dct:description """Bergmann glial cells, also known as Bergmann glia or Bergmann astrocytes, are specialized astrocytes located in the cerebellum, specifically in the Purkinje cell layer. They were discovered and named after the German histologist Karl Bergmann and are known for their characteristic morphology. Unique to Bergmann glial cells is their long, fibrous processes, which extend through the molecular layer to the cerebellar surface, aligning parallel to the Purkinje cells' dendrites. These extensions play a detailed role in the structural organization and function of the cerebellum.
The primary function of Bergmann glial cells is to support and nourish the adjacent neuronal cells, especially the Purkinje cells. Their strategic arrangements around synapses or nerve junctions also indicate their role in facilitating communication between neurons and in modulating synaptic plasticity. The glial cells remove excess neurotransmitters from the synaptic clefts and thus help maintain homeostasis. An additional important role of Bergmann glia is in the guided migration of granule cells during cerebellar development. This guidance is critical for the proper formation and arrangement of the cerebellar circuitry.
In addition to these roles, recent studies have revealed a vital function of Bergmann glial cells in maintaining the overall health and functioning of the cerebellum. In instances of cerebellar injury or disease, these cells respond proactively and change their morphology and activity, a process known as reactive gliosis. This response seems to protect and restore the neural circuits. However, aberrant activation of Bergmann glial cells has been associated with several neurodegenerative diseases and disorders, such as spinocerebellar ataxia, underscoring their significance in the pathobiology of the nervous system.
