Una nueva investigación sobre el mecanismo que utilizan algunos tumores para escapar al ataque del sistema inmunitario puede conducir a un diagnóstico más temprano del cáncer de mama, pulmón, colon y otros, así como a mejores estrategias de tratamiento, según escriben en "Nature" investigadores del Fred Hutchinson Cancer Research Center de Seattle (Estados Unidos).
Señalan que muchos de estos tumores producen grandes cantidades de una proteína llamada MIC, la cual puede pasar al torrente sanguíneo. Por ello, análisis de sangre sanguíneos que detecten elevados niveles de la proteína, que se encarga de silenciar a los linfocitos T, pueden indicar la presencia de cáncer.
