El yin y el yang de la astrogliosis reactiva
Palabras clave:
“visión neurocéntrica”, astrogliosis reactiva, “visión gliocéntrica”, neuronasResumen
Por mucho tiempo, el estudio del sistema nervioso en la salud y en la enfermedad tuvo una “visión neurocéntrica”, en la que el papel estelar lo acaparaban las neuronas. Aunque las neuronas y las células gliales se describireron a principios del siglo XIX, el estudio fisiológico de la glía comenzó 50 años después. Actualmente, este punto de vista ha cambiado debido a que diversas investigaciones han revelado que la interacción glía-neurona es fundamental en procesos fisiológicos y patológicos, de tal forma que varios neurocientíficos tienen ahora una “visión gliocéntrica”.
