La inmunoterapia del c\u00e1ncer quiere revertir esta inmunosupresi\u00f3n y estimular la actividad de c\u00e9lulas como los LTcs o las NKs para que puedan seguir identificando y eliminando las c\u00e9lulas tumorales y as\u00ed combatir la enfermedad. Un tipo concreto de inmunoterapia utiliza virus oncol\u00edticos, que infectan a las c\u00e9lulas cancerosas para eliminarlas directamente o atraer la respuesta inmunitaria.<\/p>\n<p>Ahora, un grupo de investigaci\u00f3n del IDIBELL y el ICO ha desarrollado un virus oncol\u00edtico concreto, ICOVIR15K-MICAMut, que, al penetrar en las c\u00e9lulas tumorales y expresar su material gen\u00e9tico, atrae y activa las c\u00e9lulas lulas NK. En el laboratorio, los investigadores han comprobado, utilizando ratones como modelo experimental, c\u00f3mo este virus induc\u00eda una respuesta inmunitaria antitumoral m\u00e1s eficiente y un mayor control del crecimiento del c\u00e1ncer. Este resultado abre sus puertas a un futuro ensayo cl\u00ednico.<\/p>\n<p>Los resultados con virus oncol\u00edticos son prometedores, pero todav\u00eda hay que realizar m\u00e1s investigaci\u00f3n para dise\u00f1ar un tratamiento robusto capaz de erradicar un tumor. En este sentido, el Dr. Rafael Moreno, l\u00edder del estudio, asegura que este trabajo \u00abdestaca el papel de las c\u00e9lulas NK en la inmunoterapia y presenta un enfoque innovador que tiene un gran potencial cl\u00ednico\u00bb.<\/p>\n<p><em>\u00a0<\/em><\/p>\n<p><em>\u00a0<\/em><\/p>\n<p><em>El Instituto de Investigaci\u00f3n Biom\u00e9dica de Bellvitge (IDIBELL) es un centro de investigaci\u00f3n en biomedicina creado en 2004.
