De hecho, ya se ha iniciado un ensayo clínico para evaluar esta posibilidad, según anuncian investigadores del Baylor College of Medicine de Houston (Estados Unidos).
Publican sus resultados en "Cell". En estudios previos habían observado que ratones manipulados para carecer de leptina, hormona que interviene en la regulación del peso, no sólo son más obesos que los roedores normales, sino que presentan huesos más fuertes. En posteriores experimentos han comprobado que los bloqueadores beta inhiben un proceso de señalización dependiente de la leptina que actúa sobre los osteoblastos y que impide la formación de nuevo tejido óseo.
