Abstract
La oligodendrogénesis es un proceso esencial para la formación y el mantenimiento de la mielina axonal y, por consiguiente, para la correcta transmisión nerviosa en el sistema nervioso central (SNC). La esclerosis múltiple (EM) es una enfermedad desmielinizante del SNC caracterizada por muerte de oligodendrocitos (OL),desmielinización y daño axonal, presentando un carácter progresivo, recurrente y neurodegenerativo. La remielinización es el proceso por el cual se restaura la mielina delos axones desmielinizados de manera espontánea, recobrándose la transmisión saltatoria del impulso nervioso. En la EM existe un déficit en el proceso de remielinización, que se cree que es debido a una insuficiencia en la diferenciación dec élulas progenitoras de oligodendrocitos (OPC) y, por tanto, en la regeneración de OL mielinizantes. De esta forma, la búsqueda de moléculas que favorezcan la oligodendrogénesis durante la mielinización del SNC y, de manera más importante, en situaciones de desmielinización, es uno de los retos actuales de la investigación para el tratamiento de trastornos desmielinizantes que actualmente no tienen cura...
Oligodendrogenesis is an essential process for the formation and maintenance of axonal myelin and, consequently, for correct nerve transmission in the central nervoussystem (CNS). Multiple sclerosis (MS) is a demyelinating disease of the CNS characterizedby oligodendrocytes (OL) cell death, demyelination and axonal damage, presenting a progressive, recurrent and neurodegenerative character. Remyelination is the process by which myelin of demyelinated axons is restored spontaneously, recovering the saltatory transmission of the nerve impulse. In MS there is a deficit in the remyelination process, which is believed to be due to an insufficiency in the differentiation of oligodendrocyte progenitor cells (OPC) and, therefore, in the regeneration of myelinating OL. Therefore, the search for molecules that favor oligodendrogenesis during CNS myelination and, more importantly, in situations of demyelination, is one of the current challenges of research for the treatment of demyelinated disorders that currently have no cure...
