RESUMEN
La concepción del cerebro como un sitio inmunológicamente privilegiado
ha cambiado, a la fecha se conoce que la respuesta neuroinmunológica
es fundamental en el proceso de neurodegeneración, ya
que puede promoverlo o inhibirlo, además de contribuir con la muerte
neuronal. Las células gliales (microglía y astrocitos) son los principales
efectores de la respuesta neuroinmunológica en las enfermedades desmielinizantes,
mediante su activación y liberación de moléculas neurotóxicas
como citocinas y quimiocinas, que originalmente son dirigidas
a incrementar el proceso neurorregenerativo mediante la expresión de
factores de crecimiento que promoverán una remielinización. Así, el
conocimiento de los mecanismos de regulación de la activación de las
células gliales, como la expresión de citocinas, quimiocinas y factores
de crecimiento permitirán el diseño y desarrollo de terapias específicas
de neurorregeneración para las patologías desmielinizantes.
