Cient\u00edficos de la Universidad de Tel Aviv afirman haber avanzado de forma significativa en el desarrollo de una \u00abnano-vacuna\u00bb contra el melanoma.<\/strong><\/em><\/p>\n

El melanoma es el tipo m\u00e1s grave de c\u00e1ncer de piel, formado en las c\u00e9lulas que producen melanina, el pigmento que da color a la piel.<\/p>\n

Los investigadores han realizado ya pruebas exitosas en ratones y la nano-vacuna ha demostrado ser efectiva en prevenir el desarrollo del melanoma as\u00ed como en el tratamiento de tumores primarios y met\u00e1stasis que resulta de la enfermedad.<\/p>\n

La investigaci\u00f3n, publicada este lunes en la prestigiosa revista Nature Technology, se enfoca en la utilizaci\u00f3n de una nanopart\u00edcula que sirve como base para esta nueva vacuna.<\/p>\n

\u00abLa guerra contra el c\u00e1ncer en general, y el melanoma en particular, ha avanzado a trav\u00e9s de los a\u00f1os con una variedad de modalidades de tratamiento como cirug\u00edas, quimioterapia, radioterapia e inmunoterapia, pero el uso de vacunas, que se ha probado tan efectivo contra varias enfermedades virales, no se ha materializado a\u00fan contra el c\u00e1ncer\u00bb, explica la Prof. Ronit Satchi-Fainaro, directora del departamento de Fisiolog\u00eda y Farmacolog\u00eda y jefa del laboratorio de Investigaci\u00f3n del C\u00e1ncer y Nanomedicina en la Universidad de Tel Aviv.<\/p>\n

Seg\u00fan afirman las investigaciones, los cient\u00edficos han logrado aprovechar peque\u00f1as part\u00edculas de unos 170 nanometros de un pol\u00edmero biodegradable que luego unieron a dos p\u00e9ptidos que se expresan en las c\u00e9lulas del melanoma. Estas nanopart\u00edculas fueron inyectadas en los ratones que portan el melanoma.<\/p>\n

\u00abEstas nanopart\u00edculas actuaron de forma similar a vacunas conocidas para enfermedades virales. Estimularon el sistema inmune de los ratones y las c\u00e9lulas inmunes aprendieron a identificar y atacar a las c\u00e9lulas que conten\u00edan los dos p\u00e9ptidos, es decir, las c\u00e9lulas del melanoma. Esto quiere decir que desde ese momento el sistema inmune de estos ratones atacar\u00e1 las c\u00e9lulas del melanoma si aparecen en el cuerpo\u00bb, explica Satchi-Fainaro.<\/p>\n

\u00abNosotros creemos que nuestra plataforma puede ser tambi\u00e9n factible para otros tipos de c\u00e1ncer y que nuestro trabajo es un fundamento s\u00f3lido para desarrollar otras nano-vacunas para el c\u00e1ncer\u00bb, agreg\u00f3.<\/p>\n

Seg\u00fan el Centro de Prevenci\u00f3n y Control de Enfermedades (CDC), la incidencia del melanoma se ha duplicado durante las \u00faltimas tres d\u00e9cadas en Estados Unidos y cada hora del d\u00eda una persona muere a causa del melanoma.<\/p>\n

Seg\u00fan la fundaci\u00f3n de c\u00e1ncer de piel, se estima que este a\u00f1o ser\u00e1n diagnosticado alrededor de 190.000 casos de melanoma en Estados Unidos.<\/p>\n
