological data on astrocyte involvement in diseases.
Main Results:
- Reactive astrogliosis is a complex, context-dependent continuum, not a simple response.
- Changes in astrocytes range from reversible alterations to permanent glial scar formation.
- Reactive astrocytes can contribute to CNS disorders through altered functions or detrimental effects.
Conclusions:
- Astrocytes play multifaceted roles in both healthy and diseased CNS.
- Understanding reactive astrogliosis is key to addressing CNS pathologies.
- Targeting astrocyte responses may offer therapeutic strategies for neurological disorders.

Nervous Tissue: Glial Cells
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.

Overview
Neuron Structure
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.

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...
The Blood-brain Barrier
Overview
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
