Este trabajo apoya la hipótesis de la modulación en la expresión de CMH tras la aparición de resistencia a drogas en células tumorales

LA RESISTENCIA A DROGAS MODIFICA LAS CARACTERISTICAS INMUNOLOGICAS DE LOS RABDOMIOSARCOMAS

Los rabdomiosarcomas embrionarios desarrollan resistencia a la quimoterapia convencional debido a la expresión de P-glicoproteína/Mdr1. Dicha resistencia determina el pronóstico de la enfermedad y modifica las características inmunológicas de las células tumorales que aumentan significativamente su expresión de HLA de calse I. Este cambio puede ser de enorme importancia en la determinación de nuevas vías de tratamiento que mejoren su pronóstico.
