RIPK3 and kidney disease

Abstract

La proteína quinasa 3 que interactúa con el receptor (RIPK3) es una quinasa intracelular que se encuentra a medio camino entre la muerte celular y la inflamación. La RIPK3 contiene un dominio motivo de interacción homotípica de RIP (RHIM), que permite las interacciones con otras proteínas que contienen RHIM, y un dominio de quinasa que permite la fosforilación de las proteínas diana. La RIPK3 puede ser activada a través de la interacción con las proteínas que contienen RHIM tales como RIPK1, TRIF y DAI (ZBP1, DLM-1), o a través de mecanismos independientes de RHIM en un pH intracelular alcalino. La RIPK3 media en la necroptosis y promueve la inflamación, independientemente de la necroptosis, bien a través de la activación de NFκB, o del inflamasoma. Existe evidencia preclínica in vivo de la contribución de RIPK3 a la insuficiencia renal aguda (IRA) y la enfermedad renal crónica (ERC), así como a la transición IRA-ERC derivada de ratones con deficiencia de RIPK3 o del uso de pequeñas moléculas inhibidoras de RIPK3. En dichos estudios, el tener a RIPK3 como objetivo redujo la inflamación, pero la nefropatía mejoró solo en algunos contextos. La traducción clínica de estos hallazgos se ha demorado debido al potencial de ciertas pequeñas moléculas inhibidoras de la actividad de la quinasa RIPK3 para activar la muerte celular induciendo cambios conformacionales de la proteína. Comprender mejor los cambios conformacionales de RIPK3 activadores de la apoptosis, los inhibidores duales RIPK3/RIPK1 o la reconversión de múltiples inhibidores de la quinasa tales como dabrafenib podría facilitar el desarrollo clínico del concepto de la inhibición de RIPK3 para diversas enfermedades inflamatorias, incluyendo las enfermedades renales

Receptor interacting protein kinase 3 (RIPK3) is an intracellular kinase at the crossroads of cell death and inflammation. RIPK3 contains a RIP homotypic interaction motif (RHIM) domain which allows interactions with other RHIM-containing proteins and a kinase domain that allows phosphorylation of target proteins. RIPK3 may be activated through interaction with RHIM-containing proteins such as RIPK1, TRIF and DAI (ZBP1, DLM-1) or through RHIM-independent mechanisms in an alkaline intracellular pH. RIPK3 mediates necroptosis and promotes inflammation, independently of necroptosis, through either activation of NFκB or the inflammasome. There is in vivo preclinical evidence of the contribution of RIPK3 to both acute kidney injury (AKI) and chronic kidney disease (CKD) and to the AKI-to-CKD transition derived from RIPK3 deficient mice or the use of small molecule RIPK3 inhibitors. In these studies, RIPK3 targeting decreased inflammation but kidney injury improved only in some contexts. Clinical translation of these findings has been delayed by the potential of some small molecule inhibitors of RIPK3 kinase activity to trigger apoptotic cell death by inducing conformational changes of the protein. A better understanding of the conformational changes in RIPK3 that trigger apoptosis, dual RIPK3/RIPK1 inhibitors or repurposing of multiple kinase inhibitors such as dabrafenib may facilitate clinical development of the RIPK3 inhibition concept for diverse inflammatory diseases, including kidney diseases
