Abstract

Type I interferon (IFN-I) mediates tissue damage in a wide range of kidney disorders, directly affecting the biology and function of several renal cell types including podocytes, mesangial, endothelial, and parietal epithelial cells. Enhanced IFN-I signaling is observed in the context of viral infections, autoimmunity (e.g., systemic lupus erythematosus), and type 1 interferonopathies, rare monogenic disorders characterized by constitutive activation of the IFN-I pathway. All these IFN-I-related disorders can cause renal dysfunction and share pathogenic and histopathological features. Collapsing glomerulopathy, a histopathological lesion characterized by podocyte loss, collapse of the vascular tuft, and parietal epithelial cell proliferation, is commonly associated with viral infections, has been described in type 1 interferonopathies such as Aicardi-Goutières syndrome and stimulator of IFN genes-associated vasculopathy with onset in infancy, and can also be induced by recombinant IFN therapy. In all these conditions, podocytes and parietal epithelial cells seem to be the primary target of IFN-I-mediated damage. Additionally, immune-mediated glomerular injury is common to viral infections, systemic lupus erythematosus, and type 1 interferonopathies such as coatomer subunit-α syndrome (COPA) and DNASE1L3 deficiency, diseases in which IFN-I apparently promotes immune-mediated kidney injury. Finally, kidney pathology primarily characterized by vascular lesions (e.g., thrombotic microangiopathy and vasculitis) is a hallmark of type 1 interferonopathy adenosine deaminase 2 deficiency as well as of systemic lupus erythematosus, viral infections, and IFN therapy. Defining the nosology, pathogenic mechanisms, and histopathological patterns of IFN-I-related kidney disorders has diagnostic and therapeutic implications, especially considering the likely near-term availability of novel drugs targeting the IFN-I pathway.
