Rabphilin involvement in filtration and molecular uptake in Drosophila nephrocytes suggests a similar role in human podocytes
2020
ABSTRACT Drosophila nephrocytes share functional, structural and molecular similarities with human podocytes. It is known that podocytes express the rabphilin 3A (RPH3A)-RAB3A complex, and its expression is altered in mouse and human proteinuric disease. Furthermore, we previously identified a polymorphism that suggested a role for RPH3A protein in the development of urinary albumin excretion. As endocytosis and vesicle trafficking are fundamental pathways for nephrocytes, the objective of this study was to assess the role of the RPH3A orthologue in Drosophila, Rabphilin (Rph), in the structure and function of nephrocytes. We confirmed that Rph is required for the correct function of the en…
Small Rab GTPases in Intracellular Vesicle Trafficking: The Case of Rab3A/Raphillin-3A Complex in the Kidney
2021
Small Rab GTPases, the largest group of small monomeric GTPases, regulate vesicle trafficking in cells, which are integral to many cellular processes. Their role in neurological diseases, such as cancer and inflammation have been extensively studied, but their implication in kidney disease has not been researched in depth. Rab3a and its effector Rabphillin-3A (Rph3A) expression have been demonstrated to be present in the podocytes of normal kidneys of mice rats and humans, around vesicles contained in the foot processes, and they are overexpressed in diseases with proteinuria. In addition, the Rab3A knockout mice model induced profound cytoskeletal changes in podocytes of high glucose fed a…
Papel del complejo de proteínas Rab-Rabphilin en un modelo de daño renal en Drosophila
2019
La enfermedad renal crónica (ERC) es una de las enfermedades más prevalentes en la actualidad, con un 10 % de personas que la sufren en todo el mundo. La aparición de la enfermedad puede deberse a diferentes causas como la diabetes, hipertensión, estado del sistema inmune y genéticas, siendo la hiperglucemia una de las más comunes y responsable de la mayoría de los casos. Esto convierte a la nefropatía diabética en la causa más frecuente de enfermedad renal en etapa terminal (ESRD) en la mayoría de los países. La ERC es progresiva y el tratamiento sólo logra enlentecer su progresión, pero no revertirla. De ahí la necesidad de identificar mecanismos implicados en el daño renal y de encontrar…
