La grasa de los bebés combate la obesidad

Según un grupo de investigadores del Insituto de Cáncer Dana-Farber, en Boston (EEUU), el tejido adiposo marrón, que tiene una alta presencia en recién nacidos donde su función es la de generar calor, podría ser el remedio contra la obesidad y la diabetes.

El estudio, publicado en la revista Nature, describe un método para producir grasa parda a través de la manipulación de células cutáneas de humanos y ratones.

Según cuenta el artículo, los científicos lograron sintetizar tejido adiposo marrón manipulando los mecanismos de las células de la piel. Posteriormente reintrodujeron el tejido en ratones adultos, donde observaron que la grasa parda eliminaba gran cantidad de calorías.

El mecanismo manipulado actúa como un interruptor molecular. Su función es la de generar tejido muscular, pero si se modifica adecuadamente, produce tejido adiposo marrón.

Según afirma el propio responsable del estudio, Bruce Spiegelman "Los resultados muestran la posibilidad de tratar a enfermos de obesidad y diabetes. Podría extraerse tejido cutáneo del paciente, añadirle el interruptor e introducirlo en el organismo para sintetizar grasa parda adicional".
