Inmunoterapia antitumoral NK-CAR: De asesinas naturales a asesinas artificiales.

from Cienciaes.com

Gracias al descubrimiento y comprensión de los mecanismos de acción de las células T citotóxicas (los linfocitos T CD8 activados) y de las células Natural Killer (NK) se han podido desarrollar procedimientos antitumorales muy prometedores que, obedientemente, matan a las células cancerosas. Son los sistemas llamados T-CAR y NK-CAR. Los investigadores han modificado genéticamente esas células del sistema inmunitario de manera que se pueda dirigir su acción contra células tumorales, en particular contra las células causantes de diversos tipos de leucemias. La idea no es otra que la de equipar a estas células con receptores de diseño capaces de enviar una señal activadora asesina cuando detecten a moléculas de nuestra elección, como puede ser un antígeno específico de un tipo tumoral concreto al que las células NK o T CD8 no responden de manera natural. Estos receptores de diseño son los llamados CAR. Habrá que esperar a los resultados de ensayos clínicos para confirmar si esta nueva estrategia antitumoral es segura y tiene éxito.
