Esto es porque los tratamientos da\u00f1an las c\u00e9lulas sanas, como resultado, se espera que los virus modificados gen\u00e9ticamente sean capaces de dirigirse selectivamente a c\u00e9lulas enfermas, y mejorar desde la capacidad de la c\u00e9lula como la forma como responden a diferentes tratamientos.<\/p>\n<p>\u201cEn el laboratorio, utilizamos virus atenuados, es decir, que no son capaces de replicarse para transportar\u00a0material codificado gen\u00e9ticamente\u00a0en los organismos vivos afectados por la enfermedad\u201d, dijo el Dr. Mazahir Hasan.<\/p>\n<p>\u201cEste enfoque abre toda una gama de opciones que, en el futuro, nos permitan tratar y curar diversas enfermedades.<\/p>\n<p>Este funciona como un interruptor gen\u00e9tico \u201con\/off\u201d que se controla qu\u00edmicamente. \u201cEl hecho de que la funci\u00f3n del gen se puede conectar y desconectar de esta manera es de especial valor, y hace que el m\u00e9todo de un candidato perfecto para su uso en la\u00a0terapia g\u00e9nica controlada\u201c, enfatiza el Dr. Hasan.<\/p>\n<p>Cabe destacar, el hecho de que las\u00a0c\u00e9lulas infectadas\u00a0con este tipo de virus modificados no activan cualquier forma de respuesta inmunitaria medible y que su material gen\u00e9tico permanece completamente intacto representa un beneficio adicional.<\/p>\n<p>Sin duda un significativo avance que se espera que al completar con \u00e9xito el paso inicial de las pruebas usando un modelo animal, se sienten las bases para tratamientos gen\u00e9ticos futuros para su uso en\u00a0humanos.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La capacidad de cambiar los genes causantes de enfermedades ha sido una meta para muchos m\u00e9dicos y
