Glial cells: a secondary actor?

Glia cells have awakened high interest among the scientific community in recent years due to their potential to explain neurodegenerative processes in diseases such as Alzheimer's or Sclerosis Multiple. Glial cells play a multitude of functions that can be summarized in the homeostatic maintenance of the nervous system. It is known that glial cells participate in synaptic processes, known as tripartite synapses.


Glial cells subtypes


There is a high diversity of glial cells, with multiple states. The main known subtypes in the central nervous system of the adult Homo sapiens. They can be observed:


  1. Microglia:

  • (1.1) Activated

  • (1.2) Amoeboid

  • (1.3) Ramified

  1. Ependymocytes

  2. Astrocytes:

  • (3.1) Protoplasmic

  • (3.2) Fibrous

  1. Oligodendrocytes


Each subtype boasts unique characteristics and functions, contributing to the nervous system's architecture and function.

What's truly fascinating is how modern neuroscience is expanding its horizons beyond the conventional focus on neurons and the brain. Researchers are increasingly recognizing the importance of understanding the roles played by glial cells in health and disease, paving the way for novel insights and potential therapeutic avenues.
