Resumen

Hemos establecido que los nefrocitos de Drosophila (células encargadas del filtrado de la hemolinfa) poseen diafragmas de filtración análogos a nivel molecular, estructural y funcional a los presentes en los podocitos renales, que permiten el paso selectivo de moléculas a la orina durante el ultrafiltrado de la sangre en vertebrados. Este hecho permite establecer a los nefrocitos de Drosophila como un sistema muy útil para estudiar la fisiología renal en los seres humanos, tanto en condiciones normales como patológicas (revisado en Simons, M. and Huber, T. B. (2009). Flying podocytes. Kidney Int 75, 455-7.)
