Rubicon-deficiency sensitizes mice to mixed lineage kinase domain-like (MLKL)-mediated kidney ischemia-reperfusion injury

Abstract: The cytosolic protein rubicon (RUBCN) has been implicated in the removal of necrotic debris and autoimmunity. However, the role of RUBCN in models of acute kidney injury (AKI), a condition that typically involves necrotic kidney tubules, was not investigated. Here, we demonstrate that RUBCN-deficient mice are hypersensitive to renal damage induced by ischemia-reperfusion injury (IRI) and cisplatin-induced AKI. Combined deficiency of RUBCN and mixed lineage kinase domain-like (MLKL) partially reversed the sensi… Show more

“…Interestingly, and somehow in contrast to a proactive role, MLKL-deficient patients may present with features of neurodegeneration ( 29 ). Beyond the field of neurology, MLKL was reported to be involved in acute conditions such as ischemia-reperfusion injury ( 9 , 28 , 30 34 ). In the preclinical limelight of the growing body of evidence for MLKL as a mediator of diseases, clinical trials employing MLKL inhibitors will be considered.…”

“…STING (stimulator of interferon response cGAMP interactor 1) é uma proteína transmembrana do retículo endoplasmático que induz respostas importantes na defesa contra patógenos, como a produção de IFN do tipo I e indução de xenofagia. No entanto, respostas exacerbadas dessa via contribuem na patogênese de diversas doenças inflamatórias ou autoimunes (HOPFNER;HORNUNG, 2020;MCWHIRTER;JEFFERIES, 2020) Alterações tanto no reconhecimento quanto na degradação das células mortas nos fagócitos provocam o desenvolvimento de processos autoinflamatórios e/ou autoimunes em diferentes modelos murinos (COHEN et al, 2002;LEMKE, 2001;RODRIGUEZ-MANZANET et al, 2010;TONNUS et al, 2022). Nesse contexto, estudos in vitro demonstraram que macrófagos com deficiências em LAP induzem a produção de IFN do tipo I dependente de STING em resposta à eferocitose de células apoptóticas (CUNHA et al, 2018).…”

“…Por outro lado, deficiência em componentes de LAP, como RUBCN, promovem respostas inflamatórias em células mielóides que promovem a eliminação de células tumorais (CUNHA et al, 2018). Além disso, deficiências de LAP estão associados ao desenvolvimento de nefrite crônica espontânea em camundongos envelhecidos (TONNUS et al, 2022).…”
