Abstract
Purpose of Review To review recent scientific advances and therapeutic approaches in the expanding field of type I interferonopathies. Summary Type I interferonopathies represent a genetically and phenotypically heterogenous group of disorders of the innate immune system caused by constitutive activation of antiviral type I interferon (IFN). Clinically, type I interferonopathies are characterized by autoinflammation and varying degrees of autoimmunity or immunodeficiency. The elucidation of the underlying genetic causes has revealed novel cell-intrinsic mechanisms that protect the organism against inappropriate immune recognition of self nucleic acids by cytosolic nucleic acid sensors. The type I IFN system is subject to a tight and complex regulation. Disturbances of its checks and balances can spark an unwanted immune response causing uncontrolled type I IFN signaling. Novel mechanistic insight into pathways that control the type I IFN system is providing opportunities for targeted therapeutic approaches by repurposing drugs such as Janus kinase inhibitors or reverse transcriptase inhibitors.
Human T Cell Leukemia Virus Type 1: Persistence and Pathogenesis

Abstract
Human T cell leukemia virus type 1 (HTLV-1), also known as human T lymphotropic virus type 1, was the first exogenous human retrovirus discovered. Unlike the distantly related lentivirus HIV-1, HTLV-1 causes disease in only 5-10% of infected people, depending on their ethnic origin. But whereas HIV-1 infection and the consequent diseases can be efficiently contained in most cases by antiretroviral drug treatment, there is no satisfactory treatment for the malignant or inflammatory diseases caused by HTLV-1. The purpose of the present article is to review recent advances in the understanding of the mechanisms by which the virus persists in vivo and causes disabling or fatal diseases.
